A Skeptic’s Take on Beaming Power to Earth from Space

Cars That Think

But that might be mitigated, in theory, if space solar displaced fossil fuels and helped the world transition to clean electricity. Low-cost, low-mass, and space-hardy versions of these technologies would be required, but engineers trying to draw up detailed plans for such satellites today find no parts that meet the tough requirements.
