> Second, utility is limited because we already have a huge fusion reactor in the sky beaming energy to us which we simply need to build receivers for. Said fusion reactor's transmissions are blocked by the earth's bulk for half the day on average, including peak demand hours. The rest of the time it can be partially absorbed by cloud cover, greatly increasing the necessity of spare capacity over extremely wide areas. Space-based solar doesn't have these issues. It has unfiltered sunlight 24 hours per day.
