Two engineering students and I received EPA funding to build a portable nitrous oxide meter to measure auto emissions at busy intersections, etc. My job on the team was to build an ozonator.
It was fabricated from an outer 3 inch plexiglas tube and an inner 2 inch plexiglas tube both about 10 inches long. The outside of the inner tube and the inside of the outer tube were lined with metal conducting foil. The inner tube was grounded and the outer tube attached to an electrical current.
When the current jumped from the outer to the inner tube it looked like hundreds of little bolts of lightening and the electrical arcs generated the ozone. Add a small fan to one end of the tubes and a steady flow of ozone was created.
What about Bob?
- Bob Tetu
- I'm an engineer with a background in six industries - chemical, medical device, printing, semi-conductor, banking IT, and the internet. What a ride! Hobbies include carpentry, cabinet work and gardening. Making props for school plays and after prom is a volunteer past-time. Basically, I love to understand how all things are made and I hope I can connect to others with a similar interest.
