Awesome Low Head High Flow Grid Tie Micro Hydro 530 watts!

I travel to a summer home in the mountains of Western North Carolina to meet Bill. He has come up with a way to pull a lot of water over a dam and into a permanent magnet alternator. He feeds the power to the house to supplement what is used. Bill is using Langston Alternative Power for his setup and makes around 500 watts.
www.langstonsal...
The interesting thing about this micro hydro setup is the way that the system is started. There is a lot of water that needs to flow over a dam. To get this system going Bill uses a simple shop vac to pull the water over into the 6" pipe.
No batteries or charge controller is needed. Simply a grid tie limiter inverter.

[@JCJC650]

Could have a float sensor that detects the lake level and controls a 6" valve near the intake. That would prevent the level of the lake dropping too much and loosing the siphon.

[@JCJC650]

Actually it's probably easier to regulate it with a device on the priming side. You could T off to an automated valve to allow air in and on the other side of the t an automated shut off valve connected to suction (also automated). You could control it with some relays and a pii / arduino. When the float detects the level lowering it would start to let some air in, more and more as the level drops untill the system stops, then when the level returns to the max the air valve would close and the valve to suction and suction would activate for a set amount of time before shutting off to restart the system. That was there are no valves reducing peak efficiency

[@richardschofield2201]

I'd be careful restricting the inlet. With all that vacuum it could cause cavitation which would knacker the turbine. Better to let a bit of air in downstream to partially disrupt the siphon. I would bother with an Arduino. Too temperamental and fiddly. You basically need an old toilet. Use the ballcock and valve as an air bleeder. You may need a larger valve, or use several ballcocks at different levels so the system ramps up and down. It's a tune and forget system.

It needs to have a floating needle and seat in the intake pipe to reduce the flow automatically if the water in the pond drops. That way he can avoid draining the pond and sucking air into the intake.

[@masonborden5594]

The vacuum you pull with that flow is insane. The venturi effect usually leaves a lot to be desired in denser fluids (water rather than air) but on a scale like this with a 30% increase in volume at the tailwater you are getting a massive vacuum. Its actually beautiful. You could increase the flow but that could lead to several issues in other areas, and fixing those might require some shotgun science. Patch it all and hope for the best. Guess the issue. You have a beautiful setup, sure it could be improved but why do it.

[@timhallas4275]

He doesn't need a vacuum on that pipe. He has a downhill drop of 15 feet. Once that water begins flowing, gravity alone will "pull" water from the pond. But here is the real point. He could easily have drawn his water from below the water line at the damn face. No siphon needed. Also I am certain that this flow rate could easily produce over 2,000 watts, ending his need for any power from the grid until winter.

I know that there are limitations on location and practicality, but the turbine would last longer if it was placed down the flow path (low water pressure will cause cavitation on turbine blades and increase wear & tear) but all in all great job for making something green out of household materials !

[@tommybronze3451]

@Artificial Hobos hmmm, don’t know if there are of the shelf self contained (with generator) solutions for that around. My only point was that if they are running it through submerged turbine, I would place the turbine assembly at bottom end and slightly restrict the exit nozzle (5% maybe) which would increase internal pressure and eliminate cavitation. But if the use something (like pelton wheel) which is built for air in the housing than my point is very much DOA :) but to your point pelton wheel might be more robust if stones get captured in the pipe. But going back to the placement - it better to extract energy from positive pressure which can come in many BAR than negative pressure that can only get to -1 (well 0 for vacuum but I’m referring to pressure expressed on working part).

[@tommybronze3451]

@Artificial Hobos I love the ghetto style with washing machine motor :) Old engineering paradigm: "if it works, it works". In regards of Australia - I'm not sure how anybody could build any hydro there, one it's pretty flat, second water is a bit of luxury. But if one is so lucky to have both (river and decent elevation change) go for it. Thou in Australia, I would think solar would be better solution since sun exposure is a greater and land prices cheaper, but again all depends on what's ones circumstances. Going back to turbines, alto I think Fransic would be better than Pelton, I like the idea of aerator for a small pond and having some fish as well. Mist from Pelton could also provide nice cooling effect on hot days, so three birds with one stone :)

[@tommybronze3451]

@Artificial Hobos Do you remember the name of that series ? I would watch it and maybe drop him some info on bearings if I found something obvious ?

[@DwayneShaw1]

This is brilliant. With the vacuum pressure you're creating you could probably stair-step a couple more turbines into the system - cover all your needs. Might also create enough drag to slow the drain some - so you have less worry with draining the pond. - Would a smaller pipe configuration slow the flow while still producing sufficient pressure to spin the turbine at optimum efficiency? - 3" or 4" to 6" pipe, instead of 6" to 8" ?

[@edenfromafrica4725]

Well done Bill, even just a hobby, but its great to see your technical aptitude.

[@brothertyler]

Great work, you can increase your efficiency by installing transformers by the turbine to raise your maximum open circuit voltage to near the limit of your rectifier input.

[@researcher4good]

Exactly. It's not efficient because it's AC. It can easily be made efficient because it's AC.

[@dwbogardus]

One hundred feet is a very long run with high loss for 24 Volts. Put a step-up transformer to 48 V or maybe 120 V near where the turbine now is, and move the diodes (which need to be on finned aluminum heat sinks with convective heat flow) to near the inverter. If you pick 48 Volt step up, you'll need an inverter that expects 48 Volts, and there are some. If you pick a higher voltage, there will be lower line losses, but you may need another step-down transformer just before the diode rectifiers that feed the inverter, and losses from the second transformer may negate the higher 120V (or what ever you choose). 48V probably ends up being the most efficient. You also might consider Silicon Carbide rectifier diodes, since they are more efficient than ordinary silicon diodes, but more expensive. Since you've only got about 500 Watts to work with, it is silly to give up a significant fraction to avoidable line losses and diode losses. There is a very good reason power companies use high voltages . You can also use heavier cable for your long run, but heavy copper cable is expensive, and raising the voltage is the cheaper and more efficient way to achieve the same thing.

[@holysirsalad]

@@dwbogardus If he moved the rectifier beside the generator, another benefit would be using the cable properly: +, -, and a safety ground. At such low current this setup technically works but, if I was his electrician friend, I wouldn't want anybody talking about that! (For that matter, I'd probably insist on a dedicated breaker and ditch the suicide plug) PV inverters work with higher DC inputs, an MPPT would be a decent fit for an asynchronous generator. One drawback would be cost, however: If he's pulling about 530W on 3-phase ~24V over 100', the drop over the ground wire - which is 12 AWG in a 10/2 cable - is over 20%. That's relatively quite high but at this scale it doesn't seem like much power, I'm not sure the ~100W or so would be worth the expense.

[@simeonsimeonov5205]

Brilliant ideas! I believe that there is a small voltage drop on the line that can be reduced by doubling the size of the conductors of the line. Greetings

[@Geoduct123]

Maybe put the inverter closer to the dam. 24volts 500watts is 20 amps going 100ft is about 20% voltage drop. If he switches it to 120v at the dam that 10 gauge wire offers a 0.5% voltage drop.

[@lorditsprobingtime6668]

@Dane Duttry Not knocking your suggestion at all and have never built a hydro setup at all so this is only a suggestion that may be useless for reasons I don't know of but: I was thinking after reading your suggestion of an idea. How do you think it would go if he had something like a large ball valve at the bottom to hold the water till you're ready to run it, up above but just below the dam runover he had a funnel mounted in a section of the water ran into normally over beside his pipe and it fed into it. The ball valve closed the water would soon fill up to that point just below the edge and if you had a floating ball that fairly cleanly sealed off the funnel when you opened the ball valve and things started sucking (in the best way) then you'd have only the ball valve to open to get the system running. I know it wouldn't make a huge difference but, every little bit easier it is to operate and control has got to be a help. Anyhow, like I said, I have no experience, you do so I'm just throwing an idea at someone who has experience with this sort of thing to see what you think, useful or just a dumb idea that may even cause more problems than it's worth?

[@malcolmrayner1613]

I pumped water a long way to a tank i would trap all the water in the pipe to prime the pump

[@mrgoldendeel]

Another thought, could you install another gate valve before the turbine to control the rate of intake so the suction doesn't drain the pond below the dam and ultimately the intake?

I think instead of using the shop-vac you can put a Ball Valve near to the Outlet and move your Shop-Vac Hose connection to a higher point under the turbine to use it as a filler pipe. To start the Syphon for the first time, you have to close the lower valve, open the upper one and fill the Pipe with Water until it overflows from the filler pipe. Then close the upper valve and open the lower one. At this point you can turn the Syphon off and on whenever you want, only by turning the lower valve.

[@propellerhead2000]

I think that lower valve could be fitted with an actuator controlled by a simple Arduino device which could be used to monitor pond level and throttle water flow to ensure the pond stays full to the brink of spillover. Or at least not vacuuming the pond dry.

[@TheNewFaceOfHSP]

While we are talking electrical safety, I couldn't quite make it out: Is he backfeeding his home through an electrical outlet, from the bottom of the inverter? I would hope that was the feed-in for grid assistance, but it was a bit confusing around when he says "from the grid into the grid", and then proceeds to talk about a metering clamp preventing backfeeding and killing a line worker. I really think this entire setup is extremely sketchy. I would have powered an MCB or two, with separate lines, feeding from the inverter, and then having the inverter take grid power to supplement it, when it can't do it using the generated hydro power. That could never backfeed. The inverter would have to be rated for the entire electrical group it would be supporting, but I think it would be safer. Relying on an external metering clamp for "island detection" seems weird. It looks so janky. Maybe it's just me, considering all the safety things we have to do in my country, and basically use a changeover switch for anything that could backfeed (like a generator) and being required to use not just an electrician, but an "authorized electrical installer" to come and wire in systems like solar, if we want full grid-tie.

This is impressive. I love the vortex destroyer. Actually it would have been better to rectify the generator output to dc down near the turbine. Fewer losses in dc. Also the rectified power will be at a higher voltage than the ac which will reduce losses further. But with such a short run the losses are likely to be minimal anyway. As for people commenting about dangerous use of the ground wire to carry one phase, this is nonsense. Remember it’s only 24volts. Overall it’s a clever well thought out system. Well done from uk.

[@LandtoHouse]

I have heard both sides of the argument on the DC vs AC line run. I would have to agree with you that power over only 100 feet is not going to lose much. Is it easier to run 3 phase long distance because the amps are on 3 wire and not 2?

[@milespostlethwaite1154]

Land to House I am part of a company which designs and installs Microhydro systems full time. We have done a few small systems similar to this and as for the question of whether to rectify at the turbine or the house, I would say that in this case because the distance is so short it makes no difference. I think I would have done the same as you just to give the water less things to corrode. Quite a few people install their own Microhydro systems. What I noticed about your system is that you have not made any mistakes that everybody else does. You have spent time thinking about it. For instance the position of the ball valve on the draft tube is just about right. You can have the valve open while you run the vacuum without water from the river being sucked backwards. The 8 inch pipe at the bottom to optimise the vacuum is a good thing.

Miles Postlethwaite ... only 24 volts after it's rectified. Probably 30 volts or so AC but at 500 watts (available) that's enough to blow you on your ass if your fingers are in the way, which is why you should use 3 wire (not 2 with a bare ground) on that system. The outer jacket is not rated as electrical insulation.

That’s right, this is how you get electrical power for this kind of setup. For “raw” mechanical power, formula is : Power (W) = Flow (kg/s) x height (m) x 9.8 (gravity, in m/s/s) 1kg of water is precisely 1L (at 4 degrees centigrade / ~39F) So for 1gpm @ 1ft head: ~3.8/60 L/s * .305m * 9.8 ≈ .19W Or a simpler approximation : flow (gpm) * head (ft) / 5.3 ≈ mechanical power (W) 350*15 / 5.3 ≈ 990W

[@johnstuart3851]

I noticed that Bill's system has a constant amount of air bubbles exiting at the discharge of the pipe in the lower pond. This means there is air being sucked into the system somewhere. It might be below the turbine. However, if there is any air leaking into the piping before the turbine, that will reduce turbine power and efficiency. With air leaking into the piping below the turbine, that decreases the suction at the turbine runner discharge also reducing system power and efficiency. There should be no air evident exiting the discharge pipe in the lower pond, the water flow from the system should not be visible.

Good eye. I would also add that this would not only reduce turbine efficiency, but turbine lifespan as well.

Seen this done with a washing machine spinner. He had plenty electric

[@someguy5035]

@@digimaks He has excess power in that setup. He could run more turbines easily or run one turbine faster. Faster = more power.

You could have free compressed air and refrigeration with that setup , just need a collecter on the bottom end

Amazing they sale electricity to you, for your home, and this is how simple it is. Electricity will be a luxury soon!

Very cool set up. Cogeneration is the key to a sustainable future. I noticed cracks in the concrete so i have some real concerns about the integrity of the dam itself.

[@vikipoyta]

if you want to talk sustainability let´s hope the dam cracks.

[@welders485]

So how bout putting a adjustment valve on the pipe to limit the flow so you don't drain the swamp . I can't believe I'm giving advice on how not to drain the swamp when I'm very much for draining the swamp.

Honestly the valve is already there... Just tweak the vacuum valve that you use to start it no? Ever so slightly open the ball valve, less flow in the pipe, more over the dam.
