What someone needs to do it turn all radio waves into heat. I have about 50 wifi connections pretty close to my house.
Something you can plug anything into, IE phone lines, cable that somehow turns it all into heat.
There “free” energy!
Might be able to heat a very small space. lol
Heat? How about electricity? I recall one AM radio project that used a long wire and a neon bulb...if you lived in the vicinity of a decently powered AM station...
