This Hydro - Dynamo is fron the late 1800's and mfg. by The Carlisle & Finch Co. (known for their early toy electric trains).
It has a water motor on the end of the unit where water was fed into the hole on the side as pictured. The water enters through a jet which increases the pressure. The directed pressurized water rotates a series of cupped wheels and the attached shaft rotates the armature where carbon brushes generates electricity.
The dynamo was set on the sink to catch the expelling water and the electricity generated from the dynamo could run small appliances using only the fast flowing water.
I knew that a dynamo can be either a generator or a motor. Depending whether you were turning an armature via a pulley, or if you were putting voltage to the brushes, you can make them do either.
I put a 12 VDC battery to the terminals and the armature started spinning. This tells me that if I would run enough water at the speed that the armature is spinning, I would generate 12 Volts. Thanks for your interest............ hotairfan.
