Tony,

Years ago (7 years?) I saw a demo show at Harvard where Wolfgang placed a
small Jacob's Ladder inside a sealed jar.
He let the Jacob's Ladder arc for a while inside the sealed jar. It filled
the jar with gases. Some of the gases it produced were nitrogen oxides and
ozone gas. The same components of urban air pollution. The gas was
heavier than air. Wolgang then demonstrated refraction with the gases by
using a Schlieren Optics arrangement. As you may know, Schlieren Optics is
a sensitive optical system that detects the inhomogeneities within air by
using refraction.

I think the Van de Graff sparks and the Wimshurst machine sparks also
produce ozone.

Time to plant the beans, the corn, the tomatoes, the peppers, the lettuce,
the...

Tappers,

 What can you folks tell me about about Ozone generation? I need
some

ideas on how to safely generate small amounts of the gas to use for

calibration of sensors and for training purposes. Also any info on
known

detection systems would be much appreciated.



Thanks,

             
Tony
