Cool. Will probably be one of these things that the people who have something to lose from its development buy out - so that it never ends up being developed :evil: .

Some promising stuff there regarding pumps, but I wonder if the ripple thing would serve to add oxygen by breaking the surface tension of the water. Any hydrologists (sp?) here?

A coil pump will add O2 to water as it is pumped up hill. With a very low energy input.
