Hi,
For my University Project I have to create a working Tidal Turbine. I have chosen to use a Vertical Axis one, which will allow all the electrical equipment to be placed above water.
I have been successful in the Mechanical building part of the project so far. But I am very stuck on converting the mechanical energy into electrical.
Due to tidal energy, I am struggling to find a motor/generator that will produce energy at very low RPM. I have seen that Permanent magnet motors or Permanent magnet Alternators are best to use, but do not know which would suit my needs best. I have looked into gearboxes and have found references to Planetary gearboxes being used with wind turbines.
I am also struggling to understand what is needed in order to transfer any output voltage from a motor/generator to a large deep cycle battery of perhaps 24V.
So far I have found a 24VDC Motor with a Planetary gearbox connected, I was wondering if this would be suitable?

Due to it being a university project, I have a limited a rather low budget.
I would greatly appreciate any help,
