Undergrad How can an vehicle move faster than the wind that is powering it?
I wonder why...let me know when you are ready to discuss the cart -

Undergrad How can an vehicle move faster than the wind that is powering it?
It's probably just semantics again, but if the boat is drifting with the current in air which is still (lets say relative the moon...) there will be a wind relative the sails. Exactly like a wind relative the still water. So in both cases you would actually sail if you have your sails up hence... -

:smile: I don't doubt that as it wouldn't take much to outsail a bouy tacking up wind now would it Jayson:wink: -

Undergrad How can an vehicle move faster than the wind that is powering it?
I'll answer That depends on your boat, sailing skills and whether there is a strong current going south directly to shore. If there were no current at all the buoy wouldn't go south as they seldom go directly against the wind... And even if there were a 10 knot current going directly to... -

Undergrad How can an vehicle move faster than the wind that is powering it?
Yes, that is what I mean. No wind relative the room, no wind relative the treadmill itself and consequently no wind relative the cart until it starts moving. So it's rolling, at the start it's standing still on the belt, propeller turning, driven by the rolling wheels as the belt rolls... -

What is it? I'm trying to have a discussion about a cart and you want to discuss sailing. I'm not sure it means the same thing to you and me. If you in A) as usual mean if an ice yacht can reach a point downwind faster than the ballon, then yes sure it can be done. Not sure how often tho... -

Then you have misunderstood me completely, I said it was impossible at first on RR, then I pondered about it and changed my mind. However I have a different approach to the proeblem than you do. -

Is the bet really your only agenda Spork since you keep on asking about it or is it pondering about a problem which seem to drive the rest...I'm beginning to agree with the guy that mentioned nigerian scam on RR...it's boring. -

Undergrad How can an vehicle move faster than the wind that is powering it?
No, not if you count in friction and apply those 10N on something also rolling on the belt. However if you apply those 10N on something that is standing still (the air) then that is a completely different matter. Spork actually gave a good example with a yoyo. Put it on the table with the... -

I've done my share of running on a treadmill, but I've never seen one that moves so that I've experienced any tailwind and I have had the belt going at more than 10 mph :smile: -

Doesn't a thrust reverser just divert the airflow? Just like on a water jet? -

Uh, the report says "in still air" did he misunderstand? -

I'm too slow :smile: And welcome aboard...finally someone that seems to be thinking in the same box as I do
