Practical Guige to Free Energy Devices

created by the signal bouncing off the end of the wire and being reflected back. At frequencies other than the
resonant frequency, this results in a constantly changing set of many different waves travelling in both directions
and at different intensities (what could reasonably be described as a total mess). When the resonant frequency is
fed to the coil, then all of that mess disappears and just one waveform remains, and at any point along the wire,
that waveform appears to be stationary although, of course, it is not actually stationary, just the effect of the peaks
always occurring at exactly the same spot and the troughs occurring at exactly the same spot, making successive
waves look exactly the same as the previous one.
This feature has one very practical aspect, namely that if you run the same wire away from the coil turns to
connect to whatever the next circuit component happens to be, then the wave inside the wire will not bounce back
at the end of the coil turns but will continue on to the end of the wire before bouncing back. So, the connecting
wire length has to be included when reckoning the wire length in the turns of the coil. On the other hand, if the
wire in the coil turns is terminated at the ends of the coil and wire of a very different diameter is used for
connecting to the next component in the circuit, then the signal inside the wire will bounce back from the sudden
change in wire diameter and so the connecting wire length will not be part of the wire length in the turns of the
coil. This is an important feature if you are aiming for an exact 4:1 wire length ratio (and 4:1 wire weight) between
the Tesla Coil windings in order to impose an automatic resonance between the two windings.
It should be noted that PVC (especially non-white PVC) has a very restrictive effect on high frequency coils. At
low frequencies, PVC is ok, but it drags down the coil performance as the frequency rises, lowering the “Q” (for
“Quality”) factor of the coil. Using acrylic instead of PVC overcomes this. Alternatively, coating the PVC with a
high-voltage insulating material such as shellac or one of the proprietary coating agents, will improve matters
considerably. The ideal, of course, is to have no former at all and have the coil standing unaided because of it’s
own strength.
Making a Solid-state Tesla Coil
As some readers may feel that there is some "black magic" about the neon-driver circuit used by Don to drive the
Tesla Coil section of his circuitry and that if a suitable unit could not be purchased then the circuit could not be
reproduced or tested, it seems reasonable to show how it operates and how it can be constructed from scratch:
The circuit itself is made up of an oscillator to convert the 12-volt DC supply into a pulsating current which is then
stepped up to a high voltage by a transformer. Here is a circuit which has been used for this:
The supply for the 555 timer chip is protected against spikes and dips by the resistor "R" and the capacitor "C".
The 555 timer chip acts as an oscillator or "clock" whose speed is governed by the two 10K resistors feeding the
440 nF capacitor. The step-up transformer is an ordinary car coil and the drive power to it is boosted by the
IRF9130 FET transistor which is driven by the 555 chip output coming from it's pin 3.
The output from the (Ford Model T) car coil is rectified by the diode, which needs to have a very high voltage
rating as the voltage at this point is now very high. The rectified voltage pulses are stored in a very high-voltage
