Truth be told, I don't really know what I'm suggesting, if anything. As I said "fun with numbers". It could be a coincidence, or not. However, if it's not, then the implication would indeed appear to be that the field distortion that produces the thrust is related to the disturbance of space time accompanying the Earth's motion (frame dragging?) >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 > >-----Original Message----- >From: mix...@bigpond.com [mailto:mix...@bigpond.com] >Sent: Wednesday, April 29, 2015 11:25 PM >To: vortex-l@eskimo.com >Subject: EXTERNAL: Re: [Vo]:more on EM drive > >In reply to Axil Axil's message of Wed, 29 Apr 2015 21:41:19 -0400: >Hi, >[snip] >>http://www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive/ > >The geometric mean of the Earth's rotation speed and it speed around the Sun is >3714 m/s. > >If you divide 2.5 kW by 720 mN, you get a speed of 3472 m/s, which is 93.5% of >the former.
