The First International Assessment of Space Solar Power
"Economically viable Solar Power Satellites appear achievable during the next 1-3 decades."

272 page 50 MB pdf report: http://iaaweb.org/iaa/Studies/sg311_finalreport_solarpo...

I posted the 90-minute press conference in the video forum: http://www.democraticunderground.com/discuss/duboard.ph...

The press conference is worth watching, especially the Q&A session which included some things not in the report.

1. By which time we'll be building 2 GW Polywell fusion reactors.
Space-based solar power is not a viable solution to ground-based energy needs. The cost to launch anything approaching enough panels is insane, combined with the logistical difficulties of bringing it home.

3. I've been hearing that line about fusion for three decades...
"We don't need to develop solar power from space because cheap, clean, unlimited energy from fusion is just around the corner." Fact: The people involved in the government fusion program were one of the groups lobbying against space solar power (SSP) when the NASA/DOE report was released in 1979. The big fusion programs are still decades away from even a pilot plant level program.

And, yes I know about polywell fusion; but, has yet to be tested on a pilot plant level program.

Even if it works, there's still the question of how economical it really is. That "cheap, clean, unlimited energy" litany has been repeated many times; it has yet to be proven.

Even if fusion - in some form can be an economical energy source, it's to the advantage of energy consumers to have two energy source competing against each other; actually, it would be better to have several forms of solar energy - and possibly fusion - competing.

2. I've been following this since the 80s
They've come a long way and could provide energy answers for the future.

4. There's another NSS video on the advantages of Space Solar Power
Space Solar Power: Advantages of Space Solar Power - Darel Preble. This presentation focuses more on the environmental of space solar power vs. fossils or biofuels.
