Question

The news articles about wireless electricity...do you think there will be a day that cars will run electrically (without batteries, without charging)?

Answer 1

The idea of wireless charging is just a theory-absolutly not practical-

,let as imagine :for exchanging wireless data we need a towers of communication that consumes electric power in the order of megawatts regarded that the data signals are broadcasted in the range of milliwatts,so imagine that the data signals are replaced by power signals with several watts of power,so it cant help?

Answer 2

losses would be a problem. You can certainly get things like ezpass to vibrate with an RF field, and vibration can be changed to electrical energy, but no way would you transmit energy efficiently.

If you're just projecting the signal around like wireless cellphone towers, just think how little actually gets to the source that needs it.

If you could focus it to a beam, that might be more efficient, but then you'd need tracking technology and I wouldn't want to stand in the path of that energy wave.  

Answer 3

wireless electricity has been talked about to the point of having massive solar panels on the moon and beaming the power back to earth...

we do have wireless communications and broadband so why not wireless electricity..

if your question means can electric be beamed to a car and then it can drive, i dont see why not one day - however a battery will be needed to store this power etc..

there is a possibility that car may drive without charging if it can utilize the particles in the air and convert that to a form of thrust power...

but i guess batteries will still be needed, to power the computers or lighting systems etc....the batteries could be self charging..so no need to plug in to a socket/./.

Answer 4

Even if you got electricity from a satellite or another source, you will still need to store that energy for situations where you went into a tunnel  or lost the connection in some other way.

Answer 5

no, not the way it looks now.

the "wireless electricity" is good only for short distances, low power, and it has lots of losses.

Do you want Megawatts of electric power going through your head all day long?

Answer 6

ugh, not another wireless energy question.

short answer:NO

wireless electricity is basically impossible, any technology today that achieves wireless power works on the principle that you can convert electrical energy into light/heat/whatever and then turn it back into electricity at the destination. You can not transmit electricity itself wirelessly.

its like shining a light bulb on a solar panel, which is horrendously inefficient

also, current electric motors that produce enough force to make a flying car are way to heavy for a flying car, so even with wireless power, you'd want a gas engine
