[ExI] Power sats again

[Keith Henson]

Gave an hour talk at Google today on the new breakthroughs that have
reduced the startup cost to $60 B, the time to first power sat on line
to ~7 years and raised the ten year ROI to 500%.  It also has the
potential to keep the CO2 somewhat below 450 ppm.

Was well received.

I can send a draft of the article the talk was based on if anyone is interested.
