An impressive site with lots of various technology, boats, ideas and links. The walkthrough of the boat is impressive with details of the technologies and pictures.
Interesting article covering wave powered, remote controlled robotic craft. A set of them are well on their way toward crossing the Pacific, while others are gathering data in the oceans around the world.
End of the article hints a bigger models to come. People have been traveling on "slow boats" for 1000’s of years. Wonder if it will come back around someday.
The world’s last surviving wooden whaling vessel, the Charles W. Morgan, is being restored to sea-worthy condition again.
The above image is taken from a laser scanning system being used to map weak points and provide a detailed 3D reference model of the vessel.
Who needs to build a boat when it can build itself?
You always knew those paper shapes you played with instead of paying attention to the teacher would come in handy.
Was at the U.S. Army Transportation Museum at Ft. Eustis, VA (a very well done and extensive museum that is well worth checking out) and saw many historical marine craft. Never thought about how much the Army has dealt with marine craft and technologies. Landing craft, tugs, etc. all played a huge roll.
Anyway, they had this Vertical Axis Propeller on display. I have seen studies of these in much more recent times, but didn’t know they had been tried and tested back when. Kind of a Z-drive without the Z… I can see some issues with trash getting tangled, maybe, but…
Well, not really a propeller, but a mechanical "flipper" being studied by some MIT students. Check the film:
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."
