frequency tesla coil function a? IRF9130? circuit cold electricity?

at what frequency does a basic tesla coil function at? how does the IRF9130 fit into the circuitry when it only has 2 posts? does a circuit require a spark gap to induce cold electricity and what frequency does it first take effect?

I will be putting together several joule thief's and after i get them to sustain each other i intend to use the circuit with the IRF9130 to power a tesla coil. i also intend to use the JT to power an E-bike that is fast enough to travel on the highway's.

any help is greatly appreciated!

also, what is a Batt-cap? and where can i find them? the batt-cap in question is stated to absorb all of the batteries power and recharge it after it is fully depleted. source from:http://free-energy-info.co.uk/Chapt5.html

Use an IRFP460 instead of a IRF9130 the circuit will work better.

A regular spark gap Tesla coil runs between 100-500 thousand kHz, this is a rough average, you can't really say any specific frequency.

This circuit is not a Tesla coil, but it can be used to power one.

The 45kV only stops electricity flowing to the coil with the top terminal (in the diagram) the electricity flows through the bottom terminal. The other diode, I am honestly unsure but I know that if you use a IRFP460 it already has one built in.

In a SGTC a lower frequency will generally produce a higher voltage (due to the way the circuit works), but a higher frequency is better for wireless electricity transmission.

A SGTC is a spark gap Tesla coil.
An IRF9130 has a lower voltage than a IRFP460 this means the IRF9130 may fail in the kind of circuit you're building.

IRFP460 not IRF460 however the two do seem quite similar.

I have done experiments using Tesla coils and resonant coils the max result is about half of the output power. I am still going to continue sometime with different forms of resonant circuitry.

Everything you need to calculate resonance of your two coils is on this site, just use the helical coil calculator then from that the LC resonant frequency calculator.

Yes I have played with TC receivers, you will have to play with the topload of the receiver to fine tune it.

Well with a Tesla coil yes.

The effectiveness of the system was useless but I am yet to test other ideas.

I really don't know much about joule thief's, but you might like to try the circuit on this site, I've been meaning to try it sometime. This circuit would be interesting around a Tesla coil especially if the antenna is a resonant coil or possibly fractal. 

The other ideas I am yet to test involve these, I find them much more interesting than Tesla coils because the circuit can be manipulated more to do other things like receive power.

It is unlikely you will be able to power a Tesla coil with 1.5V batteries as well as an ignition coil. 6V lantern batteries will be able to do the job poorly (I used to use them, they worked fine for small scale Tesla coils).

A reed switch looks a lot like a relay if so it would be suitable to create an electric pulse (I have done it before whilst connected to a transformer), with the pulsing you should be able to connect it to an ignition coil and have you're power source. See this.

What do you mean by ordinary and cold?

Unfortunately I cannot help you there, I don't know enough about generators.

No worries and it's a bit odd that you're getting a google search thing with me it searches the site on the site not through google.

  1. The metal case is the Drain ( 3d terminal ) of the IRF9130.
  2. The Gate ( pin 2 ) goes to the 470 Resistor.
  3. The Source goes to +12V
  4. The 555 is oscillating about 100 Hz
  5. Tesla coils operate at RF you want current to flow over your skin not through it.
  6. Cold electricity ? 
  7. Joule thief's suck batteries dry and cannot power an E-bike !
  8. There is no such, good luck ;-)

Combining NPN transistors can only increase the current and slow down due to parallel junction capacitance.
Each collector must have a 1 ohm resistor in series as does each base require a resistor.

You have a strong single minded obsessive need
Mine is collecting best answer author gratuities.
While at present your too centric to get it.
I do respect your multifaceted pursuit of an impossible goal
That drive can serve you well.

Sorry man you have no grounding in electronics and that makes you a sponge for fun lies.

Try Logic, Don't you think the material you squeeze out here would be in production, available to all consumers,  if there was Real engineering behind the claims ? ?

Sounds to me like you think you can get free energy from this setup, which you can't, ever.
