I looked it up, it’s around 50 000 liters.
So about 25,000 peoples minimum drinking water per day per bouy. Not too bad there.
Or the overall average water usage of ~13.2 people (went with the first number cause I ain’t researching things rn)
About 50 cubic meters. An Olympic-sized swimming pool is ~660,000 gallons, so it would take over 50 of them to produce that much water in a day.
As an engineer and lover of invention, I find the words “wave-powered desalinization” to be damn-near sexually arousing in their elegance and promise.
Slaps ocean; this baby practically desalinates itself!
Does anyone have a better source of info about this? I’ve found “good news” in the names of things to be a reliable indicator of people who seem to believe they’re trying to make the world better while polluting the information environment as much as any other fake news site. I’d rate the article as slightly less credible than a press release from the company itself.
The thing is that you probably won’t find anything that looks too closely at the efficacy of the claims, because the claims are all that anything is reporting on, since the product is so new. Here is a similar article published on asme.org (American Society of Mechanical Engineers), that discusses the buoys and the company’s claims surrounding them: https://www.asme.org/topics-resources/content/tapping-the-ocean
That is a really cool idea. We often think of renewable energy as electricity. But this bypasses that.
I hope it catches on, and is affordable.

Because nobody wants to sell this?
Because the people in a position to need to pay for desalination of their water are too poor for it to be profitable*
I’ll make as much as I can, and Nestle will buy every single drop.
Nestle should be encouraged to get their water from wave powered desalination

fishes better like a much saltier ocean
If the water cycle shuts down to such a degree that the desalinated water is not making it back into the oceans, we have planetary-scale problems far more worrisome than a slightly elevated ocean salinity.
If you had an absolutely huge number of these in a small area, I’m sure you could probably create a localized disturbance in the salinity. But 13k gallons is a pretty trivial amount. That’s a 50 meter cube of water per day… in the ocean.
With the rising sea levels due to glacial melt the saltiness of the water is going down, so really this is just doing the fish a solid! /s
Assuming:
Current ocean salinity = 35 kg / m3. Current ocean volume = 1.4 * 1018 m3. Current human fresh water usage = 4 * 109 m**3.(35 * 1.4 * 1018) / (1.4 * 1018 - 4 * 10**9).
= 35.0000001 kg / m**3. = New ocean salinity.
I think they’ll be okay.
Apologies double didn’t realize the double asterisks would screw up the formatting. 1.4 trillion trillion cubic meters ocean volume. 4 trillion cubic meters fresh water consumption
I get what you’re saying, but it’s not like we’re just taking that water and blasting it off into space. It’s going to be used and then make it’s way back into the ocean eventually. Either through evaporation and precipitation, or directly through rivers that feed into the ocean.
Of course, if there hasn’t been already, there should definitely be some extensive studies into whether there are any blockades as far as that water returning to the oceans in a reasonable amount of time.
