Since Sliced Bread: $100,000 winner sounds familiar!
The winner of the $100,000 SinceSlicedBread competition recommended developing a fund to help us overcome dependence on foreign oil. "Promoting sustainable localized energy industries (solar, wind, hydro, tidal, biofuels) will provide reliable, clean homegrown energy, exportable technologies, and bring energy jobs home." Sound familiar?
However, it also has a "save our way to prosperity" feel to it. It seems less of a market (read "business") focus - which I feel is an essential component in moving forward. That is - leverage (encourage?) what is great about our capitalist, free-market system to help us solve this grand challenge.
