Renewable Energy Investment Prize

Invest Renewable X PRIZE - The Renewable Energy Initiative - This is one of the entries in the "Crazy Green Idea" X PRIZE contest. The proposal is to reward $10M to the first group to invest $10B (e.g., in retirement plans) in renewable energy. I don't know how well the general idea would work in the business or legal world, but as often happens I wonder how it would work for the space industry.
