Not this thing again. Nuclear batteries have been around for decades, it’s nothing new although it makes the rounds in the media for some reason every now and again. Yes they last a long time in theory, in practice there isn’t really an environment they can live for that long in. It just means the lifetime isn’t limited by the amount of energy the battery can provide and the failure mode will be something else. The thing that always gets buried in the media is the kicker: These devices produce at maximum a couple of nanowatts. That’s just about enough to lift an ants dick if you are lucky. These devices do have their own very niche and specific uses, however for the general public there is zero uses. And don’t go shouting but what if they scale it up or they are going to make it much more powerful. They won’t, that’s not possible and they are frankly very shitty batteries in terms of just about any metric you can throw at them. Their only real upside is the extremely long lifespan.

Yes these things are pretty neat and very interesting technology. No they do not serve any real purpose for the general public, so I have no idea why the media always wants to run with stories like these. It isn’t really helpful tech startups like Betavolt for example shout out nonsense to get funding and the media just takes their word at face value, even when what they claim is physically impossible and not backed up by even their own numbers in any way. This article is about an US based startup that uses the exact same tech and tries to make the exact same sort of noise.
