Yo..just a note... on one of the essential ingredients for building anti-gravity craft. An essential one which was previously unavailable. Too expensive, too unreliable, difficult to apply, difficult to find.
That has changed.
The number I heard, IIRC, was that a RPM of about 50k was required on a spinning high mass fluid, in order to build up a gradient in the gravitational fields, for a Vimana to take off from the surface.
Well, now you can get ultra reliable 50k+ rpm 1600 watt/2hp motors for about $50.
Those are the DYSON vacuum cleaner motors that are all over eBay.
The latest motor is 1600 watts, or just over 2 horsepower ..and runs at a stable 110,000 rpm!!!
It took Dyson 15 years to get there. This motor is about $50-60US, NEW, on eBay.
Now you can find a way to...... put them in space.
The critical stuff is now easy to get a hold of, so get at it....the requisite motor/engine is now out there in the 100's of thousands of examples... so figure out how to apply it.
PS: Since aetheric conditions of spin/mass will be occurring at these high speeds, the motor will also be applicable in over-unity experiments and similar efforts.
