Yes, this would be a good next step in exploring this.  I think the oscillator will become and function
as an RF mixer too. 
Provided the second crystal is willing to oscillate too, in parallel with the 13.56 MHz,   that is...   
You may happen to have crystals with say a few MHz less frequency than 13.56 MHz.
And for a start, just use a single 13.56 MHz and another single crystal only, say with having a lower frequency.

TK,  Gyula,

nice experiment, and i agree with Gyula that the oscillator will become a mixer too.

Using the normal 13.56Mhz crystal in screenshot 1 
Adding a 12Mhz crystal parallel to the first one, see screenshot 2.

I had to increase the input current to around 50mA before the 2th crystal would start.
Will try some other frequencies later tonight.


These extra peaks goes for all the harmonics too, so the whole spectrum becomes a littered with spikes

I ran my one wire energy transmission experiment again using just a 13.6MHz sine wave signal from a function generator and it worked.  The results were not as good as using the crystal oscillator however. 

Gyula-- I mentioned your name in the video and I apologize if I mispronounced it.  I did some research on mutual inductance and you are right about how it relates to what I am doing in these multiple coil experiments. 

erfandl---I tried the multiple crystal experiment on my oscillator circuit briefly.  I did not see any significant difference visually but perhaps there was a difference in the power draw.  It was just a quick test and I didn't do any measuring.

TK --- Your idea about mixing the frequencies was interesting.  I'm wondering if I can inject a signal into my 13.56MHz crystal oscillator output using my function generator.  If we got lucky there might be a compounding wave happen like a freak wave in the ocean.  Just guessing.

Here is the video of my 'hallway' one wire experiment using a function generator:

PS--Here is how a freak wave forms in the ocean.  Maybe we can do this electronically ?

Lidmotor, 

nice idea to inject an extra signal with the FG into the Xtal oscillator.
This speeds up the process of trying multiple different crystals.

Using a 100nF ceramic cap to inject the FG signal into the base of the resistor.
4Vpp sine wave ranging from 350Khz to 26Mhz creates many different patterns of signals on the SA.

itsu---  Thanks for trying that experiment of injecting a separate signal.  I was hoping for a massive tall spike to show up when a second wave showed up at just the right frequency. It doesn't look like that happens.  Perhaps if there were multiple frequencies but that is hard to figure out where to even start with that experiment. 
  Thanks again for the effort.

Lidmotor, 

i see what you mean, but there are so many tests done in the past and now involving 2 signals being mixed
that if there is a special combination that produces something like an electronic freak wave it would have
been found by now, i think.

But you never know so there are still some parameters to meet i think like should those 2 (or more) signals
need to have the exact same amplitude (which is hard to do with a FG and X-tal osc.) and should the difference
in frequency be a few Hertz or kiloHertz etc.
