Re: What-if 0017: Green cows

corrected Indeed, not as much speculation as I was hoping for. Specifically about the fins, they'll have to have a sunlit surface of 48 square metres as per Randall's calculation. I guess with radiator-style folding we can get a reasonably good volume to exposed surface ratio but these are still goi...

What-If 0017: "Green cows"

http://what-if.xkcd.com/17/ To optimize exposure, cows will need to lie on their belies with their legs spread... that's going to be kind of funny. Or maybe on their backs?
