Power Walking Innovation Climate Victory Gardens

A basic law of physics states that energy cannot be created or destroyed. Kinetic energy pushes us forward each time we take a step. According to the Mayo Clinic, the average American takes 3,000 to 4,000 steps a day, with many aiming for 10,000 or more. That’s a great deal of energy that gets transferred to the ground unused.

As a design and technology student in London, Laurence Kemball-Cook devised a plan to collect the secondhand energy of footsteps and store it in a usable format. In 2009, a kinetic floor tile that could generate clean electricity was born. Today, Kemball-Cook is CEO of Pavegen, one of many companies looking for ways to advance sustainable energy. Pavegen has installed more than 200 projects in 37 countries.

Pavegen’s sidewalks are made of tile-like triangular platforms. When someone steps on a tile, a flywheel is activated to spin extremely fast, generating power that is sent to and stored in a battery. Although these smart sidewalks do not have the capacity to power entire cities, they can provide energy to office spaces, shopping malls, neighborhoods with streetlamps, sports games and music festivals. While the company works to lower costs and extend their application, Pavegen has been using its energy-producing sidewalks as an educational tool for sustainability awareness.

During World War II, an estimated 20 million Americans planted individual and community “victory gardens” to assist the war efforts by producing more than 40 percent of the fresh fruits and vegetables consumed in the country at the time. As the world faces a different kind of threat today, Green America is encouraging and training people to plant “climate victory gardens” to restore soil health and draw down carbon as a way to help solve the climate crisis.

The project invites people to log their garden on an online map (GreenAmerica.org/climate-victory-gardens), showing the cumulative impact of their effort. More than 20,000 climate victory gardens have already been planted, collectively sequestering approximately 4,740 tons of carbon per year, which is equivalent to eliminating the emissions from driving more than 39 million miles.

The mission of Green America, a nonprofit, is to mobilize and empower consumers, investors, businesses and the marketplace to create a socially just and environmentally sustainable society. Green America provides information on regenerative gardening in down-to-earth terms for beginners and seasoned pros. They also provide resources on related topics, such as organic fertilizers and pesticides, raising chickens, growing food indoors, composting, supporting pollinators and building a rain barrel.

Maximizing Lutein in Green Smoothies

Research indicates that lutein is essential for eye health, suppresses inflammation and offers cardiovascular health benefits. Because the human body cannot make this powerful antioxidant, it is important to include it in the diet by eating dark, leafy vegetables, such as spinach and kale.

A new study in the journal Nutrients has found that coconut milk is the most effective plant-based milk to liberate lutein from spinach in green smoothies. The scientists from Linköping University, in Sweden, tested 14 liquids, and only four increased lutein liberation in spinach smoothies. Compared to blending spinach with water alone, coconut milk without additives was found to improve lutein liberation by 42 percent. Improved lutein liberation was also found with high-fat cow’s milk (36 percent), medium-fat cow’s milk (30 percent) and coconut milk with additives (25 percent). Researchers noted that soy milk with and without additives actually reduced lutein liberation by 40 percent and 61 percent, respectively.
