"What’s your energy innovation?"

see more ideas like this.

I propose a simple and efficient low drag turbine following the logarithmic spiral configuration found everywhere in the universe from hurricanes to galaxies. This new horizontal axis turbine is very practical and can generate a lot of clean energy. It’s also cheap and easy to build, requires little maintenance and works most efficiently in water currents (no damming required).

The goal of this project is to have a cheaper and cleaner way to generate electricity, especially in developing countries and remote villages. The blades may be built from recycled plastic bags and bottles, saving the environment on through both manufacturing and use.

    How do fish react to these turbines?

    Thank you for your comment Susanna, this turbine is supposed to be safe for marine life; fish and other living creature slides in through the blades when going down the current. they might get a little dizzy but they will make it :)

    Creative thinking! Similar to the Eco-Auger

    also a spiral
    also fish safe, a good idea
    all these are hard to hold in place, however since the axis is parallel to the current, you need a boat or raft to hold it.

    Burt: Why would it be hard to hold in place? Since the axis is parallel
    to the current the tether point will always be upstream. If the direction
    of the current changes the tether point will still always be upstream.

    Since the generator is in line with the axis there is no problem. Any
    power or other cables are flexible and go from the tether point to
    wherever. The tether point can be secured at the bottom or side
    of the channel or in case of a wind application it can be secured to
    any available surface where the wind blows and the turbine has
    freedom of motion.

    Its good idea,
    insted of using as turbine, better to ues it as a propeller for boat or ship might be a big success.
