Robin, Ok, but I would assume the "thrust" vector is constant relative to the device not related to the direction of orbit..or are you suggesting the force is limited to exploiting ambient gravitational field [eliminating applications for extra-solar propulsion? Fran

If you divide 2.5 kW by 720 mN, you get a speed of 3472 m/s, which is 93.5% of the former. (fun with numbers ;) Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
