I tried to rebiuld a Don Smith Device

Dear Forest
I also have the same question and i have read many opinions on this. I started to believe that the real resonance is not what we have been taught in school. At least not the OU or Lenzless resonance. For me, real resonance occurs when the resonant frequency has a harmonic that matches with the length of the wire so to make it oscillate at it's own frequency. If that happens to both primary and secondary, then we talk about Lenz law bending. To take an idea take a look at my latest approach in Radu Morisan oscillator circuit here...

If this wire length/frequency relation is the same to both primary and secondary, the oscillation is constructive and not destructive which is the case in Lenz law.

Resonance between L1 and L2 can take place at Wavelegth, 1/2 Wavelength and 1/4 Wavelength.

For best loss less resonant effect keep frequency a bit low. About 25Khz.

Keep self inductance very high compared to capacitance of the L1 and L2 both. Your radiating losses shall be minimised to 5% if you follow the above.

Think think.

DON SMITH WAS NOT A FAKE

here is the proof :

this is just half wave or full wave rectification,   this in it self does not prove he was not a fake, this is not free energy, 
if you dont understand ,  put a tin foil on a neon lamp or just an energy saving lamp, and connect a half or full wave rectifier and a caoacitor to the output and watch the voltage rise in the capacitor.
