A very neat idea, and it is an important feedback we should try to keep 
under control. Of course millions of devices costing between ten and a 
hundred bucks each will be a rather expensive project. Not to mention 
the problem of them drifting south and the damage done when they 
occasionally break.

I wonder if these diodes could be used to boost glacier water storage. 
That is in many ways more important than floating ice, since much of the 
world relies on glacier-originating water.

What is the temperature differentials they can maintain?
