It is an interesting concept.
Money can be made if you can mass produce cheaply and sell to the consumer at an affordable rate. That has always been the problem with solar.
Basically a more efficient, cheaper version of a solar panel that you can stick on your window to block out radiant heat in the summer, keep in radiant heat in the winter, while at the same time capturing energy for your house in something that can be applied by hand easily in existing structures or in new structures something that can be built into new windows.
The night vision has great military purposes if you can see further more clearly, but also if you make it cheap enough a haji in the middle east now has the capability to see at night as well :/
If they can bring it to market that would be amazing, but I bet that it costs to much to produce at this point.

That proposed system is full of fail and AIDS. The flux of IR photons in sunlight is high, but their energy is low, and thus IR photovoltaic devices have shitty power conversion efficiencies. With all the talk of carbon, it's safe to assume those are also organic PVs. The main problem with them is the high exciton binding energy, which eats up even more ( more than half!) of the available energy of IR photons. These devices are also not now, nor will they ever be "free." And then he starts talking about beaming the energy around with light?
Yes, lets add more inefficiency to our power collection system.
Anti-IR coatings and electrochromic windows are already available.
There's lots of cool tech to come from nanotechnology, but this guy is a rambling huckster.
