Thanx for the info guys. As this is my first design, my blades are made out of 5/8" plywood and warped and bending due to the water, and my 1/8" steel sheet housing also warped when i did some welding so there is a lot of clearance everywhere (if it even makes a difference?
).
I think my first design direct drive dual rotor alternator and coil are also low in efficiency(i will need more time to test).If battery volts while charging are 13.5 and amps are 2.3,does this mean watts are 13.5 x 2.3 = 31.05 or
? If water flows over a weir 16.5" wide and 2.5" high,does this equal 14 L/s???
