I made a few days ago an energy transmission experiment for one of my friends, with the miniDRSSTC. The input voltage is cranked up slowly to 312 VDC, with a very low freq pulse (bolt lightning appearence). Here is the movie:

I watched the film, I think lighting neons near coil is pretty common actually.
Well, and i also did some interesting experiments recently. Small 1W bulb and lamp from saver bulb are energized perpetually.
This ''receiver'' is actually secondary of mini TC used as resonator, that is actually not resonant at all (frequency is about 1,5mhz) and it is picking power from 2Mhz micro SSTC (you've probably seen it) 1 meter away. That SSTC actually lights neon bulbs in hand maybe 7-8cm away max, so this is very interesting. Non-resonant secondary makes almost the same amount of power to be transmitted to 14 times larger distance. Im confused about how it really helps here,
Neon is connected to ground wire of ''receiver'' and small 3V bulb is using 7 turns wound around secondary to couple with it magnetically.
If my hand or any grounded object approaches it dims the bulb. Even more interesting is that neither coil nor ''receiver'' is not grounded, actually it suffocates the transfer if I ground them.
If we call it tesla's wireless energy transfer we may, but with such losses charging a cell phone would take long. It rather shows principle than having some use.
I dont know exact efficiency but its obivously very small, im putting about 40 watts in coil, say half is dissipated (it dissipates a lot of heat on mosfets and secndary, EM loses, etc) so say 20 W is electric field, and I pick up maybe 2W from that. so say its not above 10%.
