A game changer watermaker if its as good as claimed.

There have been hand pumped desalinators on the market before, I contemplated putting one in a life raft once but didn't it relied on being squeezed.
To get that 2 L/Hr requires constant pumping at a fair old rate. It would be a case of needs must. If you were doing that work you would probably need a litre of the water to stop dehydration.

Artic pilot beat me too it.

It’s certainly a job for the cabin boy but why would you have him in your life raft?
 
Call me a cynic, but the whole thing has a hint of scam about it. To start with, it's improbably cheap at £48, but then they have the "buy one, we'll donate one" pledge, so the price is actually £24. The offer is designed to appeal to the "woke" generation. All the talk of 2.2 billion people without access to fresh water - but they mostly don't have access to reasonably clean seawater either, and that's all the QuenchSea can work with. Then there's the "spread the word and earn 7% commission on what your friends spend" offer. I'll be surprised if this one is a game changer.

Alright I will: you are a cynic and I feel sorry for you.
 
Maybe this shows that existing watermakers are overpriced? ?

The £48 won’t be the final retail price anyway. There are a limited number at that price. Yes one is being donated too, but that doesn’t mean it’s £24 each. The donated will will be at cost price for the manufacturer.
 
Some time ago there was a low cost propeller towed water maker that never worked and was discussed here.

The real issue is the lack of knowledge of the science and engineering required for a proper watermaker that really works.

It is too easy to make claims that are not independently substatented at a too lower cost to attract those who don't understand the science

Fair enough. I don’t have any need for a water maker at any price point, if I did then I’d take a punt on it at that price. Which is rather the point of crowd-funding. Getting a substantial number of units out to your target market even though you might not make a profit on those initial units can have benefits, especially if the product does meet expectations. Many crowd-funded projects don’t deliver as promised; I guess we’ll just have to wait and see with this one.

If you have arms and wrists like a silverback gorilla they might be useful.

Or a solar panel and a bilge pump motor.

Also, they say it will produce water with a TDS of less than 1000. So a reading of 998 is okay, or is it? I thought the current WM produce water with a TDS in the low hundreds.

Quenchsea is just chineese shit. Out of box needed repair and completely broken after 6 liters... Good that there was the Katadyn Survivor-06 in the grabpack to add some fresh water to our reserves every day...

Yes, I remember that. The guy behind the idea got very upset when people questioned it and some offered to review it. I think the mods shut down any further discussion. Never heard anything more about the device elsewhere either.
Came across another start up a while back for a water maker that used the pressure of seawater at depth. Basically, a flask with a membrane on a long spool of fishing line. Lower it to sufficient depth and water pressure did the work. Is it still around?

The Quench Sea Reel? Made by the same people as the hand pump desalinator which has been mentioned elsewhere in this thread. Looks as if it has not yet shipped. QuenchSea Reel
