Hi All.
Ok, I found enough data on the turbine to clear this up asp.
First of all if you seen the Video where Greg Potter was showing the system running with the top off, you can clearly see the turbine generator cooling fan not turning.

This is the turbine:

Pelton Wheel and PMA Generator set. These two products were designs to work with 1000 to 3000 watts output, from 12 to 36 VDC for charging batteries in Home Power systems. Note that this is an AC generator and you need to purchase your own 3-phase full wave rectifier to convert the AC output to DC for charging batteries. You can find 3-phase rectifiers and Charge Controllers on our site
Pelton Wheel Part Number ME0903.
PM Generator ME1016 Rev A.
The Pelton wheel has die cast aluminum cups for many years of product life.. There are 12 cups. The generator uses Ceramic magnets and has over 85% efficiency, much hither than a standard car alternator which is usually 60%. The Pelton Wheel mounts directly onto the PM Generator shaft with 4 x M5 mounting bolts (bolts not included but can be purchased from Us or a local hardware store).
Designed for use on your own Pico Hydro Projects. You will also need to build a water box and add a nozzle, plus you will need a 3-phase full wave rectifier and a charge controller.
Easily provides 1000 watts of power with one nozzle, 2000 watts with two nozzles. With one 3/4 inch nozzle and 28 PSI (65 feet), 80 gallons per minute, it provides 500 watts output. You can add up to 4 nozzles.
So if this generator produce 500w of power it says that you would need:
28 psi @ 80GPM = 500w output
But:
28psi x 80gal/1714 =1.3 hp or 974watts to produce 500 watts where is this free energy?
I see it this way, input 975w and waste this energy to produce 500w output not something anyone would buy.
I will not comment on this GDS project any more, It's a waste of time.
