Thermo-electric engine
First Claim
1. A thermo-electric engine with a working fluid operative in a closed Rankine cycle to enable a harvesting energy from an external source of thermodynamic energy comprising the Sun, the thermo-electric engine comprising:
- a solar energy collector;
a turbine fluidically coupled to the solar energy collector for receiving working fluid from the solar energy collector wherein the turbine has a rotatably retained turbine shaft for being rotated by the working fluid;
a return conduit for returning working fluid to the solar energy collector from the turbine;
an alternator for converting a rotation of the turbine shaft to electrical energy wherein the alternator comprises a rotor, a plurality of magnets, and a stator and wherein the rotor, the plurality of magnets, and the stator are incorporated into the turbine and wherein the turbine has a turbine casing, wherein the stator is fixed relative to the turbine casing, and wherein the rotor is retained to rotate with the turbine shaft, wherein the plurality of magnets are retained by the rotor, wherein the stator retains a set of winding coils in proximity to the rotor, wherein the turbine casing has an end cap, wherein the end cap comprises the stator of the alternator, and wherein the winding coils are radially spaced on an inside face of the end cap.

Abstract
A thermo-electric engine with a working fluid operative in a closed Rankine cycle to enable a harvesting energy from an external source of thermodynamic energy, such as an internal combustion engine or solar energy. The thermo-electric engine can have an evaporator; a turbine fluidically coupled to the evaporator; a heat exchanger comprising a condenser for receiving working fluid from the turbine; a hot liquid input for coupling to a source of heated liquid coolant from an internal combustion engine to the evaporator; a liquid return for returning liquid coolant to the internal combustion engine; a cooling liquid input to the condenser for receiving cooling liquid from a radiator; and a cooling liquid return for returning the cooling liquid to the radiator. Alternatively, a solar energy collector can power a turbine fluidically coupled to the solar energy collector for receiving working fluid.
