Currently, humanity needs about 1/10000th of entire Earth (that is surface,
not orbit) insolation. In contrast, we're tapping one third to one half of
Earth entire photosynthetic resources, which is certainly not sustainable.
Eugen's being a little blunter, and possibly clearer. This was the
same point I was making with the crack about the solar constant.
