*Over long distances it's much easier to transmit data than power, so if
space-based power transmission to earth is economically viable (is it?)
then it would make even more sense to have power satellites use their
energy to run data centers that are also in space. After all, these days
running data centers is the economic sector where energy usage is growing
the fastest, so why not build them where energy is the cheapest? *
