The thought of beaming energy to an energy-hungry Earth from space has long been studied, even advanced over 80 years ago in science fiction.

Fast forward to the 21^st century, investigations here on Earth and now in space seemingly bolster the concept. Still, space solar power beaming is viewed by some as a truly far out and off-the-beam technology, an economically dubious concept that does make for good science fiction.

The SOLARIS initiative is preparing Europe to make future decisions regarding the prospect of space-based solar power.

I reached out to several technologists as to what’s new, what’s old, and what’s still missing to plug in space power transmission to Earth.
