Diesel will never have the political (and therefore media/pop culture) support of electricity. One large reason is the fact that we can come up with biofuels without political/corporate infrastructure meaning they can't control it and exploit it the same as the coalfire generated electricity and gasoline almost every hybrid scam machine runs on. If anyone in the political/corporate world was ever sincere about electricity, then WTF happened to the EV1? I can't wait till I move to a state that'll allow me to drop a Cummins in my RC.
