interesting that Musk does not support space based solar. I think the case
for space based as more cost effective than terrestrial plus storage is far
from "closing"... (there are a lot of roofs begging for solar...) but if
someone actually steps forward and wants to pony up the -cash- for lifts to
space, I bet SpaceX would accept the work. It is just not viewed as very
likely, and not part of the business plan...
