Definitions

  • An energy generating apparatus for converting energy from a fluid in a fluid source into usable energy
  • hydroelectric dams usually include a turbine which harnesses energy from water flowing from an upper body of water to a lower body of water. While hydroelectric dams are very effective, they can only be used in limited places, i.e. on rivers.
  • Peloquin '670 Another energy generating apparatus that harnesses energy from a fluid is shown in U.S. Patent No. 6,803,670, issued to Jean Peloquin on October 12, 2004 (hereinafter referred to as "Peloquin '670").
  • the apparatus of Peloquin '670 includes a tank for holding a fluid and having a bottom.
  • a conduit is in fluid communication with the tank for conveying the fluid into and out of the tank to raise or lower the fluid level in the tank.
  • a closed body that is buoyant in the fluid is disposed in the tank for moving in a vertical direction between an upper position and a lower position.
  • the body is mechanically connected to an energy transmitting device, shown as a rotating shaft, for receiving energy in response to the body moving between the upper and lower positions and for powering an electric generator.
  • an energy transmitting device shown as a rotating shaft
  • the tank of the Peloquin '670 apparatus fills with water, and the buoyant body rises upwardly to the upper position. Once the body reaches the upper position, the tank is drained, and the energy from the falling body is harnessed through a clutch mechanism and a tether member.
  • the Peloquin '670 apparatus While the Peloquin '670 apparatus is able to harness energy when the body falls downwardly from the upper position to the lower position, it is incapable of harnessing energy when the buoyant body is raising upwardly in the tank from the lower position to the upper position. This is because of the use of a tether and clutch mechanism and because buoyant body is weighted to maximize the return of energy during the falling movement. Any attempt at harnessing energy from the buoyant body when the body moves upwardly from the lower position to the upper position would either yield an insignificant amount of energy, if it yielded any energy at all.
  • the present invention is for an energy generating apparatus for converting energy from a body moving in both the downward direction from the upper position to the lower position and the upward direction from a lower position to an upper position.
  • the invention accomplishes this because the body is a container having an open interior for receiving the fluid from the tank when the container is in the upper position and for dispensing the fluid out into the tank when the container is in the lower position.
  • the container fills with fluid to increase its potential energy.
  • This potential energy is harnessed by an energy transmitting device when the tank is drained and the container falls downwardly from the upper position to the lower position.
  • the container discharges the fluid back into the tank to decrease the weight and increase the buoyancy of the container. This increased buoyancy of the container allows energy from the movement of the container from the lower position to the upper position to be harnessed by the energy transmitting device.
  • the energy generating apparatus of the present invention is significantly more efficient than the devices of the prior art because it is capable of harnessing energy from both directions of movement of the container. Only a very small amount of energy is required to fill and empty the container, and this small investment greatly increases the output of the energy generating apparatus.
  • the energy generating apparatus of the present invention can be powered with any type of liquid fluid from a wide variety of fluid sources including but not limited to a river, a tidal pool, a stream, a lock in a waterway, a water treatment plant, a sewage treatment plant or any other fluid source.
  • the present invention also has none of the disadvantages of other energy production methods. Speci fically, the present invention consumes no water and does not produce any emissions or byproducts of any kind other than usable energy.
  • FIG. 1 is a perspective view of a first exemplary embodiment of the energy generating apparatus

  • the inlet pipe 30 extends downwardly almost to the bottom 28 of the tank 26, but it should be appreciated that the inlet pipe 30 can be placed anywhere in or above the tank 26.
  • the inlet pipe 30 includes an inlet valve 32 having an open position for allowing the fluid 22 to flow into the tank 26 and a closed position to prevent fluid 22 from flowing from the fluid source 24 into the tank 26.
