Hello everybody, the sandjammer is ready to roll, so I'm thinking about the next vehicle. A sail-powered aircraft could be a balloon with a sail to catch more or less of the prevailing winds, but that is not very exciting.
The cinematic image is of course Jabba's barge from Star Wars, but were the sails more than just show? I'm prepared to go with science fantasy here -- how realistic are contragrav, jump drives, and stars arranged in a hexgrid? -- but I'd like to think about the laws of physics before I break them. * It is obvious that sails on a contragrav vehicle could be used to increase speed while running downwind. * It is equally clear that sailing directly into the wind is impossible. * Would it be possible to arrange the sails so there is some lateral propulsion? What do you think? Onno _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
