@@ThinkingandTinkering you could combine screw like rotor, from some of your previous videos, with this but in opposite direction and with different casing that will collect wind from the screw like rotor and transmit to this jet like turbine. So wind goes up the cone not down the cone. And you could put this your Darvin turbine around screw rotor but not all the way just with the point of connection with this jet like turbine and between them you could put real tesla turbine in a way that air that comes out from the tesla turbine get into this jet turbine, so this combination will suck the air even faster from tesla turbine wich will increase torque.

[@tomscott1159]

For many years, sailors have used a wind catcher to funnel air down through a square deck hatch. If you sew a triangular fabric panel with a base width about 2x the hatch opening width, then pull the apex up with a halyard and attach the base corners to two adjacent hatchway corners, you have an efficient catcher for wind which blows over the catcher-attached side of the hatch. If you replicate the panel with another, attach its base to the two opposite corners of the hatchway, the apex to the same halyard, and then sew the two panels together along a vertical line to form an "x" when looking up through the hatchway, then you have a catcher which works fairly well in all directions. A sailmaker could help you shape the panels to encourage efficient vertical airflow.

[@matheusfaria7230]

6:35 That's very interesting because the warmer the generator gets because of the friction the more air it would draw because of the stack effect therefore using the wasted energy as a way to generate more energy. I wonder if enclosing the rotor, at least slightly, would increase efficiency because of the venturi effect.

[@colleenforrest7936]

If you want it to get warmer, paint it black or use black filiment. Need something other than PLA to keep it from melting though. You can also use the PLA as a sort of lost wax casting to make a stronger final product. There's also filiment with a lower melting point.

[@ThinkingandTinkering]

I may well do mate

[@geoe5621]

Not only that, but I think their decision was also based on avoiding water "collection" towards the bottom of the unit. I think ventum dynamics are onto something "big" - and Robert as well. Ventum is working on a "home" "Ikea style" version - but an open source alternative is always great! :)

[@matheusfaria7230]

@@geoe5621 Yes, when I first started watching the video and the machine was upside down I thought it was just a cool normal project but when I saw that picture showing that it's actually the other way around it instantly triggered my interest. I do believe that even if his or their design doesn't work the concept itself is really future-seeking and things should be developed trying to follow it... Turning air energy which is currently something "temperamental" into something stable and predictable, even if extremely less powerful, would already change the world. Another huge factor is that this type of design doesn't seem to disrupt the enviroment and also wouldn't need the costful maintenance that current turbines do (that's their major deterrent)... Make it work and give them a magnetic bearing and you have the next-gen power plant.

[@terryfogarty5076]

The cone/rotor piece took me over 2 days to print, but I'm loving following along with this build!

[@hughjardon3538]

Torque is directly proportional to current in a DC motor or generator. Voltage means nothing, though you can use it to calculate power when you know the current. To get the current, you must load the generator to make it slow down. There will be a speed under load that gives maximum power. You must apply different loads to see what that is.

[@feras5017]

A variable resistor may work? And the fan should not be held by hand, it shkuld be fixed in a position to make sure that you have same angle of attack and distance between the fan and the generator.

[@ThinkingandTinkering]

then you would just be measuring the generator

[@hughjardon3538]

@@ThinkingandTinkering The only thing you need from a generator is watts. The question is how many can you get at typical wind speed. For that, you can simulate the wind with a blower, but then you must load the generator so that you know how much current it can make at that wind speed, then you can measure the volts at that current and calculate the watts, or connect one of those cheap Ebay watt-meters that give you it directly. When you load a generator, the torque to turn it increases with the current, so it slows down.

[@ebaab9913]

I do agree about watts/windspeed being the ultimate measurement. Also it should be in the natural environment and not a laboratory. History also should teach us to stick to AC. One point that I noted about the shape, the vent holes come out where they could affect the wind flow escaping from the tower, if they pointed down, the wind flow would provide more suction. This is another reason to test outdoors.

[@ThinkingandTinkering]

wow cheers mate

[@moviemonkey9]

Love what you're doing - some thoughts for improvements 1. If you undercoated and painted the funnel inside surface it could be made smoother and therefore air would flow cleaner. 2. Could you add a hall effect sensor to the shaft that way you could measure rotation and therefore be able to compare rotation and generator output with each change you make. 3. The holes around the funnel base, if these could be made larger (maybe every second one joined) to ensue the used air can excape and not create any back pressure I'm playing with the idea of adding some of these to the roof of my RV to add another source of power to my batteries

[@marcothehammer]

I'm currently living off grid in my tiny RV. Currently, it’s parked in the equipment storage yard of the construction company that I work for. Allow me to comment on your proposed modifications... 1. I'm not certain a smooth surface is the best treatment for this situation. It makes sense but consider the effects of the dimples on a golf ball as well as the wind tunnel studies by NASCAR racers in the '60s that brought vinyl tops to the automotive industry. Perhaps some spiral-like veins in the ‘funnel’ area could improve airflow and get it headed in the right direction? 2. This is a great idea at first glance! We would have to consider the potential of the power drag and calculate it into the final equation, but I imagine you already have this in mind... 3. I concur! This was the first thing to come to my mind when near the end of the video Robert Murray-Smith asked viewers for suggestions about improvements. Perhaps fewer vertical supports could be used if designed with the most aerodynamic friendly specs or simply changing the shape of the exhaust ports? I live about 35 miles South of Seattle WA and we don't get as much usable sunshine as other areas so the idea of mini wind powered generators is attractive to me. Maybe several small units could be ganged together for better performance than a single large unit? Some individual units could also be able to continue generating power if one unit was to fail temporarily. I use a ‘SunGoldPower’ brand 3Kw inverter/charger/PV controller without any solar panels up yet. I have two 24-volt 320-watt Renogy solar panels standing by, but I know I’ll need several more to collect the 2.4K watts that I typically use daily. Currently, I have two 24-volt, 100 Ah ‘Chins’ brand lithium batteries that I take down to about 50% daily to maximize their lifespan and I re-charge them to 100% daily. I’m happy with their performance so far. The ‘Chins’ recommended charging rate is limited to 40 amps. I have a Westinghouse dual fuel I use a 3650-watt propane fueled ICE generator with wireless remote control that makes using it during our longer than average winter and wet weather easier than going to start it outside. It takes about 2.5 hours to re-charge the batteries and so far the cost of propane fuel (without road taxes!) has been reasonable.

[@TheGazmondo]

A great experiment! It would be interesting to do a simple wind tunnel type experiment with some smoke to see how the louvres on the wind catcher performs. Whether the air passes by or effectively directed downwards, in which case some vertical baffles could be added to the curvature of the cones? Keep going, can’t wait to see how it develops!

[@asdfdfggfd]

I have a rooftop in the city that because of the microclimate and turbulence is subject to sustained extreme high winds. (greater than 100mph, according to roofers) I need to do masonry work every year because the wind scours the brick and mortar away. A turbine for these types of conditions would be very interesting to me.

[@rickdworsky6457]

Just measuring the talk alone doesn't tell us everything we need to know. If the starting condition is very windy, then of course we will get much talk. What we need to know is the efficiency of converting that windiness to talk. I believe Robert's performance is optimal.

[@UnlistedAccount]

You also want the "exhaust" wind to get sucked out of the bottom side holes of the shroud for more wind speed. And you don't want the wind to blow into those holes either. So you'd want some kind of U-shape around the shroud that can turn freely like a wind vane. Or really any way to create negative air pressure at the bottom, because it will increase your air intake.

[@401ksolar]

I like it, but I had a thought-how about a Vortex swirl design on your funnel to get the air going in the swirling Direction you want it to go in the first place, so as your flaps on the tower direct the air downward the funnel would progressively spiral towards the outlet of the funnel thereby spiraling the air going to the turban, just thinking out loud(PS on the inlet facing slope of the vortex you would want smooth surface and on the trailing facing slope you would want a scruffy finish kind of like orange peels, the scruffy part is to build up air pockets to cushion and redirect the air trying to go in the wrong direction)

[@kurdaitcha3509]

All you need to do is feed the first one! That's a "Bernoulli Venturi Stack"! As air flows past each Venturi, they will ALL draw in air on all sides! Same principle as a spray gun! Actually shielding the lower portion of the stack and only directly feeding the first one would surprisingly increase efficiency! Letting the wind hit the entire stack will disrupt the effect! Airflow out the bottom will be more consistent, and directional!

[@ThinkingandTinkering]

I amnot sure mate but it think they just do that all by themselves

[@shootsteel]

Love the presentation ... most enjoyable and stimulating.

[@danedmiston9673]

Speed as a Tip Speed Ratio ( the speed on the outer tip of the blade divided by the wind speed) is very useful. Using Hertz readings instead of volts from the alternator the actual RPM can be calculated from the number of magnets in the alternator. Using the RPM and the circumference of the rotor the Tip Speed is calculated. Divide the no load Tip Speed by the wind speed to get the turbines TSR (Tip Speed Ratio). In general the higher the TSR the better the efficiency. Most wind turbines generate the most power when loaded to run at 1/2 the no load TSR.

I have a question about the top of the column of cones. Would the top of the system not be better if it was capped off with a dome or something? I'm thinking would air passing over the exposed top not create a low pressure zone inside the central part of the collectors and disrupt the downward air flow? 13:26

[@Dan-jo8py]

If you turn the entire thing upside down and make the centre piece a dark thermal mass you can create the wind you want yourself even in very low wind conditions as then it becomes a solar updraft tower (which have always been wind turbine, given the crucial factor is wind speed to their function). You can drastically increase the wind speed at relatively low cost by using a variety of regular polished metal mirrors with basic solar trackers on them to track the sun and concentrate it all onto the central thermal mass.

[@turkeytrac1]

Where I live ( central Alberta) I've seen companies testing the "electronics" of dynamic brakes on diesel locomotive by adding more electrical resistance, via a DB unit. I'm wondering if you could add a load to the generator (imput) and measure the amount that it takes slow the speed of the generator. Then using some formula where you substitute in that gathered number to calculate the torque?

[@ThinkingandTinkering]

do you know what I find mate - it doesn't matter what you do - someone, somewhere at sometime will tell you to do something different - basically you do what you like as long as you get a result that helps you

[@vsiegel]

The shroud test is quite distorted. The shroud reduces the distance between blower and air intake, it simply moves the intake up. From the test it is not clear whether it has any other effect.

[@colleenforrest7936]

Just got to thinking about those spinners that work by putting candles under them and what others have been saying in the comments... What if instead of gearing it to work on wind coming into it, you paint it black and set it out in the sun and you run it on the hot air coming out? It could probably still use regular wind and rain water too.

[@ThinkingandTinkering]

there really isn't much energy in that - it would be a whole lot of trouble and expense for very very little return is my real thought on that - but it is just what I think you could always try it and see

[@blanstevslc]

One reason I see for placing the generator section on top of the wind collector is because the wind-redirecting cones are then pointing upward (instead of downward), thus making it more difficult for rainwater to get in and drip on your goodies.

[@ThinkingandTinkering]

I don't think rain is much of an issue mate

U should be capturing the charge difference in the flow/compressing/decompressing the air by charge differential in the materials. Could be used to help charge the system to help move it

[@krissfemmpaws1029]

Looking at your wind collector cones I think vertical baffles will be needed between the cones to channel the airflow downwards otherwise the wind will just flow around the rim of the cones horizontally. Looking at it full length baffles every 90 degrees and half baffles every 30 degrees so you don't restrict the flow area. I see possible issues with reverse flow if it's not properly baffled.

some will some won't - it's really a question of if it is worth it

[@krissfemmpaws1029]

@@ThinkingandTinkering it would make a big difference those of us that have used air tools know the drop of 15% of the airflow drops the tool power by 25 to 30% easy. At low pressures and volumes it's even worse.

Many years ago there was an article in a Popular Mechanics a design from the Israelis where a wind tower has many panels around it that open with opposing wind. This put the wind into a vortex and at the bottom was the turbine where air was pulled in from the bottom low pressure side of the vortex. I think I still have the magazine.

[@ThinkingandTinkering]

[@bartronicsecurity]

Now you are doing the real stuff Rob. To help me get a better understanding of things I always like using mental pictures. And one way to do that is to equate mechanical RPM to electrical volts and mechanical torque with electical amps. You need rpm x torque for mechanical power just like you need volts x amps for electrical power. So in your setup where you have a tight mechanical -electrical coupling you have to look at the big picture. You could get high rpm which results in a high volts reading but the high rpm with no torque will also result in no mechanical power which will result in no usable current / electrical power. If you do load the electrical output it will result in the mechanical section slowing down possibly to a near stop if heavily loaded on the elctrical side. So what I do in my developments is have a grossly over sized electrical generator (maybe 5 times the mechanical side in power potential) which could stop the mechanical side if the heavily loaded. I then set the wind / fan up at a given wind speed and do a series volt to amps graph readings with a varying resistive load on the electrical side. In this way I get the MPP of the mechanical wind side. Then I do a change to the wind / mechanical side and retest the MPP and see if the power has improved for the same wind speed. Once I am reading a good bit of power on the electrical side I know the mechanical side is good and now start working on the electrical side. I do changes in the generator side to see if I can get more electrical power (using graphs and MPP) after each change with a given set uo of wind speed and mechnical setup. Takes a long time but you get to learn a lot with each change / addition.

[@ThinkingandTinkering]

[@SJR_Media_Group]

*_I have been watching the evolution of a amazing wind turbine..._* I would love to make 10 or more. I would put on side and face opening towards the wind. A simple tail fin would point it right direction. A series of cross arms would be covered with these turbines. If you had an array of 5 x 5 = 25 turbines in a compact form factor. Several 1 x 6 boards holding turbines. Air has smooth entry, and would exit in back of turbine. Someone could use sheet pf plywood. Cutout 25 holes to house the 25 turbines. That should make some decent volts and amps. A sheet of aluminum would also work well. *_Love the videos... great job .... Cheers... Mate._*

[@goiterlanternbase]

8:16 Imho that is not the main reason. This cover provides a more directed airflow over the blades. Without, air does not only comes from the inside, but from the outside and the top and any other direction, hitting the blades. Btw, i would turn the blade angle. It,s better when the wind comes from the side and goes out of the funnel. You know, like the termites and moles do it. It also reduces complexity on the part. All you need then, is a toppled funnel, the longer, the better.

Cheers Robert and Happy Easter! I would love to get my hands on a horizontal or vertical version of one or two of these! We live in the NE USA and I am not convinced feeding solar to the electric supplier will not destroy our 30 year old wood and asphalt roof. We are on high windy rural hill with no running water or ponds nearby for generation. This just looks wonderful and even at the output you are working at still makes so much sense. A small bank or to would be easy deal with in the back or side yard and should be more manageable weather wise than the wind wall. I noted in the comments that magnetic bearing or perhaps the latest liquid bearing might keep it on the quiet side and allow for less/easier maintenance. Wondering if any one locally in our area is working on this? Thanks Again and Kind Regards

[@Acheiropoietos]

I have recently been quoted for solar panels, and was advised that there should be at least 400mm / 15” clear from the edge of the roof to avoid wind damage. If you have a solid wooden truss roof, you should be good to go. Solar adds value to your home and will help keep your electric bills down, forever.

I had a friend, now passed, that was looking into making a large-scale version of what you are calling the Water's Generator. I'm pretty sure he got the idea from a book printed in 1976 called Radical Technology. Anyway, I remember telling him that golf balls are shaped the way they are, with all the tiny divots on their surface, in order to let air slip over them more easily. I.E. there is some effect caused by those little divots that reduces drag on the ball. Isuggested he try incorperating the use of those divots on the cone section to allow tbe wind to be traveling faster when the wind meets with the blades. I'm no engineer but thought I may as well tell you the same thing incase there might be something in it. Thanks for all the great videos.

[@4STEVEJOY34]

You had me with "Breaking Wind".

[@stephen2203]

Here's the advantage of the orientation of the thing on Skegness Pier (which I am going to see this year, sometime). The airflow over the top provides a suction to improve or increase the air pressure across the turbine. So you might expect that orientation to perform better than one with the airflow-exit at the bottom.

[@efinderr3256]

Been following for a while and love this channel, always gets me 🤔

[@TheStupidcomment]

Just a random thought about the wind catcher. If it had a square intake and had a weather vane style tail/flag that keeps it facing the wind then it could be more efficient.

[@edwardcolbert922]

So awesome, on the edge of my seat for 1890s

[@gacattack1234]

If air is blowing into the inlet it will be blowing into the outlet as well going against the flow of the air coming in through the inlet therefore reducing the output. Instead of having outlet holes on the side where wind can flow in you could put them at the bottom under the turbine and the air can flow through the turbine down the side, cooling the generator, and exit underneath were there is less chance of wind blowing against the flow

[@magic.marmot]

Part of the transfer is the impedance matching. The larger input has a lower impedance to air pressure, and translates to a higher impedance to increase the force transfer to the mechanical turbine itself. It's pretty much the opposite of a horn driver in audio systems. There is always an entropy loss in impedance matching, but considering the purpose, it's an excellent design.

nice cheers mate

I've been thinking about the exhaust area (in terms of Bernoulli's Principal). You might be able to get the wind sucking your exhaust, not just funneled through. A second Darwin on the bottom maybe? Or several pointed down off ports?

[@ThinkingandTinkering]

interesting cheers mate

[@AndreasDewatmoko1]

Please try the torque measument by various moisture concentration blowing with the wind (not a hair dryer).

[@johnzx14rk94]

Great job Robert. Nice work. You might want to look into the blade pitch. G.E.'s LM-6000 Aeroderivative Gas Turbines have some of the most advanced blade designs. Really enjoy what your doing, and your Fantastic Attitude & Healthy Spirit. Keep your push on Good Sir.

[@trevorlangham4057]

How about spiralling down the ‘capture’ keeping the parabolic profile of the ‘thread’ to collect more wind from any direction? Seems to me that some wind can pass through the flat-plane plates so if that can be avoided whilst putting a spin on the gas flow, with fewer eddies than putting radial baffle plates on. More wind in?

[@johnryan8645]

Love the design! The serviceable parts low down. Add more and more catchers above mor power. In light wind startup you could move the coils away to create less resistance at start, and bring them closer for higher resistance…

Print one cone then vaccume form the rest over than one

[@ThinkingandTinkering]

nice one

[@keithpatrick4173]

Back in the day we did a project at an aerospace company spending thousands to make a vacuum forming mould to make a mathematically perfect collecting cone as in intake to a small wind tunnel. A few days later walking down the street I passed a pet shop selling large aluminium dog bowls for £3 that were the exact same shape as the bowl that came back from our forming shop ready for finishing.

[@BenjaminBjornsen]

this happens in all industries, and it sucks when you find that the plastic toy you just bought for 2 bucks for your son contain the part you have spent hours and dollars designing and perfecting

[@paulmurgatroyd6372]

I think the people at Skegness put the fan high up to stop little fingers getting near it. Their funnel design seems to leave some room for air to escape sideways, I wonder if they chose this for a reason, as it doesn't looks as efficient as the original Darwin or the parabolic cones versions. Maybe they know something I don't, which isn't asking much.

[@ThinkingandTinkering]

it's just cost benefit mate

[@George.Coleman]

Turning recycled plastic into wind turbines is a great idea

[@Ricks-way.]

I've just been looking through some of your older video's, I'm looking at possibly adding some wind generation to a solar install in an off grid application (allotment shed) more to gain some power during the night perhaps when the solar stops. I was wondering about combining the likes of the Darwin collector and focusing it onto the Archimedes screw with that attached to say a 100w/12v or 24v commercial generator. Being at an allotment I want it bird friendly and discrete/stealthy. Not sure it would have the power on that smallish scale though. Great video's!

[@partciudgam8478]

Great videos! With this tech, you can fit a 1 in hole on a 1/2 inch bar. This towers could be done with non high performance materials (steel, or fiberglass instead of carbon fiber) and get the enhanced performance with a smaller turbine, on the ground, instead of having a generator gondola high above, behind the expensive turbines. Just a sugestion for your larger builds, try 3D printing a mold, and then fiberglass parts, say 1/6 of the cone, to be bolted together, the post processing of this sectors should be minimal

[@mikaelfransson3658]

Happy Easter Rob. Love your new Easter egg!🥸/Mikael PS. Now I can explane "Y" over the Darwin a half Cocktail-glass for increase the Wind! DS.

[@ThinkingandTinkering]

nice lol and happy easter to you too mate - cheers

[@earthlingthings]

I commented before but it's clear the outer sleeve is missing an opportunity to capture the side wind hitting it and could have slats much like your 1kw turbine you built. And the Darwin above doubling the wind collection. Just my thoughts. I'll be building that in the coming weeks using slightly different materials as I don't have a 3d printer!

[@robgodman1949]

I really enjoy Your videos glad that I found them. I think You are missing out on a couple of efficiencies, first having a venturi effect coming into the turbine and secondly having a venturi effect that essentially pull air out of the turbine.

[@jonathanrobinson73]

You don't have to justify yourself. Love everything you do. Thank you Robert

[@ThinkingandTinkering]

cheers mate

[@geoffreylohff3876]

Rob... I'm hoping that you will consider adding a 2nd "capture" section that is designed to draw the air out... place that on the backside of your turbine to "pull" the air & distribute it back up in the Windstream (at altitude). Should add to your generation & eliminate the wind dump at ground level. Just tossing in my 2 cents (pence?) for additional improvements. Keep up your awesome work with the channel!

[@ThinkingandTinkering]

nice one mate and cheers

[@CragScrambler]

Love your videos, very interesting and thought provoking.

[@jasonmorello1374]

One thing I am seeing, tho you may be already on to it, you need some kind of diverter shroud for the outlets, so they do not fight the incoming side wind. Personally, I think the best option might be a thing like a single piece of your top diverter, but upside down, maybe with a bit of movement, so that when wind blows against eh side, it pushes this shroud down more than it can enter, either to just divert force or to block that entirely. Say that is has a direct gap of only a centimeter off the base plate you have, which will let air flow out to meet with the out side currents, but being narrow vertically, very little force gets thru that baffling to the turbine in what would be a backward flow.

[@jonseddon4547]

Love this explanation of your development process - the modular build makes perfect sense! It's a good job you made the Waters turbine

[@ThinkingandTinkering]

lol - yes they are large

[@Homesteading101]

A thought about the unit pointing up or down. To me when the motor is on the bottom and thrust is pushing down it would put more load on the thrust bearing causing drag. Air pushing up "could" cause lift and perhaps if the generator section is not too light, then the trust upward should cause it to float and reduce drag.

[@ThinkingandTinkering]

I don't think so as the wind is always be 'thrusting' against a turbine to make it turn isn't it? and if it was lifting then wouldn't you have to have a reverse thrust bearing at the back of the shaft to stop it pulling out of the stator?

[@daveparf]

I’ve been working with the serpentine coil for about 10 years now on and off, I use it for generators and even brushless motors if I spread 3 coils out evenly, 16 turns of .8mm wire usually gives problem free starting but with plenty of power, it only works if you join two starts and one end of the coil or Vice versa then use the remaining legs to connect to an ESC, my favourite is an 8 pole rotor and 3 x 8 pole coils which gives you 3 coil poles to each magnet, try it! you’ll be amazed how well it works for an iron free motor.

[@ThinkingandTinkering]

cheers mate nice share
