It's refreshing to see new energy ideas, even if it’s just in conceptual phase. I'm sick of hearing about bio-fuel, solar, and wind power. These technologies have been in development for decades now with only meager breakthroughs into society. (yes I know that political hurdles are part of the problem)
Sound as energy has so many applications in America; just consider the amount of noise pollution just in one city. These guys better get funding.
