The mission was possible because it drew its power from two long-lasting radioisotope thermoelectric generators provided by the Department of Energy.
A thermoelectric material must allow electrons to flow freely, so they can carry away heat energy.
The new design is an improvement over current thermoelectric devices used for the generation of electricity aboard spacecraft.
Two potential solutions are thermoelectric power, which converts heat energy into electricity; and alpha-voltaic power, which converts the kinetic energy of alpha particles emitted from a radioactive isotope.
This equilibrium is reached through simultaneous application of active thermoelectric pulse heating and cooling gases.
Eventually, thermoelectric components might power cell phones by taking advantage of a person's body heat.
These portable thermoelectric generators contain a sizable amount of strontium-90, a highly potent radioactive isotope.
The second, Prof. Holger Kleinke, is investigating new thermoelectric materials in order to create energy-efficient cooling materials and power generators.
Besides the highly polluting thermoelectric plants, two environmentally friendly plants (acquired in Japan and England) have been working for several years, a fact not recorded in the book.
The Voyagers were equipped with three radioisotope thermoelectric generators to produce electrical power for the spacecrafts' systems and instruments.
