This Is Red Button : Red Button Design.
This is a system developed by some students from Glasgow University. In it's present form it needs to be pulled by hand overland BUT I think a frame could easily be made that would allow it to be hung off the transom and have it turned by a paddle wheel
. I've written to them suggesting that there may be a side market for cruising yacht people needing a reverse osmosis
plant. Any profits could be ploughed back into the primary aim of bringing clean water
to the places where is just does not exist.
Would anyone like to comment on it's feasibility?
