Free Solid State/mechanical energy

I made the calculations Tesla suggests in patent 512340 and I found something unexpected.
I recommend you all do the same and compare the energy between the two coils.
Same voltage, same length of wire, different results.

Cool barbosi!

Post what you did.  I'll try to look at it and make the same calculations, unfortunately I'm a little tired tonight - might do it tomorrow.

Patent 593,138 Electric Transformer - November 2, 1897

Cone-shaped secondaries to focus the impulses, these brought white-fire discharges, an aetheric nature, a cooling effect. The secondary was wound over the cone and then the primary  at its base. Both the primary and secondary are grounded.  Definitely these were very safe but also as these new "Impulse Transformers" greatly magnified power supplied to them, also the radiant electric effects  were equally magnified.

After re-reading patent 593,138 it occurs to me that really the whole point of this was to see induction coils in a whole new light.  Typically we think of an induction coil like in standard transformers - magnetically linking two circuits by the basic (V1/V2 = N1/N2) ratio. 

These coils do not operate like that.  Since they are based on the velocity of the currents inside them, they produce a small voltage between each winding.  When you add up all the windings you get a pretty large voltage.  So each winding of the coil is like a tiny charged capacitor.  When you add up all the capacitors in series, you get a large voltage between the terminals.  Very cool stuff.

i just built one of the bifilar coils to erfinders spec.
in standard form i get a 20 v pk to pk back emf spike
in  the bifilar form i get 40 v pk to pk.
the magnetic field seems to be the same for each type.
the bifilar has both primary and secondary wound in bifilar form.
the magnetic field can be just felt at about 3mm from the iron core.
