Tesla coil Build comparison. (Proof of ability)

[Kamil]

Hi Guys,
For last two years I have experimenting with Tesla coils but always kept them small size ,powered by flyback which was nice and fun but now I feel like I like to move forward and build some think bigger but relatively easy just to keep cost down.
I have few MOTs and thinking about useing them as a power supply for my new project.
Can you give me some advice plus schematic which will be best to start with building big Tesla coil ?

P.S. You can visit this website:
http://isparktube.com/ is really good and I have posted there few of my projects

Regards

Making progress... this is just a test of the GIF animator... if it doesn't run inline please download and watch...

Not bad for 24 volts input, there are some streamers over 12 inches in there.

ETA: OK that didn't work, so here are some stills.

That curent is consumptio?

Nice build there TK.
I bet that would light some CFL's.

I have not yet been able to measure the current draw because it makes my digital meters freak out and I can't seem to find my moving-coil ammeter in all this clutter, if I even still have one. I know several ways to do it but they require some setting up and I've been too busy and lazy to do it. Past experience says that the driver will draw up to 7 amps when a heavy flyback output is demanded. I am using 2 Sealed Lead Acid 12V batteries of 5 A-H capacity each and they are lasting a surprisingly long time so I think that the draw must be less than 7 A most of the time.

It does indeed, lights up the ones in the bathroom fixtures dimly. I haven't yet tried it with the bare bulbs and etc.  But I have found that big sparking coils aren't as efficient as what I call "field pushers" which don't produce visible psarks. By turning the spark gap down to tiny gaps (hard to do with this type) while avoiding power arcs, one can make a sparker into a field pusher and get more range on the E field effect like lighting CFLs with no circuitry at a distance.
