The Fuelfree Generator produces electricity, by harnessing the thermal energy of its surrounding air.

  • The generator produces an electromagnetic wave which polarises the air. This creates a decrease in the air molecules’ degrees of freedom, and as a result, a decrease in the air’s kinetic energy.
  • The air temperature in a diameter of about 3 meters around the generator drops by about 7°C.
  • The outside environment, further away from the generator, is enticed to transfer heat into this relatively cold area, as heat flows from the hotter to the colder region.
  • In the meantime the electromagnetic wave loses some of its energy.
  • This allows the kinetic energy contributed by the outside environment to have a greater impact on the air molecules closer to the generator.

  • As the air molecules’ kinetic energy increase again, they act as tiny electric dipoles, and the resulting (statistical) effect is to strengthen the electromagnetic wave.
  • The stronger electromagnetic wave begins a new cycle, by cooling the air again.
  • This oscillatory cycle is maintained, and the environment continues to pour thermal energy to the generator’s vicinity.
  • This energy sustains the electromagnetic wave, and produces a magnetic effect inside the generator.
  • The magnetic effect is used in order to generate electricity.
  • There is no need to store the electricity, as it can be supplied on-demand.

The Fuelfree Generator is a about 70cm by 70cm by 50cm in size.

The first generation FFGs will each deliver a continuous supply of electricity at a sustained rate of at least 3kWh. This is equal to more than 2000 kWh per month. According to the U.S. Energy Information Administration (EIA) the average U.S. residential customer consumes about 900 kWh per month.

It is hard to determine the final cost of an FFG, but we estimate that the final cost of a first generation FFG will not exceed 3000 USD.
