His question is also not pertinent to this thread and furthermore the answer he seeks is easily found in the FAQ's. Providing he complies with the registration rules, answering his question will serve to skew / hijack the linear flow of Joe's post.

ok sorry
i have fixed that and put in my real name and my about me.

what should my power supply be rated at?

Fusion power supplies are not set at any voltage or current. Instead they must be totally variable from 0 volt to a maximum determined by the user. Demo fusors are easily run by oil burner ignition transformers controlled by a variac. They are typically rated at 10kv @ 20 to28 ma. A neon sign transformer is more often used in the 12kv to 15kv range and rated at 30ma. High voltage diodes are needed to turn this into DC.

All of this related to a demo fusor is in the FAQs which it is now obvious you have not read at all. Demo fusors do not do fusion....

Serious, real fusion fusors demand a minimum of 30kv @ 30ma capability or more. This separates the men from the boys. Top level fusors use supplies that are capable of running well over 40kv @ 30ma.
Again, all of this is in the FAQs....Read them....
