One of the most genuinely authentic personalities on TH-cam. Also @Robert Murray-Smith, I don't know how in the world you are able to create all of these content rich videos and still continue working on all of (I'm sure) amazing research. 👏
No kidding!
One video at a time is my guess
oh wow - that's really a kind thing to say mate - thank you for taking the time and trouble to pot - it is much appreciated
Kudos for owning up even for an honest mistake! That's what viewers really appreciate =) Great work as always.
cheers mate
Almost hypnotic watching that turn in the wind. lol 🤣
I agree I was there for quite a while watching it lol
Thanks so much Robert. I made the Ugrinsky turbine last night out of some old scrap. Amazed how well it works in low wind speed and put it up on my TH-cam and Instagram account. People are loving it! Love the channel and have made a few turbines out of old motors based on your excellent tutorials. Keep up the great work :)
I love the innovative direction these wind turbines are going
Thank you for the video
cheers mate
Well done Rob. Seeing the original Ugrinsky, only the drongos and dipsticks would assume you could not do it by hand :)
yeah pretty. much mate lol
Sir, with all that you have contributed to the worlds knowledge! IMO no apology was ever necessary. I in awe of the balance you did on this build. I fully understand the materials used, SS 'cause it's what you have, bolts for a prof of concept, etc,etc. Once again I look forward to seeing the next build. Cheers!!
cheers mate and thanks for taking the time to post
The roof mounted version may well double as an anti pigeon roosting devices .. a super useful bonus feature.. Love all the stuff you produce Robert and Luke much appreciated
Automatic pigeon plucker.
@@jerbear7952 Nice idea, add some spikes for good measure
lol -cheers mate
Yeeeah you could hook a pir wifi camera up there to watch pigeons being mashed on your phone while your out and about ?
i.e. while your at a wedding, sky diving or at a funeral ?
We’ll let it slide this time but don’t let it happen again! 😂
When you said paper thin, it made me think of “tensegrity” systems and I started wondering about using rigid ribs or spars and soft materials like sail cloth for the webbing between. I’ve seen small axial turbines with cloth sails and flexible spars. I seem to remember it was somehow self regulating too.
I'm thinking Valink Plastic Fencing covered with old parachute
good idea mate - want to pursue it?
@@ThinkingandTinkering maybe one day. I have a workshop full of unfinished projects to take care of first.
Yet another brilliant piece of Tech every video from you is a Gem thank you very much.
wow - cheers mate
I find it interesting how easily people can integrate 3D printing into projects that are made from mostly non printed materials. The printed parts are often under spec, but they are a great way of bridging the manufacturing gap between sheet fabrication and machining or more advanced forming!
I agree
Well done. Well done, indeed.
cheers mate
Love the idea of using the lift from a pitched roof on the apex, especially in coastal areas where it would help with seagull culling 👍👍👍
lolol - yes it would!
I understood your meaning. I have many 55-gallon drums and am fabricating a poc now.
You're a good guy Robert! Stay awesome out there man! 😊🌎❤️
wow - cheers mate
One can begin to aproxinate a spiraled ugrinsky turbine by stacking 3 or more ugrinski turbines, each advanced or lagging the one below it by (360 degrees)/(number of turbines stacked on the axle).
There may be an advantage with a spiral like design if there is a lull in torque at certain angles to the wind.
nice suggestion cheers mate
Terrific proof of concept.
cheers mate
Very interesting to see a multifaceted approach for renewables installations.
Cheers!!
cheers
No apologies necessary! Great alternative method!
Thank you! Cheers!
Lovely build that Rob
cheers mate
Sheet aluminum was my 'knee-jerk-reaction' since its very common.
I have a 24" roll of it laying around here some place which I originally got for building a shroud for my truck engine.
I ended up deciding to use a fiber resin assembly instead, therefore, I still have it for other processes at some other time, but it would certainly work for something like this.
it certainly would and it is easier to work than SS - quite a lot of spring in SS but the Ali would stay formed
Hi Rob. I use pla+ and petg filament for my projects as abs can be a pain to print. Petg prints at 230c and I have had small windmill features working in all weathers for over 2 years without any problems. Keep up the Great work. Trev.
Videos posted or it didn't happen. Joking, of course. But, do you have any posted videos? I'd love to see that. I'm wanting to build a miniature wind farm of small profile, unobtrusive wind generators and have them connected to a battery bank for future use.
Yup PETG is the way to go for outdoor applications. Any favorite brands?
ASA preferable to ABS outdoor, inherently UV resistant. Petg is good as well only sometime downside is it's a bit flexible
nice mate and thanks for the advice
I absolutely love this channel, your enthusiasm and the knowledge you share. Thank you.
cheers mate
Don't be sorry mate I understood the helix version perfectly well your an amazing guy and TH-camr! Thanks for showing a simple standard version 👍🏻
cheers mate and thanks for that
I get the impression a fair number of Rob’s watchers are waiting with pen in hand to find that “got ya”!! Moment.
Thanks for all the free knowledge Rob! Even if people get totally lost in semantics
yeah there are quite a few like that - but most folks are just plain awesome !
These models look quite nice 👏
it is pretty and robust!
this is what england was famous for thousands of manufacturers in sheds that fuelled large production companies always a pleasure to watch
Thank you sir.;-)
you are most welcome mate!
Ooohhh shiney!!!! I like it. I bet that really hurts if you catch your fingers in it.
saves you having to attach razor blades all along the edges lol
Great build! Bolts?!? Getcha a rivet gun!
lol - very fair point mate lol
Really enjoyed the video like always! Keep up the good work!!
cheers mate
If intending to use in that orientation on a roof, I think it'd be a good idea to take it back outside and gently pour some water in it, those curves look like they might hold some water in making it much more difficult to restart after rain until it's evaporated. Though if you find it does, drilling a couple of small holes at the then lowest points would enable it to flow out, with hardly any effect on it's wind efficiency. Not something you want to be doing at height if it does need it ;-)
Put a small partial covering over one part, angled to shed the rain on one side and you might have yourself a slow water wheel for non wind but rainy days too
good point mate- cheers
Another possible efficiency thought, for roof mounting in that configuration is , rather than the most natural way to think of mounting it, directly on the apex, as the roof is sloping you could mount it slightly offset, and lower, on the downwind side. That way the wind deflected by the roof will be directed to the scoop side ( presuming the device itself it designed to turn "top away" from the wind rather than "bottom away" ) and shielding some negative torque from the return side. A good way to test the optimised mounting position, on the ground, would be a sheet of plywood set up in front at the same angle as the roof is.
For what it's worth, a lot of my thoughts come from thinking/accepting how most designs have already been optimised for a general situation then looking at a proposed situation and thinking " how does this differ from the general sighting and how does that affect things?" From there looking at which general solutions optimisations might actually detract from the specific one and is there anything that would normally detract if used for the general one but could be used positively for the specific one. I guess "optimising something for it's specific use" might be the quick way of summing that up.
ABS is harder to print large parts without warping - though if you persevere, perfectly possible to get as good results as with pla. Higher temperature tolerance can be a benefit.
cheers mate
Cheers brother
right back at you mate cheers too!
Robert, why have you left the gap inbetween the two sheets open at either end? Would there be anything to be gained by making the sheets longer so they join together and leave no gap? It might be more aerodynamically efficient. Openings and sharp edges are usually inefficient.
Wow, I can remember using dichloromethane when I was in school to glue the seams on a plastic box I was making. Not one word of warning given back then!
I still use it devil may care - I will pay for that at sometime in the future lol
Since it has four surfaces(inner 2, outer sides) I would think it would do very well. More surface area equals more torque. Very nice! Thanks Rob!
cheers mate
Extremely interesting and promising. Does the wind also travel through the center gap ? Just wondering if it would work with the center filled in. I'm going to have a go at making one as I like the idea that a vertical one can pick up the wind from all of directions.
let me know how you get on will you - it is just not possible for me to test everyone's suggestions and I would love to know - cheers
If you put a funnel over it that horizontal ugrinsky turbine looks like it might also function as a water motor. 👍
It’s basically an Archimedes’ Screw without a tube.
it does indeed
I could make the original blades with some construction foam, a couple wood templates, and a hot-wire cutter. You'll need to cover it with plastic wrapping.
MeCl2 is also used in paint stripper. (use adequate ventilation!)
I like that! - that is an awesome suggestion cheers mate
nice ...i think its good to try some gears and chain to make the motor speed up a bit...cos the torque will be high due to a good storage of wind inside the blade...it will increase the voltage or amp...other wise the motor will even not light up a single led
cheers mate
I can finally sleep, with that apology out of the way 🤣
lolol - glad I helped lol
You need ASA filament for outside use as ABS is not UV resistant
I loved the old enamel ESSO garage signs in this style.. I would love to get one
they are awesome
@@ThinkingandTinkering Agreed
Might be able to make one without a 3D printer: 🤔 maybe use tissue paper walls and put a small twist between top and bottom templates, then layer thin layers of spray on clear coat letting each time to dry before the next. Just thinking out loud.
Great vid, thanks for sharing! ✌️
worth a try mate -let me know how you get on will you?
Great stuff as usual Rob, thanks..... Q - in your opinion which would function better the twisted or the original?
I'd love to see a 100% cut and bent sheet metal version of this. Ideally the joints could be filleted, formed by gently curving overlap of the sheet that has been soldered together.
that would be pretty
Dude don't worry it's no worse than a typo please have a good day keep up the informative videos I love getting in my video feed hope you Brits are doing well staying away from that covid.
Literally what I had in mind. Just use this, start a local company and start putting it in the roof. I do not like the original design of Roof Ridge and thought this is better. Also was thinking about darrieus wind turbine with some guides for the wind, but ugrinsky is probably more effective
no worries. your good out weighs an oops and your make a mends is awesome. great work
cheers mate
You have to work more than one dimension simultaneously or plane of existence for excellent results.
How many axis can you work at the same time, with the same energy is the secret, in my humble opinion.
Wish I’d taken that Job Rob...
job? what job?
I think that design is safer then the current wind turbines blade designs...should work well on the beach or sailboats.
I think so too
I really appreciate your honesty and helping everyone figure out the possibilities. Thank you. I have a question. The area in the middle between the blades, is it possible to incorporate a bend, shape, or hole, that would cause the Venturi effect and assist in the rotation speed of the turbine? Thank you again. I apologize I have a lot to learn.
Having a lot to learn is no cause for an apology.
Being unwilling to learn is cause for apology.
Keep asking questions.
😉😊😇
I would think it is certainly possible to bend the side plates to create a Venturi
enjoy all your videos , great information..... was thinking .... what if a test could be done , where the frame also got as equal scientific and design attention as the spinning part - maybe efficiency could improve ? smoke machine and an angled plank ?
that is an interesting thought mate - fancy giving it a go?
Were there any bearings used with the axle in that prototype?
Presumably the twist leads to a more continuous power output as part of the turbine is always head-on to the wind direction.
Yes, but it takes more wind to start.
I assume so
I believe an issue with this horizontal version will be it has to overcome its mass in the vertical plane, so the bigger the sweep the more energy required as you are lifting the mass, in a vertical version with the horizontal motion the bigger the sweep the easier it will turn. Obviously its comparing 2 ways to mount the same turbine.
A covered version which funnels the air may increase the local energy but takes up space were more vertical turbines could be fitted.
This is all straight off the top of my head so testing would be needed to confirm it.
I'm thinking thin bladed, tightly packed vertical would give best output per meter...
????????
it would also acts as a fly wheel though - so in my mind what you give up for starting torque you are going to gain in even output - I strongly suspect in over all performance orientation is going to have little impact but I think you are right packing density will
What if you made shorter versions of this turbine and arranged them in a spiral pattern, similar to your 3d printed spiral variant? Some kind of output efficiency testing would be interesting to see. I believe both spiral variants would offer smoother rotation although I won't speculate differences in efficiency.
Wonderful content Sir. Really appreciated. I'm a new follower, unable to find low friction, low rpm but high current DIY generators on your channel. Kindly guide me if I'm not able to navigate to correct playlist or section, on your channel. Cheers. Thank you
Imagine that thing flying off in high winds 🤣
like a rotating blade set the damage would be worth a B rate horror movie lol
Lord help me. Some " Dear BBC why oh why " types have their knickers in a twist.
If you blocked the top at an angle directing the wind down it would do much better
Robert, I found a 2018 video of my dual counter rotating shielded vawt. its up on my youtube channel now.
I like the looks of the helix better but that one would be much easier to build. Thanks Robert
I agree mate
ABS will degrade pretty quickly in UV light outside won't it? Have you considered printing with PETG? It should last a lot longer especially with the proper coating.
It is a kind of ventuti shape😁moves more in centripedal vacuum I guess🎢🤗🤗
I guess so
Good video
cheers mate
Sounds like a minor mistake. But willing to correct yourself is a quality to admire 👍🏆
thank you mate
Hello, I am assuming by the way you were holding the wind meter and sitting that the wind was coming coming in from behind the the camera. I was wondering if there would be a performance difference if you turned the unit around to have the wind entering the opening at the top?
probably not mate - but I can certainly try it
looks pretty cool !! ha..ha.. looks very efficient !! super duper!! good luck !! no need 2 apologize? I haven't had my cow!
I'm sorry no1 gave U any ball bearings!! U could also make it from dowels, & trash bags!!
lolol - yes you could! awesome thinking mate love it!
Would you put this in the Darwin's Tower?
What About Archimedes' Turbine?
You could use the Metal for the base and 3D printing the Tip.
I was thinking about the archimedes turbine for sure
Reminds of the things shops like newsagents used to have outside their shops in the High Street. 😂
it does doesn't it!
Robert, if'n you got kid's or grandkids running about the garden on a stormy day would you want sharps disintegrating or some nice blunt pla when it collapses? and the double helix looks so pretty, I'd opt for the loss of perfomance. Only saying.
lol - I hear you mate
Why didn’t army’s invent the windmill winding flaming bomb thrower ? Quicker reloading on a windy day , compensate for drift ,
lololol
Love yer vid as always m8 thanks for it
cheers mate
Is there any way to limit the rotation speed? Typically there is a governor (of some sort) that changes to blade pitch to reduce speed as it gets to high. With the fixed blades of a Ugrinsky, I am unable to figure a simple method out. BTW, I just started watching/reading, so I apologize if this has already been covered.
Really interested in the roof ridge installation proposal, would your twisted design work in the horizontal plane?
it should - still to check that out
So if it is roof mounted horizontally doesn't it become very wind directionally dependent? I thought one of the purposes of this style of turbine is that it is not dependent on direction. ( not trying to knock the thoughts here, but am I missing something?) Wouldn't it be more efficient mounted vertically? Catching the wind from all directions? ( I do love the videos and your thoughts on things. I like how you make things from odd bits!)
don't forget roofs act as something of a wind guide
Imagine if we built the fins out of a flexible solar collecting material.
nice
I want to see how much power this size can physically produce.
Also, how do you stop wind turbines like these from destroying themselves in high winds?
you can always brake them electronically - it's pretty simple to do - just short the generator and it will act as a brake
@@ThinkingandTinkering So basically the same as any other wind generator.
I thought that maybe a small one like your 3D printed demo, if built with solid material, would be able to withstand stormy winds without any speed control.
Could you add a Magnetic levitation bearing on the sides? Would the metal interfere with the magnets?
yes but it would complicate things for not much advantage I my feeling
the shape looks like the fibanocci spiral shape on the 3d printed parts, is it the same?
I don't think so
I would love to try to weld that SS on 10amps with my tig
10 seems a bit low to me mate - maybe 50-70 on thin steel?
@@ThinkingandTinkering 1mm I use 20amps on my tig. You would just blow holes at 50 on that thin gage . I challenge you to have a go on your mig or stick and post the video for a laugh.
Maybe even a short mate
Pleassssseee
It seems almost like it would be cheaper and easier, by the time you built anything that would generate a sufficient amount of wattage, to just buy the printer. Plus you have the benefit of owning a 3d printer.
What would that printer you have retail for? I have kinda wanted one for a long time.
about US$230 I believe
if it is very well balanced then the extra weight just helps it be a flywheel
absolutely
Could you make them out of aluminium/tin cans with the tops and bottoms cut off and cut vertically?
if you can get the shape - you would need a set of rollers but once you had that - for sure
@@ThinkingandTinkering i meant cut both sides vertically making two U shapes that can make an S.
Noyce one. did you take the 3d printed version any further Mr Chuckle ?
Where do you get your "builders board" from? my search for it only brought up signs and floor protection.
we have local shops that sell it - you can't it direct form eurocell or just online but if you are in the USA it is much more difficult and expensive to get - here in Europe it is about the same price as wood and as available
@@ThinkingandTinkering Thanks, I'm in Shetland We have a homebase and Jewsons but that is it, I have to get most things via the web.
Buildersboard , with its hard UPVC layer on foam seems to be an UK specific product. Google only shows some trade asscoaitaion, no product, or even brandnames, so get us some company names, please?
which is more efficient, the twisted one or the flat, or are they about the same.
I would think the flat would be less consistent motion but is there much of a difference ?
I would imagine they are about the same
Hi I'm looking for a video where you have kegs(containing some working fluid) on a wheel which are heated causing a state change causing mounting wheel to spin. Can you enlighten me?.. or maybe I saw it somewhere else. Thank you!
I have seen those - they don't work particularly well I believe
👍
Don't be daft, no apologies needed. Cool to see an alternative though!
cheers mate
flywheel!
yep
Make an inner “wall” to put metal in between, won’t need tape?
cheers mate
I wonder if people actually are capable to put pics with what they hear and see. Odd really, I could possibly have a longer rant but not worth the time.
Keep up the good work work sir. 🎉😂😂
I wonder too mate lol - cheers
What about cutting the parts out with a CNC? All you need is the file of the template. Of course, you have to actually have a CNC machine....
you do need the machine but then yes more than possible
I can't seem to find a video of the gasifier in operation, what number would it be, Please?
I'll look it up
I've never heard of builders board, (in Canada) Does it go by another name?
Dumb question time: If you block the side of the rotor that is pushing against the wind (Bucking wind?) with a static shield, would that help in any useful way?
Yes, it almost doubles the power. It's called a "Shielded Savonious".
I am not sure with this type mate - but i suspect not - but i will need to read up on that a bit
@@justtinkering6713 Thank you. I was thinking about that looking at a vetical axis rotor based on a 55 gallon drum. But it would have to turn with the wind direction, like a weathervane, which was my stumbling block. But something like this, which is stationary, might be well served by such a contraption.
Now that I think some more, I wonder if the back-side of the shield would block the exhaust of the wind-filled scoops
i don't think that is right for this type of turbine mate - i am not sure as i haven't checked - but - without meaning to be rude here and i am sorry if it comes across that way - i can assure you i don't mean it to be - i get the sense neither have you
