just a 3d model to show the bedini circuit... haven't built one yet in the real world so can't say how well it works...made this because i don't have any diodes to hand with which to try... The green wires are the power circuit that spins the rotor and then recharges the capacitor via the diode rectifier... the red wires form the control circuit that flips the switches(transistors in this case) on the power... i can't help thinking that for me it would be far easier to build with mechanical switching, using a commutator setup in place of the transistors as this would allow for much more intuitive fine tuning of the timing on the switches. Over unity? i doubt it, but guess anything's possible so still wouldn't mind trying just to see. You hear crazy science fiction writers talking about sucking energy out of the fourth dimension... maybe that, in a sense, is what happens in the Bedini setup...a simple case of twisting and squeezing moments in time... As I see it, for 99% of the time that the rotors' permanent magnet field is interacting with the coil, the circuit is set to charge, and any induced currents are rectified into the capacitor. That slab of time is then flipped around and injected sideways into the coil in an instant. The exact instant when the magnet is closest to the pole and therefore most influenced by the field generated there. All of the energy is released at once in a spike of power that's capable of exerting great pressure. Gears on a bike can spread the power over greater amounts of time as you pedal more with less torque, or inversely squeeze the power into less time by pedalling less with greater force. The electric field in the capacitor rather than trickling out slowly and weakly is unleashed with explosive force into the coil where it creates a very powerful magnetic field for just an instant of time. The magic is partly in the switches and timing. Current passing through a coil creates a magnetic field around it, which in turn creates an electric current in the coil opposing the flow that generated it. This back EMF acts against the power going into the coil from the capacitor. As the switches are thrown returning the system to charging mode, EMF from the coil finds itself unopposed by any current from the now discharged capacitor and flows unhindered as the magnetic field behind it collapses. The old collapsing field current cancels any Back EMF resulting from the new rotor field current in the coil, instead providing a temporary negative resistance and allowing the coil to transfer energy into the capacitor with more ease than might usually be expected. For a brief time it acts as a current in the coil, travelling in the opposite direction to that in the power cycle and creating a reversed magnetic field. This effectively drags an extra spike of power into the coil as it increases the fluctuating field density between the repelling coil and magnet. This means that for a brief time while the rotor magnet is in close proximity to the coil, any currents induced find far less resistance on their journey through the circuit, and at that same moment, as the magnet and coil are at their closest, the S pole on the coil vanishes and the N pole of the rotor magnet finds a N spike suddenly appearing beneath it for an instant, so accelerates away, adding more momentum to the rotor flywheel. Of course I may well be wrong about all of this, so welcome any comments on the subject that may enlighten me further... But please don't start banging on about thermodynamics and laws of physics... I know the arguments, i understand them, but i choose for now to ignore them. just in case. Where would society be without crazy people trying crazy things? we would still be sitting in a cave waiting for some lightning to start a fire for us. come on people, bang the rocks together... you never know what might happen... I came across the circuit diagram the other day in a zip file entitled "THE_TESLA_SWITCH_9_SEP_07.zip" and reproduce it here only to enable further discussion of its merits(or its lack of them...) The designs are of course out there, even if the truth isn't.
