Re: [Phys-l] [ncnaapt] another crackpot idea from theCalifornia legislative assembly



More expensive, while a problem, shouldn't really be a deal breaker. Pretty
much everything is more expensive than gas.

I'm all about taxing the children though!

Not only does it deprive the world fud (perhaps a good idea, except, tho I
send money to ZPG, it's difficult for me to suggest starving people for that
result), but also it's more costly than gasoline (at the present supply) to
grow corn for the gasahol.

bc thinks children, after one, should be taxed.

Sure, you can put down hundreds of km worth of piezos on various

still have to capture the energy, shuttle it to a useful collection

it), and then do something with it. Suppose they got 2000 W-hr over
the course
of a day (big assumption on my part). Scaling it to hundreds of km
of roads
gives perhaps 70 GJ, which is about how much a SINGLE typical
automobile used
per year in the year 2000. That's assuming 100% efficiency at every
step, the
ability to feed it all into the energy grid, and whatever other
generous
assumptions I've made.
