I can’t imagine MAGAts paying a subscription to any print news media, so it will be interesting to see whether Bezos will simply fund a propaganda rag, or turn it into a soft porn maga manga to make it profitable.

Joseph: the situation in CA is different, due to electricity costs (in PG&E areas at least). At ~ $3.50/gal my Prius (~45-50MPG) does about 7c/mile in fuel. Chevy Bolt is slightly worse - averaging 4-4.5miles / KWH and a price of over 40c/ KWH at home (best case. It can easily be 60c).

Actually I think all H2 fuel cell cars use a battery like a conventional hybrid system does, for acceleration assistance and regen braking - improving overall efficiency. Any EV is more efficient than an ICE and a much better fit to power/torque requirements for transportation anyway.

Are you assuming hydrogen is used as a fuel in a combustion engine or through a FC? A fuel cell H2 system really is just another eV, although I agree that it’s not currently cost effective to use green H2.
