Thermogenerators are devices which convert heat (temperature differences) directly into electrical energy. For the most part, this term is synonymous with "thermoelectric generator" and rarely used in English. The thermoelectric effect is the direct conversion of temperature differences to electric Voltage and vice versa They most commonly work on the principle of the Seebeck effect, with typical efficiencies of around 5-10%. The thermoelectric effect is the direct conversion of temperature differences to electric Voltage and vice versa Older Seebeck-based devices used bimetallic junctions and were bulky while more recent devices use semiconductor p-n junctions and can have thicknesses in the millimeter range. A p-n junction is a junction formed by combining P-type and N-type Semiconductors together in very close contact These are solid state devices and unlike dynamos have no moving parts other than sometimes a fan. A dynamo, originally another name for an Electrical generator, now means a generator that produces Direct current with the use of a commutator. Fuel such as natural gas, propane or kerosene can thus be used to generate DC electricity, which can be converted to AC by an inverter. Fuel is any material that is burned or altered in order to obtain energy Natural gas is a Gaseous Fossil fuel consisting primarily of Methane but including significant quantities of Ethane, Propane, Propane is a three- Carbon Alkane, normally a gas but compressible to a liquid that is transportable Kerosene, sometimes spelled kerosine in scientific and industrial usage is a Combustible Hydrocarbon liquid
