The theory of vacuum-mechanical energy conversion is subject of . The concrete planning of a verification experiment is described here.
For the fundamentals in , a point charge is placed above a special rotor. In the geometry there, a torque onto the axis below 10^-7 Nm is generated. This does not surmount the friction of the bearings carrying the rotor. So the geometry was optimized by the following calculations: An extended field source was subdivided into elements of electric charge of which image-charges on the grounded rotor blades have been determined. The electric field of all charges and image-charges and the forces between them were calculated (see ). Finally the results were confirmed by ANSYS .
A disc as field source and a rotor of 60 cm diameter, supplied with voltage of U=10 kV, can create a torque of 4*10^-5Nm. This should surmount friction as the estimation shows: If the rotor has m=0.05kg, its force onto the bearing is G=mg=0.5N. A coefficient of friction of µ=0.2 and a typical toe-bearing (observed tip radius r<100µm) then cause a torque of friction of M=µ*G*r<10^-5 Nm.
Possibilities for further increase of the torque:
The torque follows the proportionalities M~U^2 (U=voltage) and M~R^2 (R=rotor-diameter), if the geometry is adapted.
Vacuum allows to enhance the voltage. Air has an electrical breaktrough of 10kV/cm, but vacuum has 5000kV/cm. => Enhancement possible up to M_vac=500^2*M_air=10Nm even with our small setup.
Experimental pre-tests indicate that inaccuracies of the symmetry critically influence the rotation.
A lightweight rotor with low moment of inertia enhances the angular acceleration and makes the measurement easier.

Thank to Dr. W. G. Kürten-Ihlenfeld at PTB for allowing me to use his ANSYS.
These are results of planning an experiment to convert vacuum-energy into mechanical energy, based on computer simulations and on pre-tests with a rotor in an electrical field.

RE: “These are results of planning an experiment to convert vacuum-energy into mechanical energy, based on computer simulations and on pre-tests with a rotor in an electrical field.”
1. What are ‘pre-tests’ ?
2. Is this yet another attempt at a perpetuum mobile/perpetual machine?
