Smog produced by rotating tires.
The telephone is not the only source of electromagnetic smog. On behalf of the Federal Office of Public Health (FOPH), the Automobile Engineering Section of the Haute École
Biel technical et Informatique (HTI) made precise measurements of the electromagnetic charge inside a car.
Measurements taken on 12 stationary vehicles, engine switched on, revealed weak electromagnetic fields of the order of 0,1 to 0,3 μT. These values are considerably higher when the vehicle is moving, since they average 3 μT. Near the feet of the front passenger and in the area of the rear seats, we even measured peaks at 9,5 μT. If these measurements are well below the values
international limits, however, they exceed the usual daily electromagnetic loads (0,1 to 0,2 μT).
Lost and harmful energy recovered from our cars?
It is out of reach given my knowledge of magnetism but I know that among us there are people who are capable of dealing with this kind of subject.
