The people I have working with me on this project seem to think that a pulley system to spin the alternator at an appropriate speed would be effective.

I like the duo gen concept, I just don't like the price:) So if you wanted to build just a system to generate electricity what would you suggest? Obviously a system built off of a car alternator would be easy to assemble from off the shelf parts.

So what if we changed out the prop when we wanted to regenerate, or what about some sort of variable pitch prop? By the way this boat's average cruise speed is much faster than most monohulls. Over the last 120 miles sailed we averaged 7 knots.

Well the question always was "is the losses from all the compromises in said developmental syste Worth it based on the free electricity generated" I don't know the answer. I wonder what the actual percentage of loss would be based on one 90 degree turn...

That may be true, but I believe the only way to truly find out is to build it and test it. I beleive weight is a bigger factor thn drag but I'm not a hydro dynamics expert:)

Is the Torqueedo an ac or dc motor? I am under the impression that only ac motors can act as generators. I Plan on an outboard design with only the shaft and prop in the water.

I am aware of the capabilities of the torqueedo and some of the towed generator options. I had looked at a dual water/ wind generator called DuoGen, I really liked everything but the $4200 price tag :) I was hoping to find some expertise in electric motor tech to assemble what doesn't seem to...

I understand the benefits and limitations of electric propulsion. My last boat was an 18 ft trimaran that I equipped with an electric trolling motor and a gel cel battery. It was quiet and provided all the power I needed to get clear of the dock and raise the sails. I'm really interested in...

Hello all, I own a f 27 corsair racer cruiser trimaran. The boat is lightweight, incredibly fast under sail( capable of 20kts) and will do 7kts under motor with an 9.8 tohatsu outboard. I have been intrigued with regenerative electric drives since reading about Solomon technologies...
