Imi permit si eu sa comentez putin. In primul rand vreau sa te felicit pentru initiativa. Si eu vreau sa construiesc ceva de genul asta pe un rau putin mai mare ( si mai am in plan sa experimentez putin cu enerfia eoliana). Eu m-am gandit sa o fac mai mica si sa folosesc pvc pt ca e ieftin si nu rugineste :D. Oricum inca nu am nici un proiect, doar idei. Cred ca daca ai mai perfectiona putin ai scapa si de rugina si de pierderile mecanice. Oricum, succes in continuare.

Now OK, let's get serious
What u have are very promising micro hydro conditions (low head but high flow). Nice try, but this setup is all wrong!
Undershot water wheel is crap, you only recover a fraction of power. Use overshot by any means
You've got THREE transmissions, rusting, catching dust. Use a shaft attached to the wheel axle, some joints as needed and an ONE overdrive gear IN A HOUSING
Protect the wiring. Rainfall and moist surely trigger some tiny short-circuit losses

1.How can I go overshot with less than 2ft of head ? I can't modify the dam , otherwise , spring overflows could ruin the bridge.
2.I need to multiply rpm by at least 75x in order to properly use the car alternator.The only thing that isn't encased is the large chain.I plan to make a cover for it in the near future.If you look carefully , you'd see the case hanging to the right.

1. Maybe you should try to lengten this orange delivery pipe and put its intake much higher up the stream? And then install it nearly horizontally over, say, a hundred metres.
2. Try to replace a series of open chain gears with a cardan shaft attached to the wheel axle transferring power to some on-land closed bevel gears with high multiplication ratio. Then attach the generator to the output.
Power of 100W is virtually no gain. It's enough for a single bulb or a personal computer.

1. The pipe is 12" in diameter and costs $120 for every 13ft.I'm not sure it is worth it ; I'd could probably gain 3-4ft in head.Secondly , there's ownership problems ; I'd have to go over someone else's land.
2.The smaller chain drives a 22x gear based multiplier.
3. 100w is enough.I'm using a large battery ( 180A at 12V ).I can use 200-300w and at night the battery recharges.
100w is enough for 4 efficient light bulbs and 50w of music.That's all I care.

It is a 12V 50A car alternator , runs at 1100-1250 rpm.

Excelent prietene! Sa moara Korodi cu toti ungurii lui de ciuda. Aia nu dau autorizatii de microhidro nimanui (banuiesc ca nici asta filmata n-are autorizatie) ca sa aiba ei de unde lua pastrav pe gratis. Apropo, ca veni vorba transmit acelesi urari de 'sanatate' si Romsilva, institutia numerul 2 care pune bete in roate unor astfel de proiecte.

M-am informat la apele romane care ii faza ; nu ai voie sa construiesti baraje permanente ( aka beton ) si/sau prea inalte ( al meu are 0.5m , pastravii il pot sari , nu m-ar mira sa intre si in tub , roata fiind ridicata cand nu functioneaza ).
Al meu este construit din gabioane cu pietre , in plus , se colmateaza dupa viiturile de primavara si devine un simplu prag.

Treaba cu barajul permanent e un fleac. Il faci din gabioane si gata, vorba ta oricum se umple cu balast la fiecare ploaie mai tare. Ai sa vezi in schimb ce circ iti fac daca vrei sa dai curentul in reteaua nationala... Oricum ma bucur ca exista interes pentru asa ceva in tara, baietii de la Hidroelectrica nu se sinchisesc de centrale sub 500KW.

Da e roman! E din Romania.
