Voyager 1 is 16 billion miles from Earth, still transmitting data. Its power source has been running for 48 years. Voyager is kept alive by a single isotope. 4.5 kilograms of plutonium-238 sits inside a thermoelectric generator. As the isotope decays, it produces heat. 312 silicon-germanium thermocouples convert that heat into electricity. The generator has no moving parts. Hot side at 1,000°C, cold side at 300°C. 470 watts at launch from that temperature gap. The generator is 93.5% inefficient. That inefficiency is what keeps the spacecraft from freezing at -270°C. Power has decayed from 470 watts to 220 since launch. Engineers have shut down 8 of its 10 instruments to squeeze a few more years of data out of interstellar space. Starting in the 1970s over 2,000 plutonium-powered pacemakers went into human chests. Now researchers are replacing plutonium with carbon-14 in synthetic diamond. Carbon-14 only emits beta radiation and the diamond blocks all of it. A 5,700-year battery safe enough to hold in your hand.
