True but that's at 5c. What happens if we go to 10c differential? Is the gain linear or does it become more productive as the differential gets higher? A radio

A radioactive device that gives off that much heat wouldn't make sense for something like your TV remote control. However, maybe it could help power your off-the-grid house.
Does a radioactive material exist that could give off a few Celsius degrees of heat for years?
Would it be feasible to have homes use that material (properly shielded) without being a threat to national security and safety?
- okket 8y agoIt's a whole subtopic with uses in satellites too far away from the sun (Voyager), or rovers on surfaces where they don't see the sun constantly / to much atmospheric interference (Curiosity). But I guess there are many more, just not for your wristwatch or your home. https://en.wikipedia.org/wiki/Atomic_battery https://en.wikipedia.org/wiki/Atomic_battery

No - the "hotness" is pretty much intrinsically unsafe, people can break into the shielding, and if you limit it to easily containable alpha emission it has a short life.
