Reply #36: is this guy sponsored by the nuclear or oil industries?

I might swallow the claims for ethanol; to distil it you would need high energy input although you might be able to used waste/reclaimed heat from another process, a communual heating system perhaps.

But the claim about biodiesel makes my spider sense tingle. Biodiesel can, for instance, be obtained from waste oil from fast food joints, in other words, oil that has already been extracted and utilised for other purposes. This would effectively reduce the energy extraction cost. I suspect that the good professor doesn't think like a genuine tree-hugger. Recycling reduces total energy cost.

Remember the tobacco industry whacko's told us that cigarettes are not fattening, calm the nerves and keep colds at bay.
