Nice PR, but how much impact ? (Score 1)

IBM probably processes less than 100,000 wafers, mixed 200mm and 300mm, a month. If they are yielding 80% to devices that is 20,000 wafers a month available for solar applications. And this is a very aggressive estimate. It isn't a lot compared to the needs of the photovoltaic people, who now by more silicon that the semiconductor companies.

But recycling is good, I guess, given the cost of making silicon in the first place.
