Lonnie Johnson: Awake to the Possible 4/6

"The sun is the singular energy source that can supply all the future energy needs of the world in a sustainable way. The challenge is how do you get the energy from the sun into a useful form at a cost that's practical."

If inventor Lonnie Johnson is right, next generation energy generation and storage technology will revitalize the American economy, put millions of people to work, reduce the need (and cost) of foreign military adventures, impair the power of several semi-hostile nations, lessen pollution, enhance public health and curtail global climate change. Not bad for a guy who made his first fortune by inventing the Super Soaker water gun. Reputable scientists believe that he is right both about the future and his role in it.
