3 days agoElectromagnetism is very flexible and theoretically you could put a lot of energy in a small place with it and there’s things like a strong enough magnetic field levitating a live frog.
That said it doesn’t seem very practical and it might not even be close to safe to walk around something with that much power like in the sci fi shows.
I use a USB connection to my UPS for the shutdown signal not Ethernet
