Slightly off topic, not Solar but Thermal
Rick... (The other Rick)
The Russians seem to have developed Thermal generators in the past
See

and
http://www.bellona.no/bellona.org/english_import_area/international/russia/navy/northern_fleet/incidents/31767
Now I have no desire to have such a device anywhere near me.
These people seen to have taken the idea a bit further
http://www.triz-journal.com/archives/1997/01/a/index.htm
and a commercial device is available
http://www.hi-z.com/hz20.php but is a tad expensive.
Anybody know of a source of plans for home made a thermopile or even if it's feasible?

All Peltier Devices work in reverse, ie if you provide a temperature
differential across the device, then it will generate electricity.
No one seems to be however making such devices specifically for this
market, mainly for the reverse, ie thermoelectric coolers.
The modules arnt all that expensive.
I made a small fridge using 2 X 60 watt modules.
They cost $18 each.
The problem when using them to make electricity is how to get the heat
away from the cold side fast enuf.
Simple air cooling with a big heatsink isnt normally good enuf.
You need something like water cooling and a heat pipe.

Are you aware of any kind of work/ research going on
in this area ie reverse refrigerators.

No.
The problem is the design of the modules themselves.
They are very small.
The ones I used were only 4CM x 4CM which is too small to get
a decent sized heatsink onto the hot side.
You need a better design with a larger contact area on the hot side.
