The issue you speak of doesn't necessarily instantly break the TEC, it just limits its number of thermal cycles in a lifetime. Take a 40mm peltier and this thing, and then power cycle them again and again. I bet the 40mm will keep doing that about four or five thousand (literally) more times after this monster cracks and breaks from the thermal cycling.
I imagine there is some size out there where it will break the first time, but it would be one big pelt. At half a kilowatt of juice, this thing seems big enough. The thing's big enough and powerful enough to move the heat off a small cooking hotplate! Pretty useless for CPU cooling, but its already been said: It would make for an awesome in-line chiller!
