This is a very simple micro hydro turbine array that I built using six (12 Volt 10 Watt) turbines. I still have to add blocking diodes and do the wiring on this particular array but when testing an array of just two of the turbines I had pretty good results. The turbines themselves only require 7.25 PSI (or 0.05Mpa) to start generating electricity. The individual turbines themselves can be purchased online for roughly five dollars USD which makes this a very affordable project.
Specifications of the F50-12V micro hydro turbine generators that I use are listed below.
The output voltage :12V
between the wire resistance 10.5 ± 0.5Ω
Insulation resistance 10MΩ (DC100 megger)
the maximum pressure 0.6Mpa outlet closed (87.0226 PSI)
the outlet opening maximum pressure 1.2Mpa (174.045 PSI)
Start pressure 0.05Mpa (7.25 PSI)
Mechanical properties and the operating environment:
axial clearance 0.2-1.0mm
mechanical noise ≤55dB
the weight of the Generator : 90g
generator life : ≥3000h
