That's cool. There is a large market for turning heat from things like ovens back into usable electricity, using this for geothermal could be a great possibility, scalable to the size necessary. Not sure how a battery like this packages but it sounds cool. I haven't seen any progress with peltier or cool chip type inventions, this could be promising.
