Space-based solar power is getting serious—can it solve Earth

For space solar, power beaming needs 75% efficiency, Vijendran says, "ideally 90%." The safety of beaming gigawatts through the atmosphere also needs testing. Most designs aim to produce a beam kilometers wide so that any spacecraft, plane, person, or bird that strays into it only receives a tiny—hopefully harmless—portion of the 2-gigawatt transmission.
