Hi, I'm in Australia. We have been using 'wind generators' for over 100 yrs. We have tried a lot of designs to improve the old "Dunlite Windgenerator". What your doing is bloody awesome, keep it going.

[@thebytespider]

Really like this wind turbine, it reminds me of a pin-wheel. I could totally see a couple of these in the garden to power garden lights

I think it would work superbly as a tidal turbine. The waistcoat- superb. Very nice handkerchief. Clothes befitting a gent and a scholar.

[@elvistesla3179]

You are exactly on track with what have thought for a long time. Golden ratio capture and conversion of the wind for most efficient processing of it and a way for excess pressure to mediate or pass through so as not to stress the the prop. Putting these in an array, minimize with magnetic bearing any resistance. Make them cheap, small, modular and easy to replace. Cost effective wind conversion anywhere to get the ROI right up asap.

I'd love to see an Archimedes turbine mounted vertically inside a Darwin turbine. They look like they were made for eachother.

[@bohabdestructo7489]

That was my first thought. It looks like it would be very efficient.

[@ebaab9913]

I also saw these as a match made in heaven 😊. Also because it would allow the use of the ball bearing tip to get low friction. One thing I have found which is very important, is that these Neobidium magnets do not like being outside. If the surface coating is even very lightly scratched, the magnet just turns to rust dust.

Hey, thank you for doing it with two sets of magnets! That’s quite a lot of energy you’ve got there!! Congrats on this awesome channel!

[@TAMESoftwareInc]

Do You know why ship propellers aren't shaped like an Archimedes Screw? Because it was found that if you cut the screw off at a point where the top of one blade starts to cover the bottom of the other, it's more efficient. It's a simple optimization that's been known for over a hundred years now. I bet You'd find the same if You were to cut the height of the screw in half and just keep the wide base.

[@skampp]

That's a really nice build - maybe my favorite of your designs yet! I'm excited to see how it performs. I live in the southeastern US and my heat pump runs probably 9 hours a day on average at this time of year. I think I can make use of that exhaust air from the condenser fan, providing it's enough to collect and use in the shop.

[@azena.]

It's worthwhile considering that if you added this to the air pump exhaust flow, you might be effectively making the air thicker. I'm not sure how much excess there is in the fan, but it's possible you could cause the fan to need to work harder, or limit the heat input/output. Ultimately, conservation of energy, and I don't know how that would impact that kind of setup, it might be negligible though, in which case that could be an inventive way to net increase efficiency. Not sure how you'd test it. You'd need an isolated system with effective ambient temperature control and then attempt to see what kind of temp differential you could create for some unit input of power with the power harvested subtracted off.

[@skampp]

@@azena. Excellent point for sure. This is a typical fan though that blows vertical into the atmosphere with no restriction, not like in a pipe or constricted area. So if I covered it up with like 16 of them it might have an impact, but likely not noticeable with a couple. Good thinking, thank you.

[@azena.]

@@skampp Quite possibly, it's difficult to say without doing tests to verify. The impact of a couple may very well be negligible, but then again who knows! I guess it also depends on the kind of environment the outdoor units are tested in. After all, they have to deal with wind from multiple directions, so actually, maybe there really is nothing to worry about. I can feel the variable list and unanswered questions growing 😂

The improved efficiency spiral wind turbine was already Patented in US by Japanese man in Texas, a long time ago. Large scale models also built. It's called Tornado turbine. Also, the late Mr. Baumgartner had built a lifting device platform utilizing the ETHER , by swirling of turbine air with high rpm motor, very low power , and lifting very heavy weights. (Extracting energy power from the ETHER through angle of NATURE'S spiral). He used computer program to get exacting design . Two-page article with photos was in an old Alternate Energy newspaper.

[@successfulengineer]

Hi Robert, a couple of questions pop up for me with every one of these generator videos ... Why do you always put the magnets on the outside (far away from the coils) ? Surely closer is better ? And second question is whether you align the opposite poles of the magnets on opposite sides of the coil ?

[@Stubby0266]

Is the spacer supposed to be loose in the coil former? I noticed in the video that there is a gray space? in the blue coil former. What keeps the coil from floppying around?

[@davidl.howser9707]

Robert, ☝️☝️✍♥️ maybe a series of forward facing funnel shaped shroud , then cylinder cover, and then tail components to first collect wind like an open funnel similar to what a dog wears after surgery, and add an interior rough surface or dimpled surfaced cylindrical wind energy concentrating housing shroud placed 360 degrees closely around the auger's length as a wind energy cylindrical concentrating surround to direct the wind energy to pass over the auger's fins in a parallel fashion and at a higher wind speed with the third component being that of a well set back trailing fin to turn the auger steady into the wind designed like the 1900's U.S. farmers type simple fined water pump wind prop with flat sheet tail. Think of a tail shaped like a boomerang so that the top and bottom surfaces of the trailing tail are out of the auger's vortice exhaust wind turbulence. Please keep up the inventing.

[@jeffwhite1457]

Robert, I enjoy your videos and I would love to see you build my idea. I envision a two foot metal rod with a large archimedes turbine on one end and a generator winding on the other end. There are magnets that create a mag lift to the rod and in the center of the rod there is a flywheel. The flywheel has holes drilled at a 75 degree angle that house magnets that generate a magnetic push once the wind starts the turbine spinning. Mounting it on a platform, would allow for adjustment and maximum wind capture. With the hand powered spin of the flywheel the turbine and magnets would increase the speed with very little resistance.

[@vinquinn]

Nice Construction. It spins well. It makes voltage. Put a little load on it and see what happens. Maybe you could get enough power to charge a phone. It needs to be much bigger to serve a useful purpose. I think a large one could be hooked to a hot water heater to get a little free hot water if you have enough wind.

Will a funnel shaped skirt at the rear smooth the vertices at the rear archimedes screw inprove the efficency and cut down on the vibrations and make the generator point into wind self steering ?

[@hansranz9525]

I would be interested on the efficiency of the different designs. If you have much wind, all would work and generate enough energy for privat cases, but mostly are low wind conditions with less energy inside. So its important to use the theoretical possible energy with low wind efficient. Sure it is not Trivial, but maybe you can test equal scales of your designs on a big ventilator with the same generator and measure the power output? Very nice work you do!

[@kezyka6775]

I think a bit of the wobble/unbalance is due to the spiral not being evenly distributed in weight. A way to counteract this without messing with balance weights would be to make it a double (or more) spiral. Fun video though :)

That's impressive just for the fact that the highest wind speed at 2m/s is around half of the minimum required wind speed for a 3 blade turbine

[@eXeYeZ-404]

Would a stack of magnet disks and coils make electrify? Or would having so many magnets and coils so close together cancel it all out. For instance 6 magnet disks with 5 coils between them rotated my a turbine/gears. It seems with enough torque to turn a large stack could be an answer to folks that have limited space.

[@JenkoRun]

That little turbine is just gorgeous, have you tried using capacitors in series to cancel the back-EMF generated in motors and the generator itself? Eliminating that little problem would be huge.

[@danedmiston9673]

The "back-EMF" is what makes it a generator, the more the better.

[@JenkoRun]

@@danedmiston9673 Have you experimentally verified that? Because that doesn't match what I've learned from studying Tesla and Steinmetz works, among others. The input torque of an electrical generator would free spin freely and indefinitely if not for 2 things, Friction and the Backwards Translation of Load in the form of a reverse magnetic field which forms as a result of the forward current, and which opposes the input motion. This reverse torque fighting the input torque requires more and more energy to be applied at the input to continue the ability for the extraction of energy at the output. Tesla spoke about this reverse current and reverse magnetic field, now called the Lenz Law. Tesla opposed the reverse torque natural occurrence, with the introduction of capacitors into an already inductive generator coil circuit. This is evident in the writing of Tesla's pancake coil patent. But more importantly he invented resonant electrical circuits, the resulting oscillations that occur within the same capacitive / inductive circuits, which alternately transmits magnetic and then dielectric pulses, over time, which each passing electrical half wave, and influence other similar circuits with the same electrical resonant frequency. The key here is that these secondary circuits are forced into electrical oscillation without a backwards translation of load, so long as the frequency remains perfect on both circuits. In other words, if you can keep the circuits resonating while you extract power from the second circuit, you will be able to withdraw more energy from the output than there is needed at the input to keep the system running. Then you can loop a portion of the output to power the input continuously and indefinitely. This has been successfully done and demonstrated in the work of Don Smith of Texas USA, and Tariel Kapanadze, of the soviet satellite country Georgia. The configuration is Tesla's patent 645576, System of Transmission of Electrical Energy. The configuration is Resonant circuits that are connected via the dielectric field. Although an optimal generator would be a lossless type that doesn't produce magnetism in its operation, instead maintaining lossless transmission in the form of dielectric current, this is how Tesla's hairpin circuit works by cleaning out the magnetism in an already inductive current, although I don't know if it's possible to generate pure dielectric current in the source. Although it's possible a generator that has had its back-emf suppressed via capacitive resonance is producing dielectricity instead of regular electricity, more research needed.

IMHO it could a good video three wind turbine moving generators of exact same type in the exact same place at the exact same time and compare the three later in the lab.
