The study tests a new battery made from sodium.
It charges twice as fast as today’s lithium batteries.
It lasts 3,000 charges before losing 20% of its power.
Sodium is cheaper and easier to find than lithium.
It is heavier, so it suits homes and buses more than phones.
It still needs testing at scale before anyone can sell it.
Your deck is ready. Pick a look:

Quiz me on the French Revolution.
Sure! Question 1: in what year did it start?
Private and direct
Nobody reading along. No filter on top.
Your chats stay on your computer.
Chats, files and images are made and kept on your machine. Nobody reads them, trains on them or sells them. Only web searches go out, and only if you turn Online on.
No filter on top.
Cloud AI runs your question past a company’s content policy. GreenCube adds no filter of its own over the answers.
Built to answer, not to refuse.
Its models are told to answer candidly. Swearing, dark fiction, blunt opinions, hard history and security research are all fair game.
Only real harm is off the table.
It won’t help anyone hurt people, exploit children, steal, or break into accounts. Everything else, you can ask.
How: GreenCube gives its models standing instructions to answer candidly. It steers them rather than retraining them, so now and then one can still say no. You can turn this off in Settings.
Your machine
See what can run on your machine.
Two things decide it: how much RAM, and whether you have a graphics card. Same app, same price either way.
Question 1 of 2
How much RAM does it have?
RAM, not storage. Not the hard drive or SSD space.
Question 2 of 2
What graphics card or chip?
Most laptops have no separate card, and that is completely fine.
How much it can read at onceA chat, a document, or both
About 3,000 words
About 12,000 words
About 12,000 to 25,000 words
50,000 words or more
Word counts are typical: they grow with how much memory your computer has free. Everything else is a starting point, not a lock (images need 12 GB RAM). Settings → What your computer can do switches each one on or off.
How it works
Three steps. That’s it.
1
Download it
One installer, like a game.
2
It gets the AI
The first time, it downloads the AI to your PC. A few GB, once.
3
Go
Chat, code, make images. Online or offline, as much as you want.
