So, what's the point in having so much waste heat? Unless there were some heat-recovery setup, it sounds like a scam...

Why do you need a heat recovery process? Just like in a car engine that uses a radiator to dump heat, the Suncell design is to do the same. The commercially available CPV cells are already designed with heat rejection in their design because these solar farms that use them have the same problem with heat.

Heat recovery might be quite hard to fit into a mobile application such as a car, but it makes sense in stationary applications such as a powerplant since they're less weight-sensitive.

I never made it through the 2 hour explanation; so I'm speculating; but if the reaction chamber is under a vacuum, the high temperatures may not result in large transfers of heat.

They cant prove that it works and only need a lot of money to build a working one.
What could possibly go wrong?

Unlike sound, heat can be transmitted through vacuum.

It's also illogical to throw away 60% of your output, when you could e.g. put a water jacket around it, convert the water to steam, and use that to drive a turbine & generator. But that's boringly uncool, so I suppose it doesn't attract suckers investors :-)
