Will solar operate if there's a nuclear winter?

[–] bstix@feddit.dk 8 points 1 year ago (1 children)

In case of nuclear winter, I don't think renewable energy is going to be the main concern.

However, it is possible to put solar panels on satellites that transmit the energy down to the surface. It's costly and dangerous, but a benefit over surface solar is that the satellites can point at the sun for longer time during days and send the energy to places that are not in the sun, thereby producing solar power 24/7. It's wildly impractical and expensive, but in case of nuclear winter it may be a realistic solution.

Wouldn't the dust in the atmosphere also prevent energy transmission just as it does solar?

Wind, still works

[–] Excrubulent@slrpnk.net 2 points 1 year ago

You'd use frequencies that can penetrate cloud cover in that case, it wouldn't work otherwise because then it would still be subject to weather.

As long as you clean the surface of the Solar pannel from snow I dont see why to shouldn't work. Even on cold and cloudy days our panel works.

Gonna need a tall ladder.

https://en.m.wikipedia.org/wiki/Nuclear_winter

Nuclear winter is a severe and prolonged global climatic cooling effect that is hypothesized[1][2] to occur after widespread firestorms following a large-scale nuclear war.[3] The hypothesis is based on the fact that such fires can inject soot into the stratosphere, where it can block some direct sunlight from reaching the surface of the Earth. It is speculated that the resulting cooling would lead to widespread crop failure and famine.

No, you will be put into the matrix.
