Electric desalination

[mtumut]

I am researching ways to desalinate sea water at sea with electric. I am not good at this subject but this could be electrolysis may be.
Please share with me your knowledge.
It must be adapted to 1 meter boat for Istanbul to Chile voyage , 1 liter daily.

Thank you ,

Istanbul

Mustafa,
it is spoken like Chile, but you write it "Sile"! And you can go there by Bus, no boat needed!

One litre a day is not much to go on. Are you sure you have this thought out in sufficient detail?
A reverse osmosis watermaker (pretty much the only type commonly seen on pleasure craft) will run you a few thousand dollars. I've never seen any cheaper systems that look like they'd actually work for very long (ignoring, for the moment, the little hand-pumped emergency units used for life rafts).

Matt, have a look here:

No food,no water,no sail,no radio/Currents,planktons,sun

mtumut, Why not a solar desalinator? No electricity needed, just a collector for condensation of evaporated sea water.

P.S., Isn't 1 meter a little short?

[mtumut]

There will be no sun where I am going only grey clouds I think. I will be at South Atlantic at the future exactly. I had been read a article about using aluminium plates and some other metals as anode and cathode.
It was saying it was possible to produce water.
OK. Let s be clear.
I dont know but which metals are suitable to electrolysis the seawater ?
Is it possible to clean the metals from collecting salt and other metals ?
How much electricity does it need to produce 1 liters of water ?
I can buy a Survivor 06 but I cant trust it. I need to find a way to produce my electric and water and food by myself with rock solid way.
I am searching for non moving parts technologies.
1 meter boat is little bit short but I will sit diagonal , it will make 125 , leg lenght.

So it really is 1 m, I thought for a moment there was a typo....
Electrolyzing seawater does not produce fresh water. It produces chlorine gas, some hydrogen gas, a little bit of molecular oxygen and a bunch of sodium and calcium oxides suspended in a slightly less salty seawater.
Where would you get electricity on such a boat, anyway? It doesn't sound like there's enough room for a person and food, let alone batteries.

3 square meters of piezo electric film costs 200 dollars. I am thinking to cover the entire boat with it and produce electricity with wind wave pressure.
There will be no battery but a chinese generator at the keel. I am thinking to cover the sail with piezo film also with one side flexible solar cell . I think kynar is lot cheaper at china , many many times cheaper. I will have a wind generator also. I will build the wind generator by myself.
When I started to research these , I have had no money. Now I have money but I stucked in to build cheapest.
May be I first visit Ukranian Docks and Russia with my boat at Black Sea. May be I climb the Danube to North Sea.

Is it possible to filter these oxides ? I watched a tv show about clay filters ?

I guess this is the latest version of Banana Split, but I can't figure out where the camera might possibly be.

[hoytedow]

Wouldn't a teakettle, a condensation coil and a catch basin be simpler? Put it on a stove and that's all.

[hoytedow]

Mustafa,
So, where do we send the sympathy cards when this seemingly overloaded small boat flips? Minimum daily water intake is closer to 4 liters. I worry for your safety.

[FAST FRED]

There are survival style reverse osmosis setups where YOU pump and some water is filtered to drinkable.

Might be more reliable than a home brew electric gadget that still needs to be invented.

Oh no - this guy again! he reels us in every time.

Lets all send him ten dollars so he can escape whatever hell hole he is living in in a bit more style than a 1 metre coffin.
