High Tacker just mounted a conventional land based turbine on a catamaran. Not the best way to do it. He created a monster. It worked but was...
I often wonder, in discussions such as these about the intricacies of exact angle of attack of aerofoils (airfoils). That an assumption is made...
High Tacker I've now asked the same question twice, and this is the third time. If you can't think of an answer please say so. Maybe you are a...
You didn't really answer my question, maybe I didn't make it clear enough. Yes, quite true that drag increases with speed, but so does lift....
Typically, aerofoils produce more lift than drag. (By a large margin). Increasing speed does not affect the lift to drag ratio. Can you explain...
You are certainly right Jeremy about the blade issue and what makes an efficient turbine. But I can't help thinking that a design such as the...
You have certainly put "Windmaster" straight on a few points. However, I followed his linked video http://www.youtube.com/watch?v=8Rw_qJytbG8 . It...
It should at least have a wingsail!
We've also been over and over the fact that it was made then etc. etc. (many times). That is not the point. It doesn't mean we can't consider it....
Yes, but the sailboats are not sailing direct to windward are they. However, if you sat in the middle of the plank?
It's now relevant since Windboat the OP has expressed interest in it. Therefore his thread is not hijacked. The boat that Jeremy has envisioned is...
Your partner only sought to set the record straight after you had been "found out" by Windmaster. You were perfectly happy to allow the forum...
Your "brain teaser" didn't appear before April 2006. You cannot show anything to prove otherwise. To suggest that Jack got the idea from you is...

They did do it. But wern't the first. I think that's what Boston means. Despite not being the first, they were very eager to take the credit when...
That's true. There were at least two people who did it before. One was a ride-on machine and the other more recently was demonstrated in model...
It might be better to mount the wind-turbine on land next to the mooring (I know not all places are suitable for this). Then when the boat is...
This reminds me of the downwind faster then the wind dispute. The people who suggested this idea were pounced upon by nearly hundreds of "experts"...
I'm sure Windmaster would like to be credited with going downwind faster than the wind. But it wasn't he who did it. You are trying to compare...
So who has done these tests to prove its "not practical"?. Windmaster has done tests to prove it IS practical. How can something be "not...
