The web master posted notice of some new technology at http://www.yachtforums.com/forums/ne...iven-prop.html but it didn't permit one to reply there.

So I thought this subject matter might well be integrated in this subject thread as it appears as though there are some number of new 'Peripheral Driven Prop' arrangements coming on line and/or being researched. These concepts lend themselves well to the electric driven concept.

I posted this message on another forum today,

"Exciting New EPS Thruster (& Propulsion)"

The results of the Design at METS awards, announced at this morning's Breakfast Briefing, appear to prove that the wheel can be reinvented according to the Jury, who named the EPS Silent Thruster from Van der Velden Marine Systems of the Netherlands as the overall winner.

This product redefines the bow thruster, eliminating the usual arrangement of a central hub and gearbox. It instead uses exchangeable blades that are connected to an outer ring; this floats on ceramic bearings and is powered by an integral motor in the casing. The solution is elegant, well designed, and promises a number of advantages over conventional concepts

In addition to fixed thrusters they are now working on retractable systems as well as utilizing the concept of the EPS as a means of propulsion !!

I posted this as well, "Maybe the ceramic bearings aren't all of the technology that has allowed the emergence of this new propulser. It appears as though the preipheral drive power is an electric motor of some sort integrated into the outer ring. This would make sense with all of the new talk of diesel/electric systems."
