AS REPORTEDno primary record reached; this is what the reporting says
The evidence confirms that vacuum centrifuges operate within a vacuum environment to reduce frictional heating and convection compared to standard models, but it does not establish that they operate under entirely different fundamental physical principles.

In the centrifuges described above, the rotor spins in air or some other gas at atmospheric pressure. The gaseous friction on a spinning rotor increases at a relatively high rate so that the power required to drive the rotor also increases rapidly. As a result, the temperature of the rotor rises drastically, sometimes exceeding the boiling point of water. As the rotor surface near the periphery moves faster than near the axis, a thermal gradient or variation in temperature through the rotor wall is established along the radius with the periphery at a higher temperature than the axis. These small radial temperature gradients produce convection within the centrifuge, and these convection currents can cause remixing and disturb sed
