Thermoelectric effect based energy generation

Today morning I was investigating the Seeback effect, as a means to convert heat differentials into electricity (sound familiar? The stirling engine! except, no moving parts, no expensive bits and pieces, and no large heavy engine)

Well, after a bit of snooping around, this man has already tried this. But there's no mention of the efficiency etc. Of course, since he thought of it first, he's already give it his name.

Of course, it's a little more complicated than just applying a heat difference between two pieces of metal. And it's actually very interesting, with theoretical efficiencies being as high as 60%. It's still going on, hope we can get more updates soon.
