Heh. Yeah, I was thinking that any kind of home synthesis operation was unlikely to offer a financial payback. Hence the low aspirational cost, but you are right that figure is laughably low. Ethanol - easier to synthesize than gasoline (which is a complicated mixture of hydrocarbons). It has ~2/3 energy density of gasoline, which I do not think is horrible. I believe it is also less volatile and easier to store long-term.
