Thanks gwb. It's a bit of an off topic here on Elite, but there are science and physics forums with threads and posts totalling more than 100K....

For those in Canada, a segment on this topic is being aired today on the Discovery Channel's Daily Planet show. JB
Thanks, it is a fun topic for some ... very frustrating for others. So I can better respond, would you mind being more clear on which video you...
I'm quite certain it's a proof of 'directly downwind faster than the wind', rather than 'push and pull are the same'. But then that's just me....
Here's a recent write up in Sail Magazine (the issue will be on newstands in the next few weeks)....
Hi Wayne Actually, it's a *turbine* cart that can move directly upwind, rather than a propeller cart. Conversely a turbine cart can't...

I was actually at the game on Sunday when Aston Villa knocked Newcastle out of the EPL. Just got back to the US last night. The score didn't...
Well, in the above exchange (all posted months ago), I don't believe I managed to convince a single person that it's possible to build a wind...
Well, first off a little one works just like a big one. That's exactly right if you are sitting on the cart chassis. However if you were...
Haroki, I know this may sound silly on something so simple -- but you're pretty sharp to catch that above. Of the hundreds I have discussed...

You'll have to explain the "problem" with the remote steering. Nope -- from the side it was filmed you just couldn't see that there is a long...
Yes I am. :-) Here is our entry into the MythBusters Video challenge. http://www.youtube.com/watch?v=4GOlSi-2p3g JB
Hi haroki. It's powered by the differential movement between two mediums. If I put it in the wind tunnel, it's the electric motor moving the...
Yes, and on the other end of that equation is the prop -- and the wind can "couple into the vehicle whatever is needed (within the limits of the...
You do notice the "powered by the wind" requirement in the original statement don't you? JB
Wayne, it's impossible to be "introducing essentially unlimited energy" into the system -- the device can only absorb as much power through the...
Uhhh yes. LOL -- your rollers simply don't have enough inertial resistance to throw you over the handlebars. If the earth was as light as your...
