a gigantic blunder…already showing sign of economic failure, as if those sign were not there to begin with…the most godawful clumsy idea yet

There’s another gigantic problem with the ideas of biofuel, at least those based on food crops like corn.

It takes a huge amount of energy to produce that corn.

Modern corn varieties yield tremendous harvests - an order of magnitude more per acre than their ancestors did. Part of that is due to breeding, but another part is due to the availability of fertilizer following WWII.

Fertilizer that takes a good deal of energy to make.

And those yields also depend on the application of pesticides. Pesticides are, for the most part, made pretty much directly from petroleum

Not to mention the energy required to till, plant, harvest and process everything.

Food crop based biofuels are a complete waste of time. The resources used for it are far better employed producing food.
