hydrogenerator

[gyls]

Hello,

I am looking for as much information as my friend google can provide me, on the hydrogenerators.
In detail I research the principles of operation, design of propellers, efficiency of the multipliers, operation of generators ...

The goal is to put it on a sailboat, so I'm looking for a system that can not be optimized as a couple, like the classic hydrogenerator or wind turbines, but that can be optimized in torque / drag ratio in order to slow down the boat to a minimum for a given production.

I hope I have been clear in my request and be on the right subject.
Thank you for your help

Hello

See at leroy sommer in vitre, they equip sailboats engine / hydrogenerator.

but not wake up that will "cost" you at least 1 knot.

thank you for this answer.
The principle is that I want to develop a specific system with a propeller dedicated to the hydrogenator and optimized for the production of energy.
The loss of speed is not a problem, but I always remain in the same optics of optimizing the loss.
Moreover, this system must work between 3 and 30 nodes or it does not exist in the trade, that's why I'm looking for information on the very design of the system ...

In addition, this system must work between 3 and 30 nodes

If you need a system that works at 30 knots, it is to equip a pedal boat.

so a boat with a light sampling.

do not dream from 10 / 12 knots efforts are such that nothing will resist, you will need a system of disengagement or blocking of the propeller.

my pedal boat is a 60 open feet, with the sample that goes well to hold up ...
The operation at more than 20 nodes is necessary because one is often at this speed, but most of the ones of the trade drop at more than 10 nodes, that is why I reconcile ...

I hope I scared nobody ... because since I made this post, no more one answer ... you really have no information ...
