- TL;DR Summary
- Electricity from (ambient)heat - molten silicon batteries work that way
I am not a physicist myself, so i ask you for patience.
I am posting my post here, althougt it also covers (useful)heat transfer (out of hot towns) or air-conditionig. At the core of question is quantum physics, is it theoretically possible to produce a chemical substance, which would absorb two or three infrared photons and emit one photon suitable for voltage production in photovoltaic cells. Technology for convertig heat from molten silicon emitting visible light to electricity in photovoltaic cells alreay exists (https://silbat.com/).
But it would have to work at lower temperatures than molten silicon batteries. Maybe efficient thermoacoustic heat pump with no moving parts(except the loudspeaker) could rise the temperature from ambient to some 300 degrees Celsius. Would this produce enough IR photnos to ba captured by chemical substance which would triple their frequency, to be suitable for photovoltaic cells?
It all depends on many variables, but could such cemical substance be produced (i found mentioned class of substances called "porphyrin derivatives". https://en.wikipedia.org/wiki/Two-photon_absorption)?
Thank you for your answers.
