Everyone were also betting on quantum computing and the hydrogen energy revolution.

My napkin math says that, for a system at around 75°C, you would need about 13,000 square meters of radiators in space to reject 10 MW of heat.

why do you think they are betting on it if it so obvious to you that it won't work?

    Just because some CEOs pour billions into fantasy projects it doesn't mean they're viable. Otherwise we all would be in the metaverse wouldn't we?

      Sure, I don't claim all of them go well. Do you want to run a hypothetical exercise on how many they get right vs wrong? And based on that we can see if this is a "fantasy" or not?
