The heat is actually from the cooling system that is in the reciever head.  The efficiency of the solar cells is increased with cooling.  These particular cells I believe operate at a higher temperature than the normal cells that are currently available. So even with cooling the waste heat cooling fluid is at a high enough temperature to be used for some process heat and it is more than enough for heating dwellings.

I would think that if you wanted more efficiency in the production of electricity with this gadget that you would want less heat since there efficiency degrade with the amount of heat? Unless you needed more hot water than electricity?

Where and how do they harvest the heat?

This is not a scam unless the University of Arizona Roger Angel project, which is essentially the same, is a scam. The mount structures are different with the Zenith Solar looking much better in my opinion.  The optics are probably different as the UA system uses a spherical lens for the final focus (the Zenith optics are not shown).  The high "efficiency" is from using a combined photoelectric (a very advanced and expensive multi-spectrum cell) and a thermal system (just for heat). The UA system quotes similar numbers.  If the reeiver is designed properly it doesn't have the high losses you are concerned with although that design must be tested to see if it actually achieves the stated efficiencies. The opening apparature to the receiver has to be as small as possible.

I hope it's not a scam.  I feel suspicious, but then I usually do.  It seems to me that the small gadget that is at the focus of the mirror will glow white hot and radiate away most of the energy.
