Can we imagine a large laser beam that sends energy into space in the form of light? (long wave infra red? Or another wave length that goes all the way through the atmosphere). If we were to feed this big beam with electricity made of ambiant energy (not fossil fuel, not nuclear), would this contribute to reducing the heat on earth?
It would look like a massive waste of energy, but from a pure system perspective, such a waste would be a way to reach an equilibrium. We would essentially be dumping into space the extra energy we have imported into the system by burning fossil fuel.
Please point it out if I am voicing thermodynamics profanities or why such apparatus would be technically not achievable.
Disclaimer: I am not a phycicist nor an engineer. I trust experts help us focus on what is the most effective way to fight climate change, which is to reduce the greenhouse effect by cutting down on emissions of CO2, methane and the like. I ask this question humbly because I am genuinely curious to fill in some gaps in my understanding of thermodynamics and nurturing this curiosity prevents me from becoming cynical or pessimistic. Sorry if my question is dumb or grotesquely science-fictionish
