One day last week Mr. J. V. J. Malone read a paper before the Royal Society of Arts, London, on the subject of "A New Prime Mover." The system of power generation involved has taken many years of research work and is now at the stage when it can be applied to commercial work. In the case of a road vehicle it is most convenient to take a conventional steam wagon as a basis for comparison. A wagon equipped with a Malone engine would have a furnace, what is termed a generating unit, mad a reciprocating engine. .The generating unit replaces the boiler ; in it water operates in a closed circuit and in its passage through the system is raised to a high temperature an then reduced. The resultant increase of pressure is employed to operate the reciprocating engine. It is claimed that the thermal efficiency is about double that of the present steam engine.At one • end of the generating unit water is at atmospheric temperature and in the course of its passage rises to about 675 degrees F.
There is no water to be replaced in the unit and no parts to require attention. Between the,engine and generating unit the connection is by pipes so that the engine can be located at a distance.
As applied to a vehicle the space, weight and cost of the motive portion would be equal to Corresponding figures for modern steam vehicles.
A single lever controls engine direction and speed ; if the fire be banked overnight an immediate start can be made, or there would • he only a few minutes' delay if the fire had to be lighted. We hope to deal further with this power system in our next issue. In the meantime those -interested can communicate with Mr. J. P. J. Malone, Rothbury Terrace, Neweastle-on-Tyne.
Manchester Impressed by the Economy of Motors.
Some striking economies have been effected by the cleansing committee of Manchester Corporation by the employment of motor vehicles in place of horse transport for the collection of house refuse. A short time ago tests were , made with various 'types of vehicle anti when the costings were worked out it was found that the average cost of collection by motor freighter was 4s. 4.42d. per ton and by horse-drawn vehicle Os. 0.98d. per ton. •
With regard to road sweeping, it was found that a motor sweeper could sweep 10,000 sq. yds. of surface at a cost of 5s. 3.42d., whereas with a horse-drawn sweeper the cost was 8s.9.18d.
On the strength of these results it has been decided to purchase five dustkss7loading vehicles,. a freighter chassis, a tipping lorry and two Lacre road sweeping machines.
A New Bus Park at 'York.
The watch Committee of York Corporation has reconsidered the question of providing parking places and recommends establishing a parking place for buses in Foss Islands Road and discontinuing the 'present place on Lord Mayor's Walk. Consideration of the question of other parking places has been ,postponed until the 'Chamber of Trade has intimated its opinion on the one-way traffic proposal.
