I just saw a unique new ad on tv, it showed a male runner running over a beautiful rugged terrain, in the sun, shirtless, the sun was shining down on his back and the commercial ad captions read in bold words,"SOLAR POWERED HUMAN" then the camera panned to his gym shoes, LOL.
"Solar powered" was the gym shoes commercial name I think. Anyway, this ad showed me the madison avenue advertizers etc are finally getting hip to alternative energy sources and the desireability and need for clean energy fueled bodies, temples.
