Microwaves are very efficient at converting electricity into a beam and then back into electricity.

There are issues but the largest is relatively simple. It costs a lot of money to put stuff in space. If you can drop the cost per ton then space based solar can work.

What would helium3 do? We have no fusion power plants hence Helium3 would be of absolutely no use. A nuclear power plant on the moon. I mean that woudl qualify at the stupidest idea ever presented. Getting to the money is expensive, per kg it is nearly 12x the cost of getting into orbit. Nuclear power plants also weight tens of thousands of tons. The cost to transport a nuclear reactor to the moon would be in the trillions of dollars.
