Infrared Detectors & The 2nd Law of Thermodynamics

[hutchphd]

Shining a laser at an underwater photodiode to produce power violates no laws of thermodynamics. I could run solar panels in my swimming pool if I really wanted to. Why do you wish to do this?
This is quite different from your initial scenario.

This is quite different from your initial scenario.

So now I make a really big detector and point it at a 300k lake surface, to heat the 320k water with the 3.5 micrometer photon flux off the 300k surface, with no laser.

This thread has run its course. You've been repeatedly told that what you suggest isn't possible and you're chasing your tail (and getting others to chase it) making little changes to your scenario to try to keep it alive. Thread closed.
