alking with Quentin Kelly, founder and CEO of WorldWater & Solar Technologies, Inc., you can tell he is very enthusiastic about what he does. The walls of his office in Princeton are decorated with maps of third-world countries like the Philippines, with red dots for each solarpowered water pump and purifier installed. Low-rise cubicles have pictures of flowing water and green crops in Haiti, Afghanistan, Darfur, and other places. And the boardroom has a row of photos of solar-powered farms in San Diego and the San Joaquin Valley. But WorldWater didn’t come into existence to fuel agriculture. 30 Feet Between LiFe and death

1,000 gallons of water a minute rise up 300 feet to irrigate this farm in San Diego, powered by solar energy alone.

And he said, ‘The first aquifer would be at about 10 meters,’ – so that’s a little over 30 feet. And I said, ‘You’re kidding me. 100,000 people are dying, standing 30 feet over water.’” Kelly returned with the civil engineers from Princeton University and started to put together a plan. “They put me in touch with more Princeton engineers and a group of five – five of the same guys who had designed and implemented the rocket engine research for the NASA space shuttle – started working with me on my farm in Hopewell.” Inside a barn, his team worked through a dozen iterations before they developed a solution: a solar water pump magnitudes more powerful than anything before. Due to natural fluctuations in solar power due to dimming from clouds and daytime, other pumps would be forced to repeatedly come to a complete halt before starting back up again when the light was stronger. This constant cycle of hard stopping and starting would burn out most pumps within minutes. Kelly’s team’s pump was able to modulate its power, allowing pumps to go as slow or fast as possible without coming to an abrupt halt. Other pumps were stuck at around five horsepower of pumping strength. Their pump went up to 400 horsepower.

WorldWater & Solar started due to a foreign crisis. “I was in New York – frankly, at a cocktail party in Manhattan – and I met a gentleman who was from Sudan,” said Kelly. Representing then-president of Sudan Gaafar Nimeiry, the man asked Kelly to join a group of Princeton University civil engineers that were helping to clean the water in Khartoum, Sudan’s capital. After his arrival, he found more issues than purification. “I went to the outskirts of town with the director of national water resources for Sudan,” said Kelly. “There were close to 100,000 people Portable pumps and purifiers like Mobile Max enable faster response to disaster relief, water, water everywhere who had come across the desert from Ethiopia, whether the crisis is in Fukushima or Florida. and they were dying out there and they couldn’t come into Khartoum. I asked the Clean water crises are everywhere, not just overseas. After Hurricane Katrina in director, ‘Well, isn’t there anything to do?’ And he said, ‘What can we do? We 2005, WorldWater got a call from the New Jersey governor’s office – Mississippi’s don’t have diesel fuel, we don’t have diesel pumps, they’re not on the grid, there’s Governor Haley Barbour was looking for water engineers. “We not only had water nothing to be done.’ And I said, ‘What’s the ground water level where they are?’ engineers to send down…but one of our engineers had been working in the back,
