Re: Ionic propulsion/ pinwheel toroid



Hi Dr R.,

                Believe it or not, it might actually be possible.

The diodes I'm speaking of are Philips EHT rectifiers designed for 
use in monitors and TVs.  I bought a bundle from them (stock they 
wanted to get rid of) for about NZ50c a few years ago. They are 
glass passivated but you can get around the lead-lead creepage 
ratings by covering them in heatshrink.  The sorts of rating we are 
talking about are 20kVrr, recovery times in the sub uS range, Iav 
around 3mA or so and Ipkr around 500mA !!!  So far I've only used 
them to rectify test eqpt. type flyback chargers but....
      In the same breath, I'm sincerely sorry to say I have none for 
resale. I have given a few away over the years but am hanging onto 
the rest with a view to using them in various projects. 

Regards,
malcolm
