Re: [Phys-l] Wind Powered Vehicle speeds downwind



Very interesting. Thanks for posting!

Explanation on the original site was somewhat cryptic, but there is a physics related blog discussion here:

Quoting Brian Whatcott <betwys1@sbcglobal.net>:

An object that apparently excites physicists' emotions...a wind yacht
that goes downwind at
wind speed X 2+

(Which reminds me - there's a boat that can sail directly upwind - I
think THAT one
can go faster than the wind too....)
