Aren't radio waves that are used to carry information energy? It has been proven that energy can be transmitted wirelessly (though it has never [as far as I know] been implemented). Can't you technically power your home at least partly by intercepting radiation being emitted by telecommunications devices like satellites?

Why aren't those signals used as a means of "recycling" energy yet?

i like how you used brackets as a form of double parenthesizing (althought in mathematics, [pretty much the opposite of english {and way cooler}] its the other way around).

Is there anyone that wants to give me a serious and straight-forward answer instead of ad hominem attacks that point out my ignorance or poke fun at how I type?

This is relevant to your interests.

OP, you can extract energy from radio waves, certainly. Early radio receivers were called crystal sets, and they didn't even require a power supply. The energy in the incoming radio waves was enough to power the headset.

Thing is, this is a tiny amount of power. Something like billionths of a watt.

>> No.4811333

This already exists, google crystal radio.
The reason we don't do it, is because collecting 'a lot' of that energy is just more trouble than it's worth.

I know it likely cannot be used as a standalone power source but can it be used as a secondary "bonus" that helps certain devices economize energy?

still wireless.

And you gotta start somewhere. Tesla is too much for tptb so it looks like incremental increase will be the adopted method. That way, the necessary control and security measures can be developed alongside the increasing range.

You would not recycle much energy from this. You'd get nothing essentially.

Partly, yes. But the energy density is so low that the cost of doing so is far greater than the cost of just buying your power like a normal person. (Cellular and radio towers provide far more energy at this level than satellites, btw.)

I have seen people put induction coils under high voltage power lines and use those to siphon off energy. It's stupidly dangerous, however, and I wouldn't recommend it.

>> No.4811520

>>4811499
What, you're afraid of a little high-voltage arcing? WHIMP!

Also... the entire point of high voltage power lines is that they don't carry much current, so I don't think you could get much power via induction (especially since you'll have to place the coils so far away from the power wires).
