A comment on NASA plans to launch a spacecraft to Titan. Parent comment
radio-isotope decay -> heat -> Peltier stack -> electricity.
Advantages: no moving parts, no vibration, infinitesimal mass change, exceedingly reliable. 'Small'
Disadvantage: Efficiency kinda crummy at ~5%. Slowly loses output as fuel decays and the Peltier stack degrades.
