Welcome to WildWaterPower!
Shown below are my various forms of new hydro power. These hydro-power projects
have been the core of my site for many years.
I have decided to update this site with some of my side projects. I hope you enjoy
seeing them as much as I have in building them!
My first attempt at hydro-power was an overshot wheel design with a chain drive.
The wheel was made of 4X4's and the chain drive and components were purchased
through Grainger. This made it relatively cheap, but I found the design was
complicated. I decided to start over. I also decided to focus on a "run of the river"
system since at the time there were no products available for this market and there
were many more sites for this type of power generation than ones that requires a dam.
My second attempt was a Persian Waterwheel design which makes electricity, which
I call a Gravity Wheel. It lifted water to make head. But I was dissatisfied with it
since the head generated was limited by the hight of the wheel.
Then I started experimenting with attaching a Spiral Pump (an already known
technology) onto a undershot wheel to make pressurized water to spin a turbine. I
have determined that the design has great attributes for a large system, but for the
homeowner it will be a bit expensive due to the cost of the turbine.
My latest design will use a PVC wheel and frame; float on dock floats; and use a
welded chain as a large sprocket to get around the gearing issue.
I feel this new design will keep cost down, be strong, corrosion resistant and produce
decent power for a homeowner.
At this moment due to money issues I am putting off actually building a prototype

I found this one online. It is a spiral pump in its traditional
job, raising water. I think it is about six foot tall (the site does
not say), and raises 16 l/min up to 25m ht. That is a lot of
pressure to lift that high. Even though it is very crude, is not
floating (one has to wonder what happens when the big flood
comes) it is the largest, heavy duty spiral pump I have found.
If this was mine I would fit it to not only raise water but also
produce electricity. It gives an indication of what is possible.
One day I would like to think of this as small.
CHAIN DRIVE OVERSHOT WATERWHEEL- This
was my first water power project. It is nine foot in diameter, five foot wide
and produces 1500 watts with approximately 1000 gallons per minute. The
chain drive is much more complex than a spiral pump setup. The wheel itself
is great, it is made of 4x4's and used plastic buckets.
Spiral Pump Sites!!!!
This is my latest work. It has 400 foot of 3/4 hose and makes 50 PSI
with the spiral pump plugged. I am currently working on prototyping
new paddles. With the spiral pump I am looking to run the wheel very
slowly and generate high pressure. With this model in mind, I am
making paddles with vanes to increase the impact area, decrease the
turbulence created. In many respects I am trying to copy the
efficiency of a turbine blade on my paddles.
This is the prototype put together by Mark in Canada. It
floats, pumps 2.5 gallons a minute and maintains a
pressure of 45 PSI. It provides grey water to his cabin
and here it is making 6 Watts. We should be able to get
much more power, but the bladeless turbine which he
had been experimenting with is a disappointment.
Until a much bigger version is built it is not
economically practical to buy a turbine and air motor to
produce electric power.
Here is a great illustration. It clearly shows how the
columns of fluid build on one another and how the
rotation of the wheel and the Spiral pump work in
counter directions. The air compresses and allows the
pressure of the columns to build on one another.
Notice the air going out of the lift pipe. It provides
buoyancy and lifts the water higher than the pressure
Gravity Wheel-converts the flow of a river into water pressure by lifting the
water; thus creating head. It acts as a huge transformer, changing high
volume-low pressure into low volume-high pressure. The problem with
this design is the head created is limited to the size of the wheel itself.

Paddle experiment. By making blades
out of PVC I am trying to create a
much larger surface area for the
water to push against, while
My first test bed for the Spiral pump. The all PVC wheel made
me a believer in using PVC for water power. It is one spiral
pump distributed between both sides for balance. It makes
between 30-35 PSI. It is an enclosed system, the fluid goes from
the reservoir, through the spiral pump and then back again. I
use this as a proof of concept prop now.
Mark has passed on. I would like to dedicate this site to his memory. He was a much greater
technologist than me and his presence in my life will be sorely missed.

Spiral Pump Videos On Youtube
Two teams of student engineers at Robert Gordon University approached me for some help in
using a spiral pump to enter into an engineering competition. The competition was to design
something to pump water and shoot it as high as possible. Flow into pressure.
They came First and second!
