This stupid idea gets floated every few years. It doesn't work, even in theory. Do the math yourself.

I just took a look at that site, and while in general I agree with his conclusions, I am perplexed by some of the math that he uses.
For example I do not see why Tg is different for ground based versus space based systems, and why it so not eliminated as per the E term (and why is Tg higher for a space based system?). And the links he supplied for the lifetime of space based cells are frankly puzzling to me as I cannot see anything in them that backs up his assertions (which is different from saying his assertions are false).
In addition while a space based system has issues with transmission and degradation, he leaves out the fact that a space based PV system operates 24/7 with continuous output compared to an earth based system that has to deal with the vagaries of weather and that pesky thing called "night". Thus an Earth based PV system will always have to have additional non-PV infrastructure in order to deliver comparable energy delivery. So that will also change the overall economics.
