A safe nuclear battery that could last a lifetime
Nuclear batteries generate power by harnessing high-energy particles emitted by radioactive materials. Not all radioactive elements emit radiation that’s damaging to living organisms, and some radiation can be blocked by certain materials. For example, beta particles (also known as beta rays) can be shielded with a thin sheet of aluminum, making betavoltaics a potentially safe choice for nuclear batteries.
The researchers produced a prototype betavoltaic battery with carbon-14, an unstable and radioactive form of carbon, called radiocarbon. “I decided to use a radioactive isotope of carbon because it generates only beta rays,” says In. Moreover, a by-product from nuclear power plants, radiocarbon is inexpensive, readily available and easy to recycle. And because radiocarbon degrades very slowly, a radiocarbon-powered battery could theoretically last for millennia.

I ditched my laptop for a pocketable mini PC and a pair of AR glasses — here’s what happened
My whole desk setup now easily fits into a backpack and I can take it anywhere
I’d actually wondered about a set up exactly like this. Looks like it could be a winner.
Although I don’t think I’d want to carry four things around with me (ie mini PC, glasses, keyboard and power bank). Maybe if the glasses take off generally then someone will sell keyboards with a battery. Or maybe laptops without a screen?

We could use that feature on this site.

I don’t think it covers cheating on your deal a meal plan.

Maybe not, but it will allow us to feign interest in half the conversations here.

Isn’t it good Maryland wood

@Tazz As I recall, the Germans have been doing some big projects in wood as well, just not to this scale, 1,000+ feet!

At least Maryland is good for something. Maybe all those assholes will leave my Virginia roads and go carve some wood steel shit or something?

I wonder if you could use it to make a veneer chair that is less than 2mm thick.
