Those vertical supports can be modified to become "stators"- static reverse blades which guide and direct the wind onto the rotors. At the moment the orientations fight each other and probably create a lot of turbulence.

This turbine is more efficient in the vertical mode as the wind can come from any direction. In the horizontal position the turbine will only receive wind in two fixed directions.

Loving the series and it's good to see theory put into practice. I'm confused on the purpose of the baffles or why the blades are straight and not twisted like a propeller. I'm certain there will be good explanations for both and would like to hear from other people on this.

@snuffoutrouge5109

Жыл бұрын

I think the baffles direct the wind into the turbine. The blades are not twisted like a propeller as this is a low torque design. A propeller is designed to attach to a central small wheel plate but create high torque. Also there would be no more than four propellers. and balancing is more and an issue.

Rob, someone may have already suggested this but it looks ideally designed to fix onto a car roof-rack for testing? Then you might be able to use a still air day, drive at known steady speeds and produce repeatable results. You can't do that with a big bladed turbine! And the protruding threaded bars are perfect tie-downs. If the police stop you just say you are taking a tie fighter to the film studio!

Awesome Sir Robert! That's a beautiful piece you have built. As others have mentioned the unbalanced rotation may need a quick fix but I think you have built something with lots of potential for increases in flexibility. You can add to, or change this or that. Lots of versatility. Well done sir!

When you mount this on a flat roof, try extending the baffle plates to the four corners of the roof; ie several feet long. That would substantially increase the volume of air ducted into the wind turbine. That might be worthwhile for most of England where wind speed is usually low. 😀

@paintedwings74

Жыл бұрын

Good idea, and those baffles could have covers that are open under most conditions, but excess winds would cause them to snap shut. A safeguard against storms.

Learnt from Enviro Physics class that power is WindSpeed^3 (cubed), so the max wind speed is very important for selecting a site.

Bifilar coils can be tuned to prevent cogging. The tuning will be easier to figure out once you know the resistance and inductance, then pick the right size variable capacitor to tune it. The back emf can be used as a boost instead of causing the cogging action

looking forward to the 5th (and probably final) in the series. :) this has been one of my fave projects of yours.

Hi Rob. Pretty impressive. And the build standard looks really good. One thing, though :- the baffle plates are normally oriented so as to direct the airstream into the rotor on the downwind (drive) side and away from the rotor on the upwind (drag) side so as to minimise the adverse drag. The way you have them oriented on the upwind side will actually increase the adverse drag. I hope you don't think I'm nitpicking, I'm just trying to be helpful. I'm sure it;s going to work well.

I built something like this on a smaller scale about twenty years ago. I'll be interested to see your approach with the stator. Lots of home-brew wind turbine info suggests winding multiple coils and overlaying them. I found this messy and complicated. I finished up laying two rows of pins around the perimeter which were spaced at the same pitch as the magnets and then ran a continuous conductor out towards the edge and then back towards the middle on the next pair of pins and continued around the stator several times. I stuck it all down with epoxy and then removed the pins. (This would be a lot easier to explain with a diagram) That provided one phase and worked really well. It might be more challenging to attempt this with the gauge of wire that you'll be using. I did begin a three phase version where I had the same configuration repeated three times at 1/3 the pitch of the magnets, but then I got a proper job and the project ran out of steam. I've still got a few bits laying around.

Hey Rob I wanna say thanks for giving me the confidence too start making my own wind turbine I have short videos of the fan I'm gonna I'm turning a 2hp electric motor that was with it into a generator wish me luck

Yes but, then the cogging from the magnets would increase. So, yes more power output but, it would require much higher starting wind speed and due to that limiting factor, would not be as efficient. Also would be useless in winds under 15 MPH. If you consider that the lost power generation with lighter winds could have at least made 100 to 150 watts an hour on a low wind day, then it is obvious that the need for higher wind speeds is a big set back to the goal. Instead, either make the base wider/ turbine taller ( more surface area ) or install multiple given how cheap they can be made so that you get power out of them in low winds as well.

I would place magents at top AND bottom. Use place even black and white strips along the edge of the drum. Use these strips to sense the rotational speed if the drum so it spins in small winds and by raspberry pi, pit the coils in and out of circuit to adjust the load based upon wind speed. Otherwise there maybe too much dynamic load in the drum and slow it down.

Nice, the issue I see you running into is the pressure envelope that will limit the RPM regardless of wind speed with a VAWT, obviously the reason the a HORIZONTAL axis is used is the ability to overspeed. That is why one does not see VAWT in large commercial use often. I personally love the VAWT due to the self stabilization at high speeds. The blowing up thing is not ideal with over speed of HAWT. You will get around 200 watts hopefully ( at full potential and optimal wind, AKA not 1KW ). We shall see. Also, one could simply attach a belt or chain to the outer rim where you placed the magnets, then to a motor and voila, you have an interchangeable gen-set with simple maintenance. Of course, you would also need to strengthen the turbine axle. Anyway, cheers.

You double the output by placing another set of transformers and magnets on the top disc as well as on the bottom.

I am really really enjoying this series Robert! It is vintage Dread Mad Scientist Robert. And I can’t help commenting after your insights at about 2:30 in. Like most of my comments this is a little far a field. If you read on, consider yourself warned. Similar to how the wind generator’s marketeer’s “theoretical” will vary greatly with the user’s “reality” the same happens between the marketeers promises and users experience of tankless “on-demand” hot water heaters. A new Rinnai claims to produce 10 gallons-a-minute (38 liters). But here are the conditions: 1. The incoming water temperature must be 57 degrees F (14 C). This occurs in the United States at about the latitude at the top of Tennessee (and likely nowhere in Great Britain). (That’s the average, so a few degrees warmer in the summer and several degrees colder in winter.) 2. More important though is the temperature difference between incoming and outlet at the faucet or shower or dishwasher. If you have 57 degree F incoming water and you want 115 (46 C) degree water at your shower (absolute minimum I would say) in the morning, your flow rate is now at 6 gallons a minute (22 l). That’s not awful because the average shower head in the United States uses a bit more than 2 gallons a minute (7.5-ish l). In Seattle, Washington, where I live, in January the incoming city water supply is around 45-50 degrees F (7.2-10 F) and my minimum temperature for a shower is 120 F (49 C). Now the flow rate is 5 gallons a minute. 3. Those numbers are for a top of the line, state of the art Rinnai RU199in, $1666 on Amazon and you will pay that much at least for installation. 4. Finally, unless your natural gas line and meter was installed with a tankless water heater in mind you will likely need a bigger line from the city main and a bigger meter. The sales person won’t inform the buyer of the real world numbers. The salesperson likely only knows the ideal theoretical numbers. And for sure NO ONE at Amazon will know any of them. This is why, you see so many disgruntled angry reviews for tankless hot water heaters EVERYWHERE. The customer over expected the flow rate. The customer under estimated the temperature differential (or more likely didn’t even know). The tankless unit itself is under fueled so the flame drops out then restarts then drops out. And what do you suppose is happening at the shower? This is not meant as a rant. My tankless runs flawlessly, producing 135 degree water in the winter sufficient to have a shower, the dishwasher and the washing machine all going at the same time. My point is, whatever the wind generator salesperson promises, divide by two (to allow for the marketeers lies, misinformation, and ignorance), then reduce your expectations by 10% (to be safe 20% is better). Then look for the wind generator that will serve your needs. Or better yet, follow along with The Dread Mad Scientist Robert and make your own suited to your needs. Thank you again Robert for sharing your joy and your brain. Your YTs always delight and never fail to inspire.

I would love to see these beside the highway. Anyone who's ever tried to change a tire on a busy interstate can attest to the strength of the wind, especially from big trucks.

Great job Sir! A bit of thinking- in the horizontal position of the assembly you get dry magnets,no moisture accumulation.

@Desmond Bagley quite possibly yes but the area that is swept could be calculated by re arranging the formula to make area the subject, once an average energy output is measured. This would then give you the information you need to calculate power at different wind speeds for this particular device. My gut feeling is that the area of the disc will give a fairly good estimate of power available. Its also worth baring in mind that this is simply a mathematical model for calculating available energy and therfore will not give an exact measurement of power output as we are making assumptions about the conditions, for example the density of the air, neither does it allow for the efficency of the turbine. What this does is give a good idea of what to expect from the turbine. Only further testing would give an more accurate picture of what it truly is capable of.

Oh, I eagerly await your next part on this project, and thought this would be the one where we see it spinning nicely on your roof. Oh well just a bit more patience, I’ve watched all your renewable energy projects and think this is by far the best!.

awesome mate - thank you - I am being a bit detailed with this one as I think quite a few folks will want to build something of their own

@@ThinkingandTinkering you've already got me thinking about what I could do with the bicycle wheels left over from my recumbent trike build. 😁

great project so far! Good construction as well.

cheers mate

Very nice, looking very good indeed. I'd be very tempted to mount a centrifugal braking system of some sort on it (going with the recycled everything approach, maybe a centrifugal clutch mechanism from a chainsaw or similar). If you get hit with a storm, even with more static balancing to remove the obvious heavy spot (created when magnet potting, I would guess) vibration caused by dynamic imbalance is liable to tear it apart, you're really going to want to slow it down before that happens.

yep - exactly what happened mate and I am pondering a braking mechanism - I did hear VAWTs we self limiting to a degree so I am equally interested in seeing if it would hole together in a storm - after all if it does then construction would be super simple - I might well do that just to test it

That is better than my idea to make a wind generator that uses a vertical wind turbine that has some spring arms to slap some piezo elements to make electricity.
