Re: Tesla List

In actuallity, if you are trying to get 1nf, a simple bottle
capacitor(leyden jar) is all that is necessary.  For 10kvac, and higher
capacitance, you might be able to use a rolled capacitor, 20 layers of
saran wrap and aluminum foil.  About 100 square feet of dilectric should
get u at least a 1uf.  Mathematically, it would get u about 3, but it is
quite hard to things super perfect  Check your high school physics book
for the dilectric formula and charge storage.
