This begs the question: Why hasn't any industrialized nation utilized the concept of wireless power transmissions? Why are we still plugging shit into the wall? Mainly because it's impossibly inefficient, plus the possible health effects from massive amounts of RF energy.
It's much the same principle of as a flashlight. There isn't that much difference between light, heat, and electircity, it's all just eneergy at different points in the electromagnetic spectrum. Generate it, focus it, and beam it to a reciever.
FWIW, this technology is already in use in the form of RFID tags, which turn the radio signal they recieve into electricty, and use that to run a radio transmitter long enough to broadcast their ID back. That's how those thruway toll tags work (EZpass if you've been to the northeast)
This could be a future power source involving generating massive amounts of power in space somehow, then focusing a microwave beam onto a terrestrial collector. It would also double as a handy death-ray by changing it point of aim. |
