Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

ebay sell programmable DDS signal generators for about $20. They work from Hz to about 8 Mhz.   If you buffer this with a single stage RF tranny then drive into Push Push IRF540's  using wideband baluns you should be able to pick the 2nd or 3rd  harmonic as 16 Mhz or 24 Mhz which is about the top end of driving cheap IRF's fets.


At low end < 10 Mhz it will push up to 40 watts using 24v supply on a pair of fets. Current will be around 3 amps.  Over 20 Mhz might squeeze 8-10 watts out.   For higher frequencies and more power the cost is going to run in to hundreds of dollars for a better solution.  If you strike lucky you might find some NMR experiments in these low frequency range. Whatever it is certainly going to be better than a cheap bench signal generator going to 1 Mhz with 1mW signal o/p.  Nothing going to happen at low power levels.
Dear Bolt,

Many thanks for your input, would you be able to "Draw up" your circuit for me? I really think we should be able to see NMR in the 100's of Khz by tailoring the field strength. But at the moment I just can't apply enough power to the "Resonance coil"

Cheers Grum.

BTW. Did you mean Push Pull? I Googled push push, nothing turned up!

P = A2/(6.28*f*L)
So,   8 times 0.707 equals 5.657, squared 32, divided by 40 equals 0.8. Divided by 1099000 equals 0.07 micro henry, well near enough?
Are you sure about your value of A(RMS) = (8V*0.707=5.657V) ?   Take a look at the attachment below...
Also  0.8 / 1099000 = 0.000000728 and that means 728nH  (not 0.07μH)

Anyway, the reactance of a 728nH coil at @175kHz is 0.8Ω  (+ any DC resistance of the coil) and you would be hard pressed for an amplifier that can handle a load around ~1Ω.
Most of the commercial amplifiers are designed for 50Ω loads.  See here why this matters.

The relevant equation for the impedance of your coil at a given frequency is:
Z = 6.28*L*f + RDC
where, Z: AC impedance of the coil in Ohms, L: inductance in Henrys, f: frequency in Hertz, RDC: The DC resistance of the coil in Ohms

Also, the previous equation amended to account for RDC is:
L = (A2 – P*RDC) / (6.28*P*f)

The main thing is the working device, then we can keep talking about theory and working principals, while lighting our houses, and running our cars on our homemade devices.

In the meantime we should keep deep meditating until we can see in our minds clearly what's hidden in the tin can that provides the orange cable with 24 amps AC out of the blue. 8)

Could be something simple ...

If I see any more pics of that bloody tin can, I'll start dreaming about it!  ;D
