Dear list, Is it possible for these buggies to tack upwind ?? I gather that there is always wind (even on calm days) at around 30 metres above the ground ?? Couldn't you use a Helium filled balloon kite type thingy or a small balloon to get your kite up here in the first place ?????

Hmmm... I'm not all that happy with this statement. There are fundamental differences. - The first is that fact that the kite is free to move through the air in order to increase apparent windspeed, independant of the speed (even direction...) of the craft. - The kite can be rigged so-as to pass all it's effort through a single point, effectively elliminating the capsizing moment of a sail (who's idea was it to put the sail on a big lever?) - Not fundamental, but important differences of the current technology include the severely limited amount of adjustment available to a kite while flying and the restrictions that weight considerations put on the design.

And buggies can achieve down wind speeds that sailors can't even imagine.
