[Server-sky] Server Sky transport energy comparison

Launch costs a heck of a lot more per kilogram than ship/rail/truck,
but server-sky thinsats produce a heck of a lot more energy per
kilogram than a terrestrial solar panel.  The transport energy
payback time for a Chinese solar panel sent to the New Mexico
desert is 60 days, for a first generation thinsat is 22 days. 

Second generation ultralight thinsats, ballasted with harvested
space debris, may have transport energy payback times of less
than five days.

Third generation thinsats, manufactured in space from lunar
materials (chips and rare materials still earth launched)
will be cheaper still, but my crystal ball is too cloudy
for usable estimates that far in the future.
