in which year will wireless electricity be widely used?

Question

remember 40 yrs ago people laughed at the idea of cell phones.

Answer 1

Wireless communications (radio transmissions, etc.) deal with propagation and reception of electromagnetic waves traveling through space at the speed of light as photons (similar to light). A receiver must detect a vanishingly small signal then magnify it in one or more amplification stages using electrical power.

Electricity, for example the current that heats your toaster, is more powerful and is transmitted from the power station to your home through electrical conductors because it is a flow of electrons (not photons) traveling much slower than the speed of light. Electrons can flow through a vacuum (as in a vacuum tube) or through the atmosphere (as in lightning). It is much easier to guide the electrons through wires safely to their destination (and through a power meter?) than through air. Therefore, wireless transmission will likely find special applications when a compelling reason if found to eliminate wires. It may be used only for special purposes rather than to power homes and factories. Forty years from now people will still not laugh about accidental electrocutions.

Answer 2

Not in the foreseeable future. Truth is we don't know how to efficiently (that is the key word here: EFFICIENTLY) send electricity wirelessly over great distances (that is unless you consider battery power is sort of wireless electricity), so anticipating when a still unknown technology would be popular is impossible to do (and imagine the nightmare for the utility company: unlike phones where you have a number that basically identify you though an encoder/decoder for a radio signal that carries several conversations at the same time, and only extract what is meant for you, there is no way to tune in a frequency for power so that what you woudl take could be told from what your neighbor uses -- unless someone comes with a clever idea, but this brings us back to the original point: we don't know when or even if it will happen)

As for cell phones, 40 years ago, there were things like portable radio - they were bulky yes, but they worked. Anticipating them being reduced and becoming widespread was only a small stretch of imagination; most of the technology was already in place. Not so for wireless electricity.

Answer 3

A.) I don't think 40 years ago people were laughing at the idea of cell phones (at least in the engineering/science field).

B.) Given known science... never. Transmitting power wirelessly inefficient to the point it is pointless except in highly specialized cases. Secondly, it would be very dangerous, unless you like dodging high energy arcs of electricity all the time.

Answer 4

There is not necessarely wireless electiricity per se as it is a combination of a few things.

Solar energy can more easily be convertted into sub-optic light for transmission through fiber optic,.

Tesla's design can pull static electricity out of the air and amplify it to warp magnetic feilds. If we combined this ability to create a magnetic feild we could use a repulsar field on the ice caps to push agains the directional flow of the neutrinos. Like a nutrino sale/shield.

Answer 5

In the early 1900's Nikola Tesla experimented with wireless electricity during his Wardenclyffe experiments and it did work. In other experiemnets he lit light bulbs by grounding the negative terminal to the Earth. Imagine sticking a household light bulb in the ground and seeing it light.....like Granpa from the Munsters! The project was cut short when his financial backers inclduing Westinghouse decided that wireless electricity would not be in their interest because it was a threat to the infrastructure which they had already paid to create.

Answer 6

It has been widely used for well over 50 years. Anybody who uses a radio is using wireless electricity. Same thing goes for television, before cable TV.

Answer 7

I saw in Popular science maybe in 12 years However Progress energy solutions say 25 at least we are only about 6 years away from fiberoptic energy distribution check out energy dept on a search engine

Answer 8

Hmmn.. you are right.. It will be availalbe for use soon after some one invents a system by which human beings and other living things are not affected by the electricity passing through them.

Answer 9

after 100 to 1000 years all people in world use wireless electricty
but in most advance countries it is possible earlier

Answer 10

well not to far because wireless electricity was allready used way back in 1899 and the thero has not become a pratcice...so in any other terms...(very soon)
