Summary

Diagram of the Inner Heat Source Unit (shown in packed form), the central part of the three <a href="https://en.wikipedia.org/wiki/MHW-RTG" class="extiw" title="en:MHW-RTG">Radioisotope Thermoelectric Generators</a> (RTGs), included on the <a href="https://en.wikipedia.org/wiki/Voyager_1" class="extiw" title="en:Voyager 1">Voyager 1</a> and <a href="https://en.wikipedia.org/wiki/Voyager_2" class="extiw" title="en:Voyager 2">Voyager 2</a> spacecraft.
It contains 24 pressed plutonium-238 oxide spheres, generating about 2400 Watts of thermal power at launch time - which is the decay heat of the plutonium. Outside are placed are 312 silicon-germanium (SiGe) thermoelectric couples, which are used to produce about 470 watts of electric power (at launch time), the remainder being dissipated as waste heat.
