I am with you there Res.
Lower voltage and portability.  A cap can be a High Tension source. Getting that charge is easy and high freq helps to keep it that way. So lets say we use a reed switch to make our spark gap, or make and break as Tesla first used before the spark gap. If we have a reed relay, we can easily get the reed to pulse at fairly high freq and use diodes to stop the back feed, as Tesla claims. I have some big reeds that I will have to use a larger coil to operate as compared to a reed relay. Now where I am at with it is what do we do with the output of that pulse. How do we utilize the RE into usable energy. How is that excess manifested. Im still reading.

No need to use diodes when you have Edison DC  generator with commutator 
Reversals was not possible at all because commutator was acting as second spark gap - btw this is why commutator was invented - to prevent AC ha ha, of course by accident .
What is happening with magnetic field of solenoid if circuit suddenly is opened on both ends ?
It has to dissipate somehow....
Btw capacitor can also be a gap in circuit...

Well we dont have an Edison dc gen handy, also most of Teslas Impulse projects did use the gen as a source.
But he still had to use a magnetic spark blowout setup. Just to make the jump a pure one way situation.
Can you elaborate on the cap as a spark gap? Tito mentioned that also. He had me going on using a zener diode, and then said that he didnt use that anymore, he uses a cap. So now Im really lost. In that respect anyway.
Thanks forest

A  reed switch may be a good place to start ........along that line  there are also available small preset spark gaps  I do not  remember what they are called...... a couple people on the earth battery thread were experimenting with  them    I will  have to look them up .

Any device that uses a spark gap of any kind  will eventually fail because  the spark carries a small amount of metal with  it each time.

I want  a build it and  forget it kind of device.
I do not want to have to keep adjusting  a spark gap to keep it running

My idea would work kind of like  a mag amp.
It would have 2 cores  an input and an output core./
The power level that it runs at would  be set by  the input coil  and core.
The input  coil will make magnetic flux that will  go into the input core
The vast majority  of the flux will stay in the core unless enough power is used to saturate the core.
Once the input core is saturated the magnetic flux will start to flow outside the core
This  core will need  a non magnetic spacer around it for this excess flux to flow in

I am thinking  that the output core should  be of higher permeability  or  have more iron content  than the input core.

Assuming  we  have enough power  to have  the input core saturated  and flux flowing  in the space  between the 2 cores.  If we add a little more power  the  flux will have enough volume to be flowing near enough to the output core to be attracted to it..

If  the  output  sore is more attractive to the flux than the input core......the majority  of the magnetic flux should  jump the gap kind of like  a magnet jumps to a piece  of iron.

So far  I have not  got the jump to work.
The best I have done is  to  have a coil  that lets the voltage below  a certain voltage through on the input  side.

Voltage above that level appeared on the output  side.
This was  done on a toroid.
Toroids really suck for this kind  of device because  the winding is not uniform from  inside to outside ,

I have breen meaning to try  a couple  E cores I got a while back
The question is.......what  do I use for a input core.
The input  core would have to be added to the coil after the output coil and the flux gap.



Another thing that might work  with this kind  of coil.
If an extra winding  was placed in the gap  between the  input  and output cores  this  winding would either aid  the flux in jumping or inhibit it depending on its polarity  ......it could  be an inductive triode.

I am thinking it would be really cool to  use  a bifilar JT as the input winding  of one of these coils.
If the  input  core and gap were tuned right  we would end up  with a string  of  pulses with a very high rate of change.........these pulses should  be usable   on  the caps and rods  of a small hairpin
