Hi EVerybody;

Seems I remember a proposal , YEARS ago. to put an active pad or some
setup when cars and trux ran over it, it would capture that energy, and,
maybe ,hydralicly? Recover enough energy to be useful? With millions of cars
passimng every day, you could capture energy. Of course the energy is
"Taken" from cars, which got it from gas, and Diseasel, to begin with.Maybe
a setup like this on a downgrade, where cars would be downshifting and
braking? Like catching ocean wave power, probably not cost effective. But
when I look out to sea and think of the power wasted in those Greyhound Bus
size waves crashing in.

Sea ya
