The A7 diodes are 1N4007W - 1000V @ 1A and the MCC349B are 1A Zener diodes that they are using to clamp to maximum output to 12V. This limits to efficiency and at high flow rates (>12v) will load the wheel. I suspect on the 80V version the Zeners are not fitted.
sir i have submersible pump working 24/7 is it enough if e put 2 of water turbines to charge battery? if it is how many hours of 12 volts battery to fully charge?
I did not cut the plastic impeller open. I'd guess from their strength they are ferrite. If you make the magnets stronger, then start up force will be greater and it will require a higher pressure to turn. Also, to make this deliver more power, it would need bigger wires in the windings and better cores.
Not in a significant way if it is installed on a typical small family home. But I guess it would be useful if it is installed on motel or hotel, especially a high rise hotel with a hundred rooms and a busy laundry service!
Where do you see that? I gave it to a teacher friend already, but the input is a bit smaller, otherwise water pressure would build up and restrict flow.

Curious? If one would modify it by changing the tiny pre rectifier wires with a heavier gauge. Ohms law would support the theory.

@jeromeprado4497 No, as I said in the video, this is not practical for real use, it's only good for demonstrating the principle.
The main detail I would like to know is whether the magnets are neodymium or ferrite as this makes a difference in their performance

thanks for the video.
Pretty cool but I am wondering about its usefulness as well. Good testing though.
I concluded it's only good for teaching and learning, but not much otherwise.
Do you have any idea about what power scalability would be with increased waterflow
It's probably pretty linear up to a point, and I'd guess I was more than half of its max.
I have a question. Will this be able to trickle charge a car battery every time someone showers or use water?
Probably not any practical amount. A solar panel with a charge controller would be better.

The Input hole is very small than the output hole

@@tsbrownie Oh I think My one is faulty now I am sure the hole keeps small intentionally
