Woah that is crazy you should get a video of the tesla. How do you switch it?...
Switching is by a big heavily spring loaded switch activated by pulling a plastic spacer out with a very long string. Very crude but effective and reliable with minimal wear. I don't even think about the switch any more.

The video would be disappointing I think as the beauty of the picture is in the homogeneous trails seen in high resolution. It is all over in 1/2 second anyway. I have new video software but need to get up to speed with it. I have lots of room as I only have used 144M out of my 2 gig quota on Chris Russell's 1121.org server.

I am not sure how long a plasma channel I can get with very fine wire which is what I might try next.

That beut I can't find any braided copper wire so I thought I might just make a mechanism that drops the wire I want to explode onto two points. I have 20x 450V 1800uF caps so 3.645kJ of energy might do something. But they are elctrolytics and on your web site you said they are slow? Is that because they are low voltage.

Try an auto parts place or wreckers for braided battery cable.
The wire needs to be fixed securely or it will just spark at the ends so just dropping it won't work well and you will probably be too close.

Electolytics are slow so won't work for can crushing, but the energy still has to go somewhere.

Here is 1500 J of electrolytics and some aluminium foil.

You have the right to show off shades

I tried dropping some solder onto two steel bars that were the electrodes of one 450V 1800uF and that worked well, it didn't just spark at the ends.

I don't feel the urge to crush cans unless I'm at the recycling centre it doesn't appeal to me. But exploding wire sure does. Next-to-do is to ramp up the bank to include all 20 and make some nice shiny iron electrodes (I know iron is a bad choice but I have plenty off it for no cost).

I calculated that a 0.5mm diameter and 5cm copper wire would be heated to 74000ºK ¿do you know if there where any reflected power?

Peter,
Nice photo's !

I suspect
1) The magnetic field generated by the transformer has little to do with the effect
because by design the flux is almost entirely within the core.
2) It's probably just Lenz's law at work
If you 'shield' the transformer with a metal plate (pass the wire through a hole)
I suspect you will get a similar result
even aluminium or copper etc. should 'spread' the arc due to
the magnetic field created by the current of the arc itself.

Just speculating.


Still nice photo's though!
