A device for generating electricity from free energy
First of all I must say that this is not a quantum free energy generator (QEG) developed by Nikola Tesla. The concept of free energy would mean that the energy is somewhere in the air and it can be pumped out and used. The law of conservation of energy, however, says that there is no power or destroyed, only changed its form. This manual should for accuracy before calling device for converting electromagnetic waves into electrical energy by means of electromagnetic induction. Electromagnetic radiation is all around us. It occurs naturally or as electrosmog, who originally are radio waves, wifi, mobile phones and other electrical equipment. This radiation can capture, produce electricity, divert and use, for example, to light up the LEDs.
In Excel I have designed a spiral coil (antenna) on the circuit board. The coil has a radius of 2 cm but after the development of the spiral should be the length of one meter.

PCB can do classical way by the photoresist, but I used an ordinary tape, to which I figure burnt by laser.
Gravrírovanie masks for printed circuit board using a 1W laser.
Parched places that create a mask for etching. I used etchant želzitý chloride (FeCl 3), but it can also be any acid.
When you peel off the tape remain protected, neodleptané, creating spiral. At the beginning and end of the spiral I connected LEDs.
Looking through a microscope it can be seen that the details are not the most sophisticated etching. Conductive paths are, however, functional and nowhere there to short circuit.
The back side of the PCB. Parts are usually secure the opposite side of the PCB. But I wanted to see the spiral and at the same time as the diode lights.
If the coil, the alternating magnetic field in the coil is induced stress. If the end of the coil interconnect, so it will flow in electricity. The same principle works for RFID chips, which thus gain power. The device will therefore operate in blískosti smart card readers, električeniek, contactless payment terminals, wireless chargers, transformers and the like.
I used the LED 1,6V_20mA. If the coil was much larger and the LED would be low current (1,2V_1mA) and would operate either a greater distance or in a weaker magnetic field. The downside is that at higher magnetic fields (eg. In the vicinity of the microwave) could burn. The highest efficiency is achieved when the size of the coil in resonance with the wavelength of electromagnetic radiation.
