Nothing is likely to provide a more effective method of converting the large amount of energy stored in fuel oil into power than the diesel engine. The major drawback to the use of fuel oil as a source of energy is pollution by exhaust emission, noise, and in the case of commercial vehicles pollution by physical intrusion. It is possible that the delivery of goods to towns and cities will be restricted to payload lots of one to three tons. This requirement would be adequately met by the battery powered electric van, which as well as being non pollutant can by means of power stations use coal as an energy source. Although there are over 40,000 milk floats operating in Britain, the battery powered van is scarcely used by many other operators. Once battery operation becomes more flexible, and battery life cycles can be increased from 300 to 1000, fleet operations will be possible where weekly runs differ from day to day. Maintenance training will be needed to diagnose and repair faults. Servicing may be made simpler if the new advanced vehicle systems avs-hobbs torque converter, already installed in the avs marina 6 cwt van, replaces the complex 'chopper' system. The AVS system uses a much lighter and cheaper shunt driven motor running at a constant speed, the torque converter and borg-warner transmission providing an infinitely variable drive. /TRRL/
