*** 20th Anniversary: 2003 to 2023 ***

This was something we had to be creative about in school. I was in Junior High and had to build a telegraph. We created it out of wood, inserted a nail, cut a tin foil and placed it right above the nail; there was wire wrapped around the nail attached to a battery and a light bulb. Every time you touched the piece of tin to the nail the bulb lit up.

Do you have concerns about air pollution in your area??
Perhaps modelling air pollution will provide the answers to your question.
That is what I do on a full-time basis. Find out if it is necessary for your project.
