1889 Ground Breaking Wind Turbine Update

foreign hi everybody so if you're a regular follower of the channel you know that we're working on the Darwin wind turbine the Darwin wind turbine is kind of funnels to direct the wind down but it's a large project so take a while and the thing is I'm 3D printing quite a lot of it and I can't decide half the time whether the 3D print it or hand build it but so far I've been 3D printing it and some of these prints are days long so we get on with other things while we're doing that and of course investigate other effects that we're having to notice as we're building the Darwin wind turbine and that's left to things like the the new Tesla turbine that we're looking at we looked at rainwater turbines all kinds of stuff and that's kind of done in between the main project so I'm going to give you a bit of an update what we're doing and where we are and how long roughly it'll take me to finish it well that's about as long as a piece of string we started this project with this thing here what this is is a Waters turbine now there's lots of information about the performance of water's turbines but they're very interesting things and we started this water's turbine with the Roadster attached to the turbine because we're interested in speed at The Rim as being the possibility of generation so we've got the orders turbine and then connected to the water's turbine is this generator which is here and in there we've got a serpentine coil now when it comes to looking at the performance of these things you're basically looking at three different elements of it the first one is the generator and how well that will perform the next one is the wind capture of this beard here the turbine itself and how well that'll perform and then remember the Darwin which is basically like that which is a load of parabolic cones funnels goes above it the wind comes in this direction and gets directed down there that's a wind capture device so we've got a wind capture we've got a wind turbine and we've got a generator all into this machine and of course what we want to do is you want to know always is any of the stuff we're doing making any better or are we just wasting our time so because we need to measure that to get an idea of how much better it's going to be if we measure just the power out well that's actually not telling us very much now I can understand that you know Folks by a turbo has got blades on it's got a generator it's all attached the wind blows and out comes the energy and you think that's the measure of it well it isn't really because of course we have three parts if we measure what comes out it's telling us about the whole machine but nothing about what might be wrong we actually need to measure each bit so that we can get an idea of what it is that's actually performing well and keep that bit and what it is that might be performing badly and throw that bit away we don't really want to throw the baby out with the bath water we want to keep the good bits now I've got a reasonable amount of fat in this water's turban design because it's been well ex well explored it's been well tested but how would you measure how well your wind capture device is doing I mean in this case it's the waters but of course we can use propellers in the Tesla we're using cones or plates but there's ways of telling how well just this bit is doing because the question is what does this bit do well this bit of course catches the wind and turns it into a rotational force and that's what we want we want rotation from the wind blowing on it and of course to measure that rotation is to measure the torque so we can measure the torque on the shaft that comes in or goes out of there that the wind is blowing on this and making it turn that torque measurement is an indication of how well this thing's actually doing clearly if we generate more torque that's better than if we generate less torque well we need to rethink what it is so the talk is what we want to measure when it comes to the wind capture device now if we take the generator separately this is bit harder to see because it's actually integrated into the device so let's say we use this as a generator and we had a propeller on there like that in order to evaluate the propeller we'd measure the torque produced from the propeller in order to evaluate the generator then we need to measure the power produced by a generator with that given talk so measuring power faults an ounce that only tells you really about the generator or about the whole combined device it doesn't tell you anything at all about how well this is doing it's telling you about the command device and you're not really getting the information you need what we need is information about torque so this thing will have I been printing well first thing is a base for adult to stand on because obviously we need to make it so that it can have a stand and make it not move or blow away or want to fix it to something etc etc so I've got this ring and if I slot my generator into that ring there we go gently obviously but it's not my generator into that ring then pop that on there we go it gives me a base the reason I've done that is because this huge thing here which took several days to print is a um part of the wind collector it's basically a funnel that funnel fits neatly into this ring here there we go and directs the wind down onto the water's turbine which then gets blown out of the sides so that bit goes on the top there to allow that to happen all right there we go just like that so that's what we've got at the moment now obviously what we need to do is put the actual structure on top which will look something like this on me bigger and that will go on top there to finish the Darwin wind turbine and it's this bit that I'm mulling over at the moment which is why we've been looking at um Tesla routers because I'm having a think about this now when I first did this there was quite a few people who said that would never work and of course who've now put something very similar on the pier at skegness and there's a company producing this the company is actually making everything go upwards we're making everything go downwards and we're more interested in it being downwards because it puts all the um electrics all the mechanism you might want to look at at ground level or eye level somewhere you can work on it without having to clamber up on the thing and from our tests it seems to work just fine and that's where we are with this we are got the Shroud done got the turbine done got the generator done we now don't need the wind collection structure and as I say I'm not sure if I'm going to print it or if I'm going to make it by hand out of flat panels I really haven't decided and of course the obvious question is is this doing any good okay Matt there we go okay that's good that's good it's not the most impressive but half a volt let's put the Shroud on [Music] and it jumps up to a fault one point what awesome and if we take the Shroud off there you go it slows down thank you man that's all right okay so a quick and dirty test doing it exactly what you think it would do which is kind of cool to get that information because of course the surface area here is about twice what the surface area was there and it's been focused down onto the turbines you would expect it to do better and you'd expect it to be round about twice as good because it's round about twice the area that it's covering so no surprises there on what we got showed that that was actually the case so we know we're doing okay so far now one of the reasons to measure faults is if you remember a generator is actually governed by the strength and magnetic field the length of the wire that goes through that magnetic field and the angle that that our one makes and the speed at which it turns those four things we're going to get a voltage figure out now in this particular case because we're using all the same stuff three of those things are constant only the speed can change that's the speed at which that rotates is the only difference we can make it we're giving it more push because it's more wind and that wind is focused it's going to go faster it goes faster it's going to create a greater voltage and so we're able to say that that's actually doing better we're not measuring the torque directly we're just getting an impression of the talk by an increase in the speed because there's more wind pushing on it and that's the kind of guide I've been using now obviously what I really want to do is get a proper way of measuring the torque like a strain gauge or a crony break or something where I can measure the talk directly but I don't have those things and so I'm using volts as a way of getting an estimate of is an improvement in the talk and we're only looking at this section here what's coming out of it makes no difference to us at this stage we want to see an increase in voltage what that voltage is really doesn't matter we just want to see whether it increases or not when we make changes to this bit which is the wind converter bit this bit converts wind energy into rotational energy and when we're working on this that's what we're interested in so just to drive this home because it does seem to create some confusion when we're measuring volts we're not measuring generator output we're using the volts measure as a way of measuring the speed of the rotor if we measure the speed of the rotor then remember power divided by speed or RPM is torque so we can use it as a guide but we are using volts to measure the speed courtesy of blv sine Theta we are not measuring the generator output because at this stage we don't care what the generator output is because we can always bolt a normal generator to it we're only interested in what the rotor is doing when we're designing rotors oh I ought to mention this meter readings I've been trying to give you a view of the meter but to be honest most of the time it doesn't even matter because I'm not trying to prove anything to you most of this stuff is actually uh well researched and well documented you can have a read and get the proof that way if you want in fact the only really different thing in this is the serpentine coil so the meter reading barely matters most of the time I'm just explaining what I'm up to as opposed to trying to prove something you're trying to prove something then sure I'd be a bit more diligent but I'm not I'm just explaining what it is what it is this big [Applause] wind collection system so again when looking at this if we add this and we get more push on this because we've added that that's what we're interested in what comes out of the generator an absolute figure at this stage do not care when it comes to measuring what the generator is doing fantastic if it turns out in this generator that we've got here is rubbish none of this has gone to waste we can just buy a commercial generator and stick it in there instead of making our generator we would then know still that this is improving this is improving this is improving remember we made a mistake with the generator we have to replace one mid it doesn't matter what volts and amps come out when we're looking at how well is the wind collection system doing how well is the wind conversion part doing that's what I've been looking at when I've been building this you can see I've done a large part of the wind collection system which is that bit there then that is the big machine that's been sitting on the back because several people have been asking about that bit is a test bit we're going to use that for our Tesla turbine but it's actually a test bit to see how that section of the wind collection system will do and of course these are being actually done now I can't remember who the company name is but they're making these in sticking them all over the UK I hope you enjoyed the video I hope you enjoyed the update I hope to explain a few things about what it is that I'm doing and why I do them thank you very much for watching and please do remember to
