Almost all discussion of beaming power between space and Earth is in the context of power generated in space (such as via solar panels) and beaming it to Earth.

Almost all discussion of beaming power between space and Earth is in the context of power generated in space (such as via solar panels) and beaming it to Earth.
I wonder if it would ever make sense to beam power from Earth to space? For example there are places on Earth that would be great for large solar farms but don't have sufficient transmission lines to get that power to where it is needed.
Perhaps power from those Earth-based solar farms could be beamed to relays in space that would them beam it down to receivers on Earth that can get the power to where it is needed.

A re-run of the Berlin Wall might do it, but only if the city to which that is an apt analogy is OK with totally enclosing it's entire land area in antenna.
