It look good, But you may want to start looking for a bigger motor.

Here is my experience was an under powered motor.

Alternator update

GM 40 amp Alternator, 1/2 hp 1750 rpm 8.7 amp motor
All on tap water, no additives, no circuit, with a 3" pulley on the alternator

3" pulley on motor, with 1 amp 12vdc power supply to rotor= 200cc/min
4" pulley on motor, with 1 amp 12vdc power supply to rotor= Alternator overheating
4" pulley on motor, running wire from stator to rotor=120cc/min
5" pulley on motor, with 1 amp 12vdc power supply to rotor= motor amped out
5" pulley on motor, running wire from stator to rotor= 175cc/min

back to 3" pulley on motor, with 1 amp 12vdc power supply to rotor.
need 1 hp motor next.
And get parts to build hydros circuit to pulse rotor.

Spike

Let us know how it goes

JR,

Great little series there. Thanks for taking the time to break that all down and post pictures. I'm sure that will help many people just starting out with this.

I also agree with Spike. You're going to need a bit more power when you start testing.
