Hey,
I've been trying to replicate Romeros selfrunning wheel for some time now. I havn't got it selfrunning obviously (Romero released further information about how he did it), but what I have might share similarities to what ufo is presenting.
Let me explain: I am pulsing what originally is a driving coil in my setup with a NPN transistor with the help of a hall sensor. The hall sensor is placed close to the coil and seems to pick up the coils magnetic field resulting in fast oscillation. At this time my input drops from around 1A to 100mA (15V in) but the coils voltage is 60V peak to peak at a frequency of about 200kHz (well above audible range) measured with a scope!
Now with the two diodes method I've got my motor running very efficiently. Maybe just a little more than 1 watt input. I am using two fast switching Schottky diodes to collect the oscillation output. I connected the diodes like shown in this thread (thanks to ufopolitics). I am feeding the output to a second driving coil which is creating one spike to just overcome the drag. The second coil is also catching some of the oscillations from the first coil.
Happy with the result. I've made a short video.
Thanks ufo for a possible explanation and especially your free sharing, it is clear now that our minds keep blocking us from what's possible. We are trapped on the hot side and in our conventional way of thinking. Know-it-all attitude is bull****. People are getting demotivated by this kind of crap. Everybody can contribute and everyone is welcome. People should work together and show respect for each other. We would go well beyond more rapidly.
