The attenuation is less than 50% at the wavelengths used by solar panels.

What’s the practical solution to heat radiation that doesn’t require running your chips at infeasible temperatures?

One thing that I haven’t seen represented as a risk in space based datacenters is the satellite reentry debris pollution. We are essentially allowing a constant rain of heavy metals, silicon, arsenic, and other nasty things if this idea goes to scale.

Even if all the technical issues can be worked out, which I doubt, the incentives are there to pump as many as possible up there. I don’t think we want to live with that raining down on us all.

Heat radiation is not solved at all due to (almost) lack of atmosphere. Look at ISS, enormous panels to radiate the heat away for an energy budget of only 170kW.

Any out there methods to send energy down besides rf? Chucking battery down? Dangling catenary wire to a high altitude battery plane?
