LIQUID COAL

TO BE USED INSTEAD OF PICT 808. Ihe advent ot a ",Wh\ coal age’’ «'«s hailed in a series of notable pronouncvincnts by chemists, mining engineer*. and fuel experts at the session 0 f tile international conference on I,numinous coal lie'll at Pittsburg on Novcrnber 18. The world, all ill. speakers .greed, was now on the thresnold of a 1 ew a m which it will be deemed ,i ii'im.nal waste to hurn law coa’ as fuel instead of first extracting the .ountless valuable ch liiical compounds winch are far more valuable than iieut from burning coal. Dr. It. lyessing, consulting engineer, lam don. dwelt on the appalling wastresulting in .Britain from the burning of coal which was not cleaned. He calculated that the tonnage of ash in the yearly coa] production in the United Kingdom exceeded by 25.000,000 tons tlie output of iron ore. Tlie, cost of I the railway truusport of this, useless material amounted to £5,000,000. Add to this tlm cost of the handling ct the ash. disposal and so forth, and it would he seen that the non-productive expenditure in Great Britain from the burnbig of coal ranged from £10.000.000 to €20.000.000. .Mr Walter K. Trent, milling and metallurgical engineer. New York, declared that the process of pulverising coal to tlie consistency of talcum powder, so that it becomes fluid when healed and runs like water, would be followed by the use of this new coal in ini. rnal-com bus lion engines instead of petrol. In a fen weeks’ time the first m.ntor-engine to ps operated by oil obtained bv pulverising coal would make its appearance in Kansas City.
