Not sure who wrote this article knows what they are talking about (AI maybe?)
A drone that can run off 1 watt battery ?!! Try 10 watt for a tiny one.
The battery relies on nuclear decay. Nuclear decay has fixed half life. the battery would be dead after the 50 years whether you used it or not so what does it mean "no self discharge?"

Tiny wattage, but still useful, especially if you can group these into larger battery packs

Haven't these been around for ages? All the heavy crypto servers I've worked with have had nuclear batteries because they kept keys in volatile memory, and the trickle current keeps the supply of power from being accidentally interrupted and dumping all the keys. Is it just the new form factor that's novel?

Higher power output, smaller form factor, cheaper manufacturing process and safer to handle

As radioactive decay can't be stopped, I'm assuming this emits power continuously. Whatever this is used for won't have any On/Off buttons.

You can probably turn the device off, but you won't save any battery.
