"Safe" 5000 V

Yes, thats true, if you design a high voltage power supply with a high internal impedance then the output current will be too low to kill. For example if a 5KV supply has an internal impedance of 5M then the closed circuit current will be only 1mA

ok back on topic,

I don't consider Tesla coils a safe source of HV, Van de graff generators are.

You can make also safe HV source by driving a fly-back transformer at 10KHz and conecting the output via a high voltage capacitor to limit the current.

Anyone knows what dragon ball Z is? I thought about making two gloves that will fire sparks from one to another, but was scared I might kill some one.


As I said in my previous post, if you limited the current to a safe level you wouldn't cause any injury or death. Never the less I don't think you're glove idea is any good because the insulation on the gloves would have to be very thick to stop the electricity passing through the wearer.

Let's do some calculation: to make a spark between the two gloves, let's say they are 0.5 meters apart from each other, since dry air discharge break voltage is 3MV per meter, you need a 1.5MV = 1500 V (DC voltage) between your hands. I wouldn't play so close to it. Besides 5000 V seems to me extremely exagerated to obtain the spark.

Half of 3 million volts is 1.5 million volts, isn't it?
It isn't exaggerated. There is a link on another post to a 1 million volts DC thingy that produces arcs Four Feet Long! It uses four TV flyback transformers in parallel to power its voltage multipliers. I don't think anyone wants to be anywhere near it.
