    Water evaporation control in dams
    I have developed a product and process for control of water evaporation from dams. The quality of water also does not change and remains fit for human intake, agricultural use.
    This is new invention of its kind around the globe!
    I have to develop the prototype of the invention and produce material at pilot plant level.
    The invention also needs an international patent. For these I need financial assistance in the form of a fund. Then make it open to public.
    How is it possible to achieve the target and benefit the whole world?

    I can advise you that following research in USA and a practical trial in Australia (by others), I went to Australia and purchased a small device costing $Aus 400 (in 1972 values) for use in Botswana. The consumable was a mixture of two very cheap and easily obtainable semi-domestic products which were bought from a chemical company in UK.. The result was a monomolecular film sprayed on the surface of the reservoir every two weeks, or thereabouts. And a reduction in evaporation losses of (if my memory serves me right) better than 75%. Of course, the climate in Botswana was suitable, i.e. virtually no wind and very hot in the daytime.

    The idea was used in Botswana for some time (I left there after a couple of years so I am uncertain for how long they used the system) but it saved an expenditure of more than a US$million in building a higher dam. Like your idea, the chemicals were completely harmless to humans and animals (particularly cattle who drank from the margins of the reservoir). The idea was not patented, so far as I know, because it was thought better to leave it open for free use anywhere in the world.

    Best wishes,

    Good intention, wrong approach !
    This leaves open the way for anyone else to patent the product or application.
    It would be better to patent it, but not charge anything for it.

    Chemical monolayers for evaporation protection using fatty alcohols have been pantented in various forms over the past 20 years. Do your research to make sure you are not infringing
