Is that Alan Alda doing the talking?

the icelandic guy says "actually" probably more than 20 times in this short video

Definitely Alan Alda.

Alan Alda?

this is an old video cause they already have all their city buses running on hydrogen and have hydrogen stations running... too bad how rich the USA is that the politicians are bought off we could change over in less than a year if we really wanted to

"the new world order" is responsible.they wont let us have the cheap energy.learn about the "new world order" for F@#K sakes.

The documentary is called Scientific American Frontiers. You can stream the episode "Hydrogen Hopes" from the PBS website. However I must make a correction after watching it again. The hydrogen stations aren't powered by solar, my bad. I must have got up to get a drink during the transition ;). Not a bad idea though.

The real problem with vehicles like the BMW is that they must rely on the carnot cycle. They are inherently inefficient. Electric motors are much more efficient than internal combustion engines. Also, batteries are quite efficient. Why not go with electric cars. Hydrogen is really not that efficient for many reasons.Electrolysis is horribly inefficient. It yields a lot of heat to separate hydrogen and oxygen from water. Fuel cells are much more promising. However, they are vy expensive

"For a nascent market like hydrogen, further segmentation may be its death blow"Perhaps dual-fuel vehicles, like BMW are pursuing, are the way to go, to facilitate the roll-out of the network, and transition to a hydrogen system."My bad, it's actually CH4 + H2O = 3H2 + CO. The carbon monoxide gets released into the atmosphere. The reaction creates heat which is also just heating the atmosphere"Electrolyzing H2 from water using electricity from renewables, as per Iceland, seems the go then
