I don't get how it works. the explanation was not very good. So the wave hits the fin and then what???

Tom, think of how a dolphin or whale moves when they flip their tails up and down. Or how you move in the water by kicking up and down with your swim fins...

This explanation is in the link in the middle of the page that my link takes you to.

"Wave powered boats feature fins at the front of the craft, which generate thrust force by moving up and down like the tails of dolphins and whales and absorbing the energy of the waves."

I guess the only difference between one of these and a whale is that you don't have to stay 100 yards or miles away from it legally! Rolling Eyes

It's also got solar power for the electrical stuff, just uses the waves for propulsion.

ok I'm not getting it. the wave hits the fin and the fin goes up and then what?? it turns a pump or a prop or what. a whale is not moving from the energy of the water hitting him. Hes moving from pushing with his muscules against the water. so I am just not getting how this works. are the fins spring loaded and push back after the wave moves the fin up?? I need drawings and crayons.

Here is a link which shows how it works:

Horie is a very accomplished boating innovator--and has taken some "unusual" boats across the Pacific. I suspect he will make it...assuming good weather routing. I think that if one was bucking into a heavy storm an seas, that there would be both danger to the vessel, and the possiblity of not making headway....

I agree with those who say that sailing is easier, probably costs less and is faster.

OK Tom, I'll try again too.

CHECK THIS OUT

Now, instead of a human above one of those puppies, imagine a 30+ foot boat bouncing up and down in the waves....

Get the picture? Idea

Well, today I filled up the Ford Hybrid at the Safeway, $3.25 a gallon with a 10 cent discount. I noticed a sign on the pump stating that all Safeway gas stations are wind powered, in that Safeway somehow purchases thewindpower. On a day when the Dow lost over 300 points and oil topped $103, I do feel the time for wisecracks is fast ending. More people may be going from 90 to 75 hp on 22's and 50 to 40 on 16's. It all adds up.

I'm with Tom on this one, I don't get it...the wave hits the fins and...what? The videos on the other site all had the rider pumping away, again with some kind of muscle power, to move whatever was below the water line. It would seem like waves hitting a fin would not, you know, do anything...but of course they must.

Ok that away. its like I said a spring is the driving force. the waves compress the spring which stores the energy then releases the energy by pushing back. That's what I was thinking it was, but no were in the articale did it say that. Which is no suprise, most news I read these day's are just fluff and little info. Good luck to the sailer and maybe this will lead to something but a nuke reactor is better and we already know how to do that. Seem a lot of effort being spent to power ships, home, buisness etc when we already have a cheap clean means to do so.
