I wish they had higher efficiency.

Their efficiency is determined by the difference between the hot and cold points like every other heat engine

Whatever happened to the high efficiency thermionic generator that popped up a few years ago? If I recall correctly, they were claiming 30%+ efficiency.

I managed to get a 70° deltaT from two of them stacked last week

30% is still peltier tier.

Heat pumps are much more based.

The fuck? That's equivalent to saying "the efficiency of a car engine is determined by how much gasoline is in it."

It's right, idiot. That's basic physics. Explain why the efficiency increases with the difference in temperature is this is not the case.

There are other factors that also influence efficiency. The temperature difference only governs the max theoretical efficiency.

It's also proportional to the real efficiency in any situation and pretty much all other factors that affect efficiency will be static for a given device. That's why I said it determines the efficiency.
