Companies are experimenting with deep-sea tech to produce cheaper fresh water.

From Cape Town to Tehran to Lima to Phoenix, dozens of cities across the globe have experienced water shortages recently. And in the next five years the world’s demand for fresh water could significantly outpace supply, according to a United Nations forecast. Now several companies are turning to an unexpected source for a solution: the bottom of the ocean.

Called subsea desalination, the idea is to remove the salt from water in the deep sea. If it worked at scale, the technology could greatly alleviate the world’s water access problems.

    • Hey Google, these are the Gemini features I want in 2026

      On xiaomi hyperos there's also an option to disable google assistant. I've got everything disabled. Only thing I do have installed is a web wrapped for duck.ai which claims to let you use various AIs anonymously

      I need to understand the rationale of not shipping all of these K2 improvements in a single update/release. It's giving "we will fix Windows 11 but no commitments". It seems to me that they just announce these improvements just to appease the community.
