You say the "aero numbers" will compete with the more expensive competitors. How will you know this? Are you going to spend the $2,500/hr in the wind tunnel? If so (and make the data know), sure I'll buy! I do think you can save *some* money by not using the absolute lightest stuff since most *here* know that aero trumps weight.

Also, if you discover that the torroidal rim ship is indeed fastest, how will you get around the patent?
