How can I generate a power source via EMF waves around us without using any other power source?

Tell simply and more efficent way while dealing with it. Also it must work and practically available as well as possible.

I asked this question some time back and got no answers - There's a lot of power coming down from those overhead power lines which could perhaps be caught by some kind of antenna and fed into a rectifying circuit.
There's not a lot of loss from an overhead line, that's why they are high up and spaced just so. Increasing those losses is stealing electricity. Someone in England was convicted of stealing electricity because he arranged his house wiring to catch the emissions from the big Long wave transmitter in Droitwich. Presumably he only had a DC system.

It's called a transistor radio. Some work without batteries:
