The Composite Force of the  Radiometer

L. Thompson

I call the radiometer force a composite force as it includes the deceleration of the rarefied gas molecules in transferring molecular momentum to give the net acceleration of the radiometer vanes. After the transfer of molecular momentum the rarefied gas molecules become  a dead weight until re-energized. My testing is in a partial vacuum of 100 to 300 microns. I use a 60w halogen light focused on various weight aluminum strips with carbon black on one side. The strips were holed to freely move on a horizontal rod.

With the weightier strips, after a little back and forth movement, the strips would bind on the rod. Yet I observed a 0.002 gm, 1 cm strip, holed on one end to hang on the rod, that the strip moved first with agitation and then energetically around and along the rod.  Though a small mass,  I found the centrifugal motion could  have a directional movement.  (Note: this tending to confirm Cooks' original observations.  http://en.wikipedia.org/wiki/Crookes_radiometer , 2nd paragraph.)

With limited equipment I do not take the testing further. As a proposal for additional testing I would use a test "apparatus" with the "surfaces"  fixed to a light weight rod. The rod suspended with fine wires. This test would determine if the net force could be directed to propel such a light weight "apparatus" forward. 

The forward movement would be limited by the wire mounting. Yet I feel the confirmation of a forward movement could open the possibility the application of a net force might cause the acceleration of a body by using the inertia of a body itself (rather than the earth) as the "accelerative base". 

A fuller study of the radiometer force could include the energizing of the gas molecules and the deceleration phase of the  gas molecules to give the resulting macro vane acceleration.  It would explore the implied high molecular velocities across the vane surfaces. It would explore why there is little offsetting back force in the net macro vane acceleration.

I feel the radiometer composite net force, using vane inertia as the base, could be capturing most of the molecular momentum to reach, in a well balance radiometer, 2000 to 3000 rpm.

In my other paper (Note D)  http://accelerativeprocess.com , I propose a force with similar properties as the radiometer force could be taking place in the spiral galaxies.
