If you are aware of Nikola Tesla and his “free energy” inventions, you should know that wireless electricity is real. You should also know that it is possible to extract energy out of thin air, because the atmosphere contains countless atomic particles that are charged with enormous amounts of energy. The hard part is learning how to tap into this energy.

WATERTOWN, Mass. (CNN) — Katie Hall was shocked the second she saw it: a light-bulb glowing in middle of a room with no wires attached.
Looking back, it was a crude experiment, she remembers: a tiny room filled with gigantic cooper refrigerator coils — the kind you’d see if you cracked open the back of your freezer.
She walked in and out between the coils and the bulb — and still the bulb glowed.
“I said: ‘Let’s work on this. This is the future,’” Hall said.
What’s the trick?
“We’re going to transfer power without any kind of wires,” said Dr Hall, now Chief Technology Officer at WiTricity — a start-up developing wireless “resonance” technology.
“But, we’re not actually putting electricity in the air. What we’re doing is putting a magnetic field in the air.”
It works like this: WiTricity build a “Source Resonator” — a coil of electrical wire that generates a magnetic field when power is attached.
If another coil is brought close, an electrical charge can be generated in it. No wires required.
“When you bring a device into that magnetic field, it induces a current in the device, and by that you’re able to transfer power,” explains Dr Hall.
And like that, the bulb lights up.
