When we begin to study the mineral resources of the country we pass to conditions altogether different from those which we have been considering. Heretofore we have been dealing with resources that can be renewed, the soil by proper management, the forests by replanting, the waters by nature's own processes; but the fuels, the iron and many other mineral resources once used are gone for ever.
Wood, which was formerly the only fuel used in this country, has now largely given place to other fuels. In rural districts and in lumber regions it is still used extensively; but in the cities, larger towns, and manufacturing regions, it is not used in commercial quantities.
Concerning that particular function of mobility which is called coal endurance, that is, the ability to steam a certain distance without stopping to recoal, the convenience to military operations of such a quality is evident; but it is obvious that it cannot, with the fuels now available, be possessed beyond very narrow limits.
In these calculations of the heating power of gas and coal no account is of course taken of the loss of heat by radiation, etc. My object has been to compare these two fuels merely as regards their actual value in heat units."
Do not increase your working pressure without first re-testing the boiler to double the new pressure to be used. Fuels. For very small stationary boilers the methylated spirit lamp is best suited, as it is smell-less, and safe if the reservoir be kept well apart from the burner and the supply is controllable by a tap or valve.
This is a chemical test. The wood of the match is plainly of vegetable origin; so also is the charcoal, which is nearly pure carbon. Coal is also carbon, the remains of ancient forests, from which the gases have been slowly driven off by heat and pressure. All the common fuels are composed principally of carbon and hydrogen.
Of all our minerals, the fuels which supply heat, light, and power for domestic and manufacturing purposes, are the most necessary and important. Other materials can not be manufactured without their aid. Almost every particular of modern life would be changed if we no longer had plenty of fuel.
The mangroves of the islet provided the best of fuels for the preservative smoke. The fortnightly steamer passed not so very far out, so that it would be possible to send away a couple of tons at a time without leaving the locality or suspending work for more than an hour or two. With cheerfulness and enthusiastic haste all started to work.
Every day we spend more than $120 million for foreign oil. This slows our economic growth, it lowers the value of the dollar overseas, and it aggravates unemployment and inflation here at home. Now we know what we must do, increase production. We must cut down on waste. And we must use more of those fuels which are plentiful and more permanent.
The Energy Security Act also provides significant incentives for the development of gasohol and biomass fuels, thereby enhancing the nation's supply of alternative energy sources. The Administration's 1977 National Energy Plan marked an historic departure from the policies of previous Administrations.
