Philosophical Divide

Vote for the next green X-Prize - Plenty Magazine on the 3 Crazy Green Idea videos:

One entry focuses on energy efficiency and issues a challenge to communities to dramatically reduce their energy use; the most efficient community wins. A second entry burrows down a layer and encourages homes to go completely off-grid at an affordable cost. The third is technology-specific and asks for an ultracapacitor that would revolutionize electric propulsion. ... The three options span a philosophical divide. Should the entrants be engineers striving for a new, life-changing invention, or should the entrants be ordinary citizens who together find creative ways to be green? Both options have their merits.
