I think there are some applications though. I remember PWMing a peltier element to cool something to more or less exactly 35°C. I didn't need to be efficient cooling, it just needed to be reliable under space constraints.

I am no hardware guy and I remember there was a giant heatsink despite the constraints. It was some kind of photosensor + lamp if I remember correctly.

I think there was also some software logic to reduce water condensing at something too cool compared to the ambient temperature.

Obviously there are applications. There's one on my CPU.

The question is: Are there large-scale applications?
