I’m so glad I found this channel, the nerd in me loves it. As a science teacher I think you would inspire so many kids to be interested in engineering etc. 😊
He already does that :)
I had an old boss who built a cold room from a basement & an Iranian wind collector, it has no real moving parts but the airflow was consistent & incredible.
I've always wanted to do something similar with a few energy harvesters built in, it'd reduce your airflow but not by enough to really matter & it'd be fairly discrete in an urban area
Not if you're using oscillation/deflection to harvest energy - put a stick the long way in your tower, tune the stick so it produces the vibrations you want, then you can use something like an LTC3588 (I've used these several times, they have worked well in many experiments) to simply hook up a piezo/strain transducer which will produce power directly without minimizing flow. In fact, you want to encourage throughflow so your source stays as constant as possible. 🙂
copypasta for the LTC3588:
The LTC3588-1 integrates a low-loss full-wave bridge rectifier with a high efficiency buck converter to form a complete energy harvesting solution optimized for high output impedance energy sources such as piezoelectric, solar, or magnetic transducers. An ultralow quiescent current undervoltage lockout (UVLO) mode with a wide hysteresis window allows charge to accumulate on an input capacitor until the buck converter can efficiently transfer a portion of the stored charge to the output. In regulation, the LTC3588-1 enters a sleep state in which both input and output quiescent currents are minimal. The buck converter turns on and off as needed to maintain regulation.
Four output voltages, 1.8V, 2.5V, 3.3V and 3.6V, are pin selectable with up to 100mA of continuous output current; however, the output capacitor may be sized to service a higher output current burst. An input protective shunt set at 20V enables greater energy storage for a given amount of input capacitance.
@@russellzauner I'm just starting with this sort of thing & I'll probably be using PC fans for now.
But I'll have to read into all that
@@russellzauner Was not familiar with that chip, thanks much for the post! I'll have to get me a few of those... That sounds like a very clean and simple way to harvest energy off vibration.
Love the idea of you researching ancient technology and perhaps bringing some new things to light! Thanks for sharing Rob, another great project!
I love this concept. Incredible. It reminds me of an old toy I had which used candle heat to spin. I wonder if heat could be applied to a stone or other surface to cause the mill to spin when there is no wind present? Maybe make the flaps out of clear acrylic. Shine a warm enough light into the system and then, boom, air circulation. :)
A thin strip of rubber along the bottom of each flap would quieten it down considerably and not effect performance (might even stop some leaks)
Something to consider would be the additional weight of the rubber strip. It would make it so that there also needs to be more air pressure required to push the flap up.
@@justinweatherford8129 You could solve this by adding the rubber strip to the panel above it. So the rubber would run along the opposite side of the board in the same place as the supporting bar/hinge. Not sure I've explained it well, but if the rubber was along the axis, it's weight wouldn't affect the flap movement as much?
Or simply make each flap one-way rotational
@@justinweatherford8129 Doesn't have to be rubber. Just has to cussion. May look a little tacky but what about a strip of bubble wrap or an old Amazon bag?
@@MrMatthewPR to get the seal he was looking for, it would require a rubber seal around the entire flap. Having just a rubber seal along the top or bottom would actually let more wind through. What I am thinking about doing is actually going to reduce the weight of the flaps by reusing scraps from plastic containers.
I'm building a powerNEST for a uni project and this channel has been a life saver. Thank you.
The fun you have actually building all these machines is a present in itself!
It amazes me how prolific this man is. Love the look of this device too.
Thank you so much for these new (old) ideas! This one had me thinking if we could turn large wall surfaces as wind generators by covering the wall with those flapping sections and directing all that wind into turbine.
Makes me think about those "zomes" (spiral domes).
If painted in black, they could make a good solar chimney busted by the vortex its shape creates.
There's a guy called Tim Hutton who made a free online tool to generate custom zome templates ❤️

@@angelusmendez5084 read something where TH-cam is going to have a way to link to other TH-cam creators. Not sure when that's coming out or what the rules around it will be
@@colleenforrest7936 possibly the new handles that are coming around November time.
@@angelusmendez5084 got it, thanks. Porn links and the like are everywhere though.
The establishment pushes degenerate things. Get used to it. We are heading into weimar like conditions
if Tom Bombadil had a workshop in his cabin , he'd surely look like Robert and his contagious inventiveness!
Sir, may God give you life, health and longevity to you and the people you love! That is fantastic idea, thank you! I was thinking about some VAWT ( with the design of a real steam turbine ) hidden somehow in a diffuser shed ( with adjustable vains) because here the wind turbines and home are forbidden. The only permanent energy winter time is the wind at all the time. That is great idea! Thank you again, I love you!
If you routed the corners and maybe gave it a coat of stain, this would look really nice. It has sort of an arty feel to it, seems easier to convince someone to put something like this in their garden than a traditional style turbine. Might be worth putting a few dabs of silicone or something to stop the wood on wood clanking.
Ply wood today is terrible compared to previous stock you would need to use marine ply or robs favourite builders board if you want it to last
yeah "his not moan comment" was ludicrous, no silent night with the current design ...
It reminds me of a Dovecote, lots of those still around and nobody complains they look bad...
I have done something similar but the “flaps” are actually on the turbine. The faster it spins the smaller the gap making it self governing. The outer cage again has static flaps that simply hide the unit and direct the air. I had a small one in Colorado that withstood 100 plus MPH winds or about 180 kph. It did not fail but simply closed itself up.
I like how you told the story to how you got to where you're at
Thank you for sharing.
I enjoy your content.
Dear Robert, it was a nice video. I started to thinking about this tower. Basically I wanted to turns the top to the bottom. The panels should connecting with a rod or wire in column. If we put a weathercock onto the top and we connect the 8 wires onto a wobling plate that is turn around the tower freely as the wind blowing. It makes the tower more sensitive to the low speed wind. So basically the panel column could open automatically and the inner flow direction could be angled to the top turbine. Another idea: we can turn the air flow to a vortex with a simple modification. The panels are could open sidely. Then the flow will twist automatically and we can use a turbine in the whole tower structurw to generate electricity. The tower material is possible made from black sintered aluminium to increase the chimney effect. And one last thing, if we have a vortex then we have a lower pressure area in the middle section. So a tube could put in from the bottom with fresh air. This tube could generate electricity too from this suction energy. Sorry, if these are looks complicated, I just wanted to write what I thought about it! BLADE
In the second idea u r basically talking about vertical axis turbine placed inside the structure that supposed to create vortex, am i right? But imo it would be inefficient compare to HAWT so ur first idea does make more sense, though i don't fully understand it.
@@yash_kambli HWAT is basically planned for opened area. But I think we can found good solution. These are just ideas now, but if lot of people start to thinking in one direction then maybe we could create something useful. ;)
Thank you for sharing your awesome thoughts and ideas in such a grand manner.
this looks like a finial
I was wondering how to make this work. Great video Robert 😁👍👍
A few thoughts:
1. The flaps could be made of fabric or film on a frame so as to be lower mass and take less of the wind force to swing them.
2. Add megaphone shaped sail on top mounted on a bearing and sealed at the small end to the tower outlet. The large end of the "topsail" would be pushed away from prevailing wind direction by any appreciable wind. Thus you get a pressure drop behind the large end of the "topsail" giving not only a larger swept area but one at a higher elevation. IF the image is not clear think of the sail as an inverted windsock with the small end anchored to a bearing around the tower air exit with a little internal framing to maintain cross section for good airflow.
A Venturi on the top with a vane to keep it aligned with the wind and the exit of the tower coned after the turbine entering in the suction part in the middle for added speed of exit...
that's brilliant
@@maw9916 Intriguing. My fluidics are too rusty to predict whether this would outweigh the reduction of post cone pressure drop this would cause. Might be down to turbine design.
@@terranovarain6570 Thanks!
Robert i have to say i for one really appreciate your efforts and they are considerable efforts, you have my mind racing every time !
I feel we are on the edge of discovery any second !
My son is also hooked, just had his 15th birthday and loves the sciences.
Your effecting the next generation and that is a life worth living.
Thank you.
BRILLIANT MR SMITH! LOVED THE VIDEO, GREAT WORK, AND INFORMATION YOU'RE ALWAYS PROVIDING! THANKS FOR ALL YOU DO!
I often watch your videos and think, man, that's clever, but I'd never be motivated to build one. This, however ... I've loved Erasmus Darwin since reading Charles Sheffield's novel about him and becoming aware of the lunar society. And I live in a windy place so ... if it works, I'm actually motivated. Brilliant work!
We have the Erasmus Darwin museum here in Lichfield, Pete. Come for a visit! The Cathedral is lovely too! :)
Good stuff for the brain as always! Can't wait to see it in action Robert. In terms of design "form" and "function" it's quite pleasing to the eye, as a hand-crafted cupola. Impressive work.
@Jeffrey Wolsieffer Erasmus, grandfather of Charles Darwin, was a physician and inventor who wrote up his ideas exclusively in rhyming couplets. He was part of the Lunar Society of Birmingham, a monthly think tank that originated most of the technologies that formed the industrial revolution. He staunchly supported the idea of evolution long before his grandson set out to gather worldwide evidence for it. And he was a pioneer in feminism, financially underwriting Britain's first girls' schools. 14 children by 3 mothers including 2 illegitimately from one of the nannies. And he was the inspiration for Shelley's Doctor Frankenstein. In every way, Erasmus Darwin was larger than life!
Oooo... I’m super excited to see the results from this particular build!
This reminds me of the wind mill from ancient Iran with air moving up rather than to the side. I love it! Thanks Rob!
Wow! Amazing how many great things from the past may still see the light of day, thanks!
Wow ! Hmmm 🤔 I’m processing. This is definitely something I want to try. Thank you so much. Your sense of humor is more nicer with this video😅
It'd be interesting to experiment with the turbine placed at the bottom as well. Because of the direction the flaps open, the incoming air is going to be directed downwards as it enters the tower. I wonder if that would have any noticeable impact on performance. Acouped added bonuses of a bottom mounted turbines would include the ability to put an architectural "roof" on it, as well as easier access to the turbine for maintenance.
Block the top off and direct the air down seems like a plan but it would lose the draw effect from the wind exiting at the top. The aero mine works totally on that draw.
@@davidsoulsby1102 Fair enough. I do wonder though if there's a way to configure the vents (with counterweights perhaps to allow them to open in the direction of the exit.
@@alantupper4106 small torsion springs might do, but counterweighting for vertical flow would require the lower weights to be on the windward side of the flow in this design. Might be counter productive unless there was a hollow bezel to house protected counterbalance weight for each vane.
Excited to see the testing for this design! So brilliantly elegant.
It is enjoyable to see a man who loves his 'work'. Keep'em coming Sir.
I love every one of his easy to understand example’s!
I love this! couple of thoughts, adding a mechanical lift for the flap opening, via a spring, would help allow more air to enter/not slow the air as much into the chamber. second instead of using the entire swept area, using a funnel or cyclone channel to speed up the air might help low wind speed performance and better overall efficiency. looking forward to the next videos. Thanks!
You could also up cycle old garden surround from landscaping projects to make on that is lighter and more weather resistant. Glue it to PVC and it becomes virtually the same with acrylic sheeting for the PVC dowels.
great history lesson and lateral thinking there Rob.... wtg. Look forward to the next step.... and, btw, you make the building of the tower look so simple.... (in reality it takes a lot of measurement and assembly skill as well as patience!).
That's a beautiful bit of woodwork and design, awesome!
Hi Rob, love that idea, great build, I know you are planning on having the air exhaust out of the top, but I wonder if it may work better if it exhausted out of the bottom? I was just thinking as the flap hinges at the top and the air will enter at the lower part of the flap, air may flow better going down instead of having to change direction to go up, however this is just my thoughts, so don’t let me change your plans, 😂 cheers 👍
Good thought.
And any machinery (turbines etc) would be below Rob's/Darwin's device and out of the direction of the wind
brilliant ....you are a true teacher and gentleman...i love the way you laugh when you find something interesting in your work..thank you sir
Many thanks!
Very energetic, I'm into self generation and consumption of power and seriously looking at wind because during the UK winter months wind is king where I live and sun is a forgotten hero. Will follow along 😁
Looking at this and all the possibilities for it's use besides energy production. If this was put on a barn and the top capped it would ventilate the barn by pushing air down. This is incredibly useful, so glad I found this channel and this video.
Has me wondering if putting a generator at the bottom effects output too.
Love this concept, can't wait to see what your results show once a turbine is fitted. It would also be good to know roughly how long it has taken you to build from start to finish :)
The time you spend for create this is depend how good you are in handwork, your tools and what material you take. (wood, plastic, thin steel or others)
remember too ,'Rob time' is different to normal human time , you need to be fuled by the right mix of tea ,or char as it technically described , a bit of nicotine ,and whistling apparently helps too ,[ gas laws apply here ,O2 uptake etc].so double his time to get a realistic normal human chronological expenditure .
@@scantrain5007 yes, sure it depends on availablity and expertise.
Can't wait to see this in action. If it's profitable, I'd love to get one.
What a thoroughly fascinating and inspiring video Rob, can’t wait to see the next stages. Just a practical thought, it could be noisy so maybe some form of damping perhaps a strip of silicon along the edges that strike the structure. Taking care not to create an air gaps.
I was blown away when he took the fan, pointed at the tower, and the louvers moved.
Thats a lovely piece of work as it stands.well done.
Thank you! Cheers!
I live in an area of small properties, but a lot of wind and I've been considering a vertical axis wind turbine as one source of power. I look forward to the follow up.
Just found your channel, this particular video is the first I have seen as it happens. Subbed immediately, I like you and your content!
I have a lot of time for people who are willing to get practical and hands on when investigating a subject.
It's so easy to use your amazon link and it cost me nothing , but I get to help you. So GOOD . I'll use it and book mark it now.
can't wait. never heard of or thought of this. thanks for digging this up.
Thanks Robert. Definetely inspired. I'm thinking about sites on the roof to place one of these beauties!
You Sir are an inspiration for the motivated. More power to you Sire. Wish u and your family Health Wealth & Happiness. 🙂
Look really forward to seeing this working Love the idea!!!
Oooo I'm itching to see this finished, love ancient technology refined with today's technology
Oh my, I am truly impressed. I've never thought of a modified Bernoulli effect. A ten foot+ tower placed between two homes where the wind is funneled with several generators inside would be a fantastic battery system charger. Needing two sides with flaps only. The two sides would be blocked by houses ... at least until you get to roof level. Thank you for the innovation idea. I'll put it on the list and if I live long enough to finish out my other projects I'll look at it further!
I love to learn,,thanks for the brilliant and inspiring videos Robert.
Seems like a 'whirlybird' style attic ventilator on the top would also add to the airflow influence, as well as being a foundation for the turbine armature. As opposed to a swinging exhaust vent that would always swing to point downstream of the wind.
Beautiful build! I can imagine songbirds trying to land on the open slats and being pulled inside. Might be a good idea to wrap it in wire mesh to be safe if it’s going to live outside.
Hi Rob,
that's a phantastic system! Many people are against wind turbines and argue with killing birds. With this one the risc of shreddering birds is minimal. Aditional it looks better as a boring rotor. WAF = Women Acception Factor.
Great!
I think you really cannot overestimate the importance of an alternative energy source looking like an architectural feature rather than some strange thing the neighbors won't understand and would likely complain about. I think this is truly genius for that reason because it does look like a beautiful architectural feature.
I'm looking forward to seeing the next stage, when you add the turbine..
Absolutely brilliant, wonder what it would be like if the flaps themselve were all rows of speakers/wind generators . Great stuff 👊
Good Idea. Complexity in the form of moving parts has problems. I love your simple louvers. Also, no one will object to the esthetics.
i love your videos. there is plenty of good inspiration. I'm going to start making a wind turbine myself and I'm now in suspense whether it's going to be one like this I'm going to make or an ordinary one. it is made with a segboard motor. greetings Steven from Denmark
Now that is absolutely genius, and so simple
Wonder how much "draft" a simple chimney creates on it's own? I remember as a kid feeling the suction on the flue hole in the middle of our blocked up fireplace, when we took out an old fitted gas fire.
That's a brilliant idea and aesthetic enough that the missus won't mind👍 This might solve my issue of being too sheltered from the wind, redirecting all of the crosswinds created by the buildings and trees might get the generator spinning properly.. I think because of the crosswinds created the wind generator ends up hardly spinning, I was gonna put some kind of spiral sail around the pole to catch and direct the wind but this looks way better than what I was thinking of👌
Very cool project. Like it very much.
IT'S GOING TO BE A THING OF BEAUTY! CAN'T WAIT TO SEE THE RESULTS.
Wow…thanks so much. Fantastic video and subject.
Great content Rob, looking forward to the progress in the following episodes. ( Just to add - the price of wood nowadays - crazy !) Regards
yeah it is getting crazy expensive!
That's just brilliant, I've never seen this before, im going to be following this build close, im verg interested 👍👍
Hope you enjoy it!
Very nice, i wander if flaps are made not with the mass so excentric to the pivot point will reduce the minimal speed for wind to start.
Hi There you might what to take a look at the old turret type ventilation units on old libraries and warehouses. They draw the air up inside them vertically and usually have a chamber up above them which is only open at the bottom. This void creates additional negative pressure which increases airflow.
Kind regards T 🙂
Are those the things on top of the English parliament? (Genuine question, nothing to do with the escape of hot air from the chamber 😀 )
love this robert and makes me think about maybe incorporating a tesla turbine on this as you already have these and you could converge the output directly to the turbine and then see what the results are? might be a simple solution as a converging shroud would be easy to make imo the diverging part is being done already on the volute of your TT ...
I love it when you laugh like a kid playing with a toy ! Just part of the charm of your awesome channel!
it's not my idea I am just copying someone else - it is just plain awesome when it works
I grew up close to the potteries (Stoke on Trent) and can remember seeing something like this on an old building when I was a kid. I can't be certain of exactly where it was or if the old building I saw would still be there. However, I think it may have been something to do with Trentham Gardens, but I can't be certain of that.
Hi Rob, I'm glad you've brought this up again. I have been drawing up some ideas to make a little group of them, as I have a pretty draughty garden and I, like you, am all for some value added, why not cover it with the Electricity from the rain idea. Just a thought, keep up the good work Mate
nice one mate - cheers
@@ThinkingandTinkering to adding optimal value to this I was thinking about a wind turbine powered car they tested a few years back that went faster than the wind speed by using a sailboat design that hits the wind at an angle increasing the lift an reducing the drag. They had it geared to the tires what if you had multiple fans/generators stacked geared in sync with that sailboat design blades in that tower, by theory once you get the bottom one moving the optimal speed the gearing to the next should start to pull creating suction to the first and in series the next even more an so on creating a self driven wind tunnel pulling the air from the sides an out the top once started by the wind. Any thoughts or holes you see in this theory?
Robert love the video as always however making airfoils is actually very easy. Talk to someone in the model airplane community, there are databases of any airfoil you can dream of hot wire some out of foam and laminate with some fibreglass done.
Another masterpiece 👏🎉
Love that one. It’s an architectural feature indeed. I wonder if one could use the motion of the “flaps” in itself to gain a little extra electricity.
Could a pivoting venturi/flow suction structure be added on the top that would utilize the airflow above and over the tower to suck air trough the system increasing airflow or even just to reduce the energy lost on opening the flaps?
Also, would painting the side facing the east, south and west black maybe cause some heating and therefore air rising in the system?
So many ideas in my mind for this tower :D
How about a venturi/spiral center rod to direct and concentrate the incoming flow.
INFINITY LOVE X A TRILLION TO ALL BEINGS ...........GO GO GO ROBERT KEEP UP THE GREAT WORX💙💙💙💙
That’s interesting. I live in a very windy area and needed a vent cap for my methane powered hot water heater. I found one made by Duravent that would generate a suction in the vent pipe when wind blew across the vent. The part is 6GVVTH.
Great video as always mate. There are many "lost" or "forgotten" technologies, especially when it comes to energy. Just be careful 🤐
It would be very interesting to see how it preforms! If you would try adding a turbine, it would be much appreciated. Thank you for making videos! Kind regards from Denmark
Pure genius! I love it and your's doesn't look like some industrial eyesore.
Hi Robert, I am glad, that I fond this Video. I enjoy watching your clips.
Do you got an idea, when you will be able to introduce the Turbine to us?
Greetings from Germany
It's a stunning wind chime at the very least mate
I made a small one of these once. The pressure and direction of the wind would push the flaps at the bottom down (the exit was at the top) maybe this won't happen at a larger scale. Assuming it does I have thought of two solutions.
1. Give it tall legs and allow air to vent from the bottom. This way the pressure will aid in pushing the flaps WITH gravity.
I'm not fond of this idea as much as it requires it to be tall and less safe as someone could go under and stick their hands into the blades. Also, back pressure from the ground may be an efficiency issue.
2. In the original design,(1:55) we see the flaps are flapping upward and are closed not by gravity but maybe wire with weights pulling the flaps closed. the weights would be just heavy enough to close but light enough that even a slight wind could blow them open and closed on the other side. This makes sense as the materials back them may have been heavier making flapping harder? The weights would fix not only the direction of flow but also allows you to use heavier/ cheaper materials.
After some thought: I don't think this is much of a problem on at larger scale. The benefits from 2 are likely too small at a larger scale to matter. Will play around with this anyways so things like steel can be used. (wood looks soo nice though!) the design in the video seems to be the best.
This is amazing, truly!! There is Soo much that can be built on to this , so much more it can be, amazing, thank you!! _👍
Glad you like it!
Multi directional and good looking. The flaps closing might keep the neighbours up lol
Lovely Build. I'm kinda tempted. It could also keep back thieves from a garden vawt.
Hi Robert, just in case you did want to explore the aerofoil build in the future, have a look at flight test YT Channel (model aircraft building using foam board). You can knock a basic aerofoil shape up in minutes and for pennies, all you need is the board, a sharp knife and a hot glue gun👍
You are going to show us fitting the turbine and all aren't you, please? I have all the materials. Love your videos soo full of enthusiasm and good solid sound facts and very important for those of us who want and need to know! Thank you.
Remember to factor in entrainment for a perfromance boost at the edges of the turbine blades, to optimise available enrgy.
Robert , was it not what did the Commandant Cousteau with his Calypso 2 .
What I remember was there was a huge tower in the middle of the boat , with different opening along the side .
Inside was , what I could make of and read about it , propellers pile on the top of eachothers , like a vawt, turning at different speed .
Harnessing all the different speed wind at the same and transmitted on the axle .
Great video! Great idea!
Check out the desert city of Yadz in Iran where air temps reach 40 degrees C throughout the summer months. Many buildings utilise the ancient passive technology of "wind catchers" to cool buildings. Some scope for adaptation to power generation using a fan or a peltier type device.
Cool idea from old forgotten tech. However, the principal is very different from the aeromine. I like both ideas. subscribed.. I like that you tickle the few brain cells that I have.
Just a few thoughts on improvement. At the base at the bottom if you could build an inverted funnel so that the air coming in has less turbulence and is more directed Up. And then at the top you would need to have a similar funneling. Your top board the hole is smaller than your octagon so that that distance from the edge of the Octagon to the edge of your swept area is going to be turbulent and wasted energy. So if you extended the tower up a little bit say a third do a half a meter to allow for a bit of a funneling from the edge of the Octagon to the swept area you would be more efficient directing that air through the turbine you'd have less turbulent air travel in the vertical shaft. I really like your mock-up it could go outside and go to work with just a little bit of all weather protection. If you were to make this for actual production I would suggest something less than plywood for the flaps maybe some diff plastic flaps it would be lighter. And and if it was to go into production, all the flat seats would need to be able to seal as the flap is in the closed position to reduce leakage. But overall I absolutely love this idea thank you so much for presenting harassment Darwin's work. You did a great job thank you again.
Looks like a really big version of the non-return valve panels you see over air vents, which does make me think this could be relatively easy for someone to 3D print a version of it. Stacks of panels in parallel connected to an inline turbine like the thing you were blowing with, but rigged to run as a generator instead.
Fun how just a bit of simple mechanics can work wonders.
I saw the media hype too lol, but a thought on your impressive build, if the spindle was positioned a 3rd of the way down of the one way shutter/dampers with a small weight fixed to the upper section then the air pressure to open would be greatly reduced.
