   Sorry for the intrusion but it is weird I was thinking about producing a Tesla coil/cap and putting it on a moped I adapted for electric drive.  The bike as it is works on 24vdc.  I control the bike with a variable field flux drive.  You open this baby up at around 20mph and the bike takes off like a rocket till it becomes a little hairy.  Mopeds don't like going over 30mph.  The coil cap is light compared to the batteries but the voltage is really hairy.  How the heck can I step this down to 24 v while still maintaining control of the discharge.  Vacuum tubes capable of 10,000 volt tube bias and grid isolation are hard to come by if at all.  Any ideas would be appreciated.

I have been playing with the Bedini SSG again.  I tried making a square wave output using N - S magnets, but failed.  It can be done with more complication.  I tried to use brushes alternating the field but the drag from the brushes wouldn't allow spinup without a lot of power being used.
So back to the classic design with a few mods.  I added an isolated secondary to see if I could backcharge.  It works, but I may have it out of phase. 

If there is a way to have input equal output it seems to me the energy has to enter the system from somewhere.  It can be a seemingly passive entrance of energy from magnets passing by coils, or a siphon of energy from around us.  It is good fun and good exercise for my curiosity.

This topic doesn't belong here.  I should put further information in the right thread.

  I liked your vid, Lynxsteam -- very nice, as usual! 

  You note at the end that the LED bulb draws half the power, compared to the LJL (if I understood properly).  Any explanation?

   Also, what kind of diodes did you use in the FWBRectifier?
Thanks again.

Joule Seeker,

First - that bulb is a 3w Phillips LED.  For some reason it pulls a lot of power off the grid and off my LJL, so I don't typically use it for analysis.  It would normally run at 1.2 amps and 12 volts.  But on this Bedini motor it pulls about 600 ma.  I think this is because it is half bright.

The Bedini motor or oscillator is not a great way to run the LEDs.  The frequency is slow and the pulses are choppy instead of the nice smooth sine wave from the grid or the fast chopped output off the LJL.  But I am just starting to explore.  A smoothing capacitor would help.

Those diodes are 1000V, 1 amp IN4007

I changed today to a smaller power coil and rpm is much higher, amp draw lower.  If I am going to generate voltage above battery the rpm will need to be high. 

Playing with the trigger to maximize transistor off time and maximize induction time is the key to self running.  I doubt I will do it, but it is fun to try.  And it is fun to watch that wheel spin so fast on such little power.  The video was just a montage of things I have tried so far.  YouTube should be entertaining.

I found something interesting.  Playing with the larger aircore LJL I hooked up a 120 v LED bulb with no transistor.  No collector at , no base connection.  The bulb lights at .3 watt or .7 watt depending on the dim switch setting.  I will post a video later.  Off to go water skiing.  Its hot!
