Re: Sums

I mentioned earlier, it's really about total surface area if you focus the energy with a parabolic reflector. So the idea is, that if the sun puts out a certain energy, and the moon's reflection is a fraction of that energy, then the ratio of the surface area of the mirror to that of the illuminated zone is roughly the same as the ratio of the moon's total luminocity (as seen on earth) to that of the sun.

It's still implying a ginormous mirror, something made of mylar would still be uncontrollable without supports, yotta yotta and the weight goes up from there. Even memory-metal wouldn't help at that point.
