Yet another iteration of the soundly discredited "hydrogen economy" model. I'm really surprised this came out of Stanford, of all places. >They found that even materials such as platinum and the rare earth metals, the most obvious potential supply bottlenecks, are available in sufficient amounts. And >recycling could effectively extend the supply. >For solar cells there are different materials, but there are so many choices that if one becomes short, you can switch," Cornucopian hand waving. It reminds me of Julian Simon and his assertion that if we ever run out of Copper, we'll find a way to just make it or substitute something else for it. I'm really, really curious how they came up with their numbers on that. I'm also very interested to see if they accounted for the quantum limitations on solar cell efficiency. I think i'm going to have to actually read the paper.
