What about the Tesla Turbine run off of hydraulic fluid?

I am working with a friend who needs something like the "e-pod" and we would like to hear everything we can from those who are using it.

On the electric boats site refer to message 12098. Also see message 11913 and under that one I suggest a read of 11932.

I am not suggesting anything negative, simply suggesting thinking about the opinions of folks who have already walked the walk.

Thanks for the "heads up", Merrick. I checked the messages you noted as well as other postings at the Yahoo site. Until that 12098 posting I hadn't heard of any problems with Re-E-Power or their products .... quite the contrary. I alerted the company via voicemail and hopefully they will reply to said posting.

I did locate another company (Bellman) BELLMANN Drive Technology - Mooier kunt u niet varen with a similar style product ("AquaPod"). Bellman has recently been acquired by Mastervolt.

I am in a holding pattern until things shake out!

Correction: Mastervolt became a part of Bellmann. The AquaPod looks like a high quality product .... I don't have any pricing info.

I have been looking through the Bellmann website and they have a wide assortment of marine electric motor types including AC units. The pod versions come in an assortment from retractable to rotatable (steering) to surface mounted. Also they appear to have serious 3-bladed propellers on the pods versus the "trolling motor" type props.

sail=catamaran,primery power=sail,secondarypower=outboard(4 stroke only), or tons of batteries & 2 eletric motors,but unlike monohulls catamarans don't use ballest so you figure it out.

Monohulls = sans training wheels

I just read the following on
Green Car Congress: Researchers Develop Solid-State, Rechargeable Lithium-Air Battery; Potential to Exceed 1,000 Wh/kg


Researchers Develop Solid-State, Rechargeable Lithium-Air Battery; Potential to Exceed 1,000 Wh/kg
21 November 2009

Sample UDRI solid-state, rechargeable lithium-air batteries, and Dr. Binod Kumar.
Engineers at the University of Dayton Research Institute (UDRI) have developed a solid-state, rechargeable lithium-air battery. When fully developed, the battery could exceed specific energies of 1,000 Wh/kg in practical applications, the researchers wrote in a paper published online 13 November in the Journal of the Electrochemical Society.

Styer told me March '09 they were looking to add a regenerative option to their system by the end of '09. I've asked them for an update and they have yet to respond.

http://www.steyr-motors.com/products/pdf/hybrid.pdf

"Intended initially for displacement craft between 1.5 and 20 tonnes using Steyrs own diesels of between 55hp-285hp, DEHS interposes a 48V motor generator between the engine block and the gearbox. This provides three propulsion modes: plain diesel; pure electric, and boost- during which both the diesel engine and the electric motor drive the propeller - normally for short periods of acceleration. Whenever the main engine is running the generator charges the battery bank. It is also used to start the main engine, eliminating the need for a separate starter motor."

There is a Steyr parallel hybrid on the newly launched Zogo, built by French & Webb in Belfast, Maine.

I was able to supply the LiFePO4 battery pack which saved them about 600lbs while adding about 20% more capacity than they would have had with AGMs.
