can we transfer energy from one place to another without any wire?

Answer 1

Energy can exist in many form...
Considering the forms of potential energy:
* Chemical energy - energy locked up in a chemical form such as natural gas, or petroleum can be sent by oil tanker or gas pipeline.
* Nuclear energy so an atomic bomb can also be sent on a rocket.
* Potential energy say in a catapult transferred to a rock or a cannon ball sent into the sky and it comes down at high speed somehere else.

However I presume you were talking here about electric energy, so this is sent down wires, either with low power as in a phone conversation or high power for power distribution.
Light is a form of electromagnet radiation and can be sent via a laser beam through the air. Radio waves, Heat, microwaves, X rays etc. are also forms of electromagnetic radiation at different frequencies and can also be sent through the air with the need for wires.
If the question was how can I get electricity in my house without having a generator or being wired up to the electricity grid then Nicolas Tesla was the pioneer of this using ultra low frequency electromangent waves based at Wardenclyffe Tower, Long Island a century ago. The idea was to inject the energy into the earth directly closing the circuit through the conductive upper atmosphere. Unfortunately he ran out of funding before this could be fully demonstrated.

Answer 2

Any form of radiant energy can do that, the problem is that most means of transmission are very, very weak and inefficient.

Recently, though, there has been a great deal of research into microwave energy. This is essentially a long-wave laser that can transmit a great deal of energy in a very concentrated beam. There is talk of putting huge solar sails into high-earth orbit and beaming the energy down to earth.

Answer 3

What sort of energy.

Heres one way.

Fill bucket with hot coals.

Walk across room.

Done.

If you mean electrical energy, it is tricky to transfer energy at commercially useful power levels other than in wires because most media absorb to much of the energy.

In addition, if you used say microwaves, then they would fry anything that crossed their path. Eeek.

Answer 4

Yes - the sun does it every day, 24 hours a day, 365 days per year.

Also, more terestrially, hydraulic systems transfer energy without wires, although they do use pipes.

Answer 5

Radio waves are also a form of energy that is transmitted without wires.

Answer 6

light and sound energy doesnt require ne wires 2 b transferred

Answer 7

Yes but the amount of energy received decreases with the square of the difference.

Answer 8

yes, we are already transferring energy by transmitting radio and telecasting TV programmes etc. through radio waves.

Answer 9

yes think of wireless networlprotocols, cell phones, acid also conduct electricty ditto water

Answer 10

yes .By radiating property of energy (light &heat)
