Today in the O.C. Register here in So. Cal, I found TWO big ads:

Ostensibly, one would think they were for new model cars. Then I noticed one was non existent. The Volt concept. “Wow†I thought, they’re advertising nothing. So is that just for ‘Green’ P.R. ??
A couple pages later I found the second GM ad, for a hydrogen car that will be delivered to NY, Washington and L.A. as fleet vehicles. The ad says they reduce our dependence on petroleum? Where do they think the hydrogen comes from? Isn’t most hydrogen supposed to come from electricity, created mostly via natural gas, and coal? Creating hydrogen from electricity takes a TON of power from ‘somewhere’. Here are the rough “apples to apples†calc’s I came across:
1. Electricity to hydrogen via electrolysis to fuel cell (not counting compression energy) to propel a car uses four times the energy as electricity to battery electric vehicle to propel the car.
2. The electricity to compress hydrogen to liquid form (how hydrogen is transported to fueling stations) uses so much electricity that this amount of electricity would propel a battery electric vehicle (without using the hydrogen) about the same distance that the hydrogen would propel a fuel cell car.
Then there’s the thing about hydrogen cars STILL costing about a million bucks. So regarding these ads, doesn’t that beg the question, “Hey, Gm, what are you saying?â€
