PRESIDENT’S MESSAGE
The Power of Potential
W
hile each Commencement ceremony is a special celebration, this year’s event was particularly meaningful for me. Four years ago, I arrived at Harvey Mudd College along with the Class of 2010. It has given me such joy to spend the last four years with these young women and men and watch them grow into remarkable individuals. I have so many memories from that first year: learning their faces and names; discovering the different personalities of the dorms; being pranked for the first time (a reflecting pond in my office!); and getting to know our amazing faculty, staff and alumni and how much they care about the mission of our College. I remember the trip to the Grace Hopper Conference in San Diego with 15 first-year students and the strategic planning workshops in which the entire campus community participated that fall. It was during those workshops that Freeman Hrabowski, III, first spoke on campus and made an indelible impression that undoubtedly led to his selection as this year’s Commencement speaker and as the recipient of an HMC Honorary Doctorate degree (see page 2). Most of the Class of 2010 are entering Ph.D. programs at top universities or starting jobs at leading technology companies. Some will be teaching math and science with Teach for America; others are launching a company or exploring the world. Whether they become teachers, entrepreneurs, lawyers, doctors, artists, mathematicians, engineers or scientists (or several of the above), I am confident they will understand and pay attention to the impact of their work on society. During this time of great concern over finding plentiful and safe resources to provide the energy infrastructure for our nation, educated engineers, scientists and technologists are in great demand. Our Department of Engineering recently completed a faculty search that will bring to campus this fall a new faculty member whose specialty is energy issues: Adrian Hightower is a materials scientist who studies and designs nanostructured electrodes for fuel cells and rechargeable batteries. He has been recognized for
the development of community-based renewable education programs throughout Los Angeles and West Africa. As you may have read in past Bulletins and on our website, many of our students are doing research with faculty on solar, geothermal and other energyrelated projects (for the latest, see page 12). Also in this issue, we are highlighting alumni who are working on important research and potential solutions to some tough energy dilemmas, specifically solar technology. Stay tuned for information about the Dr. Bruce J. Nelson ’74 Distinguished Speaker Series, which will bring to campus this fall several high-profile energy pioneers. We owe you, our friends and supporters, a debt of gratitude for all that you have done and continue to do to support our talented students, our prestigious faculty and the College’s infrastructure and activities. As we close fiscal year 2009–2010—in an economic climate which continues to be challenging for so many non-profits— alumni giving increased by a remarkable three percent to 36 percent, while the number of parent donors reached an all-time high. The HMC Board of Trustees continued to lead the way with gifts exceeding $2 million for the second year in a row. Their generosity seems to have inspired other donors who increased their support over last year. As a mission-driven institution, it is very encouraging to see how many alumni, parents and friends are committed to achieving the College’s goals. My four years spent alongside the Class of 2010 have been full of hard work, excitement, achievement and fun, as well as the occasional challenge. Our graduates have the potential to make significant and lasting scientific and technological changes. With your continued support, Harvey Mudd College can nurture many more potential future leaders.

High Marks The results from several national surveys are out, and Harvey Mudd College ranks high Princeton Review– Top 20 College For the 14th consecutive year, Harvey Mudd College was named by The Princeton Review as one of the nation’s best institutions for undergraduate education. HMC is featured in the 2011 edition of its annual guidebook, “The Best 373 Colleges.” When compared to the other 373 colleges in this year’s guidebook, HMC was the only college of math, science and engineering to make the Top 20 lists in two of the key academic categories: “Professors Get High Marks” (ranking 10th), and “Most Accessible Professors” (ranking 14th). HMC also made the Top 20 list in the category of “Students Study the Most” (ranking 3rd). According to a current student quoted in the profile, HMC’s curriculum “teaches way more math and science than you knew existed, then adds one-third humanities on top of if it” and “prepares undergraduates for both industry and grad school.” Reflecting on the student body, yet another student noted that there has been a “strong effort to recruit talented under-represented groups.” HMC has been extremely successful in recruiting more women, who make up 51% of the class of 2014. On a scale of 60-99, HMC received an overall academic rating of 99, the highest possible score. Admission received an overall rating of 98, with Financial Aid receiving an overall rating of 97. Other overall ratings were high in the categories of “Quality of Life” (88) and “Green” (80).
PayScale– Highest earners in the nation The highest earning college graduates in the U.S. come from Harvey Mudd College, according to data released in July by PayScale, an online salary information company, in its 201011 College Salary Report. HMC graduates earn on average $126,000 mid-career, beating out MIT, Caltech, Harvard and Princeton. HMC had the highest median salary of all colleges in the study, as well as the No. 1 ranking in the two categories in which it falls, liberal arts colleges and engineering colleges. Analysts collected data from 999 bachelor’s degree institutions in the last year and tracked median salaries of employees who graduated in the last five years as well as median mid-career salaries of graduates with more than 10 years of experience in a given field. While mid-career salaries

fell 1.5% overall between 2009 and 2010, engineers, scientists and mathematicians continued to earn top salaries.
Forbes–Top 25 In its list of America’s best colleges, Forbes ranked HMC No. 22 out of a list of 610 schools. Forbes’ rankings are based on the quality of the education colleges provide, the experiences of the students and how much they achieve.
New to the HMC Board The HMC Board of Trustees, made up of 33 individuals who direct the policies and funds of the institution, added several new members recently. Nabeel Gareeb ’86/87 (engineering) is a dynamic leader who has transformed companies with his expertise. From 2002 to 2008, Gareeb steered the St. Peters, Mo.-based silicon wafer manufacturer MEMC from a modest concern to a $2-billion-peryear semiconductor industry powerhouse. He is the former chief operating officer of International Rectifier Corp. Jonathan Mersel ’75 (physics) is the outgoing past president of the Alumni Association Board of Governors (AABoG). He is a former chair of the Alumni Fundd Committee and has been a member of AABoG since the 1980s, having held the positions of secretary, treasurer, vice president and president. He is a principal engineer at Northrop Grumman Corporation. Peter Muller is a senior advisor of Morgan Stanley and head of Process Driven Trading, a proprietary trading group which he founded in 1992. He is also co-founder and chairman of the Investment Committee of Chalkstream Capital Group, an investment firm. He serves on the Leadership Council of the Robin Hood Foundation and on the board of Math for America. He graduated with honors with a B.A. in mathematics from Princeton University. Christopher Seib ’00 (engineering) is the chief technology officer and founder of InstaMed, the industry-leading healthcare payments network and platform. He was previously an executive in Accenture’s Health and Life Sciences practice. He joins the board as one of HMC’s young alumni trustees, a position that carries a three-year term.

Celebrating Students and Sponsors This past spring, current President’s Scholars, finalists for the 2010–11 President’s Scholars Program (PSP) and program donors gathered for the annual President’s Scholars Recognition Dinner. The event was created to recognize the corporations, foundations and individual donors that sponsor this important program. Initiated in response to the College’s strategic planning initiative HMC 2020, PSP provides four-year, full-tuition scholarships for highly qualified students who are members of groups traditionally underrepresented on campus and in the fields of science and engineering. This includes a wide range of students, such as women, ethnic minorities, students from rural areas and those who are the first in their families to attend college. During the dinner, three current President’s Scholars Katarina Hoeger ’13, Guillermo Martinez-Garcia ’13 and Dustin Zubke ’13—spoke about how the President’s Scholars Program has helped them achieve their academic and personal goals. Also honored was the second graduating class of President’s Scholars, to whom President Maria Klawe awarded pins as a symbol of their accomplishments.

Generosity and Innovation Mark Spring Events Global Clinic Supported by Vickery Gift The Vickery Family was recently honored for its $1 million contribution to the Harvey Mudd College Global Clinic Program. John Vickery ’91, son of the late Robert and Joan Vickery who bequeathed the generous endowment, and his wife, Yasemine, accepted an award on his parents’ behalf at an event on campus June 7. Robert J. Vickery was an aerospace engineer and Joan Vickery was, arguably, one of the world’s finest mathematicians in software development. The couple said they were proud that their son, John, flourished in the intense and incredible atmosphere of Harvey Mudd College. They loved the Clinic Program and watched how it helped their son put his education into practice. It was witnessing this transformation that inspired them to give so generously to the Global Clinic Program. They knew that their gift would help talented students realize their potential. Robert Vickery passed away in 1996 and Joan Vickery passed away last year. In an interview with the Claremont Courier, John Vickery remarked, “I am absolutely thrilled that my family is able to do this. I do remember the things I got out of my Clinic experience; it changed my life.” Global Clinic Director Lisette de Pillis remarked that the endowment will help support the recruitment of more students into the Global Clinic program. “This year alone three projects are being funded. Without the gift, we would not have been able to run more than one project.” The Department of Engineering began the Global Clinic Program in 2005 to prepare students to function as innovative engineers and scientists in a global context. Built upon HMC’s internationally recognized Clinic Program, the Global Clinic supports long-term sponsored engineering and science projects in which teams of HMC students collaborate with teams of students from partnering schools in Central and South America, Asia and Europe.

Water reclamation, or the reuse of highly treated wastewaters, potentially can provide new supplies equal to approximately 50 percent of Southern California’s water consumption. The novel technology MicroMedia Filtration (MMF) has developed could help the region move closer to this goal. MMF was one of two companies honored for exceptional energy-saving devices at the 17th Annual TechAmerica High-Tech Innovation Awards co-sponsored by TechAmerica, the nation’s largest technology trade association, and Harvey Mudd College. MMF received the HMC Green Engineering Award for its wastewater treatment and renewable energy technology. A leader in the field of water reclamation, MMF has created an innovative three-part process: Solids Separator, which removes suspended solids from the raw stream, the Modular Filter, a continuously cleaning media filtration system, and the Energy Conversion System, which transforms fresh solids into various energy end products. The result is a modular, expandable, economical and environmentally friendly method for creating reusable water that consumes less than one-fifth the electricity of conventional systems. Teridian, a semiconductor company, received an Award of Merit for its computer chip which measures energy consumption data in real time.

A key appointment is enabling Harvey Mudd College professors Ran Libeskind-Hadas (computer science) and Michael Orrison (mathematics) to provide opportunities for HMC and other North American students of computer science, engineering and allied fields to spend a semester of study in Budapest, Hungary. The two professors are among the founding members of the advisory council of the Aquincum Institute of Technology (AIT) study abroad program in Budapest. As North American codirectors, Libeskind-Hadas and Orrison will join colleagues from Franklin W. Olin College of Engineering, Princeton University, Rensselaer Polytechnic Institute, Smith College, Swarthmore College and Williams College to provide ongoing collaborative advice for AIT and guidance on Michael Orrison and Ran Libeskind-Hadas curriculum and related aspects of the program, which features a novel blend of courses in foundations of computing, design and entrepreneurship. Libeskind-Hadas said, “There are very few study-abroad programs that focus on computing and engineering, fewer yet that meld the design and business components into the curriculum, and perhaps no other program that does this in English in a non-English speaking country.”
What Makes a Genius? Arthur Benjamin, HMC’s resident “mathemagician,” was featured on the Science Channel on August 16 in the U.S. premiere of the BBC program “What Makes A Genius?” The documentary featured Benjamin along with an impressive line-up of researchers and artists, including neurobiologist Manuel Casanova of the University of Louisville who claims to have detected differences in brain structure that may account for unusual intelligence, and Elly Nedivi of MIT, who may have found a gene tied to learning. During his segment, Benjamin amazed BBC host Du Sautoy and several passersby in a Boston train station with a demonstration of his impressive mathematical skills.

Next-generation Recording In May, 2010, Professor of Engineering Emeritus James Monson attended the ninth Perpendicular Magnetic Recording Conference in Sendai, Japan. In 1984, Monson participated in some of the early research on perpendicular recording in Shun-ichi Iwasaki’s laboratory at Tohoku University in Japan. It took a long time for perpendicular recording technology to overtake conventional longitudinal magnetic recording in the magnetic data storage hard disk environment. For the last two years, however, virtually all hard disk drives manufactured have used perpendicular magnetic recording. A number of HMC alumni—including Bob Fung ’81, Vince Tobin ’83 and Jason Goldberg ’94—have participated in the development of perpendicular magnetic recording technology.
Green Chemistry for Undergrad Labs Recent graduates who worked in the lab of David Vosburg, assistant professor of chemistry, have had their work published in the Journal of Chemical Education. The articles describe efforts to develop innovative green chemistry experiments for undergraduate teaching labs. In one case, students make the anti-coagulant (blood-thinning) drug warfarin in a single catalytic step with greater purity than if the drug were prescribed. In another article, students describe using an enzyme from horseradish to couple two molecules of vanillin (from vanilla) to form divanillin, which can enhance the flavoring properties of vanillin. Vosburg said, “Each of these experiments has been optimized to reduce energy and chemical

waste while illustrating important chemical concepts and bringing modern chemistry into undergraduate laboratories.” The student coauthors are Terence Wong ’09 and Camille Sultana ’10 (for warfarin) and Rachel Nishimura ’09 and Chiara Giammanco ’10 (for divanillin). Rachel Nishimura ’09 worked in Prof. Vosburg’s lab during summer 2008 on a divanillin experiment. Their work was recently published in the Journal of Chemical Education.
In Memoriam Graydon Bell, physics HMC’s first research program in physics was Graydon D. Bell’s work in astrophysics. His research over many years received National Science Foundation (NSF) support, involved many HMC physics majors and led to a number of publications, one of which appeared in the Proceedings of the Royal Society with Greg Lyzenga ’75, now professor of physics, as co-author. “Gray brought with him a vision for excellence that helped shape the department and College we know today,” said Robert Cave, vice president for academic affairs and dean of faculty. Bell, 87, one of the College’s founding faculty members, died July 20, at his home in Claremont. He arrived at HMC in 1957 from Caltech. He had previously taught at Robert College in Istanbul and served in the Army Air Corps. During his time at HMC, he served as physics department chair (1971–1981) and chair of the faculty (1985–1988). An authority in the field of optics and spectroscopy, the interpretation of interaction between matter and radiation, Bell received an NSF research grant in 1978. His yearlong research as part of the U.S.-Australia Cooperative Science program, helped to improve the quality of undergraduate teaching at HMC by providing models to upgrade HMC lab courses along with specific concepts for student research. He retired from the college in 1988. Read about the first six years of the HMC Physics Department in Bell’s own words at www.hmc.edu/academicsclinicresearch/academicdepartments/physics/history/earliest.html.
Thomas Woodson, engineering Thomas Theodore Woodson, senior professor of engineering emeritus and former Engineering Clinic director, died June 11 in Claremont, Calif., at the age of 100. Sam Tanenbaum, professor of life sciences and engineering and dean emeritus, who, with Woodson, initiated the HMC Mathematics, Engineering, Science Achievement (MESA) program in 1978, said, “Tom was a great designer and engineer, but he was also a wonderful person with a strong moral commitment to serve society—whether that meant motivating and providing opportunities for low-income high school students to become engineers through the MESA program, arranging probono Clinic projects to help handicapped children, or building homes for low income families with Habitat for Humanity.” Woodson arrived at HMC in 1969 and chaired the engineering department from 1972 to 1973. As director of the Engineering Clinic from 1972 to 1977, he is credited with significantly accelerating the growth of the program. He retired as Clinic director in 1977, but continued to teach part time and twice more led the Engineering Clinic in 1980–81 and 1984–85. John Molinder, James Howard Kindelberger Professor of Engineering, remarked of his friend Woodson, “Tom had incredible energy and was not one to waste time. Finishing a conversation with him often involved following him part way to the next activity on his agenda. He is one of the people I look to as models of how to live life to the fullest.”

Celebrating 40 years
First-Class Chemist Jerry Van Hecke ’61, Donald A. Strauss Professor Chemistry, is not just celebrating 40 years as an HMC faculty member. Next year, he will celebrate the 50th anniversary of the Founding Class of HMC, of which he is a member. The former-student-turnedfaculty-member—who chose his major by flipping a coin and went on to earn his B.S. with distinction—is a revered professor, prolific research scientist, and a tireless alumni volunteer who believes the HMC chemistry department is one of the best in the world. After earning an A.M. and Ph.D. at Princeton, Van Hecke worked for Shell Development for four years. He has watched the student population change from his era, when the majority of students were children of “blue-collar” workers, to the present. “Current students have quite a different college expectation beyond simply earning a degree.” “From the point of view of a faculty member and a member of the Founding Class, the biggest change is size of the student body and of the faculty,” says Van Hecke. “With the faculty size increasing from 40 or so in 1970 to now more than 80, life has become more formal. When the student body size was on the order of 400, I knew the name and face of every student. That is not true today.” The biggest change in the college world, and everywhere else, says Van Hecke, has resulted from the introduction of the personal computer and other electronic devices like cell phones.

faculty, most of the original members of the engineering faculty, and key trustees, including Molinder: “I knew right away that this was Henry Mudd, has John a very special place...” given me a special perspective,” he says. “Faculty colleagues and staff across the College have inspired me. Of course, interacting with so many students, alums and some of their children who became students and alums, has been and continues to be the highlight of my career. It has been rewarding so see so many of my former students become highly successful in a wide variety of fields and maybe to have provided a stepping stone here and there.”

John Molinder arrived at HMC in 1970 for what he was told was a two-year temporary position. He said he’s glad the College decided to keep him around. “I knew right away that this was a very special place when Jean Platt greeted me by name in downtown Claremont a couple of weeks after I arrived,” said Molinder, chair of the engineering department from 1983 to 1993 and current James Howard Kindelberger Professor of Engineering. For over 20 years, he was a member of the technical staff, Telecommunications and Data Acquisition Engineering Office at the Jet Propulsion Laboratory, where he has been involved with NASA’s Deep Space Network. He spent one year as a visiting professor at Caltech, one year as a principal engineer at Qualcomm, and nearly one year as a contractor at Boeing Satellite Systems. “Having the opportunity to know a number of the founding
But the computerinduced change was foreshadowed by the hand-held calculator, the impact of which is probably overlooked in this era of the computer. “What I would Jerry Van Hecke: “The best improvements at HMC are have wanted to have yet to come...” as an HMC student that I did not was a hand-held calculator,” he says. “Students today have no appreciation of the calculational effort it took with a mechanical adding machine—even if you had access to one—to determine the slope and intercept of a linear regression line, even for five data points.” Another important change occurring today, says the recipient of HMC’s Henry T. Mudd Prize (2000) and Outstanding Alumni Award (2001), is the recognition of the importance of research and outstanding teaching. “The College’s support of both has much improved.” “The best improvements at HMC are yet to come and will occur when we realize that we are a 50-year-old institution that needs to move toward its new challenges with the confidence of an established entity, not one struggling to find its place,” Van Hecke says.

Esteban Sandoval, maintenance mechanic, has a knack for remembering names, fixing odd maintenance problems, and telling great stories. As of this year, he now has 40 years worth of stories to share. Sandoval’s efforts and longevity were first rewarded in 1998 when he received the Mary Binder prize, which celebrates outstanding staff members. In addition to his HMC job, Sandoval drives a produce truck in Upland. Remarkably, he has been in that business for 24 years. His longevity at both jobs was never anticipated. “By the time I realized how long I’d been here, the time had caught up with me,” he says. Sandoval proudly notes that he has never had to Esteban Sandoval: “I will be here as long as I am able to work.” use disability insurance and has never missed a day of work because of an injury. “You can always count on Esteban to get a job done,” says Isabel Jordan, friend and co-worker.
“He is a man of integrity, generosity and kindness,” says Theresa Potter, assistant vice president for facilities and maintenance. “When I first came here, there were only four dorms and mostly all the students were male,” Sandoval says, adding that the students seemed older then. “They dressed in suits. Students today seem so young!” But while students graduate and the campus changes through the years, Sandoval remains a constant at Mudd. Last spring, when Sandoval was walking out of the dining hall at lunch, he heard someone shout his name and was greeted by a smiling face that was vaguely recognizable. “You’re still here! You worked in East dorm when I was here!” said the unbelieving former student from the ’70s. Sandoval was caught off guard, mainly because the student remembered his name. “It meant a lot to me that he remembered I was here and remembered my name,” he says. Sandoval says the main purpose of his job is to serve the students in any way possible. “I will be here as long as I am able to work.” —Lyndsay Taylor

Dueñas encouraged props, costumes and cheesy gimmicks as well as Mudd-like quotes for his 3-D yearbook, which was created with the help of students who he hopes will produce another 3-D yearbook next year. In addition to the yearbook, seniors received a DVD containing highquality digital copies of the photos in various 3-D display formats.

BRAINpower Recent student research projects during spring and summer tackle energy dilemmas, sustainability and more. As part of a class project, four teams set out in a search for more sustainable ways to generate electricity from ocean waves. One of the teams explored transforming wave motion energy to rotational energy and finally into electrical energy. Seniors Rob Best, Ian Bullock, Marco Fernandez and exchange student Laurent Chris Goudet reported that the tidal turbine prototype (shown right) that they developed was “potentially a great resource for harnessing the renewable, ‘green’ energy of the ocean.”

A six-member Clinic team addressed a serious problem—how to clean up underwater oil spills. The current method to recover underwater oil employs divers, who manually scour the polluted area in darkness, sucking up water and oil with vacuum hoses attached to pumps on the surface, a method with many limitations. Client SEAmagine requested a vacuum system that could be operated from inside a submarine, allowing for longer missions at deeper levels than divers can attain. The Clinic team devised a feedback system that allows the submarine operator to determine when the vacuum hose is recovering oil.

Their dance video game for senior citizens, entitled Senior Prom—based on the popular Dance Dance Revolution arcade game—involves an instruction screen and brightly colored socks that are tracked by cameras which help users take the right steps. The project, funded by a Google grant, is a continuation of work done by a previous group of students. This year’s team worked to improve the coding and the prototype and tested their results on willing participants at a local retirement home. “[The seniors] seemed to enjoy trying out the games, and had a lot of helpful comments about their experience,” said Ferraro.

Dalar Nazari ’13, Ethan Ritz ’12, Ethan Susca ’12 and Michael Loy ’13 worked on a way to separate gases using composite membranes. “Industries use intensive methods of separating gases,” said Susca. “In the traditional industrial gas separation process, gases are cooled using lots of energy until one gas becomes a liquid. Then the liquid is separated from the gas.” The HMC team worked on what could potentially be a more efficient method: filters that separate one gas from the other. By creating composite membranes containing organic nano-particle filters, the team sought to reduce the energy used in the gas separation process. Left, Nazari looks at slices of a packing model that represents a Poly(4-methyl-2-pentyne) membrane. “We use such computer models to get an atomic view of the packing structure of polymer membranes that we experiment with in the lab,” she said.

Reckoned With Faculty quintet debates merits of various energy sources Written by Rich Smith
The HMC professors debating America’s energy future scored impressive points on behalf of their favorite renewable or non-renewable power source during a lively exchange this past spring organized by HMC’s Engineers for a Sustainable World/Mudders Organizing for Sustainable Solutions (ESW/MOSS). First up was economics professor Gary R. Evans offering his thoughts on natural gas. It’s a Natural In its favor, “natural gas is relatively clean compared to coal” as an electricity-generating fuel, Evans said. Also, “there’s an abundance of it,” with new sources continuing to be discovered. And, it’s comparatively cheap, with prices currently near historic lows. Although lawmakers and regulators aim to curb natural gas consumption by mandating greater use of alternative energy, Evans expressed confidence that the resource will be “a significant part” of the energy picture for generations to come. The nuclear option Don’t rule out nuclear energy as one to give natural gas a run for the money, said Richard Haskell, professor of physics. The biggest thing nuclear energy has going for it, he said, is its very minimal CO2 impact on the planet. Still, it does have a rather serious eco-drawback, namely, radioactive waste. “Between 95 and 98 percent of radioactive waste in this country is stored at the site of production,” Haskell said. Unfortunately, “we really haven’t figured out what to do with it.” One option might be to reuse at least some of the waste as reactor fuel; another would be to switch from fission- to fusionmade nuclear energy, and in so doing, foreclose the further creation of radioactive wastes, he said.

Joining the air force Wind is the least-expensive renewable energy source, physics Professor Peter Saeta asserted. It also is the nation’s fastest-growing: Saeta cited figures that show wind-energy production increasing at an annual rate of about 45 percent. Recent updates to the National Renewable Energy Laboratory’s maps of U.S. wind capacity reveal that some of the best places to situate wind farms are in the Plains states and the Midwest, while many of the poorest are along the eastern seaboard. The problem with this, as Saeta pointed out, is that windgenerated electricity must travel potentially very long distances before it reaches the locales where the biggest demand for it exists.

Wave of the future Charles Thangaraj, adjunct professor of engineering, champ-ioned oceanic wave energy. It is estimated that ocean waves pack 1,000 times the energy density of wind, meaning a single wave-energy farm could be a fraction of the size of a wind farm in order to generate a comparable amount of electricity. Thangaraj remarked that HMC students have been working on a prototype system to harness wave energy. (see page 12) He also described another approach currently being tried off the coast of Portugal, “basically a big tube, hinged at certain points” so that it can oscillate with the cresting and falling of each wave rolling past; an internal mechanism translates the oscillation into linear motion which then turns a generator. Wave-harnessing technology might someday prove more costeffective to implement and operate than other alternative energy sources owing to its simplicity, he added.

Rays of hope Hal Van Ryswyk, professor of chemistry, took a stand for solar energy. “More [energy in the form of ] sunlight strikes this planet in an hour than humankind uses in a year,” he said. Unfortunately, conventional silicon-based photovoltaic cells are not a particularly cost-efficient mechanism for converting solar radiance to electricity, he lamented. Better might be solar cell-infused paint, Ryswyk said. Solar paint, he said, utilizes dye-sensitized cells configured in inorganic arrays of non-sunlight-absorbing semi-conductors which then serve as a template for absorbing-dyes capable of creating electricity. Solar paints at this stage of development yield a photonto-electron conversion that is only about 10 percent efficient. However, “there is real hope that they’ll become a disruptive technology once they reach about 20 percent efficiency,” he said, adding that the cost should be in the vicinity of a dollarplus-change per square meter of coverage. The renewable energy winner? As Van Ryswyk put it, “There is enormous potential in solar, wind, waves and in nuclear energy, and I think they all have a place in our energy future.”

time-honored
technology shines 200 years later, the Stirling engine finds its place in the sun. Written by LINLEY ERIN HALL ’01 Photography by KIMBERLY TESKE FETROW
A nearly 200-year-old invention, the Stirling engine, is the basis for the PowerDish™, one of the newest—and hottest—solar power technologies. Maury White ’61, chief technology officer and principal founder of Infinia Corp., has spent his career developing and refining Stirling engines for a wide variety of applications. Now his efforts have the potential to pay off in a big way, not only for him and his company but for the planet as well. “I’ve talked about just retiring,” White says, “but I’m really seeing so much of what I’ve spent 44 years doing finally coming together, and I think I still can help carry it over that edge.” Robert Stirling invented his eponymous engine in 1816. It’s a closed cycle, externally heated and cooled system with a gaseous working fluid. A displacer uses temperature differences to create a pressure wave, which moves a piston to generate power. Infinia focuses on free-piston Stirling engines, which have no parts that rub against each other and thus require no maintenance.
PowerDishes can produce 3kW grid quality power with a conversion efficiency of 24 percent.

Harvey Mudd College
SUMMER 2010
Furthermore, Stirling engines can be designed to use just about any heat source, which makes them excellent components for alternative energy technologies. The PowerDish looks like a satellite dish. A solar concentrator—a mirrored dish—collects the rays of the sun and focuses them on one side of a Stirling engine. A linear alternator generates AC power within the hermetically sealed engine. The PowerDish can produce 3 kW grid-quality power with a conversion efficiency of 24 percent, much higher than the photovoltaic systems available today. White began working on Stirling engines during an internship with Atomics International that became a full-time position. After a few years, he joined a new Stirling engines group at Douglas Aircraft. This group eventually shifted to the University of Washington and then was spun back out into industry as Stirling Technology Company, later renamed Infinia. “Over the years, I’ve had just about every job within the program and have been able to adapt to different requirements at different times,” White says. Most of the engines White has worked on were intended for aerospace or medical applications. However, these projects laid important groundwork for the PowerDish. Research on a Stirling engine to power an artificial heart was particularly crucial. If such an engine breaks down, then the patient could die. Thus, White and colleagues developed extremely reliable engines, one of which ran in the laboratory for more than 11 years with no maintenance and no degradation in performance. The PowerDish is expected to have a lifetime of 25 years with occasional replacement of coolant and fan as the only maintenance necessary.
Maury White ’61 is exploring solar technology for the next generation and beyond.
The PowerDish is currently in use in pilot installations. Infinia hopes to begin large-scale production later this year by taking advantage of unused capacity in U.S. auto parts manufacturing plants. The main materials in the PowerDish—steel, aluminum, copper, glass—are the same as those in car parts, and they also need stamping, casting and other similar manufacturing processes. Thus, a machine that stamps interior door panels for cars also produces the ribs that support the solar concentrator. Companies that make rear view mirrors likewise produce mirrors for the concentrator. “It’s very much taking the automotive supply chain and using the established machine tools and infrastructure that they have and just getting some customized tooling.” Because of this, White says, “We are, I think, the only solar technology that can scale within a very short period of time to as high a quantity as the market will bear.” As exciting as the PowerDish is, White spends most of his time looking ahead, working on research and development for
new products. One of these is a 30 kW solar dish that utilizes a multicylinder free piston Stirling engine that White patented four years ago. He is also developing a PowerDish that can store thermal energy to provide electricity after dark, generators for advanced military operations, a combination Stirling engine/ Stirling refrigerator, and a Stirling generator heated by an anaerobic digester for use in developing nations. “[Our CEO] wanted me to get out there thinking not just about the next generation of the technology and applications but two generations out,” White says. “That’s the kind of thing that I’ve been able to do over these past few years, and it has generated what promises at this point to be some very successful applications.”

Al ha, green Treasa Sweek ’99 is introducing sustainable
design to diverse audiences.
Written by STEPHANIE L. GRAHAM
PALADINO AND COMPANY
The headlines are filled with news of the green building industry—LEED ® *-certified buildings get recognition, architects are lauded for using the latest green technologies, organizations are praised for updating their facilities to be more green. But there was a time when the industry progressed “Mudd’s engineering and math curquietly with often little attention riculum gave me more than I need to understand building science and apply paid to developments. Treasa it to green buildings.” –Treasa Sweek ’99 Sweek ’99 remembers those times. She’s been in the green business since she began working with fellow alumni Malcolm Lewis ’67 and Gail Stranske ’98. They recruited her during an HMC career fair to work for sustainability and energy efficiency company CTG Energetics, where, at the time, Lewis was chairman and CEO (he is now president). Stranske is currently a project engineer. Sweek has always considered the work in the green industry exciting, and it is even more so now that the movement toward sustainable practices and technology has gained momentum, particularly in education and the corporate world. After working at CTG for several years, Sweek moved to Washington state to join Paladino and Company, an internationally recognized green building consulting firm. She’s pleased to be working in a state that long ago recognized the benefits of a more sustainable lifestyle. “The region has an environmental focus going back decades,” she notes, adding that California and New York also have excellent track records in this regard. Now, as one of four senior green building consultants at Paladino and a registered mechanical engineer, Sweek provides technical consulting and energy modeling to guide project teams in optimizing alternative, active and passive system design and operation. “My work is focused on testing buildings and finding ways to operate them using less energy. My professional goal is to offset the carbon footprint I produce in my personal life by identifying, implementing and verifying building energy savings.” Called building commissioning, Sweek’s work brings together the technical with the practical. “I see that the owner’s operational needs are met, that building systems are optimized to perform safely and efficiently and that building operators are trained to keep it all running,” she says.
Sweek is also well-versed in sustainable program consulting and writing, as well as addressing commercial and institutional issues and constraints in relation to the LEED® Green Building Rating System. She notes that her HMC studies gave her a good start. “Mudd’s engineering and math curriculum gave me more than I need to understand building science and apply it to green buildings,” says Sweek. “The state-of-the-art computing technology introduced me to the software that I still use in my job. It also taught me how to connect with people and find information beyond my physical location. Most of all, learning and growing along with my fellow students taught me skills in teamwork and cooperation that will serve me for the rest of my life.” As an experienced project manager and consultant, Sweek has worked on one of the greenest projects in the world: Las Vegas Springs Preserve for the Las Vegas Valley Water District, which is LEED Platinum, the highest LEED rating. One of her current projects is the $52 million World War II Valor in the Pacific National Monument visitor center, which commemorates the heroic individuals involved in the Dec. 7, 1941, attack on Pearl Harbor. Paladino is the project’s sustainability consultant, with Sweek taking on the role of commissioning agent. For the last two years, Sweek has traveled to the site providing sustainable design consulting, technical assistance and commissioning,. The three-decades’-old visitor center is Hawaii’s most popular attraction; more than 1.3 million people show up annually at the facility that was designed for 750,000 visitors. The new design will allow the visitor center to expand to 24,000 square feet, doubling the current museum exhibition space. Gathering spaces are being expanded and the museum will have almost twice as much exhibit area. Sweek is excited about the sustainable features of the visitor center. “There will be a 50-kilowatt photovoltaic system which will generate about 25 percent of the building’s annual energy consumption. Also, since it is an environmentally sensitive site, we’ve minimized the water usage.” Most of the buildings will be naturally ventilated by trade winds that blow 29 out of 30 days per month. “We are taking advantage of human thermal comfort science which says even if it’s 80 degrees inside a slight breeze will keep most people as comfortable as they would be in a fully air-conditioned, 65degree room,” says Sweak. “Another great feature is thermally massive construction that is shaded right next to the walkways between buildings. The thermal mass cools down overnight and then is slow to heat up. It radiates a cooler temperature for most * Leadership in Energy and Environmental Design

of the day. This design is similar to the cooling effect you feel in the HMC quad dorms when the breeze is blowing down the corridor.” A few of the spaces—like the LAN computer servers and the security office—are air conditioned. This is a challenge in projects with multiple small buildings and spotty need for air conditioning. “Normally, spot air conditioning would use a bunch of equipment because every small room would need a matching outdoor unit,” says Sweek. “We solved this by using a ‘multizone’ refrigerant system which has a refrigerant manifold so a single outdoor unit can be matched with several indoor units.” Now that the project is nearing its end—a formal opening ceremony for the new visitor center is being planned for Dec. 7, 2010, the 69th anniversary of the Pearl Harbor attack—Sweek will be busy testing the lighting and the solar system. She will return again next summer after all systems have been operating fully to talk with building maintenance personnel about how well the systems are working. Sweek sees the new facility as a way to introduce sustainable
design to a diverse audience, especially older generations. “There are thousands of visitors everyday. To have it be a green building and attract a wide variety of generations, especially those who served during World War II, is important. They will be able to see just how practical and efficient a sustainable building can be,” she says. Consumers are taking a little longer to fully embrace the sustainability movement, in part, Sweek believes, because the information being shared at every turn is a bit overwhelming. She says that she would take a different approach and introduce concepts more slowly, with simple ways that consumers can make gradual changes. Spreading the word about sustainable structures is something Sweek is intent upon doing. The next career move for her is a focus on the existing building market, where she sees more technical challenges than in new facilities. “Corporations really get it,” she says. “If you make green engineering part of the decision-making process, it is a natural result that plans for new and existing buildings will be sustainable.” TREASA SWEEK
The renovated World War II Valor in the Pacific National Monument visitor center now boasts a 50-kilowatt photovoltaic system which generates about 25 percent of the building’s annual energy consumption.

THE PHOTOVOLTAIC
revoluti n As PV use spreads, Mark Mrohs ’74 is there to provide his expertise. Written by ELAINE REGUS Photography by SETH AFFOUMADO
Mark Mrohs ’74 conducts training at a world-class photovoltaic training facility he had built at SunPower in Richmond, Calif.
Mark Mrohs ’74 has spent his career making sure the lights stay on in some of the most remote reaches of the world. Now senior manager of global training at SunPower Corp., Mrohs began working with photovoltaics the summer of his junior year at Harvey Mudd College. He was working in the research and development department of Spectrolab, making solar cells for satellites at a time when the terrestrial market for photovoltaic (PV) power systems was just taking root. Over the years, Mrohs has worked for several of the largest PV manufacturers in the world. He’s traveled to 25 countries and trained thousands of people in the design and installation

Harvey Mudd College
SUMMER 2010
of solar power systems. Today, he is considered an international expert in technical training for photovoltaic systems. “Training is particularly important in developing countries where millions of people rely on rural electrification programs funded by organizations like the World Bank and International Monetary Fund,” Mrohs says. “Governments and NGOs can have the best intentions to fund rural electrification using solar power, but if you don’t have people on the ground who know how to install the modules or batteries, or do the wiring correctly, the systems will fail within the first year, and everyone will be discouraged.”
“PV technology is proven and becoming a mainstream commodity. It is not going to go away.” –Mark Mrohs ’74
Mrohs designed the curriculum and managed the instruction for the first national solar photovoltaic training program funded by the World Bank. The SPV Training Programme for India was overseen by the Indian Renewable Energy Development Agency (IREDA) and awarded to Siemens Solar from 1995 to 1998. Using curriculum he developed, Mrohs taught a series of three, two-week, technician training programs and a oneweek advanced design and installation program each year over a three-year period. He worked primarily with the prestigious Indian Institute of Technology at Madras (now Chennai). The university subsequently developed and still offers a photovoltaic technician training program based on the training that Mrohs provided. Hundreds of millions of people in rural India and other countries do not have access to electricity from a grid extension, so they rely on small gasoline generators, which are noisy, smoky and notoriously unreliable. Even those living in cities have standby generators because of frequent power outages. Photovoltaic systems in rural areas charge batteries which are then used for lighting, which is much safer than burning cow dung or liquid fuels, and to power TVs, radios, sewing machines, cell phones and tools. They provide power to run vaccine refrigerators in small rural clinics or to recharge batteries on remote microwave and radio repeater stations. Mrohs was awarded the 2009 ISP Mark C. Fitzgerald Memorial Award for his dedication to promoting quality renewable energy training. Under his direction, SunPower has developed a sophisticated training and certification program that has been accredited by the Interstate Renewable Energy Council (IREC). SunPower is the only PV manufacturer in the world with a training program that meets the international standards set by
the Institute for Sustainable Power Quality, established by the late Mark C. Fitzgerald, a close personal friend of Mrohs. Today, photovoltaics is a multi-billion dollar industry with major markets throughout the developed and developing worlds. As the price of solar continues to decline and the cost of conventional electricity continues to go up, the U.S. market opportunity will only get more exciting as ‘grid parity’ in cost approaches. “PV technology is proven and becoming a mainstream commodity. It is not going to go away,” Mrohs says. What makes photovoltaic technology unique is that it doesn’t inherently depend on the economies of scale that are required for conventional centralized means of electricity generation that require large generators—a single solar module is just as efficient as a big field of modules covering acres. “You can’t make a small nuclear power plant or a small steam power plant. You make them big, hundreds of megawatts, to be cost effective. With solar you can make a power plant that is just four kilowatts, just enough to power a house. That inherent nature is unique to PV,” says Mrohs. “Wind is a brethren renewable technology to solar PV, and can be scaled small or ramped up into large megawatt farms, but the solar resource is more widely distributed than the wind resource, so we have an advantage there.” Manufacturers are continuing to work on ways to make solar less expensive and more “clever,” Mrohs says. SunPower makes solar tiles that blend in with regular flat ceramic roof tiles and are being used by Southern California new home builders. And BIPV, or building-integrated photovoltaics, is gradually being adopted by architects and incorporated into the glass walls on the sides of office buildings. Mrohs is confident about the future of photovoltaics, a career that has blossomed since his days at HMC. “The HMC experience was the best time of my life, when the most doors in my mind were opening, the best friends were made, the most inspiration was given,” Mrohs says. “My confidence was given anchor there, and since then I have been out in the working world, and have held my own, not arrogant but confident that I have the problem-solving skills to overcome the challenges that keep coming.” Elaine Regus is a freelance writer based in Claremont, Calif.

Stan Love reports about a project his wife, Jancy Mcphee, is undertaking: “A project Jancy has been developing at NASA is called the Humans in Space Symposium Youth Art Competition. It is an online art competition for children aged 10-17 years old. They are invited to express what they think about the future of human space exploration via literary, visual, musical or video art, and then the winning art (and the winners) will be part of a live performance and display held at the international Humans in Space Symposium in Houston, April 2011. Human space exploration experts from all over the world, who will have gathered to plan the “Next Golden Age of Human Space Flight,” will hear/see what the youth of today have to say on this topic. The resultant dialogue is meant to allow youth the opportunity to actually influence what the plan for the future will be, since they themselves will be the generation that implements it. It is also meant to educate them, interest them in space and STEM education, and hopefully encourage their future participation in human space flight. Jancy hopes to see participation from children from all over the world.” For information, see www.humansinspaceart.org.

Brian Glen Hastings completed his first double century (200 miles) bike ride this past June, cycling in the beautiful Eastern Sierras near Bishop, Mammoth and June Lake. He had a great ride and rode far better than he expected. Glen finished 27th out of 149 riders, and completed the 196 miles (course was a bit short) in 12:50 (11:32 on the bike or 17 mph pace). In addition to being the longest distance he had ridden in a single day, he managed to set three other personal bests during the ride: highest altitude ridden, 8300'; fastest downhill speed, 54.2 mph; and fastest metric century, 100 km in ~ 2:50 or 21.9 mph

Andrew Ross received the 2009 Ronald W. Collins Distinguished Faculty Award, the highest honor a faculty member can receive, at Eastern Michigan University. The award is given to a faculty member who has taught less than five years at the university. Andrew received a plaque and a $3,500 honorarium for his innovative teaching style, in particular, for his method of teaching the Markov Chain, a discrete random process. By using a stuffed Kermit the Frog—a relatable and understandable example—he describes how the system applies to a frog hopping along one pad at a time. Andrew’s classes range from general education requirements to graduate courses, with each course focusing on making mathematics applicable to every person. He received his master’s degree and doctorate at the University of California, Berkeley, then took a postdoctoral position researching electric power grid policies. He went on to teach at Lehigh University in Bethlehem, Pa., then joined the EMU faculty in 2006. continued on page 30

ottom line: The world’s population uses a lot of energy. It’s time to seriously start thinking about alternatives. Let’s think raspberries. In order to understand this line of thinking, one must have attended chemistry Professor Hal Van Ryswyk’s Alumni Weekend presentation about Creating Your Own Solar Cell. I’ll get to the raspberries in a moment. One obvious power alternative is solar energy, which is more incident upon the earth’s surface in one hour than humankind uses in a year. Photovoltaics, a class of solar energy conversion technology producing direct-current electricity from sunlight, is an option, but currently a costly one (Read about PV pioneer Mark Mrohs ’74 on page 22.). Van Ryswyk suggests that the dye-sensitized solar cell (DSSC) is a better, more economical model. They utilize a cheap, rugged semiconductor as a lattice upon which low-cost dyes are chemisorbed. A group of about 25 alumni trekked to the chemistry lab to assemble their very own solar cell made up of three main components: a semiconductor photoanode lattice that supports the dye and provides a pathway for transport of the high-energy electrons; light-

absorbing dye that injects the high-energy electrons into the semiconductor; and the electrolyte that transports the low-energy electrons from the cathode in the back of the cell to the dye for dye regeneration. Enter the raspberries. Instead of using state-of-the-art DSSC dyes, the group used anthocyanins–nature’s sunscreen for plants–as the light-absorbing dye. This required enthusiastic mashing of raspberries, blackberries and/ or blueberries to extract the juice used on the TiO2 coating. Van Ryswyk described the event as “a typical lab for HMC chemists—ordered chaos with a lot of fun and some learning mixed in.” Participants–including Ed Fey ’70 (“big blueberry fan”), Carol Chin ’85, Kevin Swartzlander ’08, Robert Luke ’65, Laveille Voss ’85 and Greg Felton ’85–met with varying degrees of success. Van Ryswyk said, “We achieved anywhere from 300 to 400 mV of open circuit photovoltage (V_oc) and 80 to 300 microamps of short circuit photocurrent (J_sc). The better overall conversion efficiencies (sunlight to electricity) we saw were 0.15%.” It can be confidently proclaimed that a good time was had by all. Kathy French ’97 remarked, “It was fascinating, hands-on fun with a practical application.”
