Google "ram pump" for all the details of this. The only drawback of the common design is that it pumps a portion of the source water, which can be problematic for drinking water supply, since the source is usually a surface source such as a stream or river. Using the large volume of surface water to pump a small volume of ground water source can be done through a variety of means, but it's more complicated.

This pendulum is not new, the Amish have used a similar device to pump water for years. Thier system uses a flow of say 1 cubic foot of water falling a distance of 1 foot - to elevate a much smaller volume uphill 40 feet as time is on thier side, periods of low water use slowly fills a storage tank in the attic so ample water at ample pressure is available during times of need. I am not going to waste time doing the math, but the energy equation in these devices is balanced.
