Origins & Early Life

A radioisotope thermoelectric generator (RTG, RITEG), or radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect. This type of generator has no moving parts and is ideal for deployment in remote and harsh environments for extended periods with no risk of parts wearing out or malfunctioning.

Career & Major Achievements

RTGs are usually the most desirable power source for unmaintained situations that need a few hundred watts (or less) of power for durations too long for fuel cells, batteries, or generators to provide economically, and in places where solar cells are not practical. RTGs have been used as power sources in satellites, space probes, and uncrewed remote facilities such as a series of lighthouses built by the Soviet Union inside the Arctic Circle.

Enduring Legacy & Impact

Safe use of RTGs requires containment of the radioisotopes long after the productive life of the unit. The expense of RTGs tends to limit their use to niche applications in rare or special situations.

Historical Fact-Check Quiz: Radioisotope thermoelectric generator

True or False: “RTGs are the most desirable power source for all remote applications because they have no moving parts and never require fuel.”

Answer (FALSE ❌): While RTGs are excellent for remote use due to their lack of moving parts, their high expense and the need for specialized radioactive containment limit their use to niche, rare, or special applications.
