Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Even if this would work without any complications from increasing atmospheric pressure, electrolyzing 0.5% of the ocean with present-day technology would take more than 200,000 years. That's plenty of time to invent new tech to speed it up, but even if some miracle invention next week sped it up by 2 orders of magnitude, it would still take more than 2000 years. So in feasibility terms I would rate this concept lower than building space elevators to save rocket fuel.
Cool sci-fi concept tho - let's get Arnold on it right away!
