Part 2 is now done and covers power generation: http://www.youtube.com/watch?v=24LSnATIZhw
Harness the wind for less than $100.
DIY vertical wind turbine of the Savonius style.
Notable is that this cost less than $100 in materials so far and that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy).
Also, this turns well in a very light wind.
Axle: 3 inch PVC piping from Home Depot
Bearings: 5 inch lazy suzan from Lowes.
Part 2 will cover power generation and connection to the battery bank.

They have now lasted for over a year and a half.
They do require lubrication about once a month. I am now using different bearings in my new turbines. (see my magnetic bearing video)
Those bearing are …
Those bearing are going to wear out quickly.
You need to see …
You need to see part 2. Yes, I use a gear. Making a pump handle go up and down requires a helical gear and a worm gear (search the internet for BAKER ZA HEAVY DUTY PUMP JACKS) to see one that works with an electric motor.
How do you pick up …
How do you pick up the energy off the rotating shaft? Do you have a gear around the shaft? Also, is there a good way to make turn the power 90 degrees so I could make a pump handle go up and down?

did you ever get this thing up to the proper amount of RPM to generate any kind of usable electricity?

This very interesting idea, I guess a question that should lead a pulley at the bottom of the boat, as couples in 2 feet of roller diameter and the pulley to be a permanent magnet generator.
Thanks for your desing.
No I actually like …
No I actually like and encourage the idea of building one yourself, Feel free to contact me if you need instructions on how to build your wind turbine. I’m glad that you liked my advice.

The noise problem …
The noise problem probably isn’t the bearings. The drum material, being light but rigid, amplifies every little vibration. The stiffening ribs or a fairly thin layer of ordinary foam or fiberglass insulation would dampen most of this.
BTW, I do think this is an innovative idea and suspect you may have a marketable product. The existing wind generators with long blades are also noisy, expensive, and in some installations, dangerous. Keep up the good work.
Are you talking …
Are you talking about putting insulation on the inside of the drums? If so what form of insulation? I think that with the new bearings I am using it will be nearly silent anyways.
How much heavier …
How much heavier would 1/2″ of fiberglass insulation make it? How much wind could that block? For that matter, a few stiffening ribs would work pretty well, too.
There is no ” …
There is no “Coriolis effect an anything smaller than weather systems. I have lived both north and south of the equator and have tested this myself on several occasions. The design of the toilet/bathtub/sink has far more effect. This has also been addressed on other sites and tested in laboratories around the world.
I am figuring this …
I am figuring this out now. I don’t have the data yet but am putting a hall effect sensor on the turbine to measure the average rpm, and just bought a usb connected weather station to cross correlate wind speed, electrical output and rpm. The rpm of the motor needs to be about 300 rpm to get 14 Volts.
No because it would …
No because it would either make it heavier or block the wind. I am working on a much quieter version of this now which uses sealed bearings.
I think this is …
I think this is probably not significant: “the Coriolis effect is too weak to be observed except under laboratory conditions.” (quoted from wikipedia toilet section)
I have a question. …
I have a question. Should vertical shaft windmills turn the same way as the water vortex in the toilet? How much energy is lost or gained by being in synch with the earth’s rotation? Thanks!
Could you add some …
Could you add some fiberglass insulation or something like carpeting to the inside to soften the noise? Those barrels, being thin plastic amplify every little rumble.
what is your …
what is your average rpms on your wind genarator.?
what is the rpms needed to get 12.5 volt min from your alternator? this will deternine your gear ratio for your gear teeth
