It works fine, but is too expensive for the small output. Maybe I should get rid of some of my videos? Most it puts out is 20-25 watts. In the same swept area for much less money I can get 75-100 watts with the newer lift types I play with.
I'm curious, what is the swept area and do you have a power curve or some idea? I have a fellow emailing me about this turbine/wants to build one. YOu talk about voltage at certain wind speeds, but not power.
No, I don't have a power curve that I have confidence in. It is 12 sqft. 4' high by 3' D. The most I have seen in watts is 30 watts going into a 12 vdc battery bank. For one thing I think this is too small to be really anything more than a trickle charger.
I am working on a larger model 6' High x 4' D which is 24 sqft.
Hello, iam from germany and i like your wind turbine design and like to build one for my garden, can you send me also the pdf drawings? Thank you very much
Great research! Have you thought about experimenting with the Tesla Turbine design within the interior of your turbine? I would love to see the effect of adding this to your design to increase RPM's.
Thanks for the sub. Yes I tried the tesla like discs inside the vanes. I believe that makes it more of a drag than lift design. I think it was a last ditch gimic for Tesnic turbines. The discs wont spin faster than wind speed. What we are after is lift.
Thanks! They are at a 45 degree angle from perpendicular to the axis. Flat side of airfoil faces inward, leading edge faces the direction of rotation. Why this works I haven't fully understood. I think because the wind is not moving in a straight line through the turbine, and the rotors move faster than the wind. I sail a lot and in that way it does make sense. Apparent wind is different than actual.
maybe it has to do with the outside of the structure effecting the wind into the middle faster. just a thought. I saw in the past 60 degrees used for vawt I was wondering what that was
the rotors moving faster than the wind is due to an effect called "apparent wind" there was actually a world record set in which a sail powered car went over 110 mph in only a 30 mph wind. basically this happens when u move "across" the wind.instead of just staying in the same place realtive to wind direction, the blades have the movement nessecary, and i think u got lucky with your design taking full advantage of it. that design with a gear would probably be able to make over 1200 watts
Originally I was going to use the magnetic levitation. The reason i didn't was that it would occupy several inches of space to support the 85 lbs of rotor. The rotor is made of two 3/4" discs, 16 blades and carries the 24 magnets and steel PMA discs.
As it is, the shaft sits on a single ball bearing and bears all that weight on a spot the size of a pencil lead.
wow that's a heavy turbine! you could've used the belt or the chain and do the ratio thing with the rotor in the motor(eg. when turbine makes one spin, rotor makes 40 full cycles), that way you could reduce the weight of the turbine by a weight of all the stuff on it...
Thanks! Its Murphy's law. Since getting the new rotor blades in, there has been little wind or an east wind which my house and trees shadow. The one day I did have 10 mph winds I ran a 50 watt 120 v halogen and watched the volts. No drop on voltage. The forecast calls for light east winds for awhile.
So far very unscientific. I am looking for best speed from the turbine and at least charging voltage. Easy to construct and affordable as a kit.
Speaking of electronics, your alternator and wiring looks very nice. It's so clean without wires twisted together and tangled in a big nest of knots and wire nuts.
It looks like a double rotor...12 mags, 9 coils?
How are you connecting the wires to the alternator?
That's funny because my twelve year old son suggested I clean it up more. So now there are three rectifiers on a heat sink, wires cut to length. And a cover for the top.
The alternator is 12 wedge magnets on each disk. The stator has 9 coils.
I am working on some simpler ways to make these. Each alternator took seven hours.
Can you tell me a good way to test this machine in a way that could be repeated by others? I'll test and report back. I have an rpm gauge, but not a wind meter.
The three phases are connected in "star". Three terminals are cast in the stator and are threaded with 10-32 bolts. Right now I am using this as a test bed so the rectifiers and inverter are mounted on the turbine. Ideally the ac would be run to where the rectifiers and batteries are and then the dc used.
I now have three rectifiers and smoothing capacitors installed.

WORLD RECORD: BIGGEST WIND TURBINE

ZERO-NOISE from gears and generators since they're sealed underground.
SAVES THE BIRDS AND BATS since the turbines are slow-moving.
DOES NOT NEED TO OCCUPY A WIDER LANDSCAPE since the turbine can be very tall.
MAY BE LOWER-COST since it can use parts of junked trucks and others.
ELUDES HURRICANE FORCE since the blades automatically close.
HELPS THE WIND ENERGY COMPANIES since it is FREE FOR ALL.

how do you get power from this turbine when the turbines arent touching the base do to the magnets?

Nice looking wind turbine!
Careful on your output. I heard you mention "100 watts". Nope...more like around 30-50 watts for that size turbine and that wind.
How are you determining the power?
Again, nice work.
