current thermoelectric devices have a low ratio of thermal to electrical
resistance, on the order of 1:1. the low thermal resistance allows heat to
flow easily from the hot side to the cold side. a thicker device would reduce
this heat flow, but that would increase the electrical resistance and the
required electrical power. in 10-20 years, we might see devices using better
materials (skutterites) with a 20:1 ratio, according to nrl researchers...
