So the first problem is that power output is very low.
But the second problem is worse:
You cannot turn this power source off.
At 7% efficiency, if you had a 1W battery, it would dissipate somewhere around 13W of heat. If your smartphone needs 5W then it would dissipate somewhere around 65W of heat. Constantly.
Radioactive decay doesn't turn off.
- scotty79 6y agoNot a problem in this case because those batteries are less than miliwatt in a pretty macroscopic package.
- bcatanzaro 6y agoYeah. I'm just pointing out that if you tried to scale this to useful power amounts, the waste heat would be overwhelming.
