Abstract

A portable combined heating and lighting unit comprising a first element and a second element for generating thermal or light energy, and a component to convert thermal or light energy into electricity. The first element generates thermal or light energy from combustion of fuel. The second element generates thermal or light energy from electricity.

Claims (13)

1. An apparatus comprising:

a lithium ion battery;

a portable room area heating unit, comprising an electrical device configured to use electrical energy from said lithium ion battery, wherein said electrical device comprises a resistive heating element configured to provide heat to an area outside of and adjacent to said apparatus;

an electrical inverter configured to convert direct current to alternating current;

a control system comprising control hardware and embedded software, said control system configured to automatically control the resistive heating element; and

a housing configured to house said portable heating unit, said lithium ion battery, said electrical inverter, and said control system.

2. The apparatus of claim 1 , further comprising a regulator configured to receive fuel from an associated fluid fuel source.

3. The apparatus of claim 2 , further comprising an air inlet disposed in said housing, and configured to admit air into said housing.

4. The apparatus of claim 3 , further comprising a burner region in fluid communication with said regulator and in fluid communication with said air inlet, said burner region configured to produce thermal energy by combustion of an air and fuel mixture.

5. The apparatus of claim 4 , further comprising a thermoelectric element configured to convert at least some of said thermal energy to produce electrical energy.

6. The apparatus of claim 5 , wherein said thermoelectric element comprises a BiTe alloy.

7. The apparatus of claim 1 , further comprising a portable light unit configured to use electrical energy from said lithium ion battery to provide light.

8. The apparatus of claim 1 , further comprising an electrical rectifier configured to convert alternating current to direct current.
