Very portable nuclear energy

Radioisotope Thermoelectric Generators, better known as RTGs, are systems that use a decaying nuclear material to produce electricity.

RTG's are physically hot in temperature, and reliable.

Radioisotope thermoelectric generators use a decaying nuclear material such as Plutonium. This material, as it decays, releases energy in the form of heat. A thermoelectric generator then uses this heat and converts it into usable electricity. The nuclear material in the RTG on the Mars Perseverance rover, Plutonium 238, has a half-life of 87.7 years. This means the nuclear material will not fully decay until 87.7 years - so this nuclear "battery" (the RTG) will last an outstanding 90 years until it is "dead". Any excess radiation released by them also can be stopped by a sheet of paper or your skin, so it's not dangerous.

Suitable for Mars Rovers, spacecraft, and more.

Various spacecraft and planetary rovers such as the Mars Perseverance Rover and the Mars Curiosity Rover use radioisotope thermoelectric generators. They do, primarily because solar power is not easily available on Mars, as dust often covers the solar panels, and Mars receives less sunlight as it is farther away from the Sun than our planet Earth is. RTGs are also a good option for spacecraft, as not all spacecraft stay within our solar system, and there is no solar power available outside of our solar system. Spacecraft like the two Voyagers use RTGs for long-lasting reliable electricity to power their systems.
