 So we're just integrating the pipe into this little pool that we've got here, and as long as that can come up above the high form of the pipe, the system should self-start. One of the good things about this design is it doesn't need like proper earthworks, like we won't need to pour any concrete or anything. Basically, for Scotland, we've not had much rain, so the water level is quite low. If we can assimilate, get it all stirred up, get the turbine plugged in, run it through, make sure that it works in principle, and then come back up some rain, which we'll hopefully have in the next couple of days, and run it properly. I'll try that, see what happens. Still going. Yeah, it's not a full siphon though. It needs to be like the whole tube is gushing. We've still got air in there. We feel it blowing out. Yeah, it's running. There's no air in that at all. It can rest in a rock. Yeah. Yeah, that's good. It's got the weight. Yeah, it's good to shift it off to the side for flood levels, because when it is high, this just washes straight over. So any kind of kit sitting there would be at risk. It's quite nice to have this bit of land here where we'll set up the test load. It's quite neat, this location. No, it's good. I think that's a good run. Just test the intake a bit, and then get everything fixed up and secure. Yeah, get a filter in place. And plenty of water. We can then test it and that'll be good. Yeah, and then the water flow should keep most of the leaves off. I mean, ideally, we'll see. And then, yeah, there's not much bubble in the water by the time it gets there. Lots of stuff should move faster. I think we're able to shot. Great. Full power. Okay, let's chuck it back out, turn the water off, and then put the turbine assembly on. I think we're good to go with that now. I think. It's going to go every... Well, yeah. All right, since it's got the plexi on it, the back and sides should hopefully kind of sort of self-clean with the water flow going past them. Here's my hope anyway. There's so much surface area that, like, it doesn't need to be that clean, really, to have enough intake. Yeah, this is a much better spot. Like, the water's just so much... Yeah, it's always going to be carbon. And an extra meter ahead or one hour, however much should be good as well. That'll do it. Ah, yeah, well, we can just lift this out. That's a five-minute from now problem. Let's go check the flow. Yeah, that's proper. Now, like, there's no problems with, like, hatching the rocket and getting the sites and going or not. Like, that's completely tough, and no air as well. So I'm going to swap out that runner. So I made up two more runners. And discovered, like, these angle grinder cases are, like, the perfect small transpo caddy. So this one's more blade steeper pitch. I feel like that's going to be less efficient, but I'll give it a go. This one is basically identical to the one that's been in there just without the plastic ring around it. Hopefully there shouldn't be too much weight off it, like, if the water's in 3-4. Oh, shit. You're right. Yeah, that was me last time. Are you okay? Yeah, yeah, yeah. It's a warm day. How's the water? It's okay, mate. It's all warm. You've got to change clothes, like, near by. I'm not part of it. I'll, like, give you a shake here. Yeah, it was an interesting train ride. It was, like, that train was up to the waist. Are you going to wire it up first? Um, let's just get it going like in the circuit and see what happens. Okay, good luck. But then, yeah, after that, I'll put a load on it. All right, Tucker in. No, it's moving. Well, that, unfortunately, answers that question. No, these are not strong enough, as is. Okay, so take two with the steeper pitched nine-bladed fan, which is probably weaker than the other one, if anything. I think, well, hopefully, the previous one was just snapped, was, like, just a shitty fan, basically. But I have no guarantee this one isn't as well. I'm just going to tuck it in and see what happens. So, the highest reading. Seams it. But the steeper pitched fan will bolt lower. Or speed higher torque. It might have just been lower, efficiently. So the second propeller also exploded, but weirdly not until the last second when we turned off the water. It was spinning about 60 volts up until then. That was probably five. It might have lost some blades, or there might have been some friction in the system. And then as soon as we killed the water into the path, like, all the blades are gone. So it's almost like turning the water off is what sheared them. So I'm going to now chuck on what we had originally, which is the ring-reinforced blade. It's going to be a lot stronger. But the problem last time was that a little stone, a couple of little stones just got sucked in. And basically, this is supposed to be flat. That's all been ground in by the stones grabbing in on there. So I'm going to take out this innermost ring of plastic gear. Hopefully I'll give it enough clearance to that with the finer mesh screen up the top. Hopefully mean that it can happen again. And this should be a lot stronger and hopefully hold up. So I'm going to put this in place. I'm going to do another power test. And then I'm going to leave this running for some days and weeks to see what happens. And then reassess, basically. And I think I'm going to get a Seriva fan with the same shape and not a lot more expensive, but a lot stronger. It's like fiber reinforced. Hopefully that will hold up. And I'll just get some better standard fans which are a bit stronger plastic. I think the ones I got were a bit too cheap. And it just couldn't take the load. But hopefully a less cheap, less cheap one will do it. OK. Let's chuck her in and see what happens. What's that? 50 volts, 2.5 amps. So it's 125 watts right there. That's not bad for like 10 or 5. That's 50% of your open circuit voltage. And that's generally where the maximum power point sits. 121. I'm not unhappy with that. That is for room conversion. So 125 watts is not bad as a starting point. It's less than the 200 I was getting in Berlin with a few reasons for that. Mainly that in Berlin I had 125 millimeter pipe before the turbine and 200 after. Here it's only 110 and then 160. Also the hoverboard wheel that I'm using as an alternator here turns out to be only putting out about 42 to 45 volts DC rectified per thousand RPM as opposed to the Berlin one which is doing the more standard of about 55. And the liquid rear stat I was using wasn't quite conductive enough to pull the maximum amperage to max out the power curve. So we're still cresting that curve with that measurement. And so the next day I go back, I will tweak that and the other optimizations I've got in mind including a vectorizer for angling the flow onto the turbine so it vortexes and spins the water onto the blades rather than just having it go through straight. I don't know what that's going to do. Maybe it'll make it better, maybe it'll make it worse. I'll find out. But so the next video will be that last 5, 10% efficiency and power extraction as getting the system sort of honed in on its sweet spot. I'm a little surprised that the fans blew up like they did. I have used them before and they've held together quite well. I think it was maybe just because previously I've had them on turbines that have about two and a half to three meters of head. This one has about like four and a half. So notice the extra pressure just sort of crosses the threshold of what they can survive. I will experiment with ways of making them stronger and I've also ordered a server fan which is basically the same thing. It doesn't even cost that much more but it's just a lot stronger plastic basically. So I'll be trialing those the next time I go out to Glasgow as well. A few of you have been asking about the tutorial when that's coming out which is good. There's that much interest in it. The answer is soon basically. Currently I'm updating the wind turbine tutorial based on the data that I'm getting off the rooftop installation here in Edinburgh. And as soon as that's done basically I'll launch straight into the 3D animated step-by-step tutorial for this. That will be on the channel and on the opensourcelotech.org website. And I'll do another video coming out soon on the wind turbine and then the water turbine. And so that's basically it. So I hope you enjoyed the video. If you have any questions comment them here and I'll get back to you. Also you can email me directly through the opensourcelotech.org website. My email address is there. And like, subscribe. The usual stuff. You know what's up. And I'll see you in the next one.
