Hi All,

I am very glad to see the discussion moving on to the science here. Ben has hit the nail on the HEAD! When you look at Teal's commutator on page 3 of the first patent, you can see that he was using very short duration pulses. I suggest in the section of my DVD where I am talking about what features must be present in the solenoid design to get high torque, that Teal used a short, sharp current pulse of a few milliseconds, and that the ampere-turns in the coil equals magnetic field strength. A high energy thrust is transfered to the movable plunger when the crank shaft is in the middle of the stroke.

Ben's idea of applying a capacitor discharge to the solenoid at this point simply maximizes this process. Now, the magnetic thrust vectors applied to the crank are approaching "explosion" velocities, and the power goes way up. And you can still recover most of the electrical input. So the motor can create huge amounts of mechanical energy for the "differential loss" between the amount of electrical energy applied minus the amount of electrical energy recovered. In systems properly designed, this "differential loss" will be under 50 watts per mechanical horse-power produced.

Congratulations Ben!

I will be posting some new drawings on a back page of my website in the next day or so that will show some very simple rotor designs that can produce high torque. The "S" rotor is difficult to machine and in recent tests does not perform better than simple cross bars. More on this soon.

Also, Teal's patents are posted on my Bob Teal page as .pdf files for easy viewing and downloading.

Great work, everybody!

Peter
