R e a d M o r eThe Exponential Gains in Solar Power per Dollar
17 Mar, 2011
My post on the Moore’s Law-like exponential gains in solar power per dollar went up at Scientific American yesterday. Reprinting here with permission. The sun strikes every square meter of our planet with more than 1,360 watts of power. Half of that energy is absorbed…
R e a d M o r eSolar Prices Drop Exponentially for 30 Years
