text: what do i need to do to block the burning of ozone when i make a tesla coil?   you need to have no oxygen nearby.  atmospheric oxygen (o2) gets converted to ozone (o3) in the neighborhood of electrical discharges and high fields.  there's not much way around it except to keep the oxygen away from the electric field.    you could do this by putting your tesla coil in a pure nitrogen atmosphere, for instance.  (be careful, obviously, as no oxygen = asphyxiation!)
