Taking this track would involve someone with a different set of skills from
the CEO/management team I have been looking for to tackle a full-scale
gasifier project.. I am not suitable to go after a DARPA grant any more
than I am to lead a huge business. Among other factors, I have no
credibility. So the first order of business might be to recruit someone
with those skills. You have more experience in that area than I do. Any
ideas?

That might overlap with raising a small amount of money to do a video and
incorporating SolarSyngas. With modern tools like GoFundMe or Kickstarter,
that might or might not be within what I could do. I wrote the script and
produced a video, "Beamed Energy Bootstrapping," just before I gave up on
power satellites. And I wrote the fundraising letter that brought in about
$60k from the L5 Society membership for the opposition to the Moon Treaty.
I still remember the pain in my hand from signing 600 thank-you letters.

That was both a long, long time ago and a very different situation where I
had a good pitch to a group of highly motivated people. This is different.
I have no connection to any of the groups that might be interested in a
project like this. Again, ideas are welcome.
