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.
