I was watching with a friend a dvd from
Sepp Holzer and it was mentioned something about his water pumps not using electricity. Perhaps I misunderstood. What sort of pumps is he using to pump water up a hill? This seems to defy my logic.
We have a pond. It is about 20m (60') from a creek 4m (13') wide that we would like to consider as an alternative energy source. Most of the year the water flow is minimal and a small dog could hop across it, but during autumn and winter it is gushing. I am wondering what options there are, perhaps if we could use a pump to pump water into the pond like a water feature / mini water fall to oxygenate the pond and have fresh water flow.
Is this sort of thing possible without plugging into a power source?
Many thanks,
Rob
