Power-plant scale Free Energy...

DMB writes: In this submission, we address the possibility of using tandem synchronous machines in a stabilized slipped-pole condition as a free energy prime mover for driving a third synchronous generator feeding the grid.
When I was an electrical engineering student in machines class, one of the students asked, "What happens when a synchronous machine slips a pole?" The answer was something like, "large torque pulsations occur, huge transients flow, and breakers trip..."
This was clearly an unstable slipped-pole condition whereas this document claims to investigate a stabilized slipped-pole condition. The questions arise "How do we achieve that, and what does it look like?"
The answer involves connecting two synchronous
machines by one solid shaft with the desired slip-angle appearing
between the spinning open-circuit voltages. Then the phases are
connected together A to A', B to B', and C to C' where the primed
open-circuit voltages of one machine lag the unprimed voltages of
the other by 60 degrees.
If interested parties
construct the phasor diagrams for current and voltage and calculate the
complex power for each machine, I believe you will find a net real
positive power (Pnet) for both machines in sum, and thus a net positive
driving torque, which can be used to drive the third generator feeding
and synchronized to the grid.

(User Info | Send a Message) | This slipped-pole free energy configuration is nothing new. Evidence shows Tesla knew about it and referred to it when he talked of the 4-quadrant operation of synchronous machines. A friend solidified the notion to me, and mentioned that the slip between the open-circuit voltages of the two solidly connected machines enables the conversion of torque-neutral VAR's in one machine into real driving power (P) in the other. Thanks for your patience...

(User Info | Send a Message) | I apoligize but I think I have been wasting your time with this submission. I was working without a scientific calulator and its astonishing how one can bend lines in phasor diagrams drawn freehand. Sorry. Humble pie squared.

(User Info | Send a Message) | Once again, I am Mr. Retraction. This idea, likely originally Tesla's, may have validity after all. The key is getting torque-neutral VARs in one machine to appear as real driving power (P) in the second tandem machine. When I originally mentioned a 60 degree lagging slip angle, I was choosing an arbitrary angle that seemed to work. Perhaps a better demonstration of principle is to have a lagging slip angle of 90 degrees. In this case, assuming a purely inductive (and equal) impedance for each of the two tandem synchronous machines (jwL), three resistive loads equal in magnitude to 2wL must be added, one for each phase, in series with the connected, 90 degree slip machines. In theory, this gives a phaser digram where one synchronous machine has purely driving power and the other has purely reactive power.
It remains to say what configuration might be optimal in a practical situation. But perhaps worth investigating.

(User Info | Send a Message) | Vlad, I am clearly barking up the wrong tree here. If you could see your way clear to, I ask that you delete the entire series of posts in this chain. Its just a distraction from the authentic free-energy work going on.

(User Info | Send a Message) | Something like this could definitely work. The key to making it work would be to add in a thermal engine, such as a nitinol engine or a sterling engine, in parallel with the generators so that the heat generated and wasted, due to the inefficiency of the generators, could be collected. If the wasted heat were to be put into a medium, such as a pool of water, several nitinol engines could be placed into the pool to scale up efficiency even more. Overunity could easily be achieved with this method.
While this is not Tesla's magnifying transmitter idea, it is practical, but only in a power-plant type setting. If you are wanting to free yourself, or your home, from the grid, this will not work - at least, not very well.
