    Hi Duncan
    I love this thread and all that you have presented so far.
    However the last post bothers me a bit. I worked for a large machine manufacturer designing and troubleshooting the electrical systems. I have seen many a motor failures.
    On every occasion it could be broken down to a few different things. Most common was that the installer would supply to small of a supply line to handle the amps needed to avoid a voltage drop for the lengh of wire run needed. Second would be a bad connection somewhere within the system also causing high amperage and voltage drop. Or you could have a simple situation of overloading the motor again causing high amperage and voltage drop. Of coarse all of these situations create heat and something burnt out. A properly set up system will usually run for years.
    This is my own observation, but maybe I still am not understanding the situation. Are you saying that we need to create a situation of high amperage and low voltage?
    I stand ready for correction.

      Duncan,

      Simple question : do you know and can explain what is radiant energy ?

      Zardox : can you easily explain why the subsequent run of motor not so long time after turning it off consume much less input power ? It looks like electric motor has a "cold" and "heated" state exactly like an engine.

          Hi Boguslaw ... luckily "Radient energy" is in the lexicon's and so there is no need for me to explain anything .. however here's a very simplified description which should explain it for you with out to much stress on the english
          What is radiant energy
          kind regards

              (so this Zardox is why I was pointing to very high circulating currents)

              For those with a RF or electronics background this then is effectively an "acceptor circuit"

                Good afternoon,
                This is a picture of a motor I converted to a wind turbine generator. It has the original 3 phase winding and a new rotor. The rotor was machined to a double octagon and 16 2" x 2" x 1/2" magnets epoxied on. The whole rotor was then wound with fiberglass filament and epoxy. The original was 15 hp and at the slow speed the turbine ran max output was about 1800 watts. I spun the rotor up to 800 rpm when it was new just to see if it would hold together before sticking it into the air. I don't know if it will withstand 1750 synchronous speed or not. It might be a receptor for reactive power ??

                  OK , I am beginning to get a picture. At least in theory anyway.

                    Nice job Garry ... seems a shame to destroy it before it ever gets to do the job you made it for ... or is that the welding upside down up a pole thing?
                    It which case ....

                      Here is part of my theory.....This modulated high frequency current, which you depicted Duncan, (if modulation is pure sinewave or other periodical but not sharply changing) is what I believe exactly so called "cold electricity". For all resistive loads it is like a slow frequency current but indeed it is HF having skin effect so it's more or less harmless. For any other loads it depends on load , because there appear a slower frequencies as an effect of intermodulation. Basically it can be converted to our 50/60Hz by using a filter.

                        Here is one of the rotoverter group .. demonstrating the reactive current conversion.

                            Well,Duncan if I'm right , for example about "cold electricity" then as you see there is nothing spectacular about it : radio frequency of even Mhz range currents can be produced and modulated and Tesla even mentioned no effect above 10khz afaik. Now compare that to all that mystery layered above simple HF modulated to low frequency current. Sure, I can be wrong , because there may be more then one effect included into the total "cold electricity" statement, like the "frozen wires effect" and so on.... The main trouble is the one statement was used by many inventors describing different devices.

                            Without clearing the mystery part we can talk a lot about magic stories....

                              Duncan, this genny rode a pole for 6 years. It is expendable. The new one is a geared grid tied 10KW over driven induction motor.

                                Gary,
                                Epoxy is stronger than you know. I have a SSG with a 6" rotor. Two 7/8" thick pieces of particle board with a hard drive rotor sandwiched between them. Six 1x2x1/2 magnets epoxied on the outside of the boards. After about a year of running, I wrapped some nylon reinforced packing tape around the rotor. Has been running for over 2 years at around 2500 rpm. I would say your genny will hold up just fine.
