Here it is: (Message from Frank Howard, used with permission) If you swing a mass on a string around in a circle, the mass is pulled outward by centrifugal force. The swinging of the mass in a circle caused an angular acceleration on the mass pulling it outward. The angular acceleration [feet/second squared] is equal to angular velocity [radians/second] squared times the radius [ft.] of swing. The acceleration force [lb.] outward equals the mass [lb.sec.sq./ft.] times the angular acceleration [ft./sec.sq.]. If the radius is increased, the angular force is increased in direct proportion. Consider a stationary gear with another gear with the same diameter rotating around it. Place a mass at the outer side of the rotating gear. The locus of the mass as it rotates has a greater radius on one side than the other. It can be plotted as x=acos(A)-1)sin(A) and y=sin(A) where A equals the angle of rotation. If four gears are place 90 degrees apart, and the forces from the masses are summed, a constant force with an amplitude of 2 is produced. The mechanisms could be driven by electric motors and constant propulsion force and acceleration could be produced. I have been talking to one of my directors about using small modules powered by these centrifugal drives to rescue satellites from falling out of orbit. The centrifugal drive modules could be stored in an small unmanned space station covered with solar cells. NASA is too involved in organizational political wars and struggle for survival to think about these things. A more efficient process not requiring moving machinery would be to chill down superconductive material with cryogenics. Resistance is directly proportional to temperature. Current is inversely proportional to resistance, so the super conductor could produce a strong magnetic field. Atomic particles such a protons could be accelerated with a positive charge from the super conductor with each rotation though a curved pipe line. The mass of the protons would increase with velocity. m=mo/(1-v^2/c^2)^.5 where: m=mass of traveling object mo=mass of still object v=velocity of mass c=velocity of light as v approached c, m approaches infinity. The particles could be sent down a path with a large radius of curvature providing acceleration. Space vehicle could be created that would be completely silent. Action reaction vehicles could be used to overcome gravity. That was some stuff I was dreaming about. I have probably left you bored stiff. Most of my work at NASA has been on cryogenics. NASA put some of it is on the net. Frank Howard (The man at NASA who sent me this)
