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.

But geez, there has to be a way to pulse a mosfet with the FG on the gate and the feed supply through the drain/source without having to use such mosfet drivers. I mean why is there not a way with a few resistors and a diode somewhere. Maybe using a dual coil toroidal 1:1

There is a way but it is not the most efficient and you must use complementary transistors as well as a signal generator that can drive the MOSFETs into saturation.  For most power MOSFETs, 5V on the gate is not enough to fully open them.
What is the maximum amplitude of your signal generator?  Is it bipolar (reversing polarity) or unipolar (pulsating DC) ?

Just about to leave the office for home. My HP 8116A FG does it all up to 50mhz, 16vdc (mA) and any width before 1MHz and at 50% duty after 1MHz. I can even switch the polarities and can do sine, triangle and square waves.

The manual for it is here http://purco.qc.ca/ftp/Equipment%20Manuals/
Just click on the hp-8116a.pdf

+16V is certainly able to directly drive one power MOSFET gate in the complementary Half-Bridge.
-16V would be needed to drive the other half (-10V would probably be sufficient)

Before reading the HP 8116 manual, I will not know if the output is:
-16V to +16V
0V to +16V
-8V to +8V

It is -8V to +8V under load, so maybe it can drive complementary power MOSFET's directly (without a driver).
Just make sure they are complementary transistors (N-Channel and P-channel)

I am still waiting for those parts to arrive. There was one item (HV caps) back ordered so they held back shipping out what they had on hand. What a piss off. So I have to wait and wait, but meanwhile I am trying with the standard circuit that is just going no where.

But geez, there has to be a way to pulse a mosfet with the FG on the gate and the feed supply through the drain/source without having to use such mosfet drivers. I mean why is there not a way with a few resistors and a diode somewhere. Maybe using a dual coil toroidal 1:1 transformer between the FG and the gate. I don,t know but you would think since so many years guys would have figured it out by now.

I want to take out my  yoke again and re-do some of my previous experiments with some changes. I had one great effect that I would like to catch on video.

Anyways, I can only see great success for all in this pivotal year of 2012, in a just and perfect manner.

My 2 cents

perhaps this can help

good luck at all
