Exactly! The reason why hydrogen is inefficient is because the energy must move from wire to gas to wire in order to power a car. Upon the conversion of hydrogen to electricity, you're looking at a 38% efficiency rate. Not good at all.I would hazard that the easier money is on the other side of the business...producing the things you need to turn hydrogen to energy. Two problems...
1- There isn't enough of it
2- Production and supply is a giant pain in the arse
I'm more into passive forms of commerce.
