Andy and were talking about this very thing when he was here. Seems the Japanese think the way I do. Never thought of piezo crystals, though, must be a technological blind spot in my psyche.

Post a Comment- Large quantities of heavy things pushing really hard on the ground to generate electricity. Traffic! Highways! Truckosaurs! Most of the highway warning signs ("Constriction ahead. Expect decay. Use alternative roots.") are powered by solar cells on an overhead panel. Now incorporate piezo layers between pavement to light up when 80-foot loads of imported consumer goods roll over them. I foresee a new type of tax - an energy tax. Push through a turnstile, walk on a springy floor, blow into the little machine that the nice officer holds. Not only will it generate power, but will force us to exercise more. The Department of Energy will be announcing the "From Adipose to Amperes" campaign any day now. Generators on shopping cart wheels! On door hinges! In your bedsprings!
