Dear Mike,
What is great about the undershot waterwheel with the spiral pump, running a
turbine, is its scalability. It can be made as big as any river, ocean current,
or tide basin. Preliminary testing shows a about a 40% efficiency rate. This is
due to the ability of the spiral pump to create power at almost no RPM. Unlike
a mechanical system, you do not have to worry about what speed you have to
"gear" the system, since the Pressure Wheel will make maximum pressure with
almost no rotation.
I am at this moment talking to a power company. They are very interested in
developing the concept. Stay tuned!
-Dennis

Hi Dennis. Nice pump! Here is another commercial run-of-river spiral pump
that is designed for moving water for cattle or irrigation or whatever.

This pump comes in two sizes, but I do not think it can deliver enough to run
much more than nano-hydro.
