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. Period.
