oh yeah. we're essentially burning food-grade fuel. i'm sure it has
adm laughing all the way to the bank.
cellulosic ethanol will be the saviour, if and when it ever becomes

" Why not?
rust.
" The biggest reason cited for vehicle replacement is drivetrain failure.
nationwide, or just in the rust belt?

" They should be more efficient, but there is a lot of transmission and
" charging loss in the equation for large numbers of electric cars.
that's true. i've heard that transmission loss is as much as 50%, and
that gas pipelines transmit power more efficiently than power lines.
" We are also near peak power in many areas.
not around the clock. cars could be recharged only in off-peak times.
