A pancake coil pick-up effect in which 500 W input lights up a bank of 9 500-W bulbs (maybe at 10-20% power), and they pulsate in and out in intensity, even though he is not changing the value of the input. And as he dropped the input down, the bulbs stayed at their same intensity, still pulsating.
A "cold fusion" flask with a plasma ark and huge volume of bubbles. The input/output on that were not measured. I'm guessing it probably is not demonstrating overunity, but it is interesting science.
A Tesla pancake coil, longitudinal transmission set-up.
A Kapagen coil array, explaining how it works.
A self-looped motor generator system (didn't get a full explanation).
 

  he is working on a number of exotic free energy technologies, including a Kapanadze variant kit that he says may be available in a couple of months for 200 Euros, which will produce 2 kW of power.

Tiens, à propos de Sterling, il attend toujours les résultats d'un certain Michael MacInnes sur youtube.
