I believe Woopy is posting over at OU. Not sure of the thread though and i'm not a member there.
The Brovin/Kacher is a Tesla coil type setup, very much like the Slayer Exciter. The Slayer was created by Slayer007 of Energetic Forum, who posts on YouTube as GBluer.
Instead of a thin tall Secondary, it's short and fat. People such as Eric Dollard and in fact Tesla himself, used to use much larger diameter coils than the popular perceived Tesla tower setup. An interesting aside, being that the coils seen in Tesla's famous double exposure photos at Colorado Springs, are actually collector/repeater coils and not the main device ! If you look at the main device in such pictures, it's much more like the Kacher design.
i'll dig up a pic and attach.
A Kacher normally uses fewer turns than a regular thin tower, of larger gauge wire.
Here's a short vid that explains the Kacher:
http://www.youtube.com/watch?v=xMiNnHzFsRQHow the motor runs is relatively simple, if used to Slayer Exciters. That's not to belittle Woopy's success - marvellous development.
With an AV plug (Avramenko twin diodes), you connect the AV plug to the load, an LED or a motor or something else. it half wave rectifies the incoming AC and often is enough to run something. However, these devices work far far better if a ground is connected to one of the legs on the load side. What Woopy has there, are two more diodes. You can create a virtual ground with your own body, which, is why many experimenters hold an LED as RF field detector (Lidmotor, Jonnydavro, GBluer, myself etc). The virtual Ground can be a large heatsink or a physical Ground connection. Dr. Stiffler used heatsinks and matched metal masses to great effect in his related SEC exciter circuits.
The pickup doesn't need a connection at all.
In motor run experiments, most notably for myself with wireless electric flight, you can wind a collector coil with a few turns of wire, remote from the circuit. A full bridge rectifier of 1N4148 diodes and a small electrolytic cap will allow up to about 1/2A and 80 volts to pass (depending on strength of field and capacitor rating). Faster diodes with good HV characteristics are even better. Range of running in terms of RF field distance, can be up to a few inches typically...improving with frequency matching and power output of the tower. In practical terms, 32V will give more wireless range than 1.5V, the tradeoff usually being transistor heat and why 12V systems are a common setup.
