Abstract
The invention is a converter for converting thermal energy into electrical energy. The energy conversion takes place by causing magnetic particles that are initially suspended in ferrofluid to circulate in the converter and to induce electric currents when they pass through one or more coils of electric wires that are coiled around parts of the conduits of the converter. The particles are caused to circulate around the main circuit of the converter by controlling the local temperature and pressure at different locations in the main circuit. The invention also is a method of using the converter to produce electricity.
Claims21
A converter for converting thermal energy into electrical energy by causing magnetic particles to circulate in said converter to induce electric current in one or more coils of electric wires, said converter comprising:
- a) A main circuit, comprising:
- a.1) A Heat Absorbing Container (HAC), having an inlet, connected to the first end of an inlet conduit, and a first outlet, connected to a first end of an outlet conduit;
- wherein said inlet conduit, said outlet conduit, and said HAC initially contain ferrofluid and carrier gas and said HAC is designed to absorb heat energy from an external heat source to heat said ferrofluid and said carrier gas to a first temperature (T1), at a first pressure (P1);
- a.2) An elongate Heat Dissipating Container (HDC) initially filled with ferrofluid and carrier gas, having an inlet, connected to the second end of said outlet conduit, and an outlet connected to the second end of said inlet conduit;
- wherein said HDC is designed to dissipate heat to an external heat sink, thereby cooling said ferrofluid and said carrier gas contained therein to a second temperature (T2), lower than T1, at a second pressure (P2);
- b) A reservoir container, connected by a conduit to the outlet of said HDC;
- said reservoir container designed to further cool the ferrofluid at the outlet of said HDC and to regulate the operating conditions in said converter such that the relationship between T1 and P1 remains within the desired range inside said HAC and said ferrofluid exits said HAC as ferrogas while passing from said HAC to said outlet conduit and such that the relationship between T2 and P2 assures full condensation of the ferrogas to ferrofluid at the outlet of said HDC;
- said regulation accomplished by allowing exchange of ferrofluid stored in said reservoir container with said main circuit such as to lower, or to raise, as required, the overall pressure in said main circuit;
- c) valves, for timely opening and closing said first outlet of said HAC and said outlet of said HDC and the inlet/outlet of said reservoir container;
- d) a first one-way valve, connected at said inlet of said HAC for allowing ferrofluid to flow only in a direction from said outlet of said HDC to the inlet of said HAC, as a result of the difference in pressure in said HAC and in said HDC;
- e) a second one-way valve, connected at said inlet of said HDC for allowing ferrogas to flow only in a direction from said first outlet of said HAC to the inlet of said HDC, as a result of the difference in pressure in said HAC and in said HDC;
- f) control means, for timely operating said valves;
- g) magnetic field generation elements, for generating magnetic fields around selected sections of said inlet conduit and said outlet conduit;
- said magnetic fields having direction and sufficient strength such that the individual magnetic fields of essentially all of said magnetic particles will be aligned by said generated fields when said particles move through said selected sections of said conduits;
- and
- h) electricity conducting wires, coiled around said selected sections of said inlet conduit and said outlet conduit, wherein electric current is induced in the coils of said wires by said aligned magnetic fields of said magnetic particles moving through said coils of said wires.
A method for converting thermal energy into electrical energy in a converter whose main circuit is initially filled with ferrofluid and carrier gas;
- said main circuit comprising:
- a) a Heat Absorbing Container (HAC), designed and located such that it is capable of absorbing heat from an external heat source, said HAC having an inlet, connected to the first end of an inlet conduit, and a first outlet, connected to a first end of an outlet conduit;
- b) an elongate Heat Dissipating Container (HDC), designed and located such that it is capable of dissipating heat to an external heat sink, said HDC having an inlet, connected to the second end of said outlet conduit, and an outlet connected to the second end of said inlet conduit;
- c) valves;
- d) Control means, for timely operating said valves;
- e) magnetic field generation elements, for generating magnetic fields around selected sections of the inlet conduit and the outlet conduit;
- said magnetic fields having sufficient strength and being orientated such that the individual magnetic fields of essentially all of the magnetic particles will be aligned by said generated fields when said particles move through said selected sections of said conduits;
- and
- f) electricity conducting wires, coiled around selected sections of said conduits;
- wherein, by controlling the local temperature and pressure at different locations in said main circuit, magnetic particles initially suspended in said ferrofluid will be made to circulate in a closed-loop in said main circuit, thereby inducing an electric current in the coils of said wires when the aligned magnetic fields of said magnetic particles move through said coils of said wires.
