Not to mention that disposing of Prius batteries, after their

Some claim making the Prius battery is an even bigger problem:

That is amazing. Thanks for that input.

Same, but different, argument about bio fuels. The NET energy is
negative in some cases.

Not to mention driving up the cost of food in countries dependent on
corn...

There aren't that many--rice and wheat are the major grains for most
of the world--corn as table food as opposed to livestock fodder is
largely an American (north and south) phenomenon--poor silly furriners
don't know what's good.

But you can also get alcohol from potatoes, wheat, beets, sugar cane,
and many other plants, basically anything with enough sugar to support
fermentation.

All thinking small though--the high tech approach would be a
bioengineered tree that one taps to get diesel directly--one suspects
that such a thing could be bioengineered once biotech matures a bit
more. But talk about forest fires . . .
