Abstract

The Fluctuating temperature power generator uses variations in temperature to generate kinetic energy. Through mechanical means the kinetic energy can then be converted into electrical energy.

Description

Power Generator
Description
Background:
There are many forms of power generators in use at the moment, however none provide a safe constant source of useable energy. The Fluctuating Temperature Based Power Generator provides safe virtually limitless power by converting ambient heat energy into kinetic energy.
Advantages of the Fluctuating Temperature Based Power Generator (FTBPG): The FTBPG provides energy twenty-four hours a day without causing pollution of any type (no radiation, or toxic elements are generated). The FTBPG can be modified to work in any environment that has a fluctuating temperature, an environment that has a temperature source that is different from the ambient temperature, or an environment with two different temperatures readily available. The FTBPG can be used to convert desert land into a vast resource providing electricity at very low costs. The FTBPG can also convert heat energy from such materials as molten lava into usable energy. The FTBPG is not limited to hot environments, and can function in arctic or colder conditions so long as temperature variations exist.
For the purposes of this patent: cold means a temperature, which is cooler than the hottest temperature of the cylinder over the period of one cycle. Heat means a temperature, which is hotter than the coolest temperature of the cylinder over the period of one cycle.

The Fluctuating Temperature Based Power Generator functions by converting heat energy into kinetic energy.
Methods:
All the following methods convert thermal energy into kinetic energy (or useable forms of power), which can then be converted into electrical or any other type of energy.
Method 1.
A cylinder is filled with a medium that varies in pressure due to the temperature fluctuations of an environment. See Figure A.
Area 1. contains the fluctuating temperature medium.
Piston 2. Moves up as temperature increases, and down as temperature decreases.
Counterweight 3. resets Piston 2 to its bottom-most position when ambient temperature decreases
Gearbox 4. converts the movement of piston 2 into a rapidly rotating crankshaft
Crankshaft 5. provides useable kinetic energy
The energy from the rotating crankshaft can then be used directly as a kinetic energy source or converted into electricity.
Method 2. Uses a heat or cold temperature source to cause the fluctuating temperature medium to vary its temperature. The thermal energy is then converted into kinetic energy, which can then be converted into electrical energy. See Figure B.
Area 1. contains the fluctuating temperature medium.
Source 7. provides non-ambient temperature fluid who's flow to Tube 8 can be modified
Tube 8. connects the fluid from source 7. to 9.
External cylinder or coil 9. fluctuates the temperature of area l.'s medium.
Piston 2. moves up as temperature of the fluctuating temperature medium increases, and down as its temperature decreases.

Gearbox 4. converts the movement of piston 2 into a rapidly rotating crankshaft
Crankshaft 5. provides useable kinetic energy
Method 3. Uses a heat and a cold source to fluctuate the temperature of the fluctuating temperature medium. The thermal energy is then converted into kinetic energy, which can be further converted into electrical energy.
