900 kilowatts?

et — 5/16/2004 9:39:00 PM (archived)

I have a little question. If sunlight at 1 AU has a power density of ~1.4 kW/m2, and you have a lens of less than a meter area, then
how do you get a 600 fold increase in power? Did you mean 900 watts?

        Not all calamities, but much food for thought. - Nick Hoffman - 5/18/2004 12:13:02 PM
