A quick trip down memory lane, and here's an archive of one of the stories I was following, back in the day: http://rexresearch.com/marks2/marks.htm. Lumeloid was broadly the same as what NovaSolix proposes -- cheap ultra-high-efficiency PV with optical rectennas -- albeit using polymers rather than carbon nanotubes. I had high hopes that these would be just around the corner in the 1990s, but alas the technology seems to have vanished into the mist. I'm curious to know why: was it a failure of the technology? Financing? Personalities? Alas its demise seems have been undocumented.
Hopefully NovaSolix will fare better; at least today there is complementary infrastructure (far better batteries, electric cars, etc.) which makes investment in any kind of solar tech much more viable than it would have been in the 1990s.
