Maybe I haven't been lurking around here long enough, but I'm having a hard time understanding why it's necessary to put a large photo-voltaic array in outer space when for far less money we could float a pair of hydrogen filled rafts in the stratosphere over each of the earth's poles.
Not at the same time of course, but with one enjoying 6 months of 24/7 sunlight the other can be moved towards the equator and at least be on a day-night cycle.
Is chasing 100% utilization really worth the expense of putting a PV array in orbit?
What am I missing here?
