>Power transmission via radio waves can be made more directional, allowing longer distance power beaming, with shorter wavelengths of electromagnetic radiation, typically in the microwave range. A rectenna may be used to convert the microwave energy back into electricity. Rectenna conversion efficiencies exceeding 95% have been realized.

WAT

WHY THE HELL AREN'T WE WORKING ON A DYSON SWARM MODULE RIGHT THIS MOMENT?

You could balance a satellite in solar orbit between the solar wind and the solar gravity. Then you could just beam tapped power with a microwave laser to Earth. Radio frequencies are hardly affected at all by the atmosphere.
