You get far more energy out than you put in with diesel. Not so with
hydrogen, alcohol or methane.




I have high hopes for biodiesel too. I hope that it can at least keep
mechanized farming intact to some degree.

But even that level of usage will require a reduction in population as
an excess biodiesel will mean cutting the food supply.

We've spent 40 years in the US, paving our best farmland and building
suburbs on it. And we've used salt fertilizers to destroy the topsoil.
This situation is going to take a century or so to reverse. But at least
times will be exciting.

I agree. I think my next vehicle is going to have a turbo diesel. They
get tremendous mileage and with a turbo, have plenty of power. A lot of
people have set up biodiesel stills and get their fuel for free (waste
cooking oil from restaurants). All the auto companies have to do is focus
on getting auto diesels cleaner burning and quieter (I sure do hate those
Dodge trucks with the noisy, clattering engines) and maybe more reliable
(remember that old Oldsmobile engine that was basically a converted
gasoline engine? - they didn't last too long).

If by "free", you mean $0.50-0.80 per gallon depending on the price of
methanol and the cost of your heat source, I agree with you. The materials
needed to make the methoxide catalyst aren't as cheap as used cooking oil.

For a look at biodiesel from the viewpoint of the activist homebrewers:

There's no inherent durability problem with diesels, my 1979 Mercedes has
about 300,000mi on it and the engine's in much better shape than the rest
of the car. GM did indeed market some defective diesels when gas prices
were pushing above $1US per gallon for the first time.

Mitch.
