In this age of wireless technology, why can't we transmit electricty via wireless connections?

Answer 1

Tessla had a plan for it.

It really works, and if you got up close to your local commercial radio broadcast antenna with the right length antenna you could take usable power right out of the air.

The catch is that you would black out everyone behind you. So they don't like you doing that to their signal, and they put their broadcast antenna way up in the air, and behind locked gates.

Also, if they broadcast all power that way then it would drown out the broadcast communications on adjacent bands. Also since the intensity of a signal decreases with the square of the distance (at twice the distance you'll have 1/4 the power) , you'd have to be pretty close to the source for full power.

If things had gone Tesla's way, we would be getting our TV, radio, and phone messages only through wires, and satellite communications, cell phones, and radio stations would never be.

Answer 2

Hello,

(ANS) The problem I think is that, you have to understand what electricity is and what wirless is before you understand why electricity cannot be transmitted over wirless.

No.1 Electricity is the flow of pulses of electrons i.e. fundamental particles which are positively & negatively charged (at the atomic level that is).

No.2 Wireless uses broadcast frequencies to transmitt radio signals, radio waves across thin are. These radio waves are at specific frequencies.

Radio waves are generated through the use of electricity but are fundamentally different from electricty itself. One can be used to create the other but it doesnt work successfully in reverse I think this is closest to the reality & your question.

**Plus if it could be done safely & cost effectively I think humans would have developed this by now.

Research is already being done in this field, with a view to transferring energy wirelessly (albeit in low power devices) so you can charge things such as mobile phones by standing them close to - but not connected to, a charging plate.

I have an electric toothbrush that charges by standing on a plastic base and there is no connection between the brush and base. This is called inductive coupling.

Answer 4

It relies upon on the variety of broadband connection you've. If the relationship is more effective than 54Mbps (assuming your prompt gateway is 802.11g) then you definately receives a more effective powerful connection connection on to the modem. Its is fantastically not likely that your connection to the cyber web is so quickly so it doesn't count number in case you connect by potential of the prompt link or without delay. The prompt routers that you get as we talk are a lot faster on the prompt link than what's given to you by potential of the broadband connection

Answer 5

electricity is totally different from bluetooth and infared.
transmitting a extremly small amount of electricity maybe possible ,but that cant really power anything, so it is'nt worth developing this 'technology'

Answer 6

data can be converted to harmless radio waves that can pass through building and bodies without causing damage.

Electricity cannot. It is energy. If it were wireless, while passing through your body, it would kill you.

Answer 7

If it was possible (i think it may be in a vacuum) would it not fry everything it passed through in the same way as microwaves?

Answer 8

Nicolai Tesla did that a hundred years ago. The problem is - they would not be able to CHARGE FOR IT $$$$$$ !!!

Answer 9

It's possible using microwaves...

Answer 10

i think its to do with particles and waves and how they can be transmitted
