    Unless there is great leaps in the cost of Diesel, or greater efficiency in solar or wind power, I am not sure that the best idea for this is actually power generation, instead use it for your desalination units.

    There are major benfits for this. Clean water is very easily stored, and is something you will always need, on a good sun/wind day, you can fill your tanks for the bad days. I think this is a much better design concept then solar or wind power which generally requires battery banks if you want ot use it as a prime source of power. If your using the concept of condensing moisture in the air from pumping deep seawater, Windmill – pumping systems are mature, developed technology.

    actually there are many people that live on boats and get by with the electricity made from wind and solar power.

    instead use it for your desalination units.

    can split ocean water into oxyhydrogen fuel

    instead of having perishable battery-banks.

    we’ve known about hydrogen fuel cells for over a hundred years.

    in order to be effective at generating power from pumping deep sea water,

    have to have a pipe or tube at least 250 meters, preferably 500,

    so you’d have to have an oil-platform size installation,

    to make it reasonably proportioned,

    could cost millions or billions.

    solar-power nowadays has life expectancy of 20-25 years,

    so can be a reasonable long-term solution.

    it only costs $2.50 a watt nowadays.

    that’s 0.10 per watt per year.

    per watt

    with 12hr days, you get 12 watts a day, 4380 watts a year.

    if you had gotten those 4380 from an electric grid, it could cost you 44 cents.

    so really solar power is already more cost-effective than grid power.

    Not sure how you get the idea that solar is less expensive then grid power.

    Even according to the Solar people, your looking at about 30 cents a KwH (and this might be on the lowside), due to the fact the cell is not the only cost of a solar system and solar systems do not always have sunlight on them in the day. Grid costs per KwH is 8.32 where I live off the grid. In the UK your looking at about 11 cents per KwH. If you want to be self-suffencent on power generation, you can look at bio-desiel. However running a watermaker out of your solar or wind eliminates the entire “energy storage” costs, as you just run when you have wind/sun and store the resulting water in your water tanks that you already have.

    As long as you can have disel supplied at under 3 dollars a gallon, it will be cheaper to use desiel then solar on the sea-stead (and this is non-highway taxed fuel.) with current technology under my rough number crunching. Of course, both the cost of Solar and desiel are moving targets ;)
