That is awesome. i didn't completely understand how the wood-conversion process works because my head was/is spinning.
i think the problem(s) is not with the cars/trucks, but with the engines. Or more specifically, the fuel; Gasoline in and of itself is not so much the problem---there is plenty of it. But because demand is high, the price will be high.
i still feel my vision of high-compression and water injection is probably the best overall short-term solution, in general, for most people maybe.
