How can I make free energy?
The mechanical energy is converted into electrical energy by generators, the important elements of the generators are the magnetic field and the motion of the conductor in a magnetic field. The free energy generator is a device, which is used to generate electrical energy based on the neodymium magnets principle.
Do LED lights work without electricity?
If the switch is OFF, this light will still work. Just flip the switch ON.
