The UV waterworks device provides developing countries around the world with an energy efficient, affordable and fast method to disinfect hazardous contaminated water.

Through the use of beams of ultraviolet light, a Berkeley scientist has developed a cost and energy efficient method to clean polluted water in developing countries, and the success of his work has landed him a role in a soon-to-be-released film.

Since completing his doctorate work at UC Berkeley, Lawrence Berkeley National Laboratory environmental physicist Ashok Gadgil has devoted his research to energy efficiency. His success in developing a system to provide clean water to billions of people around the world has made him one of seven scientists featured in the upcoming movie "Me and Isaac Newton."

Gadgil is a scientist in the Environmental Energy Technologies Division and invented UV Waterworks ? a battery-powered water purification device that has been used widely in developing countries where a lack of clean water has posed dire health problems to people. His machine has also been credited to saving lives in the aftermath of natural disasters such as devastating hurricanes.

I strongly encourage those seriously interested in learning about the technology, players, politics, and issues of Wind Energy to spend time browsing the American Wind Energy Association website. They are the premier industry trade organization and have extensive resources available.

Why I Publish This Blog:

"One thing that many people do not realize is that states like Wisconsin, Illinois, Indiana,
and Michigan are sitting on a gold mine of wind energy potential. Or, more properly, next to the mine.
The Great Lakes are probably the area in the USA with the third largest inland wind energy potential.
Think of just the nickname for Chicago. "The Windy City". Milwaukee is even windier, I can tell you.
Why? Because they sit on the edge of a great flat area where there is both a land-water temperature
differential, and a large flat expanse of water that is comparably shallow.
Oilrigs certainly operate in deeper waters. And you won't have to construct transmission lines all the
way from the plains of Montana to put it to use.

The Great Lakes area has an opportunity to get the jump on wind energy's future, if that fact is
recognized and exploited. Wind energy means jobs for construction and maintenance workers, thousands
of them. Wind energy means leasing rights and extra money for family farmers struggling to make it on
agriculture alone. In most cases farmers can grow crops right up to the base of a windmill. The land
footprint has a small impact on total farm acreage. Wind energy also means freedom from fluctuating
fuel prices. Wind is free. The cost of a barrel of polluting oil can be raised or lowered drastically
based on fears or political whims. The potential gains are enormous. We've all seen the flow of good
manufacturing jobs out of the area. Well, they can't tell the wind to blow in another country so it's
more "convenient" or cheaper to produce. The wind is perfectly happy to whip up opportunities for us
right around here. Most of all, because we here in the Great Lakes region have the potential to have
a huge positive impact on U.S. energy industry emissions' contribution to global warming."
