Dear sir. This is brilliant! However, I may have some suggestions, to increase the output, quite easily. The diodes in the rectifier will eat up at some 1,5 volts and produce heat of that, if it is a standard silicone bridge with 0,7 to 0,9 fall over each diode. 1,5 V is quite a deal if the generator produces some 3 V. It is 50%, that get lost. If the bridge is built by 4 shottky diodes with 0,4 V fall over each diode, and just eats up 0,8 V over the bridge, the losses will be decreased by a half, and the rectifier would be close to 75% effective. From the generators 3 V, there will be left 2,2 V, instead of 1,5 V. Next thing is to increase the number of turns in the serpentine coil. By doubling the turns the voltage will be doubled into 6 V, and there will be 5,2 V after the rectifier, and the rectifier will just eat up some 13,3 % of the power. There will be a limit, depending of the space allowed for the windings. The general rule is to keep the windings as tight as possible, and as close as possible to the magnet field. A millimeter closer is crucial, and can make the 6 V output into 12 V, and Now we talk. 12-0,8=11,2 , and the rectifier will be 93% effective. This correction, will increase the mechanical resistance in an equal way, similar to the voltage gain. I.e. It would not spin as easy as before. This was suggestion 2, and 3. You never get something out of nothing. But there is a fourth thing to consider: You can always use a transformer, to multiple the voltage, before rectifying. There is no rule that says that you can't get 230V out from a 6V source. But a transformers efficiency depends on the frequency, and what kind of iron that suits the best.. For frequencies say 30-400 Hz, standard E-I steel-blades works relatively good as core material, but over that, it becomes more and more complicated, though iron powder and ferrites will be better to suit the frequency. A solution like this with windings at the peripheral, may well produce kilohertz, as well as 20 Hz, and no iron suits this span. You would also have troubles to handle a span from 3V to 3000V, but all is dependent of the Min-Max spread. This is very complicated, and transformers are not 100 % effective. My suggestion to make a generator is that it don't exceeds 35 V in a storm condition, though you can use cheap electronics to charge batteries, that will hold the energy, that can produce other voltages for needs. But consider, that there are losses involved in every stage. Use step up, or step down converters i.e buck-boost controllers, use MOSFET transistors, and the best quality capacitors and inductors, to minimize every loss. Take care to search for the less needed stages for it's need, and Keep It as Simple as possible. So dear Mr R.M. Smith: I love your turbine, and the way you preaches simplicity. I totally agree with you. I just wanted to add some thoughts. I am a Swedish, over aged engineer, that can't resist work, though I am alone, so I stay halftime. I love to watch your movies, and loves your wonderful laughs. My best regards.

[@justtinkering6713]

Transformers will increase voltage or current but not watts. Also a low impedance winding on a transformer will greatly increase the load. The rpm will suffer as will the power

[@screen-protector]

I agree that you can use and Shottky diodes, yes, that's right. But, this was mentioned even in this video here and before. This is a proof of concept, Robert was telling to put the money where he's mouth was. ;) Making it dead simple to create and play with it at later stage. It's not about the perfection ;). Yes, you can use transformer, but, if you're going that far, worth mentioning that a linear transformer has a higher loss than a high-frequency one ;) - less windings, but you need to understand the MOSFETS and the protection circuit ;). This efficiency would be better than a regular transformer. As you've mentioned about the frequency, you know what I mean about the switching power supply and its uses. Because you don't want switching one for instance in the audio system of a higher quality ;), or medical stuff. As per your other suggestions, why not do something and show it to everyone? :) You could put your money where your mouth was. :) That would be nice to see as an improvement and you don't have to 3d print even :). If you can achieve a higher efficiency, you can use materials from the recycling :) and will have a better efficiency :). But hey, it's me and my opinion, you can do what you like ;).

[@philip5940]

There's a way to wire up MOSFETs or suchlike to yield no voltage drop rectification. Cost and simplicity though I don't know.

[@justtinkering6713]

@@philip5940 its called a synchronous rectifier.

If all your interested in is a voltage boost then just make a Schottky Bridge Doubler Circuit. It doubles the voltage It only has 4 diodes and 2 capacitors. I've used them many times

Yes so very promising right ? ​@RobertMurraySmith I went for solar so I could have a few of the bits and pieces to allow to plug stuff like that in...

[@Anti_Woke]

@@bdanuw Yes, but I'm sure Rob would point out that by the same token, it probably won't survive a gale! For prototype 'works' is good, but for a real thing you'd want to design for the strength of wind you expect.

@@Anti_Woke Or a way to restrict airflow for higher winds

[@Anti_Woke]

@@ctakitimu I'm designing for use on a small sailing boat, wind speeds up to 40mph - and being able to pack it away when the winds get higher than that! Obviously that places significant structural demands on the system, not just the turbine, whether it's collecting or deflecting the wind. (Working on sailcloth Darwin funnel, hoisting more or less as the wind conditions dictate, or collapsing the whole thing to pack it away)

[@burrowknoxwoodworking]

You nailed that idea keeping things simple. I used to over complicate designs to the point where it stayed in my idea book. I've learned to just keep it simple... actually build the dang thing, and complete the project. I live with the design for a bit ....use it, look at it and think of ways to improve it. Sometimes, I'll iterate. Other times, I'm completely fine with it

[@ThinkingandTinkering]

surprisingly enough that takes a fair bit of learning lol

[@evo-labs]

I think a better question to ask its "can I make it MORE simple/LESS complex". In engineering, complexity is relative, something than may appear to be 'complex' is often as simple as it can be, just not as simple as the observer expects it to be. Of course when you add cost into the equation, the simple vs. complex argument becomes polluted because less complex is associated with lower cost, that doesn't necessarily make the product better.

[@TheBaconWizard]

A rim-speed generator built-in to the turbine of a wind-tower of the kind you've been prototyping recently seems like a superb way to go for many applications.

​@@ThinkingandTinkering hi. I have one idea and I'd like to know your opinion. What do you think about applying venturi pump to hydro power dam? I mean, if we could connect venturi inlet to discharge of dam we could create 7/24 environment friendly wind and by applying one of the super efficient wind turbine to air suction for creating energy. But I have some doubts about if it will decrease efficiency of hydropower. What do you think?

You enjoyment in testing your experiments is absolutely infectious! Keep up the great content Robert!

[@coffeeshangarworkshop8051]

In a windwall configuration, if you stacked them, design units to rotate in opposite directions. Each unit could have magnets on the top, and coil on the bottom, and alternate the rotation directions as you stack them.. The more you stack the more power you get, and each unit gets double the effective RPM because it's rotating in an opposite direction of the one above and or below it.

[@heinerphilipp]

Smoke another one. The next idea will be much better.

[@donaldgulledge729]

A stacked counter rotation version I would really like to see. I believe just inverting one of two identical units would result in the one on top rotating opposite of the one on the bottom so your build cost would still involve only one design. I believe it would however require including a axel bearing on both ends rather than only on the generator end as shown. This would be a great project to upscale test.

[@Glenharris1971]

[@custos3249]

I'm always 50/50 on the idea of simplicity in engineering. Its benefits are obvious, but that same mentality would rule the car, plane, even computers as too complex to be worth it today. One can try to point to the goals of Mercedes and the Wrights being exceedingly simple compared to where we've carried those technologies today, but that's just the thing. It's nearly impossible to get simple devices off the ground these days. We're so jaded with so many "mature" technologies, fledgling tech and alternative paths have a hell of a time competing, especially since engineers are very fond of the stagnant legacy "if it ain't broke, don't fix it." And that's not even touching on problems created by market behemoths having every tool possible to shoot down the little guy with governmental help in some cases. There are a lot of alternatives we should be looking at to replace windmills, yet were still using the same basic design used in a pedestal fan because the old farting dog we named Industry knows it has the best approach if no superior method is sought and found. And with no real competition, why innovative? Where was I going with this..... End of the day, something shouldn't be simple or complex, it should only have the level of complexity it needs to function, plus the safety factor. Edit: And then there the "best solution is not to have the problem in the first place" people. Anyone who seriously invests in that brain dead platitude should be handed a gun with a single bullet and reminded that, according to their own philosophy, they now have the means to solve every single problem they have, have had, and will ever have, so how about a demonstration? The rest of us have things to do.

[@ThinkingandTinkering]

no mate simplicity Is always present - it is made as simple as it needs to be - a computer is a stunningly simple thing - it is just switches arranged small and that's all it is - when it comes to manufacture the approach is always the best part is no part and the best process is no process - a ton of effort goes into reducing component count - I think you might have some confusion between simplicity and simple

[@HendrikStander-v1l]

If the main subject is "keeping it simple an cheap" there will be no progress. Because simple and cheap is not progress. Savonius can only become more efficient by making it more complex. Efficiency must increase with the same swept area.

Hi Custos. If nothing in a design change , the result stays the same . This channel is about marketing of 3D Printing. To do the print you must create a 3D model of something using CAD. The CAD file is then converted to a STL. File this file format supports 3D Printers . So if I want to sell a 3D Printer to a novis I must have exciting things he can print. So If I have STL files that I can supply all the novis must do is learn to operate the Printer and load the STL files. So if you are a turner and machinist and you know CAD you can do CNC programming also. So for the novis everything must be simple and cheap

I think the easiest way to get a project like this going for parole is with some BMX bike rims or even big racer rims .

Looks great Robert,works great looks, it looks allot like the kite I told you about years ago that I bought as a kid, they were army surplus (I was told by the vendor in the golf area of the United States). They were made of Styrofoam, and had orange and white coloring on the rotor portion so that the colors alternated as it spun. With the wind on the beach they would stay flying without attention, he had them staked out all over the beach, which is how I purchased one. The string for the kite was attached to the pivot point in the center on either end of the spinning drum and joined together as one Kite string. Thanks for this build! Always wondered how it would do. Excellent. The kite had an airfoil cross section of each of the two rotors blades. I really like that you have revisited this with flare. Your rotational ventilator cap generator was great as well. And the later variation with it's isolated salvage transformer pick up coils was a stupendous build also. Great stuff. Would love to see how one made of industrial insulation 10 feet tall and five in diameter would do it, but hey all you need to do a scale of the math right? But still I wonder what a big beast might do. Honestly I could say I would really love to finish my years living in an active version of a dutch windmill with this thing for a rotor built into it. Or maybe just a dutch windmill with him create parts, there's a lot of room inside of one of those, perfect for me. I always wondered how a design like that would work at the peak of the roof on my house . ...

What you said Robert is a fact. Simplicity of design is what makes things work beautifully. Making it easy for others to copy and use the idea and pass it on and on.

The silver plate really increases the efficiency of the coils. . Job well done fella too. vf

[@JSabh]

Agreed on the simplicity needed to actually manufacture something. Although, clearly we reach a point when the simplicity goes out the window, as it does for engines and power steering systems and the like because the demand for robustness outweighs the easy of keeping things simple. Looks like the automotive industry figured that out a long time ago but, I do think they go overboard at times lol. To start with, your 100% correct on simplicity, to go forward however requires more complexity. If they can build millions of cars and have been for over 100 years, then I reckon anything can be made cheap enough to manufacture given time and infrastructure.

I contend that if you're going to 3D print the turbine you may as well have 3D printed the Ugrinsky turbine, which is significantly more efficient. You don't benefit from the Savonius being simpler if you aren't manually making the turbine and are just printing from existing models.

There are lots of 18th century inventions that worked, they're simply less efficient than other methods of doing the same thing.

[@phatsossage]

Hi, may I suggest that if you were to deflect the wind away from the returning blades on the opposite side of the working direction of the wind by adding a directional tail to it you will enhance the efficiency of your turbine a great deal! Vertical axis wind turbines all suffer from this to overcome the force of the wind on the blades on the opposite side of the working direction and all future VAWTs will benefit from this addition. I am currently working on the concept with astonishing results.

[@carlswanson8041]

An interesting thought on how to effectively double the output with the same wind speed would be to stack as you thought but to put the coil on the top of the lower turbine and having the upper turbine reversed to spin the opposite direction with the magnets on the bottom of it. There would be some loss due to friction drag since one would have to use a spring loaded contact (Think street trolley or electric train) since a straight line connection would not work but still it would drastically increase the power generation and could be multiplied with each additional turbine stacked.

[@shsummers]

My thoughts exactly - counter opposing turbines doubles the output at a given wind speed.

[@ThinkingandTinkering]

interesting - thank you for sharing

[@markgeurts258]

That's interesting! This way you double the speed and even in very low windspeeds, you maybe have a better power convertion?

[@ryandoyle4344]

Amazing Work!! Great proof of concept & love the KISS method. Would the complexity of additional power generation over complicate the design? Perhaps, modify the top plate for magnets also w/2nd coil plate; the required longer shaft & bearing may also stabilize the unsupported topside of the fan.

[@Ada..D]

Excellent 👍 very interesting stuff.

[@zylascope]

Awesome. I'll try that one! Thanks for sharing :)

[@dualxsurvival155]

Imagine how many leaf driven turbines you could stack in one spot with this design

[@arthurkinnell9891]

Brilliant idea - you're a little exocet Robert. Keep up the good work!

[@Secret_Squirrel_Scottishgamer]

Robert looks like a young compo from last of the summer wine. lol

[@SCARLETBIRDS]

you could put magnets on the top and bottom slightly offset to reduce drag while doubling the amount of coils and maybe replace the plastic winding bits with iron cores as i'm pretty sure that would make the field stronger as it passes, to keep the upper coil stationary just add a C frame holding the top and bottom coil plates as a set

[@BarefootBeekeeper]

I made a 3-bladed parabolic Savonius rotor in 1975.

[@sidster64]

Great mind think alike and your mind is great great video

[@nickn.332]

These are super cool and I'd love to make something simlilar myself! One reccommendation to anyone else making something similar; Put iron cores in the wire bobbins, a nail or a bolt is a cheap and simple solution and the practical magnetic flux achieved by a ferromagnetic core can be orders of magnitude greater than an air core at the frequencies you're switching the magnetic field at - this will put greater resistance on turning but with a good breeze this should be more than powerful enough

[@hunnybunnysheavymetalmusic6542]

I would say that logically, indeed, do start out simple, make it, then, if you are then inspired enough, you will have one while you make anything more complicated later on when you are more inspired from a first success.

[@Milkybar3320011]

Keeping it simple works in line with the power generation, these small energy outputs are easer to learn/work with. The bigger the generation, then essential life safe systems need to be in place.

[@ThinkingandTinkering]

absolutely

[@corvus2746]

Dude, you are a GENIUS!!!

[@Dave_D.]

Well, we always knew RMS was full of hot air! LOL Love your projects.

[@elalcalde3362]

These would be perfect to place on the corners of the compressor for an air conditioning unit. I live in Florida and would love to scavenge a little electricity from the AC running most of the day. Thank you for the great videos!

[@ThinkingandTinkering]

nice!

[@BillHartCooks.]

So, what about doing a Print that would sit at the bottom of one of your wind catchers, the tower with the flaps.... That is based on the same idea. Something that is about 10cm thick that has vanes and the rim mounted magnets with the serpentine coil. If you are going for rim speed something larger in diameter would be awesome, but I don't know how big your printer would print. Something about 50cm in diameter would be really cool. Speed at the rim will go up exponentially at the rim with an increase in diameter. If I ever come across the pond I would love to come play in your workshop for a day or so.....

[@kazmo27]

I absolutely love you, awesome as always 💜💜💜💜💜

I wondered when you'd get round to This. Yin Yang ☯️ Very old .A good study .

[@mrdewilliams]

As you were blowing on it, I thought to myself, "He is going to make himself dizzy." Just following that thought, I heard you start laughing, and thought, "Yep. He's dizzy already." 😂 Loving the videos. Keep having fun.

[@Ryder-qx1df]

Some zerks would be a great feature of a way to change the bearings out

[@jamest.5001]

I have seen these turbine made from 40-55 gal. Drums, it just seems to too small in diameter to be effective, the efficiency looks to be low, the disc type like you made , with the feathers in it, seems a larger diameter disc, about 12'with feathers made from 1/2" conduit, and wood coated in a layer of fiberglass and epoxy resin, mounted on an axel made from. Seamless tubing, to allow a means of control, to close the feathers to regulate Voltage or to prevent over speed in a storm, If it could be made double action, by having feathers that can be spring loaded to act against gravity on the bottom side of the disc. The top lifting up, pushed another feather down, a spring can then close it when the wind isn't forcing it open, I suppose if you really wanted to harness all the energy possible, the motion of the feathers flapping open and closed could be harnessed, using a slip ring. The feather could have a 25mm x 3mm magnet mounted to it, with a oil mounted at it's mid point of it's range of motion, the magnet passing the coil possibly using a pair of magnets, and about 22 gauge wire, and a rectifier, the wattage would not be that great, but could be used to charge a small capacitor bank, about 48-60v bank of super caps in the , 8- 10 farad range using a dc to DC buck / boost converter, triggered to power on when the voltage peaks, discharge the capacitor to about 18-20v to 48-60v however the capacitor voltage works out, As for harnessing the feather turbine power, use a 24-36" double disc, using about 50mm x 10-12mm N50+/-, magnets forming a 24"-36" maybe 48" axial flux generator, using plywood with routed grooves for the magnets to fit inside, after the plywood is heated to about 220°f for about 2hours to remove nearly all moisture, as it cools to about 120° do a vacuum infusion of thinned epoxy resin, allow the moisture to be replaced by the resin , stabilizing the wood, it should last 50 years plus. If treated well, spin as if on a lathe making it flat with the axel, then use a router to cut the grooves, use a quality epoxy to glue the magnets with use the ultra thin fiberglass, to seal in the magnets to allow the magnets to be as close as 1mm to 1.5mm to the coil, possibly closer, with the coil being placed inside a similar plywood ring, using a non coiled winding, possibly using 18 gauge enabled wire, sealed in epoxy, with the outer edge o the magnet wheel wrapped in carbon fiber tow, tightly wet wrapping to prevent nai think a 24" axial flux generator would be best, being it going on the top of a tower, made from two sets of 20' tall angle iron 4" mounter 24" spacibg 24" frim each other, connected wuth a 4" channel iron , wit a 2" tube brance cimibgbin ag a slight angle, about 12"from center all uprights mounted to 24" long screw in anchors screwed into the bottom of a 36" deep post hole, 10-12" diameter, each, so 6 anchors, with 4 holes in the corners with 1/2" rebar driven into the bottom of tge holes plus a ground rod, to ground the tower, connect the rebar about 1" above earth, using 1" bolts connected to the anchor, by welding to rebar, and pouring concrete into the holes, then about 4" above the ground, making the pad about 4'-6' x 4'-6' with a 2" bar crossing at the top at 20' allowing the tower to tip, using four pieces of 2" angle spaced 12" x 12" cross braced by . 5" bar stock, at 24" centers at a 45° angle, tilting at 20' high, with an additional 30' with 10' beliw tbe tilt putting the turbine about 40' above ground level. Using 1/2" bolts on the bottom of the tilt , that is pulled down with the winch, the 4x 2" angle brought to two two angked into tge bottom of a 2" thick wall tub the othe opposite pair of angle , Angled into the , 2" tubing about 4' up higher, this puttibg tfe top of tge 2" tubing at about 40' from the ground. Then mount the feather wheel turbine, and generator, The feather being 12-18" wide at the outer end, using a 1/2" conduit as the axis and spine of the feather with a 1.5" strip of 1/4" plywood, forming a frame tge corners of the plywood ground to half thickness then using epoxy and brads to secure, a 12" wheel using 5'6" feathers, that 4' of them are are about 16" wide with the feather ply section running parallel with the conduit, for 4' then run at a angle to connect to the conduit at tge end, using a L bracket on each end with a hole and a piece of tubing wrlded to ti allow a bearing to fit in , to use a bolt to fit the 1/2" tubing, with a small bolt through the tubing and bolt, making a shaft riding on bearings , the 16" by 4.5' of feather should catch a good bit of wind, especially with another pair working on the bottom side, stick a 32" x 4'6" board out a window at 20 mph, if you could hold it , you would probably be ripped out the car, and at highway speed, it could possibly pull the car off the road , maybe even wrecking it, it's over 12 sq ft, mount this on a 12' 1" wheel of plywood, most likely laminate 1/4" sheets alternately to form a 12' disc maybe 1.5" thick to allow the overlap seams to be stronger, possibly cut into 2' x 8'strips to make a or cut a 2' x4' corner out of the sheet, aviut 3layers should be eniugh for overlap strength so 2x 1/4" and a 1/2" ply center, use epoxy resin, thinned, and dry the wood, find a concrete slab, and set up a small pool con it if possible, a 36" deep 14' pool should squeeze all the air out of the glue! Let set for the weekend, make a pair of 12" hubs to fit in the center, cut the 12' circle, then slice into 4 slices, use the hubs to hold it together, with flat 1/8" bar on the ends, assemble it all using 2" magnets on a 24" wheel, maybe use two 2" magnets making a 2" x 4" magnet , using the serpentine winding , using much less wire it could possibly used! By using individual coils, about 9 poles , 3phase, enough turns it shiuld produce about 1volt 1 rpm and 10 amps, abd hopefully do 45-60 rpm in normal wind, do 600 watts easy, and peak power for a 24v system at about 90 rpm, and should hopefully be capable of 2kw+ sorry to ramble Soo much, I get like this with the insomnia, especially used with a minute classic charge controller, it should be 20 amps per phase and 100 volts, with the emert mechanism closing the feathers at 120 volts, atleast 50% closed to reduce power in high wind, hi voltage, 20a 120v us nothing to complain about, 2400w at 28 v its fetting near all 96 amps the charge controller is capable of, on breezy days it should ve possible, even if it requires two feather turbines on the shaft, sorry again to ramble!!

Honeywell Windtronics did this over a decade ago (power generation on the outside perimeter vs center) Ran in wind ranges of 2mph-38mph.

[@ThinkingandTinkering]

didn't they try a modified HAWT?

[@rowgler1]

Yes, I remember that, it had no central axle, the bearings were around the rim, only ever saw pictures, did it ever go into production?

[@derrick1759]

@@ThinkingandTinkering No it was more like your design in 1865 but vertically mounted. Looked like a bicycle tire inner spoke frame inside of the stator ring.
