[TCML] Re: Coils at Maker Faire

[Greg Leyh <lod@xxxxxxxxxxx>]

During a drive-by, the AC mains power and the tuning stay the same. 
What changes is the decrement of the secondary waveform.  Normally the 
decrement is a relatively smooth exponential decay.

When the roadster vehicle is within range and drawing power, the 
decrement becomes sharper and gains a distinctive beat note.  The beat 
note can become quite pronounced, even to the point where the decrement 
becomes non-monotonic... indicating that the vehicle can return energy 
to the coils as well as steal energy.   GL
