History Channel is spewing more nonsense about how ancient lost civilizations used obelisks to transmit electricity to one another,...or something.

QUESTION: Nikola Tesla proposed a wireless electrical grid, using the conductivity of the ground or the air. Why wasn't this implemented? What's the limitation?

>limitation

It takes shitloads of power to send the electricity out

WIRELESS POWERERERER, because lightning is cool and that reasonably small distance doesn't require much power to transmit across or something

>> No.1196464

just wait until we get this whole nuclear energy thing down, shit will be so fucking cool.Wifi EVERYWHERE lol

>> No.1196469

Wires are one hundred billion trillion times more efficient than generating enough RF to induce a current a few meters away. We got limited capacity to create electricity bro.

bagsy making the first wifi electro glove gun... eat my focused electricity bastards!

I dig. Thanks for the replies, everyone.

But while we're on the subject; are there any weird and legendary Tesla stuff that the world of science pursues? It was said that the Justice department raided his labs and took all of his notes etc. upon his death. Did Tesla really take any forbidden turn-of-the-century high-tech deathray type shit to his grave with him that we can't duplicate today?

inductive power is super fucking wasteful and useless for anything but short-range charging (you can get wireless charging pads right now)

The required energy needed to power the such generators would be RIDICULOUS, especially as a world wide network just cause our atmosphere's air doesn't conduct very well. He actually made a Van de Graff generator in his back yard that lit a light bulb 30 or so yards away =). The other limitation is how it's uncontrollable, people could "steal your electricity" etc... The power is transmitted in all directions, meaning the majority of the huge amount of power you transmit is lost.

What?
Well, we've made "lightning" weapons that ARENT tasers or anything that travels along a wire. But to direct the surge they send out a jet of gas that is more conductive than the surrounding air so the current travels down that. There isn't much of another way of doing it effectively yet, and there are a lot of flaws with that technique.

jpmorgan financed the wireless grid with 250000$, but withdrew when it became apparent there was no useful way to actually charge people the amount of electricity they used. check current economist mag


case solved.

Protip: tesla was a fucking nutbag who happened to work on AC with some other folks

>> No.1198767

because you could never know if you were making too much, or not enough power, because there would be no way to know who was receiving the power.

because Edison is a fucking lying faggot douchebag.
