I was just watching a video on how desalination is energy intensive so I wondered why can't we just use the sun? The sun will evaporate water with ease so it would make sense to build a larger scale solution

That's pretty dope. I assume you could also distill drinking water from freshwater sources with this method? Maybe needs less layers? Also two ideas: 1) Extract electricity from the salt gradient at night. 2) Solar powered steam-boats. There has to be a size of boat where that's viable.

Freshwater? No just boil it and you should be fine. The main issue with drinking salt water was the salt, fresh water does not contain salt so it's not necessary

Graham, my friend, sorry! I thought we were discussing desalination and is application in the world of ever increasing problems. This has to do with science, politics and politics. The religious beliefs of one group of the world (to which I was raised as a Greek Orthodox) do not have a place in this discussion. If you want the religious aspect, God (or the Goddess or the Gods or the Spirits, as per one's beliefs) will want us to survive and go further on, so that's what we are discussing here (not 'Satan's' wishes.

this is very ingenious, I think need some refinement buy the whole idea is genial.

Could you provide the link to the research? At the end of the video you say there is a link to more information, but there is no link

"For more details check the link in the description section." That's what was said in the video. It isn't what is true though as there are no links in the description section, at all.

Where is the catch?!?

@kooshanjazayeri

11 ай бұрын

the catch is that if implemented in large scale it would make the ocean water too salty, but there are always ways to solve these kind of problems, very cheap solutions rarely work, but these are much cheaper solutions than what is currently used, and those ones just don't care much about "the catch" either

I'm working on an improved version of the solar still desalination process shown here at 1:36. The thing is I'm an amateur ... On the whole, solar desalination of seawater sounds extremely appealing, except that there is a 'small' catch - there always is one ... If everybody started using it, we'd end up with a whole lot of salt (about 4% of seawater is salt and minerals) and I've not found any mention of what we'll do with all the excess salt. To give a rough example (don't you quote me on it!): Let us assume that for every person on earth (say, 7,800,000,000 people) one cubic meter of seawater is desalinated per day. that gives us: 7,488,000,000 cubic meters of fresh water (wow!) which multiplied by 350 days per year (say, for rounding purposes or for maintenance reasons) results in 2,630,800,000,000 cubic meters of freshwater per year. Excellent! And the seawater level will only go down 7 mm (about 1/4 of an inch) worldwide - no problem, as it's rising anyway ... Yet, the unavoidable issue is that we'll be producing 312,000,000 cubic meters of salt per day or (by the same calculations as before) 109,200,000,000 cubic meters of salt per year. In 2020, the global consumption of salt was 335,000,000 metric tons (www.foodexecutive.com/en/marketing/2096-global-salt-consumption-raises.html) or 154,435,000 cubic meters (www.aqua-calc.com/calculate/weight-to-volume/substance/salt) or 1 over 700 what we would be producing - put in other words, just 1 year of this extensive global solar desalination project would cover the annual consumption of 700 years of salt!!! Now, I think I know the 'easy' answer: we dump the excess salt back in the sea where it came from ... Disastrous! That would totally ruin the ecosystems of enclosed seas (think of the Baltic, the Mediterranean, the Red Sea, the Black Sea, the Persian Gulf, the Caribbean and Hudson Bay, to name but a few) and it would increase the salinity of the seawater worldwide (salt is great in absorbing heat, so the seawater will get warmer, so the greenhouse effect will get more acute ...

These are small scale subsistence systems that do not increase salt concentration given the large volume of circulating water. It would be a different matter if this was done on an industrial scale indeed. You could probably shake up the towels before night time to retrieve part of the salt crystals, and maybe salt fish with it.

Small plants distributed all over the place would minimize the environmental impact. You could also build large plants far out in the ocean dead zones where the impact would be negligible and build pipelines to transport the water. It's only a problem if you do it by the coast since the most biodiversity is there and also less water to dilute the salt.
