sailboat generator
« on: November 03, 2007, 11:00:22 PM »
   How about putting together a fleet of specialized sailboats that work the tradewinds. These sailboats, able to capture thousands of horsepower from a 20knot wind, hydrolize seawater and compress and store liquified hydrogen.  Once full, sail into port off load and go get some more.  Right now there is a storm over new england and this baby is generating enough wind energy to power the region for the next year.

Kind of like going out to fish for energy, filling up your cargo hold, and coming back into to market to unload.

G'day all,

Can someone explain to me how these sailboats are supposed to harness wind power. On a sailboat moving with a 20 knot wind there is NO WIND! The boat is moving at wind-speed, the air on the boat itself is perfectly still.

You can only harness wind with a boat for power generation if you put the boat at anchor. Land is much better for this sort of thing, it is more stable.

Now you make me giggle Hans. How could you say something like that? No boat ever moves at wind speed man. LOL! You are joking right? .... pfff I guess not! haha

It reminds me of that time I tried to have a discussion in a sailing newsgroup about sail cars and sail trains. The sailors insisted the wind had to come from straight ahead making the train unworkable in their opinion. ROFL talk about being uninspired??? WTF?? Those where sailors for crying out loud. I'm still recovering from the shock...

The reality is that you can even sail directly upwind.  That would be the only angle where the boat goes slower as the wind. lol

I think this is a great idea. Put wind turbines on a barge if you want to.

In my experience the only time there is no wind from the boat's perspective is when sailing downwind, and top speed is limited to the actual wind speed.

Sailing off the wind you will always feel the wind, and boats that can sail very close to the wind can actually move faster than the wind. Their own movement adds to the wind.

It does seem like you would have to sit still though to best harvest the wind.

But wouldn't you get the most wind power into your wind turbine if you were as stationary as possible?

Sorry Ken, this is exactly what I meant, looking back at my post I didn't make myself clear. :-(

@Hello
Please dont mix Properties of a air balloon with a Sailing drive.
The Solution is quite easy.It depends on the direction,that you move.
"Wind"discribes in this case" mobilised Air"
If one move with the the wind,isolation occures.
If one is not moving with the wind,then the wind is able to work.

But one never moves "with the wind". the suggestion to sail in this direction is already nonsense for a normal sailboat. If the idea is to use the wind to generate power then it becomes even more weird. lol

Depending on the boat design it "ideally" sails roughly under a 90 degree angle. A wind harvesting sailing boat would logically be build to sail up the wind as much as possible.

Let me draw you an image.....

@Gabi
Dont forghet about the Hot Air Balloon Driver.
The Wind is moving the Balloon.
And a Sailboot can not be moved frontal against the Wind,but can be moved backward with the help of the Wind.
But dont believe what i tell you...better take a surfboard Lesson next Summer in Lemmer,Makkum or Renesse.
Just feel the Wind and enjoy the Power.

Right click the image then pick "copy image" then you go to M$ paint and liberouslly add things to the illustration.

"sailing close to the wind": nearly opposite to the direction from which wind  is coming;
http://dict.die.net/close%20to%20the%20wind/

That means 2 times as much wind.

lol

See the Sketch
There is no Way to move frontal forward, against the Wind.
To come forward against the wind it wokes  in step shape only
But the Windgenerator will work fine.

I think it should also be possible to use the compressed air coming from the sail.
