Electrified Omnibuses

Nature volume 142, page 713 (15 October 1938) | Download Citation



MR. A. E. WISEMAN, 21 Hanbury Road, Acton, London, W.3, writes stating that on boarding an omnibus recently, he felt a distinct electric shock on grasping the metal handrail, with one foot on the step and the other on the pavement. The effect was also observed by others, particularly on 'crisp' mornings. He suggests that the electricity may be caused by the friction of the tyres on the ground, which incidentally insulate the body of the bus. It is of interest to note that this effect was described in a letter in NATUBE of June 29, 1929, p. 981, by Sir Charles Boys, who observed it on a hot dry day and ascribed it to the scuffling of the tyres on the polished asphalt.
