In 1996 I wrote in these newsgroups about an idea I had worked out
about using thin film reflectors inflated on orbit to concentrate
sunlight onto a solar pumped laser. That laser beam would be beamed
to receivers on the ground which would convert the power to
electricity and thermal energy for industrial use. Overall efficiency
would be 40%

I was roundly attacked by all - and so, it was with great interest
that I read the following on yahoo news service in 2007;

I am fully justified in my earlier statements - and all those who
mercilessly attacked me have been proved dead wrong in their negative
assessments of my ideas.

But that's exactly what this mostly Yiddish anti-think-tank of a
Usenet from naysay hell is good at doing, is their topic/author
stalking and bashing with everything they can muster. (I believe it's
one of their born again faith-based things that's pretty much naysay
to anything off-world, especially naysay if you're not a fellow Yid)

I happen to agree that an interactive and thus fully controlled set of
laser cannon beams from space to multiple terrestrial receiving
stations is perfectly doable, especially if tether deployed away from
the LSE-CM/ISS that's parked in the moon's L1 would get those fully
solar illuminated SBLs situated as close to Earth as you'd like, or
dare, along with the tether dipole itself offering teraWatts of energy
to spare.

Your 40% overall energy transfer efficiency wasn't even all that far
off. Even a solar farm of reflectors merely giving a focused narrow
beam of the full solar spectrum isn't all that insurmountable,
although a solar pumped tight laser beam of mostly IR is perhaps best
suited for the task, whereas system robotics would avoid most any
unfortunate encounters with items not suited for surviving such beams
of raw energy.

Space Laser to Transmit Solar Power to Earth, By Hank Green (why the
hell not?)

I bet Willie Moo could do this rather nicely, starting off small and
growing along with the required expertise for making it happen in a
very big and clean enery way.
