First of all, nothing shown in either video addresses thermal management. You concentrate light 10,000 time and you will lose that 35% efficiency gain in a hurry. In fact, you'll cook the photovoltaic cells.

It makes a hell of a solar cooker.

I'll give it that much!

And it's pretty.

could be integrated into building design along with solar panels.

it seems that on his facebook page they have worked out not cooking the solar cell in it.
We shall see.

Trying to figure out how condo association can use this...

It looks nice.

However, be mindful ( many solar proponents aren't ) of the fact that concentrating sunlight doesn't get you more energy. It just puts the same amount in a smaller spot.

You can't "make" energy.

When you played with a magnifying glass as a kid, you got a very hot spot. However, did you notice that the hot spot was surrounded by a shadow? That's where the energy that got concentrated into the spot would have gone.

So concentrators don't make additional energy, they just concentrate the energy there is into a smaller area.

I know that is really basic; but I've run across solar proponents that think that concentrating the sunlight actually gives you more energy overall, which it doesn't.

One could thus afford more costly modules and bring more light to them.

I saw a CPV tracking array at the airport in Mojave aka "Mojave Air and Space Port".

These were made by a company called Greenvolts, now out of business:

There are still some viable CPV companies.

Below is a picture of some Greenvolts trackers. Note the heat sinks on backside.

...in blending intriguing form with function. That's the goal of the design as I understand it. When there is a high value assigned to pulling the eye and mind into questioning the purpose of an object, it might not seem rational if evaluated by the traditional view of optimal cost benefit determined performance.

I like it just because.

And it's fascinating to read people's comments on their facebook page and elsewhere.

They're ready to throw money at the project and invest, yet none of it is worked out and, really, the claims defy science.

Where's the thermal management? What does this thing weigh? And, of course, the claims are incredible.

The specs don't even make sense:

This has been rehashed multiple times here on E/E, and while the idea of concentrating solar energy is nothing new, the idea you could get any kind of appreciable energy from MOONLIGHT is absurd.
