A question for my German-speaking viewers and those that want to learn German: Would you like to see German versions of my videos as well? I would upload the German version a day or so after the English version and those video would than also pop up in your subscription feed. It would probably annoy some of the international viewers. What do you think?

[@RainerTrunk]

Videos in Deutsch wären gut. Ich spreche zwar gut English aber mit Deutsch versteht man manches besser.

[@abdulazeez.98]

I'm an international viewer. I don't see anything that would annoy me in any way, even if it pops up in my notifications feed.

[@edgeeffect]

Do you have the intro in verse auf Deutsch too?!

[@Hagledesperado]

I don't know if mixing languages on a single channel is a good idea, maybe upload German videos to a separate channel? I'm not a KZbin algorithm expert, but I think I've heard that these algorithms don't like channels where some videos get many views and other videos get few views.

[@kbhasi]

@@Hagledesperado Yeah, I agree, he should do a separate channel, where the channel name is the same, but directly translated, or whatever he feels like what he uses.

[@thebeststooge]

The old western USA style windmill had a lot of blades because it was made for torque not speed without the complexity of gearing that could break down (remember a lot of these places would be like a tank in the desert and would fail a lot or demand a constant daily, if not hourly, maintenance of those gears if they had them so they let the wind/blade design be the torgue producer) so it could lift the water out of the well. GREAT for that but not for generating electricity.

[@roadeycarl]

Definitely give it another go! I feel like the word " failure " is thrown about two easy... true failure is if you don't lean anything from an experience. I don't succeed and a lot of projects I make, and sometimes even the most simple things trip me up occasionally, but I learn from it and move on. Not succeeding is a very important part of succeeding!!

[@dohnjoe706]

Yes! Please continue this journey. I believe a great many of us would appreciate an established maker's approach to wind turbine builds.

[@richardperritt]

I believe re-visiting alternative energy production systems is a fabulous idea and fully support any endeavour. Keep up the good, nay GREAT, work!

[@Godshole]

I used a 12v Rutland 910 for several years to charge a 200AH battery pack for lighting and a car radio/cassette ( it was a long time ago ) The generator was called a furlmatic and had the tail offset from the center and the rotor bearing slightly offset from the center axis, with the paddle on a hinge, so that when a strong gust came it would turn sideways to the wind, slow itself down and protect itself from overspin. In the highlands of Scotland it worked a treat and I used to sit and watch it through the window. It would generate 2 amps in a fair breeze and peak out about 8 amps if I remember right. 5 Blades and a span of a meter. Heavy duty slip rings and it came with a spare set of main bearings. For anyone wanting a 'shed' power system who has a breezy, clean site wind wise it was a great machine. We used it in our off grid caravan and apart from the three weeks with NO FUCKING WIND AT ALL when we first put it up, much to the delight of the locals, it worked flawlessly for years.

[@ExtantFrodo2]

*" three weeks with NO FUCKING WIND AT ALL when we first put it up"* That's Murphy's Law hard at work. :-(

[@user-vj1hy8si7p]

I enjoyed that. By all means, help your parents pay their electric bills. Another idea would be to attach LED lights to the wind turbine, which would then charge a battery by day, and power a psychedelic light show by night.

[@mindthependulum6245]

It is good to hear you sound so happy lately! I used to work as an auto body technician when I lived in rural Texas. I used a rear brake drum from a mid sized industrial truck, an old Ford I think. The drum was very large and heavy. I used a bearing and spindle from a flatbed trailer as the middle. I used three alternators from dead Chevy cameros that we're rotting on the back lot. I used gears from old gocarts and motorcycles welded to a bracket near the opening of the rear of the drum which spun with it. All three alternators had gear sprockets welded to the ends of their shafts and were mounted in a triangular fashion near the rear of it all. I calculated the drive ratio on the drive sprocket on the drum and the sprockets on the alternator shafts to have maximum speed to the alternators. We also used a donated propeller from a light aircraft. It had three blades, but it wasn't the best design for this application. All the diode sets we're removed from the alternators to give true ac power. A customer of mine who sets up ham radio antenna masts, traded some body work in exchange for putting this odd thing on top a 30 foot mast. This was over 20 years ago and we didn't care much about attaching batteries to it, but I wish we had. The real pain was regular lubrication. The chain would get noisy and it did brake several times, at least until we got a new chain instead of using a recycled one. It was attached to a make shift breaker box, so if the wind got too high, a breaker would throw to prevent a fire. It was all connected to some outside flood lights and nothing more. It was fun and wierd, but many of the best things in life are.

[@kieferonline]

I would really enjoy another go at a wind turbine project. Please go for it if you can! As for the language question, I'm American and also do enjoy hearing the occasional German vocabulary in your videos. I don't know of any other bilingual channels on KZbin that have alternate languages. It might confuse new viewers, but I personally wouldn't mind watching those. German used to be the premier language of science 100 years ago! Somehow German vocabulary seems to work well with engineering even today.

[@BernhardHofmann]

It was these old videos that got me hooked on your channel and I'm still enjoying what you do.

[@gregorygonzales3909]

Given the status of energy security in the world today, I think revisiting this project would be very timely and make a wonderful contribution!

[@BlazerProject]

Wind Turbine builds would be nice to see and also interesting to see how it is all hooked up.

[@AdrianCubas1980]

The first time I saw this video, some years ago, I did not understand how the Darrieus rotor could work, I found it absurd. Some time later I started to develop my own prototypes with the help of a 3D printer and modeling software. I managed not only to understand the operating principle of this type of generators but also to help others so that they also understand it and can easily replicate it. There are videos on my channel that prove it. Thanks!!! Your videos have been an inspiration to me.

[@rowlandcrew]

Hi G, I like the insertion of german technical terms as you did here. My idea is that different languages side by side lead to better understanding for all because the roots of words have slightlt different meaning.

[@thedave7760]

Awesome comment I agree totally.

[@naderfawzy5958]

3:22 I wanna thank you for this words. ♥️♥️♥️♥️❤️❤️❤️❤️😍😍😍

[@boarderlinesk8media433]

Yes please do another turbine build! Like the water wheel!

[@psygn0sis]

I would LOVE to see you tinker with wind turbines again, seriously!

[@itzdono]

You should check out the double helix VAWT. Can also be mounted horizontally. Loves turbulent wind. Maxes out at a little over 300 rpm so vibrations won't tear it apart in high winds. They're testing them here in NY on roofs in the Bronx & I believe they were invented in Chicago. They don't hurt birds, either. Very scalable to whatever motor you're using. Could also be wrapped around a pole or tree. Most people think they're sculptures. It's an elegant design.

[@Hagledesperado]

DIY power videos are always interesting. Go for it! Nice poetry BTW.

[@cooltimo]

I would love to see an updated DIY wind turbine that could generate enough energy to store. Thank you for hosting an awesome channel!

[@henrikbakheyde]

Investigating and building VAWTs would be interesting to watch. About the language - I personally dont't care. It's the content which is important to me!

[@SheddyIan]

I would like to see some more videos about small scale wind turbines. I think there is a problem with small turbines particularly in urban areas, that the wind is too disrupted by other buildings and that wind does not scale down well. A larger turbine, positioned where it has good open airflow is much more suitable than a small one near ground level. In the UK in the last 10 years or so we've seen solar and wind systems available at relatively cheap cost, but whilst there are now many house roofs with solar panels, it is rare to see small turbines. Despite this, I would still be interested in videos of design and build of turbines , and what problems you might encounter. Thanks for interesting videos, and for teaching me a little German language as well.

[@axnbjsbdudbydvydubu9355]

this is a very important project that you must follow and work on in much more details spanning many videos instead of these SCi-Fi like projects .. this one can be useful rather than just youtube entertainment and it really helps against pollution of fossil fuel

[@michaeldenton8610]

I worked with this myself and I found using aluminum and fiberglass was optimum. I used a three blade design. I ended up with a 160 amp car alternator that had been modified to not limit its output. The best way I found was to let three of these models power a battery bank. My battery bank consisted of a bunch of used deep cycle batteries and somewhat restored car batteries. This was set up and I took my home breaker box apart and used the battery bank to power the lights in the home. Ended up with a couple screw vane types and I placed them on the roof they powered some golf cart batteries. These were connected to the HVAC to power the blower motor. Although I did have to install a capacitor to get the fan going that reduced my power bill by $120 USD

[@mihai1339]

I would love to see another wind turbine related video.

[@Teknopottu]

Responding to an old post; Me too but stuff like that seems rare and when treasure hunting, my favourites, vices and lathes it is once or twice a month. Gladly Robert Murray-Smith offers more diverse content and almost daily. Repurposing stuff has always been most interesting to me. I'm their patreon too but been thinking about TPAI; do I really want to pay mostly for his older content?

[@barrycrowder]

I'd love to see more of your efforts with wind turbines! Something to look into is applying a resin/fiber coating to the XPS for the blades. Basically, apply a layer of cloth (fiberglass) and coat with resin. Adds minimal weight but a high degree of extra stiffness. Would probably be more aerodynamic than the bare XPS, as well, because the surface would be smoother.

[@vaughanwarburton9623]

More like this please ,easy to make with easy to get hold of parts

[@nealberger3760]

Yes, go ahead! Make the video! But make a simple, cheap cost wind plant that we all can easily follow through with our own constructions. Get rid of the unnecessary tail vane and make the propellers a downwind turbine design. Shape the turbine chassis like a teardrop. Put your wonderful German inventiveness to work! Let's see the result.

[@ianbutler1983]

One other point. I have spent a lot of time out in the western USA, on the prairies. It is flat out there, there are no trees to speak of, and most important, 20, 30, or 40 mile per hour winds that blow for days at a time are common. The windmills drive a vertical shaft with a simple lift pump that deposits an ounce or so of water into a giant (hundreds or thousands of gallons) tank with each rotation. If the wind stops for a few hours or days, it does not matter, the huge tank of water will provide for the cattle. They are cool though, I always felt like I was in a Clint Eastwood movie.

[@alexa.9436]

Mach unbedingt weitere Videos, ich finde das Thema richtig interessant weil ich selbst immer schon gerne an windrädern tüftle.

[@andrewchurchley5705]

Even your failures are highly instructive! I like hearing the translation of key words as I have a smattering of technical German. But for me, and much of the world who have English as a first or second language, use of English is greatly appreciated.

[@apollorobb]

I like the wind generation idea. And I also like the German/ English idea

[@breslins]

Yes do it! If I could hook up an h rotor to my roof I would be king of the trailer park!

[@violencejack750]

DO IT , WE ALL DEMAND A POST APOCALYPTIC POWER STATION!

[@denislostinlondon199]

A small and simple wind powered generator would be great for city gardens.

[@rebelba42]

In my opinion it isn't necessary to upload your videos for both languages. Learning english while we are watching your great channel, is one of the beauty we have with KZbin these days. Although I really like that you're always name the german word in addition to the english term in your electrical or general explanations. Thanks for doing this channel and keep up the great work! Viele Grüße aus NRW :)

[@gordonconway3538]

Yes I would love to see a new turbine build as I am currently in the design stage for my own build with possibly multiple 24v alternators for my 100% off grid Motor coach that has a total of 7,000 watts of inverters installed

[@basstard13]

It's years I fantasize about building a wind turbine. Now that I have my place I'm more interested and when I saw the notification of you doing a video about it I was: "if he has one of those super detailed videos, I'm gonna build the turbine for sure". So that's a huge YES, do it please!

[@LostDeadSoul]

Hi. I have also thought much about this idea and have also spoken to a few people who gave me something to think about. The thing that cools your house is the wind with it's temperature as a coefficient. There is not much more than scaling you can do to compensate for the temperature as the chill factor. But what you can do is make a turbine that has the average heat loss of your house. That would require a bigger generator than you have used in your project. Also raise your turbine over the height of your house so you get more stable wind. The most effective way to convert wind to heat is NOT to convert the power to DC. If you want to charge a battery i can understand that you'd like DC. But for heat?... Think of it this way. If you have a three-phase motor which is directly connected to a three-phase heating element. When the wind cools your house, your turbine spins up proportionally to the wind speed. If you have a hurricane your small turbine might produce more than designed, but the heat loss will be proportional so you won't over-heat, theoretically. Now, you may see that for you to make use of a turbine as a heat provider you need a pretty big one, but 2-3 meters in diameter would do you some good. Just make them glass or carbon fiber with your foam as a form :)

[@jamesmauer7398]

It is good to see those old wind turbines again! I was interested back when you first put footage of them up on youtube. A project using wind at your parent's would be cool.

[@Maker_of_Things]

Yes please. If you have the opportunity please do follow up with some more small scale power generation. Maybe looking at simple PV and Hydro as well as wind. It would be a good learning process for many who want to experiment and need to know how an where to start. Thank you.

[@chris993361]

I've been interested in making my own turbine and I would love it if you would bring back that project. Like all your videos that was great to see.

[@wmman8256]

To keep those blades hard and ridged cover them with a woven fiberglass cloth coated with epoxy resin. Then sand them as smooth as possible with wet sandpaper for that glass like smooth finish. Then they will withstand almost anything nature can throw at them. And make sure they are balanced properly. They will turn more easily then, and reduce binding or wear on the bearings.

[@reggiep75]

I'd like to see more wind turbine projects if you are wanting to do them and another 3 fin H-rotor would be a good start.

[@oby-1607]

Please, more wind turbine videos please.

[@kerrfamilylaw7487]

I would like to see more wind turbine builds also with sun panels for a hybrid system with all the components on a shoe-string for off-grid power...(please)...

[@entemomohTV]

I would very much apprechiate it, if you tinkered around with windmills a bit more. Even if they are not going to produce vast amounts of electricity. Maybe you could also take a look at different genereator types aswell, for example the type where you use multiple transformer windings in conjunction arranged in a circle...

[@JamesBiggar]

See my channel for examples of efficient, true off grid DIY axial flux wind turbines. Built from scratch, generator and all. Plans are available.

[@danielthrana]

I like that you are honest and say that it wasnt worth it. However I would be interested in a build of a wind turbine that is worth it and will save some money.

[@thejustmechannel3298]

I'm from the US an my GF went to w.m.u. an one class was German. I love that you do post apocalyptic styled videos. An even more the wind power builds. Mostly love love love the English to German wordings an all. So yes please yes to all!! :D Many blessings to you an your family. Keep the builds going brother.

[@res1492]

Engineering, Electronics, Aerodynamics and German language Classes all in one...love it!!

[@ronyerke9250]

Perhaps you could try using a roof as a space for your wind powered generator experiments. Would your landlord be okay with that? Some YT productions utilise subtitles to expand their international audience. Maybe you would consider giving that a try.

[@zackmerritt2408]

I’d definitely be interested in seeing you take another shot at this project. i definitely see some real potential and think you could make some great improvements with the knowledge and resources you’ve gained since your first attemp. i’d definitely like to see more!

[@kampkrieger]

Finally a german guy who can speak english

[@mindthependulum6245]

To bring a point on something you may wish to know, I joined this channel to see very interesting recycling ideas. I grew up in a time when old hippies were the best recyclers. They could take 5 broken things, and make three all new things with new purposes. As a boy, I was inspired by that. Home power generation is a very interesting topic to me, and likely to many others here. You could make a series of videos on the different aspects of what is needed for this. Such as, make a test bench that tests the ability of different types of electric motors to generate decent power, and at what rpm's they would need to spin at and so on. Another, would show how to convert a used automotive alternator to generate power. Another would focus on proper mounts, and heights to mount it all at, including bearing basics that work well for this. Another video could focus on blade design, how to make or which kind to purchase. Another video would show how to connect this to a home power grid with some safety measures and the use of a battery bank. Those are just a few ideas I have for this. It seems like a rich topic with a lot of potential for you and the viewers. I for one, would be excited to see you do this!

[@panicfarm9874]

I’d love to see more wind turbine videos

[@yewsengcheong1637]

Would still love to see a wind turbine video please!!!

[@theantasist]

I'd really like to see wind turbine videos from you

[@frac]

I definitely found that interesting. And I see the limited budget as a plus. I love seeing what can be done with salvaged parts.

[@derpinbird1180]

With your skills you could probably make something but it needs to be scaled up and put higher up in the air. Get one of those weather station things, that way you can predict how much wind you will have and therefor you can use the results of a diy design (or maybe some other design you can copy) to determine how big it should be and what it should make.

[@bobkirby2603]

Would be interesting to see what you can use to get power supply to ie Battery to charge up. It was interesting watching what you did back in 2014. My idea was to put a car generator 12volt try with a blade on it but all I thought of was 50 cm blade top to bottom? All in my head but one day in new year I suppose I will have a go! Thank you for remenising with us. Love watching what you do, electronic stuff you loose me I'm afraid. All the best Bob.

[@ducomaritiem7160]

I like the idea of building my own windmill. So, a big like for more windmill generators.

[@eBola1012]

I say go for it! I’m really looking forward to watching a proper diy windmill being made! =)

[@davewoods177]

I watch your channel as much as I can. I think you should stay with the apocalyptic idea. Perhaps you should make a bicycle based car battery charger. I recommend the DC motor from the treadmill machine.

[@shedactivist]

Thank you for this video (and your great channel). I am just about to experiment with wind generation with my 12 year old son and this was most helpful. I just want to keep a battery topped up to power an Arduino based light display to show wind speed and direction on the vane. I'm starting with bicycle wheels and a 12VDC motor from a mobility scooter.

[@The_Traveling_Clown]

I have a solar panel connected to a 12v battery for emergencies. I was thinking about a wind turbine before building my solar setup but I get more solar energy than I would have ever gotten wind. So I forgot about building a wind turbine. Thanks for the video.

[@rcubb7]

I went through a similar process and came up with nearly the same design. Ended up using blades from an air conditioner unit. They are small. But I recently realised that I could connect several turbines together in series and now can get whatever voltage I want. I still have much to learn. Great video

[@mikeoliver3254]

I would love to see you try that three bladed design again. It would be cool to see a hole series building the designs and actually graphing the results.

[@MattBaker1965]

Go for it ! Lets have some more wind turbines but less poetry please.

[@voneschenbachmusic]

Would love to see some more wind power experimentation videos, and it would be great to also have German language versions available for learning.

[@Tore_Lund]

Looks like you've got the hawt blades on backwards: The overside of the wing needs to face away from the wind, it's the low pressure side, the flat underside of the wing against the wind!

[@CajunGreenMan]

Use some of the stepper motors to make a CNC cutter, or 3D printer to create more aerodynamically efficient blades. Hope you keep working on this.

[@JulianMakes]

Very interesting! Please make some more at your parents

[@richardcunningham3022]

@The Post Apocalyptic Inventor Yes! More DIY windmill machines please

[@TheIrishdriven]

Ty these are interesting combining these with a charge regulator and battery storage would be interesting to see combination of energy inputs to a central storage that can then be drawn from

[@GeoFry3]

....and a 100 watt solar panel bought with 10-15 hours of paid work would have netted you many times the amount of electricity you would have generated from your wind turbines. take it a step further you could have bought 1 new panel a month and by the end of 3 years been nearly fairly self sufficient even with a modern lifestyle. I stopped at 6 panels myself. enough to provide power to my work shed, all electric lawn tools, and a storm backup power supply for the house. I love the engineering and tinkering of these little turbine builds (I am a mechanical engineer), but rarely do they result in something useful

[@RadioactvPanda]

Yes yes! You should definitely go into this project again! Thank you for your awesome videos!

[@king9575]

I’m very interested in you reviving this idea again, only this time you have more materials to work with then you had back then.

[@publicmail2]

Insulation is your best investment wherever you live.

[@qwertzuiopu2996]

Do it! Wir wollen ein neues Windrad sehen! =)

[@michaelbecker9166]

Would be nice to See a good H-Rotor design. You could use a hot wire of constantan to cut the airfoils. You put an airfoil (Rippe) at each end an slice the electric heatet wire over to give a perfect shape

[@FloridaGlowstickers]

The level of thick, southern USA accent in that "Now 'eres a story 'bout a man" reached Burt Reynoldian levels.

[@lowelllogerwell5146]

i would really like to see you continue this experiment!!!!!! Please do so!

[@howardroberts8722]

I love to see you compete the wind turbine

[@Sigurdinus]

You could just use the power generated to charge a battery and power the night/garden lights from it. Maybe at your parents property? So even if you cant run a microwave from it, you still see some benefits.

[@CitizenAyellowblue]

I'd be very interested to see more on small wind turbines, especially with ideas on how they could best be used for small scale applications, for example aerating a small farm dam.

[@vonries]

I am very surprised it took Google/ KZbin so long to put this video on my suggestion list. I've been watching you for quite some time as well as alternative energy solution videos. Never the less I have finally seen it. Yes, please, please, please make some more wind turbines videos. I would love to see what can be built with a bit of imagination and a good scrap yard. Plus as a parent I know I wasn't my kids to succeed and I want my electric bill lower.

[@themalic85]

would love to see this picked up again! Interested in additional power for a tiny house!

[@TheGg6422]

When you make the 3 blade design again, cover the blades with fiberglass & resin(composites are very strong & light)! Nice video!

[@TheDickeroo]

Enjoyed watching your experimental work. The fun is in the process. Once it’s been completed, the fun part is over. From a paper airplane, I accidentally invented the Kline Fogleman airfoil which employs a step or discontinuity. It was first picked up by the RC Groups and has been used there since 2006. The idea is to trap and hold a vortex which becomes part of the configuration. It has been successfully used on a Darrieus Wind Turbine. On the Improvement of Starting Torque of Darrieus Wind Turbine with Trapped Vortex Airfoil Abstract-The Darrieus wind turbines are simple in design with high power coefficient, yet they are poor performers in low wind speed regime. As a potential solution to improve the low wind speed performance, a notched airfoil (KF-N- 21) was incorporated into straight bladed Darrieus rotor and experimentally compared with conventional NACA0021 rotor from the earlier study. The experimental results displays the superior performance of KF-N-21 in the low Reynolds number without degrading the performance at the high Reynolds number .This paper presents the computational validation of previous experimental investigation and to numerically explore the two dimensional unsteady flow field over the notched airfoil in comparioson with NACA 0021 .A detailed flow characteristics are presented in terms of velocity and pressure distribution by capturing the vortex bubble formation .The simulation results shows a good agreement with the experimental data endorsing the performance of KF-N-21 airfoil for a wide range of Reynolds number.

[@jamest.5001]

Yes!!! Very interested!! I'm off grid! I have solar panels. And not the best sun! I been thinking about wind turbines. Of course I would build my own. The issue is I would have to put the turbine up about 30-40 meters! To get above the trees and in to the wind! Maybe even 50 meters high. That's going to cost right there! I could dig a pond and use the small water supply. To fill it. Then build a micro hydroelectric generator. And focus on using it when needed. To allow water to fill the pond. From the spring! I could also channel rain water from a bit if land to run in to it also. Again that's a lot of funds just digging a hole! Then how much will it generate. I'd like to get atleast 20-40or50amps at 30-40volts or atleast a few kW. From it for 8-10 hours! More when they no sun. And with rain. And if it keep raining like it has this year. It's been like a rain Forrest lately. Shame the liquid sun isn't easy to turn into power!!! So yes please!! Wind power!!!!

[@dirtybee6454]

I would love to see one work. Maybe use a car alternator?

[@fasousa4798]

90 degrees pinions and put the generator on the pole vertically like the wind operated water well pumps. For the styrodur you can cut it with resistive wire. screw the two edge profiles in wood or something not meltable and let the wire run in tension around those 2 profiles. will just need a bit of sandpaper to smooth the ridges caused by the lack of a constant cutting speed

[@AlbertLloydy]

Very interesting.. Always wanted to make a vertical axis wind turbine.

[@heckyes]

Yes! More wind generator videos!

[@wmman8256]

Your ideas are great, your definitely going in the right direction with the different models. Keep trying you will come across the right combination. You just need to keep trying different designs. I'm like you in feeling that I'll never get one that works and makes enough electricity to be useful. Edison didn't get the light bulb right the first time, it took him hundreds of experiments to get it right.

[@gabest4]

There is one more propeller type I have not seen mentioned in the video. It is probably bad, but those weather stations use it. Several "spoons" are connected by the handle and it does not matter where the wind blows from.

[@Sparkman61]

I, for one, absolutely want to see more on this subject.

[@christiangeiselmann]

One can make nice propeller blades simply out of wood. Good material for blades up to a certain size.

[@whiteeagle5969]

Generate an invisible coil around the power lines and use that as your power induction terminal

[@nunyabisnes1]

Yes, would love to see you make a new wind turbine.
