All,
I've been meaning to share my thoughts on the use of a vacuum cleaner
blower to negatively pressurize a fixed gap spark gap container and
draw outside air through the gaps and then after electro-treating the
nitrogen in the air into nitric acid and the oxygen onto ozone, this
nasty stuff gets sucked through the windings of the blower motor,
since vacuum cleaner blower motors are designed that the air sucked by them
passes over and through the motor windings for cooling. Has anyone ever
heard of the concept that ozone attacks electric motor insulation and shortens
motor life? Somehow this design concept appears flawed to me.
