They are going for the old "We are saving the world, back us now, it's not thermodynamically impossible, and we'll reveal the data to backers once we get the money" trick.
Dave, you only busted this gadget for the case that they use Peltier cooling, as this kind of heat pump got a COP of around 1 or less only.
Although their proto design pictures indicate the usage of Peltier elements, they state, that these pictures do not reflect their actual solution..
What Stebanoid and me were saying, that due to general Thermodynamic Laws, this product can not work at all with these form factors (of solar panel and cooler).. in other words, their claims indirectly violate the laws of physics, similar to all these Perpetuum Mobile and "Free Energy" freaks.
To make this gadget work in this form factor , they would have to develop an extremely efficient and compact refrigerator, comprised of a near perfect Carnot heat pump:
https://en.wikipedia.org/wiki/Heat_pump, COP >= 30, and very efficient condenser and heat exchanger.
That all would require many mechanical problems to be solved, instead of electrical ones.
Such a heat pump has to be made of a miniaturized vapour-compression machine.. but a practical exemplar can achieve COP ~ 7..8 under these circumstances only.. and I really doubt they'd be capable of developing such a miniaturized machine.
The efficiency of heat exchanger, condenser and solar panel further reduce this COP factor, so their claims fall short by an order of magnitude, at least, but in a more fundamental way.
