I wonder if "battelites" might be profitable. Like an pay-per-usage energy grid in space with battery backup that can beam power around to other satellites that might not have easy access to power, or have their power grids temporarily obstructed.
Yes, but it’s a guaranteed event, so it needs to be accounted for if you’re serious about engineering.
The accounting could just be, we accept that downtime, it’s all calculated in advance and we’ll prepare the system for it, but it still needs to be considered.
