The first install of the wind vane went well.  We have to profile the power output over the next month or so.  It has been ten months since we designed and made the first molds.  Alway nice to see an idea changed into reality.

The wind vane weights less than one hundred pounds.  It sits on a tapered roller bearing.  The top and bottom shaft is placed in a bearing block.  The drive shaft is 3/4 inch steel.  I can rotate the vane with a small force from one finger.


In the background you can see the three thousand gallon water tank that will be filled by using an air powered well pump.  A two stage air pump will be attached to the drive shaft from the wind vane.  The compressed air will be stored in a 500 gallon air tank.  When the water level in the tank drops then the well pump will turn on to resupply the water from the ground.  The water in this case is around 300 feet down.  The water is pumped up in stages that are 100 feet apart.  This keeps the air pressure to around 60 PSI.  It also allows for quick decompression cycles.  In time I will describe the design of the water pump so those who wish to make their own will be able to.  In time I think we will be making a lot of these wind vanes.  The one pictured here has all of the parts fiberglassed together but the next design will bolt together.  Many of the features made in this design will be incorporated into the molds.  This will speed the assembly and keep the cost down.

This company is dedicated to supplying water solutions that will survive natural and man made events such as solar storms or nuclear EMP pulses.  The systems are also off grid so you can enjoy the energy of the wind or solar doing the work.  We also will not design our systems with high tech devices so repair and maintenance can be done by just about anyone.

To power the water pump we have made a vertical wind vane.  If you wish the pump can also be powered by a solar panel and electric pump.  Our wind vane can be used for any number of designs and is sold separate.  The specs for the wind vane will be posted soon.  Right now we are making the first one.  It will be mounted and integrated into a water system. 

Our goal is to provide devices that will allow you to be self sufficient.  With just a few mechanical skills you will be able to maintain a reliable water supply for your family even in emergency conditions.

Integrated Wind and solar systems using low tech components

Vertical wind vane

To go with the air pumps that water72 has designed we have taken on a construction project that will use wind energy.  The wind  will supply power to a compressor.

The wind vane will also be connected to an electric generator.

The vertical wind vane project is being documented on our new projects page.  You can see pictures of the parts coming together.  You can get to the page by clicking this link.

Air Powered Well Pump

Water from 320 feet down

Water from 300 feet down.

The air powered pump has been around for some time.  But an inexpensive low volume pump is something we all should consider as a backup water system.  The energy to power the pump can be stored for decades with no maintenance.

In low volume environments the pump can be used as your primary well pump.  The low weight allows for DIY installation and maintenance.

The pump runs automatically when the air pressure is applied.  It has valves built into the controller that remain on the surface.  The pump supplies around 1.3 gallons per minute at 100 feet.  With inline pumps at 100 feet apart water can be pumped from 1000 feet down.  

The pump can be powered by a small compressor attached to a converted bicycle.  What is required is approximately 60 psi at 1 cubic feet per minute.  This will bring 1.3 gallons of water up from 100 feet down.  A well that is shallower will require less pressure.

wind vane ready for paint

The first wind vane is ready for paint.  We have to place the drive shaft into center and mount it on the roof.  The mounting poles are old drill pipe that we will weld brackets onto.  The bearing blocks are ready to be mounted on the cross members.  Cables will be attached to the pipe to keep them from bending in the wind.

Here you can see one of the two pipes that will hold the wind vane.  They are concreted in place and will extend up through the roof of the pump house.

The pump is not designed for a pressurized system.  The water needs to be pumped into a storage tank so the head pressure is as low as it can be.  This makes the energy required to move the water up the tube low.

We are designing a pressure pump for the water tank.  It will also be air powered.

air powered well pump, prototype

Here is a picture of me holding the first generation pump.  This was a test of the required air pressure to move water.  You can see the check valves built into the half inch tubing on the top and bottom of the design.

In an emergency if you manually turn a pump head to drive water out of the ground you want the system able to supply water with little effort.

Testing was done using a Dewalt air compressor with a 1.6 HP electric motor.  The compressor ran about 50% of the time when the pump was pumping water.  This means that approx .8 HP was used continuously.  That is approx what a man can put out in power.  So if you had to use your own strength to turn a compressor wheel you could supply the air pressure to supply your daily needs.  Our design goal was 90 gallons of water per hour.  Enough to supply the needs for your family.


Several years ago I came to realize that many people who think they are prepared for the grid going down or an EMP pulse only really have a temporary water solution.  I saw a need for an inexpensive well pump that operated on a power source immune from the effects of a solar flare or EMP pulse.  I knew that air pressure could be stored easily and made easily by rotary wind vanes or a solar panel and an electric compressor.  This site and products are the water solution I came up with.  It may not be perfect but it will keep you alive.  All of the parts are made of materials which do not make the water unsafe to drink.  Stainless steel, PVC,  and brass make up the main parts.

Everyone should have an emergency water backup plan.  A few gallons of water set aside is great but when it runs out you and everyone else will be searching for clean water.  Open water systems will quickly become contaminated.

In my study of people who prepare for disaster I came across what is known as preppers.  People who try and set aside food or equipment which in a disaster will help them or their neighbors.  We all rely on our technology and if it were to go away  we would lose our ability to survive.  Either exposure, lack of water or food will cause us to wander about with millions of others seeking the necessities of life.

In order to be totally prepared we need to have a plan which supplies shelter, food, and water.  In a major disaster we need to be completely self sufficient with a continuous supply of energy, food, and water.  This is not easy to do.  To attempt to do this on your own will probably not work.  A group of people with the required skills and material will be needed for long term survival.  This site is dedicated to one part of a survival plan.  I will talk about my plans and my systems but I make no guarantee that what I do will work in all environments.  It is best that each of you form your own plans and test all of the systems.  An emergency is not the time to dust off a pile of stuff in the garage to see if it will help you survive.

Please send me any suggestions on survival systems and I will post the ones I think make sense.

This site deals with well pumps, emergency water systems, Preppers, air pump, safe water, EMP issues, Nuclear bomb survival, clean water, Solar flare issues, solar flare 1859, solar flare 1989 Canada, fires caused by electric fields, EMP pulses, emergency survival, Air pressure, inexpensive well pump, cheap well pump, small budget, well case, well cap, solar panals, wind energy, turbine blades, fan blades, electric generation, and many more things.

We at water72 are dedicated to supplying all of the key components so you can safely obtain water in an off grid environment.  The vertical wind vane and solar panel chargers are part of those solutions.  Low tech battery charging controllers are also part of the system we will offer. The systems are made to use renewable sources.  So you could call then green energy systems.  Right now we are projecting that our vertical wind vane will output two horsepower in a stiff wind.  Here in the White Mountains of Arizona a stiff wind is easy to come across.
