World's first real Free Energy Flashlight - no shaking - no batteries! No Solar

[MileHigh]

Indeed, and I am going to take a wild guess:  If you buy an "expensive" LED flashlight that costs $20 or $30, it contains a high-efficiency voltage-to-current converter, so that you can keep the LED flashlight at the same brightness and control the power consumption of the device as the battery voltage changes.  Hey, it might even make the LED flash at a high rate so you can save more power and it may even give you give you two brightness (LED current) settings.

Or, for a hundred bucks you can buy a Chinese Dollar-store flashlight that costs $1.664 in volume without the super high tech voltage-to-current converter.

What if the antenna wasn't made from copper but was made from graphene,

You can perhaps make the antenna more efficient, but you still cannot harvest more than the energy that is actually available. So if there are 10 nW/cm² of ambient EM energy, with antenna efficiency of 90% instead of 60%, you get 9 nW instead of 6 nW, but it will still not recharge your battery.

Fahoo Doray.

I have always wanted to say that.

Well it is indeed possible to make a self charging torch,although it would have to be a little more efficient than my setup. But non the less,it dose work,and dose self charge.
