DIY Micro hydro power-Off Grid Day 35

We finally install the micro hydro turbine. We run the pipe from the top of the hill, assemble the micro hydro turbo turbine and build a house for it to sit in while putting together some cheap intakes to filter the water inlets. We turn the turbine on and show what figures the turbine outputs in watts and volts as well as PSI figures.

[@philelliott3683]

Very innovative well done. Can’t wait for part two🎉🎉

[@offgridscotland]

thanks, super keen to get it running properly so only waiting on the postman for part two

[@tinkersdug1969]

It's good to see it working. As for the leaking, you can't expect to get it perfect. First, try well done so far.

[@offgridscotland]

Thanks! I have ideas as to how I will rectify the issues for the next video

[@andybrown6179]

Exciting video. Can’t wait for part 2

[@offgridscotland]

thanks, really want to get it running properly so it won't be long before part two

[@oneorangedog]

Well done, a pretty good result for a first set-up.

[@offgridscotland]

Thanks! Hope I can squeeze some more out of it

[@neilclarke6419]

Good effort Rob I recon the vid doesn’t do it justice how much work you put in! Looking forward to the next one!

[@offgridscotland]

Thanks, It was a lot of work but most of it was head scratching

[@LukeTimms78]

I've just stumbled on you looking for foam wall panels. Now You're added to my list to binge watch when the wife falls asleep :D

[@offgridscotland]

Thanks a lot! I hope you like the rest of our stuff as it has changed to off grid since the foam wall panels

[@UKsystems]

Great video, I would recommend when rebuilding to put the box to the side and plumb in a drain due to streams overflowing and erosion.

[@offgridscotland]

Thats a good idea, I can easily shift the box as its not anchored down yet

[@mikemcdonagh2049]

Well done mate. Great stuff.

[@offgridscotland]

Much appreciated

[@toxirjongapporov9794]

Do you have a phone number?

[@markmacleod6971]

You should use a 4 inch pipe to run down from your water supply inlet and then split it off right at the bottom into your 2 inch pipe that go to your turbine nozzles. You will get more pressure thus more power

[@offgridscotland]

I agree, I think for version 2 that is exactly what we will be doing

[@quantumenergysolutions9128]

Well done , Very Nice! Im thinking , you could modify it to become way way better if the housing could withstand pressure, It could also be the tank for a Trompe air compressor, and with that air connect a Tesla turbine, or other work? Just add straws to the intake to add air.

[@offgridscotland]

I am looking forward to having a play with it. To be honest I wasnt sure how much power we were going to be able to generate from this so diddnt want to play around too much until I had a baseline to work from

[@happyglampers9053]

Brilliant Rob! I had a grin as big as your land when the hydro started spinning up🎉👍👍 That hill will definitely keep you fit too 😳👍👍 Keep up the fantastic work 👏👏👏

[@offgridscotland]

Thanks, I wish I had put a stopcock at the bottom as well as the top so I didn't have to run up every time I needed to turn it off

[@norfunk]

You might need to add a breather tube on both pipes to let the air out, it's just a vertical pipe on a t-joint that with the air outlet above the inlet. Have you checked the ltr per min of your streams as your pipe looked a bit thin as well.

[@offgridscotland]

thanks, I had two vertical t joints per pipe but the water was just pouring out the top and they were 2 metres tall! I have a solution that we will be putting in the next update though. Pipe is rated for 6 bar so I seem to be ok with that. The higher pressure pipe was so much more expensive so I thought I would replace the lower section if its not up to it

[@norfunk]

looking forward to checking out the solution.@@offgridscotland

[@daunispierre1514]

Franchement, j’appelle ça, une véritable beauté Hydro électrique😂😂😂 l’amour de ma vie. Son nom de famille c’est Pelton.😂😂 En tout cas bravo pour l’installation mais j’ai survolé un peu rapidement. J’ai pas vu le régulateur qui recharge la batterie avec l’onduleur derrière.?????

[@offgridscotland]

Je pourrais passer à une roue de peloton pour la prochaine vidéo. Voici le lien vers la partie 3 et également notre installation d'onduleur kzbin.info/www/bejne/gn-wooaaf52VkMk kzbin.info/www/bejne/eqGceaKij6xqaJY

[@mangjay80]

Nice land nice turbine

[@offgridscotland]

Thanks!

[@bethrand9292]

If you can find or make a square gasket for the bottom of the blue box it will stop the leak.

[@offgridscotland]

Thanks I actually ended up deciding that today filming the next video. Great minds think alike

[@velocityfpv5231]

i'd put 2 or 3 catch cans at the source and send them into Y joiner to get double the flow without stealing all of the stream. Really cool though I wish I had some land like this

[@offgridscotland]

Thanks! I will keep the catch cans in mind as I am sure I will be refining the system as we go

[@michaelmason5459]

Out of curiosity if one pipe/jet as less pressure and the other is spinning the paddle faster than the other won't it be pushing it through the other jet of water causing it to act like a brake giving less power. Could joining pipes together higher up then splitting it lower down into botn jets minght equalise the pressure on both of them both spinning paddle same speed If that makes sense

[@offgridscotland]

I had wondered if it would have any affect but it doesn't slow the turbine when I turn the other on and I think as they are on opposite sides of the wheel they don't spray at each other much. I will definitely be seeing an eye on it though as we are still testing it.

[@quantumenergysolutions9128]

Now with the low cost, light weight, solid state Fractal Capacitor Array @ 94% efficient (see Robert Murray Smith)you can transform/rectify LV AC or DC into HV DC send it real far , then transform back down to LV DC, For any application. If using plenty of high Farad Ultra caps, The array can be the battery bank/ Buffer!

[@offgridscotland]

I watch so much of Robert Murray Smith!

[@johnhutchinson5265]

I will calculate everything for you over the next few days once we get Christmas out of the way.

[@offgridscotland]

Thank you very much, although don't spend too much time on it as I don't want to get in the way of your time off

[@UKsystems]

just a tip replace the rubber couplings with MDPE fittings personally i find pipestiock the cheapest

[@offgridscotland]

Thanks in part two I have done exactly that

[@quantumenergysolutions9128]

Is it not a good idea for the output pipe to be much lower in the housing, and the housing to be deeper , so the turbine can never hit the water level?

[@offgridscotland]

Yea maybe, I actually wonder if powerspouts pelton wheel might be better for us on our next upgrade as it is a completely different shape

[@christophe3195]

The turgo wheel support is very pressed into the shaft. Didn't you put the key in?

[@offgridscotland]

I did put the key in, in the instructions it said the key needs to be shortened by hand because the keyway isn't long enough for it.

[@GucciGang1285]

Anyone know what type of motor this is? I can’t seem to find them anywhere and the link in the description is out dated.

[@offgridscotland]

it is the MOTenergy brand of turbine but I think they stopped listing it on eBay so you have to go to their website now www.motenergy.com/hydro-power-products.html

[@guygillmore2970]

Where did you get the turbine?

[@offgridscotland]

Bay but it was from America and shipping and tax was quite a bit. I have added the links to the description

[@FredSayers]

Two lines to turbine so you are not putting side load on bearings two lines 180 degrees apart

[@offgridscotland]

Thanks

[@user-hy8ih9nr6n]

Where did you get the turbine? And kit? Please

[@offgridscotland]

It was off ebay but I think they stopped selling it there but here is the link to the manufacturers website with it on. www.motenergy.com/hydro-power-products.html

[@user-hy8ih9nr6n]

@@offgridscotland thank you very much 😊 have a great day 😊

[@udos46]

minuto 5.07 : look at my logo: if you don't put a glued sleeve (I use the one they put on car windows), water will get into the bearing use a fixed injector or change the ring of the double plug: it has an exit hole that is too large and the spray is bad,

[@offgridscotland]

Thanks for the tip I hadn't considered the sleeve and someone else had also mentioned the poor spray of the nozzles

[@perryvallee3643]

Is this a Kit that you can buy.

[@offgridscotland]

You can buy the turbine kit yes the link is in the description. The other parts are also linked and aren't hard to combine into a full kit

[@Jkauppa]

Try open/closed tesla turbine, much easier to make diy. Instead of the pelton turbine, direct replacement. Also easy to make from more durable metal, from steel sheet, washers and rivets, and axle.

[@offgridscotland]

Thats an excellent idea! I will add it to my project list

[@toxirjongapporov9794]

[@johnhutchinson5265]

The bore of your penstock is far too small, the frictional losses are significant. With your static head of 70m & a penstock length of 250m with a bore of 40mm the available head running 1l/s = 65.3m, 2l/s = 57m, 3l/s = 44.3m, 4l/s = 27m & 5l/s = 6.67m. Unfortunately you will be disappointed with the available power available due to really high frictional losses due to the small diameter of penstock over that length. Ideally you should have sought some technical advice prior to purchasing the penstock.

[@offgridscotland]

Thanks for the advice, I wanted to do it myself rather than go through the hullabaloo of seeking professional advice, as well as the cost associated with it. I also didn't want to use too much water and run the streams dry so I am ok with lower power. Sounds like you really know your stuff though!

[@johnhutchinson5265]

Hi understand you wanting to design and manufacture your own micro hydro system without seeking outside help but as you can see from the above figures the more flow the more head loss due to the long penstock and relatively small bore. Is you penstock actually 40mm bore or 40mm outside diameter? If you can accurately measure the bore I can give you a more accurate figure for head loss at different flows. You say 70m static head on one penstock but what is the head from your other stream? I can then deduce what actual power you should achieve from each penstock and which flow rate will give you the best efficiency. Regards, John@@offgridscotland

[@offgridscotland]

Thanks John, Its 6 bar 40mm pipe so the ID is larger than a standard MDPE would be but it's not 40mm, more like 36mm. Both heads are 70m but I won't be using more than 1-2lps per stream. We get 80psi per line at the turbine.@@johnhutchinson5265

[@johnhutchinson5265]

I worked out the frictional losses based on 70m head using 40mm bore so therefore using 36mm bore the head losses will be even worse than the original figures I sent you yesterday. I will work them out and let you know. You will probably only be able to use a maximum flow of 2l/s otherwise the head loss will be significant. I will also work out your potential power available at different flow rates so you will know which flow gives the most efficient outputs.@@offgridscotland

[@alabastardmasterson]

John Hutchinson is correct. You're going to be very disappointed with your output and there's no need to have 2 nozzles with that diameter pipe
