This is a most excellent place for technology news and articles.
Article doesn't mention what the unit does with the salt waste.
I support this 100%, but desalination presents a unique problem: what do we do with all the salt? Maybe the unit uses it for something, but otherwise it just miniaturizes a problem that we're already working on.
If this works, it's better than anything we have , which costs grid energy and dumps brine all the same. If anything, the smaller scale makes it easier to distribute and dilute the output brine.
If sea levels rise as much as they're supposed to, this will be an invaluable tool for an enormous proportion of the country. My concern comes from capitalism getting its hooks into this.
Evaporate it to solid, store it if need be, or distribute it back into the sea in absorbable chunks. The water's ending up back in the sea eventually anyway, see water cycle, so it should be zero sum, just need to avoid local overloads. Seems eminently solvable.
Depending on the desalination method, you can also harvest lithium while your at it.
Sounds so easy for you but what to do with the excess salt is the only real problem with desalination that we have for decades now. It's not easy to solve.
Don’t you just dump it back in the sea? Diluting should make this a minor issue right?
That's what I always thought, but the local effects of hypersalinated water can be terrible for any nearby life
This sounds fantastic on its face, but I seem to keep on hearing about how desalination will solve all kinds of problems and we still have this particular problem.
The missing piece, it seems, is the will for it to be used as infra at scale. Meanwhile selling bottled water taken for free from public lands for several dollars a liter in single-use bottles remains a multi-billion dollar industry. (an industry, I might add, that is aggressive about lobbying to protect its interests)
Devices like this are a lifeline for communities in developing nations. Who are the first and worst affected by water shortages and salt water intrusions into their fresh water sources.
Also the poorest and least likely to get the help from the people with the resources to help.
cool, but the real cost of desalination is transporting the desalinated water upstream, which presumably would also need to be done here
Considering how many people live near the coast it would still be a huge step forward. Right now even for most coastal cities desalination isn't cost effective and they have to import water from inland.
And by not having to deliver as much water from inland to the coast that water can be distributed more for people living inland.
Yes, it's not going to make inhospitable areas liveable but it's not just "cool".
True...otherwise it's reverse hydro, which could be done with surplus renewables at peak times, but not at more than 10km.. This is mostly aimed at coastal communities (and sustainable floating villages 😁)
...or you could say fuck it, go full Dutch and build wind turbines and reservoirs everywhere to get water to all crops and green deserts 😊.
Since this produces distilled water, I imagine you could use it to filter any water, not just saltwater. You'd still need to boil it to make sure it was free of pathogens, in either case, and add an appropriate amount of salts and minerals back in to make it potable for the long term.
SONOFABIT*H, I've been working on a project exactly like this with my friend for a couple years. Hella congrats they got it done and working first but damn :'( I was too slow.
Imma go sadly crush some bugles with my face stones now
Keep doing it anyway. They still haven't gotten to market, and I want choices when it comes to my post apocalyptic water suitcases.
Zero reason to stop. Until this is put into practice it's just another article promising a future that isn't here.
All this stuff is like planning to colonize mars before we stop destroying earth. There is plenty of water if we just stop fucking pumping it all out and wasting it.
We're past the point where we can stop it wholesale.
We already have aquifers barely holding on, we've lost major sources of fresh water already.
I'm all for climate action, but we also need to starting developing technologies for living in the bed we've made.
Folks keep talking about climate change like it's some future event. You are living through it right now.
you know how we can stop the massive drain on the aquifers? by not allowing everyone to tap it as much as they want, farmers will have to deal with 30% fewer yields on corn, Nestle 'n Co. will lose their money printer, but that's all we would need to save the American aquifers, to STOP FARMING INT THE DESERT
All farmers growing cotton in the middle of the fucking desert along the colorado river basin disagree with you
Clean freshwater isn’t evenly distributed across the world and it’s not easy or cheap to transport. This kind of tech can help the people that will be most impacted by climate change to survive.
Can you believe some people actually drink that stuff straight from the tap? It's like they don't even care about the golf courses at all!
Where's the cheaper part?
It's just a giant plastic bag. They catch the runoff with a giant cup.
I feel like every week we hear about some huge breakthrough that is supposed to revolutionize clean drinking water technology and save the world, but nothing ever comes of it.
I know this stuff takes time to develop, and not every idea is going to work, but it would be nice if one of these things actually did pan out and start being useful to solve our drinking water issues.
Delete this before Nestle sees it.
