Well, these technologies that are electromagnetic field propulsion technologies result in what we call a mass cancellation effect, where the actual weight of something is reduced and it can float around and move as if it has no weight at all, like it's in an anti gravity system, which it is. Now, the other thing that's interesting the CAT scans on the interior don't show any. Moving parts or things that would look as an energy source. There's no radioactivity. There's no oil. There's no jet rockets. There's nothing. So, this is truly an electromagnetic anti gravity field device.
