Special Pollution Meter

A system designed by Don Stedman, of the university of ENVER, allows to know the degree of pollution by vehicles in movement.

More than a third of the vehicles circulating in Britain, for example, generate a level of pollution higher than that admitted by the administration.

Stedman places an infrared source on one side of the road and a detector on the other side. Thus, it measures the combustion residues of passing cars.

Then a computer analyzes the results. When connecting to a camcorder, the results obtained by the computer come together with the car seen from the camcorder. The camcorder can catch a car of about a second. Stedman has measured in one hour the emissions of more than a thousand cars. Save the results on floppy disks.

As the atmosphere dilutes pollution, the Stedman system does not measure absolute levels. For example, the level of carbon monoxide is calculated from the level of carbon dioxide, known for the ratio of carbon dioxide and carbon monoxide produced by each fuel.
