Most of the time, we consider heat output to be inefficient. It only works here because heat happens to be its purpose.

You could say it's 0% efficient.

I dunno, I’m seeing some light.

Light is absorbed by materials and ultimately becomes heat.

Doesn't everything ultimately become heat?

[-] unrealMinotaur@sh.itjust.works 1 points 2 months ago

Yes, that is why it states "this is what peak thermodynamic performance." In electronics people are taught that no device is 100% efficient because energy is lost as heat. A heater is 100% efficient because everything becomes heat.

Four or five?

and what happens to the energy of said photons once they interact with your retina?
