AmericanInKiev writes "Computer World posted a piece on Al Gore and his claim that solar cells will improve at the same rate as microprocessors. Vinod Khosla on the other hand has expressed disappointment that the doubling rate for price/performance of PV is 10 years rather than 18 months for transistors. Which of these two has the facts on their side?"
Before anyone has him inventing the Internet again, note that Gore's claim as related in the article is much milder than that Moore's Law applies to solar cells per se -- namely, he's quoted as saying "We're now beginning to see the same kind of sharp cost reductions as the demand grows for solar cells." An optimistic statement, but not a flat-out silly one.
