The 8008 1783

The crops for making biodiesel is closer to tending a forest than clbuttic farming. This is not foodcrops, it is a fast growing forest.

Neither do I; and I don't get what is so special about Hydrogen; except that it is the sort of atom that is the most common building block for animals, humans included.

It is all about price. At the current $70-barrel these things start to make a profit; mostly wind and the largest solar and tide projects. At $200 farmed diesel is profitable by a far margin.

$70-barrel translates to a US pump price of ~$4, $200 to a pump price of ~$11. This as a reference to how bad it can get.

A correctly burning diesel engine gives almost no fumes. The minuscule carbon flakes that is the signature of a bad diesel or bad fuel is another matter.

Diesel microbes. Used to be rare, now more common. Makes a sticky mess of the diesel surface, and is almost impossible to clean out once you got it. Makes a lot of black smoke in larger diesels, and stops the smaller ones.

Biodiesel can go below $10-gallon if they can base it on some recycled input; approx $13 it they have to start from scratch.

The eco-weenies will stop dead in their tracks once pump prices start to skyrocket. Either that, or they will be lynched by an angry mob.
