Radiant power from Solid State Hairpin circuit

I made an advanced solid state hairpin circuit producing radiant power.


It is based on a high side switched coil (L1) producing a negative back EMF impulse.

This impulse is injected into a series resonant bifilar pancake coil (L2).

The – BEMF impulse, replaces the sparkgap.


This L2 coil also has a positive DC offset, charged by the – back EMF.

The L2 coil equals the stout bars in the hairpin circuit.


L2 is loose coupled (4,5cm) to L3 (bigger bifilar pancake coil) that is parallel resonant. So both L2 and L3 resonate on the same frequency. L2 is series resonant (low impedance, so impulse can pass to positive of power suppy, giving the L2 a kick) and L3 is parallel resonant (high impedance).


L3 is parallel loaded with a 28W 230V light bulb, that lights up brightly.

The current and voltage of L3 are in phase. This is rather unique, as it is 4,5 cm distanced from the series resonant L2 (current and voltage 90 degrees out of phase). Radiant power is produced.

Hey Evostars, thank you for sharing your schematic I looking forward to watching your video when it is released.

Hey Evostars Great work,thanks for sharing. I was following your videos before, but was not aware that you are member of the forum, as you did not post a lot. What do you think about the possibility to couple the three coils at certain distance, if it would give the same input power reduction as in the former test? Regards Vidura.

Hi Evostars,

Excellent work, thanks!

This paper might be of interest:


Happy Easter...

  • In brief, a possible take-away: Power [p(t)] {eqn 8} and instantaneous Energy [w(t)] {eqn 9} are independant for a switched circuit (?).
  • "From basic physics, we know that power is the time derivative of energy. Consequently, there is no power (consumed or stored/restored) if energy does not change with time. Therefore, the instantaneous energy can be computed from the integral of the instantaneous power" ... "Equations (8) and (9) form a set of linearly independent equations" ... "A proof that (8) and (9) are linearly independent functions is given in the Appendix. Equation (9) can be seen mathematically as a moment of (8). However, this paper is centered in physics rather than in math." 

{this is an IEEE paper - therefore excess energy "does not, can not" exist - so, say it differently! "linearly independant functions?"} cool

Addendum Note: See Section "E." (starts on page 2109) in the above paper...

Thank you Evostars for yet another masterpiece of experimentation, invention, superb presentation and documentation. Your Radiant Energy/Power series is developing into a classic.Cant wait for your next episode.

More power to the dielectric!

Best regards

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
