A thermophone is a type of transducer that converts an electrical signal into heat , which then becomes sound. It can be thought of as a type of loudspeaker that uses heat fluctuations to produce sound, instead of mechanical vibration .
The basic principle of the thermophone has been known since the 19th century. [ 1 ... | https://en.wikipedia.org/wiki/Thermophone |
Thermophotonics (often abbreviated as TPX ) is a concept for generating usable power from heat which shares some features of thermophotovoltaic (TPV) power generation. Thermophotonics was first publicly proposed by solar photovoltaic researcher Martin Green in 2000. However, no TPX device is known to have been demonst... | https://en.wikipedia.org/wiki/Thermophotonics |
Thermophotovoltaic ( TPV ) energy conversion is a direct conversion process from heat to electricity via photons . A basic thermophotovoltaic system consists of a hot object emitting thermal radiation and a photovoltaic cell similar to a solar cell but tuned to the spectrum being emitted from the hot object.
