We must bear in mind that electricity is never a source of power, but is only the agent that carries power to the user. The source of all electric power is either steam or water, produced by water-wheels, turbines, steam-engines or gas-engines. The economical way to furnish electric power is to establish central power plants, and electricity may be conveyed from them for many miles.
Gas-engines are already very largely used as the actuators of electric lighting machinery. But in the developments which are now foreshadowed by the advent of acetylene gas the relation will be reversed. In other words, the gas-engine will owe its supply of cheap fuel to the electric current derived at small expense from natural sources of power.
Dry peat without a binder, or mixed with coal dust and tar or pitch is used for the same purpose. Machine peat is used for many purposes, among them making into briquettes, peat charcoal, and peat coke. It has been found practical to make illuminating gas of peat, but a far more general use is for running gas-engines and producer-gas furnaces.
The extent of the loss by the cooling water was thus well ascertained; and it was no doubt by a reduction of this loss that further improvement in the working of gas-engines would eventually be obtained. Mr. He said he did not rise with a view to make any observations thereon. The analysis of first principles required more matured consideration and thought than could be given to it here.
The manufacturing industries of the country waste a large amount of fuel annually, but here the waste is mostly due to expensive methods of producing power, and to careless stoking, and is largely preventable. As we have shown, gas-engines are a far more economical form of producing power than are steam-engines.
On inquiring into the matter, he discovered that the same thing frequently occurred in other places where gas-engines were in use; and this caused him to design a contrivance to put an alarm-bell into action at the instant when the water ceased to flow, and so enable any overheating of the engine, and injuries thereby resulting, to be prevented in time.
He had but one room: bare pine floor, small work-bench, wall bunk with amazingly neat bed, frying-pan and ash-stippled coffee-pot on the shelf behind the pot-bellied cannon-ball stove, backwoods chairs one constructed from half a barrel, one from a tilted plank and a row of books incredibly assorted; Byron and Tennyson and Stevenson, a manual of gas-engines, a book by Thorstein Veblen, and a spotty treatise on "The Care, Feeding, Diseases, and Breeding of Poultry and Cattle."
As regards the steam-engine, it is the opinion of competent authorities that the limits of temperature between which it works are so restricted, and so much of the heat is expended in producing a change of state from liquid to vapor, that little further improvement can be made. With respect to gas-engines, the limits of temperature are much further apart.
The remainder of the Belgian exhibit of machinery may be summarized: rock drills on the principle of those used at Mont Cenis; the gas-engines of Otto; machine tools, lathes, drills and planers; a very curious machine for cutting bevel or straight gears, built by a firm at Liège, and worthy of attention by Mr. Sellers or Mr.
Don't you feel the pace we're going now? I expect we're showing our heels to one of them, and shall show them a good many times between this and the first of next month, though Karl below is grumbling about the oil again: you want gallons of it with gas-engines. If we don't pick up the tender to-morrow, it's a bad look-out."
