If these become popular, maybe you could create a new solar panel that absorbs the wavelengths emitted by these air conditioners in order to create electricity
These panels reject heat at a rate of up to 70 W/m^2. A good solar panel absorbs 20% of incoming light, which typically peaks at about 1000 W, so a solar panel reduces temperature by 3x as much.
So... you could just do that.
Furthermore, air conditioning isn't lowering the temperature of a system by the energy consumed. Rather, it acts like a heat pump which usually pumps more energy that is used. So 200 J/s of electric power running a typical AC unit would likely reject more than 200 J/s from a building.
Solar panel efficiency decreases with rising temperatures, so maybe increasing its emissivity in the infrared window could improve efficiency.
Could you create a solar panel that generates energy during the day and rejects heat during the night? Would it be efficient at either task?
