Nuclear Battery Practicality
Discussions focus on the feasibility, power output, energy harvesting potential, and applications of nuclear or betavoltaic batteries for low-power devices like IoT, with skepticism about scalability for meaningful energy production.

how practical is this, eg how big would a device have to be to produce any meaningful energy?
The important sentence: "It won't generate power".It's all fine to do this as a research project. But this is not a technology that is going to solve our energy problems any time soon - and it certainly shouldn't distract from deploying the solutions that exist today, aka mostly wind+solar.
I wonder why this isn't used to store power in a battery that's used for IoT devices?
Can you harvest energy from this somehow?
I wonder if this could be used for energy storage...
Which could be used for... heating? Lighting? Cooking? Cars? Something useful?
This is effectively a lightbulb that uses wireless energy.
Wait, isn't this all free energy, waiting to be harvested?
What is this trivial energy storage tech I've never heard of?
