During the pioneering days of the motor car, it wasn’t altogether clear which method of propulsion would best be suited to personal transport.
The topic was discussed in most issues of Autocar, and the 4 March 1899 issue reported on “an interesting and practical lecture on motor cars” given by Mr JS Critchley, manager of the Daimler Motor Company’s works at Coventry, to the members of the Coventry Engineering Society.
Critchley was quoted as saying: “At the present time, there are three sources of power for motor car work: steam, electricity and mineral oil.” He went on to assess the merits and drawbacks of each method of power.
“Steam vehicles have the natural advantage of not requiring a variable gear,” he said. “The engine itself is self-starting, reversible, simple and well suited for the work. The boiler and its accessories are, however, the great drawbacks, both from the points of view of time taken in varying its generation of steam, without increasing risks of clogging, and of dirt and smell.”
Although “the electric motor itself is as well suited for vehicle propulsion work as could be wished”, the battery-powered vehicles also prompted logistical issues, said Critchley. “Since at the present time it is impossible to convey externally generated electric current to the carriage while travelling, some kind of accumulator is necessary,” he went on. “The only ones now known are expensive, troublesome, heavy and generally unsatisfactory.
“For a vehicle to carry four persons with a total weight of one ton, about half this weight was now necessary for the storage battery alone, and its capacity was only about three hours without recharging. An enormous amount of improvement is necessary before they can become really successful except for use over small areas.”
