Why two watertanks? - How we installed a pelton wheel for hydro power

Many of you were asking why we built those two water tanks. In this video are some answers for you guys.
We installed a small pelton turnbine, to generate some hydro power for our off grid electrical system. For this we use the water from the upper watertank.
Also we wanted to collect water from a spring at the lower watertank and make if available up at the house. So we installed a pump here.
Enjoy.

Beautiful! I had never heard of levadas until now and enjoyed looking up their history.

for some top info on the turbine check kris harbour natural living, from what i saw in his experiments with optimizing such a generator the most serious "flaw" might be the material choice, metal is much more durable and the plastics from nozzle and scoops will get reduced into micro plastics in the water and cause serious contamination.. also horizontal setup makes for a batter drainage so the splashing water doesn't create unwanted drag slowing the turbine.. sorry for the lengthy remarks, at least you guys are doing it, trying and working towards a bright future in what looks like a very cool and wild place in nature... cheers and keep at it, all the best to you!!!

Good idea to. Prototype with plastic but as others have mentioned I would monitor for brake down of the plastic into micro-plastics.😊

Thanks for the great suggestions, will experiment more with this wheel and try to learn what works best for our set up. Some time will consider to get a metal version!

Awsum video! Have you researched ram pumps? They are amazing wonders which require no electricity. They are low volume so you would need to place an elevated reservoir.

70 W! Silly in the extreme !

Each one of the tight 90 degree bends you have used on your water pipes will be reducing the flow, can you find less abrupt bends? And voltage is not a measure of power, you need to be measuring Watt's.

It would be interesting to see how much difference it would make to mount the wheel horizontally with a less turbulent exit. I didn’t get the details of the pump up to the house but seems like a ram pump might work that would get rid of the necessity for electricity.

Serious stupid to house a Pelton-wheel in such a small box. Always mount the wheel horisontal, not vertical, so the "used" water does,nt hit the wheel and slows it down. Cheers from Sweden,, 🍻😎👍‍

If you increase the size of the hole the mass flow rate is not going to increase...it's always the same, because of the mass conservation law, greater area means lower exit speed but always the same mfr

Well probably you are right in theory, I can tell you though, that the generated power increased significantly when we increased the diameter of the opening. Probably the opening initially was simply too small. When the opening is fully closed, you get no water flowing, right? When the opening is a hair thin, then you will get some water sprinkling out, but it will not be as much as when the opening is the diameter of the pipe. So probably we were in this regime where the whole was almost "closed" in comparison to the pipe diameter and increasing the nozzle diameter helped quite a bit to reduce friction.

@@vale.do.salgueiro yes for sure there is a range of diameters in which the viscosity effect on the walls that appears as friction is predominant, what you say makes perfectly sense, thanks for sharing this example🤙
