Is there any way in the near future that our electric power be wireless??

Question

in these way, there will be no street cables, no electric post and no hazardous materials in the street..

Answer 1

This is a very interesting topic that is bothering me for years and it is not as farfetched as a lot of people think.There are people that work on that and there is some examples that work on a small scale.
A team of Japanese researchers has created a novel wireless power-transmission device that is thin, flat, and flexible. Based on a sheet of plastic, the device can be put on desks, floors, walls, and almost any other location, delivering power to electronics placed on or near it without the use of cables or connectors. Go to this site and have a look.

In the 1980s, Canada's Communications Research Centre created a small airplane that could run off power beamed from the Earth. http://electronics.howstuffworks.com/wireless-power2.htm

In terms of physics it is simple enough. Solar panels are an example of electical power transferred wirelessly (as visible light from the sun). The same principle can be applied at many different frequencies.

However, there are some issues.

1) Power is lost based on the distance squared. This contrasts to wired transmission, where it is (more or less) directly proportional to distance. Therefore wireless systems become less efficient than wired systems at longer distances.

2) Smaller transmission components require higher freqencies. But current technologies tend to be less efficient at higher frequencies.

3) At higher powers, wireless transmission becomes dangerous. Body tissues tend to absorb the energy and heat up as a result. Even at lower power, there may be health issues from long term exposure.

Ultimately, wireless power sources will have to go hand-in-hand with lower power requirements. This may eventually work for electronics (running your iPod or cellphone off a wireless system), but not for anything where there is a large power output required because of simple physics (elevators, street cars, heaters and A/C).

Answer 3

Actually, its already been done. Unfortunately it proved fatal but thats what it was intended for. Transferring power wirelessly is possibly. Ever heard of Nikola Tesla, he basically did just that. Tesla coils.. thats what they were except they were for warfare not commercial use. It will be a while before anyone masters this feat. Cell phones are being looked at for causing cancer... theres no WAY we will transmit power, in the form of electricity wirelessly, SAFELY for a long time.

EDIT

once we are able to find a safe way... we will then have to find an EFFICIENT way of doing this.

Answer 4

I believe someday we might do that...probably the voltage levels might differ so that it is not hazardous.

Imagination has no limits, if somebody didn't believe that we could have wireless communication, it would not have eventually turned up.

So, definitely electric power might become wireless, but probably not in the near future, the emphasis as of now is on conserving and rejuvenating energy rather than transmission.

And Necessity is the only mother of Invention.

Answer 5

nicely i pay attention gas is meant to stand as much as twelve money to no longer far into the destiny yet good day...what would have been a greater powerful ingredient to spend your money on (fairly of a gas hogging truck) would have been an electric automobile, a bike, or some bus tickets! international warming is an argument that individuals could be taking greater heavily i know its no longer that user-friendly and electric automobiles are very costly, yet its completely nicely worth it it relatively is our plant that we are ruining in an attempt to answer your question... no, i doubt it will be nicely worth something the way gas expenses are looking now

Answer 6

probably not, the only way to transfer electricity through the air would be to create huge amounts of voltage, like lightning. and even if we were to do that there would be a big risk of the electricity not going to the target in which we intended.

Answer 7

You could use microwave towers to "broadcast" power. I think it would be pretty risky though.

Radio waves can power a small radio so the signal can be heard without an external source. The coil around a magnet is enough.

Answer 8

Trust me. Technology = Art. When it comes to Art there are no limitations. There are unheard of technologies out there that are still yet to be discovered/invented. Things that no human on earth could ever dream of right now.

And as the old adage goes. "If there's a will, there's a way".

Answer 9

We haven't mastered wireless power yet: at least not without hurting anyone.

Answer 10

That would be a shocking, and downright re-volting development :p
