    To quote from links:

    "it produces half a liter (17 fluid ounces) of water in an hour when subjected to hot and humid air. "

    "I finally achieved a constant drop-flow of one drop of condensed water per minute."

    I don't see you getting a half liter an hour in the southern ocean.
    Plus Peltier coolers are very energy intensive.
    I recommend more research before buying anything.
    Seems like I read a company called Global Cooling had a relatively efficient cooler that used the peltier effect, and Coleman sold them under their brand, but ceased to carry them some years ago I think.

    A local company contacted me,

    http://waterfromair.co.za/

    they are developing a small simple 12v compressor unit
    output 20 liters per day at a 3amp draw

    When I get more info I will post, but it does look interesting.

    That's cool. Imagine what could be done with desalination technology in order to limit damages of global warming or even prevent global warming by pumping fresh water from the ocean through gigantic pipelines into the deserts of the world.

    This is condensation units, small compressor like a fridge
    I think the best way to describe it is reverse refrigeration ???
    definitely not reverse osmosis desalination

    Condensation takes place when the air and condensation surface is a certain temperature apart. It may be easier to heat the air up by circulating it through a solar vacuum tube and using a small fan. The fan may even assist in keeping the condensation surface cool.

    I was going to build one but haven't yet.

    Since you have lots of sea water, if you use a solar tube you may generate drinking water through evaporation. If I fill a 1m800 x 58mm tube holding 2.5L of water, it boils itself dry in a day on a clear hot day.

    What worries me is you get sick if you drink sea water, but you can buy sea salt to put in your food.

    Will you still get sick if you make soup with sea water and drink that ?
    "Seawater contains salt. When humans drink seawater, their cells are thus taking in water and salt. While humans can safely ingest small amounts of salt, the salt content in seawater is much higher than what can be processed by the human body. Additionally, when we consume salt as part of our daily diets, we also drink liquids, which help to dilute the salt and keep it at a healthy level. Living cells do depend on sodium chloride (salt) to maintain the body’s chemical balances and reactions; however, too much sodium can be deadly.

    Human kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking seawater, you have to urinate more water than you drank. Eventually, you die of dehydration even as you become thirstier."

    It's from some government web site... can you trust it :D

    Big Day Today

    Well folks here are the pics I have been promising for ages.

    This has been an unbelievable amount of work.
    Back breaking, mind blowing, blood sweat and often tears.
    Many a day when you ask yourself why why why.

    Then you have a beer :D you sit back and look at it, and you know why,
    it's a boat - and a man has got to do what a man must do :D

    The steel ballast was completely encased in epoxy, you can see it in the one pic.
    The total hull thickness is 100 mm (4 x 20mm poly in 6 compartments)
    1000 liters of buoyancy
    and as she sits now she comes in at under 500 kg which is exactly what I was hoping for.

    I will make time next week for the blog and facebook
    but now it is time for the hand rails, hatches, rudder and swim platform.

    Oh - the 24v 1.1kw 86 lbs thrust Newport trolling motor IS GREAT it pushes Fargo easily at 4 knots. All I need to get in and out of the harbour.
