I love it. Fantastic demonstration. But I hope that you are working to
determine, refine and publish the overall efficiency of such an
application. I like to show off to my friends the fact that my TC can
brightly illuminate a 48" fluorescent tube at 10' from the source. But in
order to do that I am pulling 12 amps at 140 volts for the primary input.
Its an incredible waste of energy to say the least. That being said, I am
merely a hobbyist. I have zero formal training on the matter other than
having a HAM license. I would really like to see the numbers regarding
power output from the transmitting coil compared to the actual work being
done in HP or some other quantifiable measurement by the receiving device.

My two cents

Hi Brandon,
If you hadn't seen it yet, I have one paper on the circuit modeling and efficiencies:

We were able to get 22% at 5 meters without too much effort.  -Greg
