Gallery: Underwater Ocean Energy Turbine Harvests Vast & Powerful Marin...

The turbine has been designed to withstand the harsh conditions of the marine environment while minimizing impact on aquatic life. The high-torque, low-speed turbine operates at speeds similar to swimming fish and should not present any physical risk to life, and it also makes minimal noise so as to not disturb marine life acoustically.

    This is an excellent idea.
    I have two principal questions

    1) What innovations are in prospect in relation to linking
    these sea-floor devices to distribution grids?

    2) What is the minimum flow rate required? Tidal Stream is
    generally uneconomic below 1.6m/sec and around UK channel
    flows are often at 1.2m/sec or less.

    A paradox of the UK predeliction for wind-farms is that the
    public are increasingly calling out for harnessing of tidal
    energy. The goodwill is present – how can it be effective?
    Turbine design is one thing, implementation on an industrial
    scale with grid connections is quite another.

    This is not a criticism – but a genuine question as to how the
    overall scenario can be achieved, not just the turbine part.

    Crowd Energy is getting ready to re-launch on Indiegogo.

    Comparing this design, with its moving venetian blinds to other ones with simple rotors, I wonder how much more maintenance they would require. With flotsam and small animals getting stuck between those blades, they would quickly not be able to shut completely on their power strokes, reducing the efficiency of the system.

    Innovative! and I see great potentials in its ability to supply electricity in a harmless and cleaner way in a world wide basis.

    They should approach the government of Nova Scotia. There are huge grants for anyone who can harvest the tidal power of the Bay of Fundy, and the largest tides in the world.
