@@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.

[@LostSockDrawer]

I am absolutely astounded by a youtube video for the first time in a good while

[@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.

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

[@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]

Your system would have to be tougher than a brick! Good luck. Whatever you devised would certainly be quite durable everywhere else! Sounds challenging.

[@ThinkingandTinkering]

from what you say just about anything would do mate

[@robertwagner2079]

I have seen horizontal spiral turbines at 6" dia. that looked very impressive. I can't remember the numbers now but there was low coefficient ratio between the turbine and the mounts.

[@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.

[@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.

[@ThinkingandTinkering]

yes it is - I thought that too!

[@4STEVEJOY34]

You had me with "Breaking Wind".

[@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.

[@ThinkingandTinkering]

[@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

[@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!

[@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.

[@ThinkingandTinkering]

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

[@shootsteel]

Love the presentation ... most enjoyable and stimulating.

[@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.

[@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.

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.

[@yaka2490]

thanks robert yeah not sure why the need for the big bin shroud mate imo you should focus the air from top collector to have as much velocity as possible and thats done by converting the caputred air and converging it as much as possible imo. more Vel of air faster rpm...

Great design Rob. 11:54 It even puts itself together :)

[@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.

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.

[@ThinkingandTinkering]

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.

[@huguesmassin8903]

Hi SIr, you could mesurate the output of air from your device by tying a 30L bag for example to the end of the device. Another point, with a so low resistance whell, we could make hot/cold air system around with a funnel of hot air for example coming from the top to cool down inside a tube flowing on the wheel, to make passive thermo-wind turbine. with cooked clay tube with the base sitting on a water bed. Thanks for sharing all this.

[@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

[@rickgividen4318]

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.

[@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.

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.

[@johnbarry8185]

Robert, create a plexiglass cylinder to go anterior to the Water's turbine. Then place a constant flow of air into the cylinder. Use either smoke or colored air, to see where the air flow is NOT moving through the turbine. From there, you can improve the turbine. It is my belief, that there will be quite a bit of turbulence at the top of the turbine, that is escaping WITHOUT moving through the fins of the squirrel cage. This will be the inefficiency of the turbine. You would probably do better, to make the squirrel cage the same shape as the cone, only slightly larger, to allow for the air to travel in, and have no way out, except through the fins. Keep up the good work.

*_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._*

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.

a suggestion on the wind capture is to add a screw-type internal parts to create a vortex supply in accordance with the rotation of the actual turbine.

As I did enjoyed the series about the first 1kW wind turbine, I do enjoy this one as well. So, Thank You! :)

awesome - cheers mate

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.

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

I was glad to see the Hart cordless tools and Ace Hardware wheelbarrow. Hart cordless tools are actually very decent power tools for even heavy use, especially considering their price compared to other brands. And Ace is the best “hometown” hardware chain out there.

As a fond kite flyer, anything over 20m up should give you a constant breeze. If your stack of cones are ten times bigger and higher, it should work great in the slightest of wind. Well done Rob. Great design 👍😎⚡⚡⚡⚡⚡

[@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.

[@CragScrambler]

Love your videos, very interesting and thought provoking.

[@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

[@kurdaitcha3509]

Bernoulli effect!!! It never occurred to me until I saw your "wind collector"..... That's a Bernoulli Venturi stack!! As one Venturi draws past the following one, it will cause that Venturi to draw in air as well. You only have to feed the first one a tiny bit of air the cause the others to draw in! Airflow will be much more consistent! Increase the Venturi stack and add a sail on the first one! If any of them get air they will ALL draw, from ALL sides!! Damn mate! Clever bugger ain't ya! That is genius!

[@ThinkingandTinkering]

yes it is!

[@dustinmorrison6315]

Keep up the good work! Consider testing multiple input wind speeds if you haven't already.

[@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!

[@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…

[@brianclewer1600]

Great video.. I have an idea I would like to see you do about making the turbine more efficient. On the stationary cone piece, you could try to put some vanes just before the moving turbine vanes. If you can start to spin the air on the stationary cone so that it exits the cone perpendicular to the moving vanes, I think you may get more thrust. Maybe that wasn't well explained but not sure how else to put it..

[@ianbottom7396]

“Ground Breaking Wind” it wasn’t the video I was expecting Rob 😂

[@scottflower6547]

I would think that the reason they are putting the structure upside down is because of rain. I think you might want to look into this because it might cause a short. Great job!

[@ThinkingandTinkering]

it won't mate - rain isn't the problem folks seem to think it is
