Coin-sized nuclear 3V battery with 50-year lifespan enters mass production

Not sure who wrote this article knows what they are talking about (AI maybe?)

Compact yet powerful, the BV100 is about the size of a small coin and delivers a power output of 100 microwatts at 3 volts. While its current capacity is insufficient for high-energy devices like smartphones or laptops, Betavolt envisions applications combining multiple batteries to meet greater demands. The company plans to launch a more powerful one-watt version later this year, with uses ranging from consumer electronics to drones capable of flying continuously without recharging.

A drone that can run off 1 watt battery ?!! Try 10 watt for a tiny one.

It is highly resistant to extreme conditions, operating reliably in temperatures ranging from -60°C to +120°C without self-discharge or risks of fire or explosion.

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?"

Solar panels could be about to get much better at capturing sunlight

Helmholtz-Zentrum Berlin and her colleagues injected liquid piperazinium iodide i

When I read that I thought the article was a joke. Turns out there really is an chemical called piperazinium.

In all cases biggest challenge is thaving these chemicals stable enough to last for at least 20 years or so otherwise it won't be worth buying. 31% effecieny is nice but still longevity is a big factor.

Privacy-Friendly Security Cameras Recs

I saw an article before about a guy who reverse engineered the app and figured out default camera's admin password so probably possible but I think not worth the effort.

what I did was

  1. Installing the app
  2. Create a hotspot that provides no internet.
  3. Connect to that hotspot so now my phone has no internet
  4. Open tapo app and setup the camera
  5. Allow the camera to connect to the internetless hotspot to finish the setup and enable rtsp
  6. Uninstsll the app

What to buy?

I didn't try many printers / software to commend you recommendt one but I can say that I have used creality CR-10S and had 0 problems with it. I use Cura software because it supports Linux but it works on windows too
