I want to use it for propulsion. Yes it would not be powerful, but I do not like boats with powerful motors. I laugh at people who are impatient and use gas motors. I also get pissed when I see people motoring when there is more than 3 knots of wind (watch out I'm getting torpedos) Dont want to hear them or smell their fumes.
Currently I have a canoe paddle to power myself when there is no wind. I suspect the wind generator would provide comparable thrust which would relieve me of rowing. This would give manoeuvrability in tight areas and the ability to move the boat slowly without a trolling motor
. If I can work out the electronics
, I believe it is just a switch to bypass the control circuit board (disconnect it) and apply power directly the the alternator
A lot of my ideas so far that I have posted (like repairing sails without sewing, packing my displacement
boat with styrofoam to make it unsinkable etc...) got some funny
responses and only a few people even considered them possible. I have done all of them (and a lot more weirder things) with success and I think I can again with this too. The main reason people might try this is, they already have a wind generator, so the cost is $0 and it gives another means of propulsion.
Unfortunately I seem to be much faster at thinking up stuff than implementing it, I'll post and update when I get it working ;-P
I did not think about aiming the wind generator at the sail, I don't think this would have a very useful effect but maybe there is something to it that I have not realized. I like it when people think of stuff like this that I overlooked.
The fastest human powered boat used an air propeller
. It had the driver pedal to make it spin, and the boat achieved speeds of 18 knots on hydrofoils. It can be very efficient, but the blades probably need variable pitch
to get good efficiency at all speeds.
Am I wrong to think that in theory it is more efficient to use a air propeller
propeller if the wind is dead and you are traveling against the current
? This would be assuming ideal propellers and maximum efficiency.
