Right after I got done making the Plasma speaker I wanted to work on something else that had to do with a high voltage flyback transformer. I searched on the internet, looked at videos on you tube on how to make them. I am going to show you how I made a decent SSTC that makes about 4 inch arcs. This is a good way to have both a working plasma speaker and a mini tesla coil just by adding a few extra parts!

Thank you.

How to make this usefull... Charge a capacitor bank and periodically discharge it through a transformer. Dependant on how many watthours the stacked up chargers can give, you could run a tesla coil off of a huge bank of 1.5v sources (the chargers can use 2v but why push the horses to death when you can just link up more horses to take the load?)..... maybe even the Baghdad batteries could be used! Or maybe even John Hutchinson's ammoshell casimir effect batteries.
suggestion for the periodically discharging switch: In the spirit of ancient technologies, i suggest a rotating spark gap where a metallic star, attached to a laquered shaft of wood, is rotated by a separate source (a dc motor or something) and thus if it is a 6 point star you would have 6 discharges per rotation as the points brush up against contact flaps or something.
Completely possible to have done with just transformers and baghdad batteries to transmit radio or use for highvoltage lightning.... but thats getting off topic.
The idea is using a teslacoil system in reverse (the HV terminals pick up HV static in the air and periodically discharge into a resonant transformer that stores the energy in a battery or something).
Tesla understood the research of Kristian Birkeland in his experiments with his terella laboratory. He discovered the actions behind the aurora borialis and australus. Tesla knew that charge particles were bombarding the earth every day . He realized that if the energy from the sun was only lets say positively charged particles, then the sun would charge negative and the energy would diffuse through space as 1/R^2. If the negative and positive flowed together the net charge loss would be neutral and thus the energy component would be kinetic. I dont know if he knew the magnetosphere split the charges into positive and negative but im sure he realized something like this was going on.
Basically if the atmosphere consists of this charged strata, is there a way to harness it. Basically like harnessing the power of a lightning bolt, but instead of harvesting the strike, you harvest the dipole the earth naturally has before the dielectric breakdown occurs (the lightning).
As for the low power, this is true. But to increase the power output you can link the 300Volt outputs in paralell. The acctual charging circuitry on the board takes up something like a 10th of the space so size is not toooo much of an issue. (look up coilguns on this site and theres an instructable on removing the small charging circuit on the flash camera circuitboard).
Technically you should be able to connect X amounts of these things in paralell to get Y increase in current at 300V. I've been trying to look into the use of these power charge circuits as a power supply for a post apocalypse scenario (i liked playing fallout so i see it kinda as a hobby idea... i promise im not crazy or stockpiling things in a giant fallout shelter.)
but i guess pretty large masses of em can be had fairly easily usually
And yes, it would probably take quite a few to get a good steady 10w/h out of it, but thats the beauty of the simple circuit... as many as you like could be added.
Its the 1.5V source im worried about lol... a huge HUGE bank of baghdad batteries or maybe John Hutchinson's casimir effect battery.
used for charging clouds with static energy at a certain place and then making them bump in eachother (basicly how lightning works,but I guess you already knew) and then finding an effective delivery system for global coverage
Its kinda like bodies of water.
If im in a pressure chamber and the pressure of the water rises, i can take it.
Thats like voltage.
But voltage with a path to flow is like being in that pressure chamber and then some one busts open the side of it with axe or sledge hammer or something...... All of a sudden the water would rush through a path to the low pressure open hole. Being in this path i would get hit with a current of water and possibly shot out through the hole. weee!
So when you touch one terminal its like being in that chamber. When you touch a terminal of a different pressure/voltage you create a path through yourself for the current to flow. You are in the path where high pressure meets low pressure.
I forget the acctual values of current that can kill a person. But even rediculously low amperages placed across the heart (from fingertip to fingertip) can kill a person or create toxins that are very very hard on the body. Just as a small example, if we are mostly water and putting positive and negative leads into water creates hydrogen and oxygen gas, imagine what thoes chems can do to a person.
Tesla's high frequency high voltage systems dont hurt as much because of 2 things. 1, the higher the frequency the less your nerves can respond to the flucutating electric fields.
2, there is such a low current that the wattage thats travelling through you is low (Watts= voltage*current)
3, there is the supposed 'skineffect' where the flowing charge for high frequency currents seems to exist mainly on the surface of a conducting body. True for conductors but i wonder for organisms...
anyways, if i got anything wrong, other peeps pls pls correct. Thx.
(sorry about the longwindedness but hopefully that answers the 1 question that was asked and maybe afew more that arose.)
