    What do you know about the waterotor wave and water technology?

    “To produce any useful electricity, the relatively slow up and down oscillation of the tides and movements of waves have to be transformed into a single mechanical output that can be used to rotate an electrical generator at hundreds of rpm, which in itself will require some form of gearing mechanism”
    – this used to be the case, but today it is posible to use permanent magent generators that run without gearing.
    Generators with neodynamium magnet are used on many new wind power generators…

    • Hello Bjorn, Both permanent magnet generators and generators with electromagnets can be used for the conversion of the mechanical power into DC electrical power which is then converted to AC. These low speed DC generators using rare−earth cobalt or neodynamium compounds and electromagnet stabilisers can be expensive. A cheaper permanent-magnet alternator or an AC synchronous or AC induction generator are more cost effective and can be directly coupled through a gearbox or belted to increase their rotational speed.
