Abstract

This disclosure provides an apparatus for a portable thermal power station and related methods. The power station includes a burner, a reservoir, an output power plug, and a thermoelectric generator. The burner produces combustible heat across a surface. The reservoir stores a cooling fluid. The output power plug electrically connects to an external device. The thermoelectric generator receives heat energy, converts the heat energy to electrical energy, outputs the converted electrical energy to the external device, and disperses excess heat energy to the reservoir.

First claim

What is claimed is:

1. A power station used with a fuel container and an external device, the power station comprising:
a fuel connection for the fuel container;
a fuel regulator located after the fuel connection on a fuel supply path and configured to reduce a pressure of fuel from the fuel container;
a fuel solenoid located on the fuel supply path after the fuel regulator and configured to control a flow of the fuel from the fuel container to the burner;
a controller configured to control, using the fuel solenoid, the flow of the fuel based on an operating status;
a burner configured to produce combustible heat across a surface;
a reservoir configured to store a cooling fluid;
an output power plug configured to electrically connect to the external device; and
a thermoelectric generator structured with a supply side, a waste side and a power output and configured to convert heat energy into electrical energy,
wherein the supply side is directed towards the surface of the burner and receives the heat energy from the combustible heat of the burner, the waste side contacts the reservoir and disperses heat energy into the cooling fluid, and the power output outputs the converted electrical energy through the output power plug to power the external device.

2. The power station of claim 1 , wherein the thermoelectric generator is a sole power supply for the output power plug.

3. The power station of claim 1 , further comprising:
a cooling fluid pump configured to circulate the cooling fluid from the reservoir.

4. The power station of claim 1 , further comprising:
an evaporator including a fill material to remove heat from the cooling fluid as the cooling fluid circulates.

5. The power station of claim 1 , further comprising:
a fan configured to generate an air current to remove heat from the cooling fluid as the cooling fluid passes through an evaporator.

6. The power station of claim 1 , wherein the power station operates at a sound level below 50 decibels at full power generation of the thermoelectric generator.

7. The power station of claim 1 , further comprising:
an inverter configured to convert the electrical energy generated by the thermoelectric generator into an AC output at the output power plug.
