Rosemary Ainslie circuit demonstration on Saturday March 12th 2011

[Rosemary Ainslie]

Rosemary, I've just been going through your blog-Report - you really should do something about the images there, though 'click-able', they don't expand much if at all, and are almost unreadable!  But I made a discovery - despite all your talk of negative voltages on the gate from the get-go, I always took this to mean zero-volts! Rank-amateur and sad but true, it also kinda explains why I had a negative result the first time round - I was using a pulse-generator, 0->5v range, not the the 555 circuit.

Do you have a link to where someone could buy the heater element you used?  The company "Specific Heat" you list in the report doesn't google anything relevant.

Sprocket - this is beginning to sound promising.  Yes. I can definitely pm you on this.  But PLEASE.  There is absolutely NO requirement for a precise component EVER.  I need to make this very clear.  I'm not sure of the cost but those are standard immersion heaters.  What it shows is that it works very well.  Plus/minus 10 Ohms.  Guys - for anyone wanting to experiment on this or aspects of this test - it is absolutely NOT frequency dependent and nor is it component dependent. I KNOW that this can be shown on just about any variation and variety.  Look even at the configuration that Mags has shown.  All that is needed - as I see it - is that there is the generation of BEMF - or - maybe - FEMF as Mags calls it.  BUT.  To generate that amazing burst oscillation - then I THINK you all that is needed are those mosfets in parallel and some kind of negative triggering.  That's it.  I would be really sorry to find that anyone gets ensnarled again in attempting a precise replication.  It's not needed.  Look at all the varieties that I've shown.  And I've only given a fraction of what our data shows.  And you guys are skilled.  You could very easily take this to some kind of application.  That would be so nice.  Just to tempt you.  I think you could unplug your hot water cylinders with between 6 and 8 of those batteries.  I'm reasonably certain that we were dissipating in excess of 200 watts and that with just 4 batteries.  If you do this and if you manage it - then let us all know.  It would be most enouraging.

Kindest regards,
Rosemary

@Sprocket . As you have worked out for yourself , a simple function generator without a voltage offset control will only give a square wave out put that toggles between a positive value [say 5 volts] and zero . The 555 timer circuit is just the same except that the positive part of the square wave is at a higher voltage , approaching the voltage of the battery supplying the 555 circuit . Rosemarys function generator has a voltage offset control . What this does in effect is move the zero line of the voltage graph up the page , so the pulses are alternately positive and negative . note that depending on the control setting these pos and neg voltages are not necessarily equal . In other words you can move that zero line as far up or down as desired . Note that In its published form the 555 timer can NOT give negative pulses . I have a circuit in my head that could enable it to do so , but I do not know how to put it on the computer .The simple battery and pot circuit I describe above simply keeps the gate at a constant negative voltage .

Hey Woopy

In teslas igniter pat, he uses a very low ohm primary of another transformer let say, in series with your switch across the cap.

The switch has 2 ON functions.   

1 When closed, the large inductor is put directly across the source, so the freewheeling builds much quicker and stronger. Now when the switch opens, the inductor charges the cap really high, because it takes a lot to bring the inductors freewheeling to a halt, because its spinning so fast. ;]
Like a bullet from a gun, if I throw the bullet at you, you might just laugh at me, but from a gun, a lot of speed and speed is power. ;]

2  When the switch closes, it doesnt just short out the charge in the cap, it dumps it into the low ohm primary of the transformer, while the source is getting the inductor going.  Get it?  Tesla was pure genius. So efficient in all ways.

So instead of charging the cap as you are, and just sorting it out to discharge or sending it elsewhere via another way, the one switch does it all.  If you have another microwave transformer or an automotive spark coil, you can use its primary in series with the switch
and keep the first transformer you have been using as the flywheel.
Now while you demonstrate, we get to see big sparks from the output.     be careful, we dont know what the output will be till you try. ;]

Keep uP the good work woops. Ill be joining you in a few days with this, as i have something I need to test on these bi-toroid theories.
I thing there can be many ways to separate the secondary induced fields from the primary field, and that is key for not having an increase in primary current as secondary load current increases. And safe, its just a transformer. ;]  i like safe, no like nuke. have you read today about where we store used fuel rods these days? Same as Japan, and they are holding more than they should, at every plant. =[

Woops, one more thing

Ive been told that those caps have a built in resistor, that looks like why your charge voltage is declining as it sits. Some of these caps have the resistor welded to the outside terminals and can be removed.  these caps can hold very high voltages. Ive picked up a few charged caps in my time that I was shocked, literally and not ;], at what 200 or 300v in a tiny cap can feel like, but up to 2000v     Thats why they have the resistor so the voltage doesnt stay in the cap when not in use.
