Power from slow moving water

>>> Power from slow moving water

A new technology take on gaining energy from moving water. Being aimed at power generation from rivers and the like, I wonder if there is any future application for power recovery on sail boats and the like. Maybe even something for when you are anchored in a current.

VIVACE is the first known device that could harness energy from most of the water currents around the globe because it works in flows moving slower than 2 knots (about 2 miles per hour.) Most of the Earth’s currents are slower than 3 knots. Turbines and water mills need an average of 5 or 6 knots to operate efficiently.

Michael Bernitsas, professor in the Department of Naval Architecture and Marine Engineering, stands before a prototype of his VIVACE hydrokinetic energy device.

VIVACE stands for Vortex Induced Vibrations for Aquatic Clean Energy. It doesn’t depend on waves, tides, turbines or dams. It’s a unique hydrokinetic energy system that relies on "vortex induced vibrations."

Are Fuel Prices Changing Boating?

>>> Are Fuel Prices Changing Boating?

Mad Marinerâ„¢ has done a poll and article on how much fuel prices have changed people’s boating plans. A bunch.

Check the article for details and some links to a variety of builders who are beginning to build more economical boats.

A trial subscription to the site is available which gives you full access to try it out, or you can purchase a yearly subscription for a modest fee.

For full disclosure, I write some paid articles for Mad Marinerâ„¢.
