The Outlooks Fuel Conservation WITHOUT knowing the rate of output of aircraft engines, it is impossible to estimate accurately the number on test at any given time, but prob ably 500 would not be an unreasonable figure if we include reconditioned engines on test. All of these will not, of course, be in the 1,000-2,000 h.p. class, nor will all of them be running at full power at any given time. But it does not appear extravagant to assume that the average power would be at least 50 h.p. ; every day and all day half a million horse-power is running to waste. At s& consumption of one-half pint per horse-power per hour, Tthis represents something like 3,000 gallons per hour, or 37,000-38,000 gallons per 12-hour day! If the fuel used were home-produced, such waste, although bad enough in all conscience, might be toler ated, but it is all imported and has monopolised valuable shipping. The Atlantic situation is not such that one can view waste of this magnitude with equanimity, and^ the Managing Editor of this paper and its sister journa" Aircraft Production, has for some months advanced pleas for this tremendous power to be harnessed to useful purpose by being converted into electricity. All manner of objections have been raised, and it has been pointed out that the difficulties are too great, the labour involved and the loss of time too serious, for the scheme to be practicable. The August issue of Aircrajt Production publishes an article by an electrical expert in which it is shown not only that the scheme is not impracticable but that it is actually being carried out by one leading firm, and that deliveries will begin at an , early date. Obviously the installation of the necessary equipment must be spread over a period, and the substitution of regenerative electric dynamometer's for the water-brake type of absorption dynamometers that have served us until now will be gradual. But it is not necessary for the effective working of the scheme that every test bench in the country must be converted before the scheme can begin to operate. Every7 one converted will add a little to the power mains until, with most of the test benches converted, the saving in coal consumption by the useful expenditure of petrol will amount to a very impressive figure. It is urged that the cumulative effect of this saving and the consequent reduction in the number of miners who would have to be taken out of the Army— or, alternatively, of the hordes of clerks that would be necessary in any rationing scheme—would be enormous, and difficulties, technical and otherwise, should not be allowed to^irim in the way. Efficiency and economy are theJ*^notes of production to-day. mud runs and the R.C.A.F. T HE Canadian Minister for Air, the Hon.
