The substances of this second class are obviously much less complex, both as regards the different kinds of atoms and in respect to the numbers of each kind that enter into the formation of a single molecule. Therefore the carbohydrates do not possess so much power or energy as the protein molecule; in short, they are not such good fuels for the living mechanism.
Our non-productive departments consume a great deal of material, mill-supplies and fuels, but if we include those with all the rest of it, our figures will not show a right proportion." "What do you mean by your non-productive departments?" asked the boy. "That seems rather a curious phrase." "Those in which the work done is not directly a part of the making of guns or ammunition.
Fuels and foods are also alike in another respect; and that is, that, no matter how much they may differ in appearance and form, they are practically all the result of life. This is clear enough as regards our foods, which are usually the seeds, fruits, and leaves of plants, and the flesh of animals. It is also true of the cord-wood and logs that we burn in our stoves and fireplaces.
How is the "man-motor" like an "auto"? Compare the fuel of each. 4. From what source do all the fuels get their force or energy? 5. How do plants get their fuel, or food? 6. What is meant in saying that man takes his food at second, or third, hand? 7. Why do we need a mouth? 8. Does a plant have a mouth? Where? 9. Draw a diagram showing how the food is carried into and throughout the body. 10.
I will ask for the funds needed for energy research and development activities. I have established a goal of 1 million barrels of synthetic fuels and shale oil production per day by 1985 together with an incentive program to achieve it. I have a very deep belief in America's capabilities.
Inasmuch as heat is so important a factor in the cooking of foods, it is absolutely necessary that the person who is to prepare them be thoroughly familiar with the ways in which this heat is produced. The production of heat for cooking involves the use of fuels and stoves in which to burn them, as well as electricity, which serves the purpose of a fuel, and apparatus for using electricity.
We may regard it, therefore, as an island upwarped from the sea at the close of the Ordovician or shortly after. PETROLEUM AND NATURAL GAS. These valuable illuminants and fuels are considered here because, although they are found in traces in older strata, it is in the Ordovician that they occur for the first time in large quantities. They range throughout later formations down to the most recent.
But Jupiter offered the greatest possibilities for quick settlement, a base from which they could more easily operate, a base for fuels, for the heavy elements they would need Fifteen million miles from Jupiter they slowed below the speed of light and the IP stations observed them.
Coal involves a different theory of time, because coal, unlike a tree, is produced on the scale of geological time. The supply is limited. Therefore a correct social policy involves intricate computation of the available reserves of the world, the indicated possibilities, the present rate of use, the present economy of use, and the alternative fuels.
Well, droughts, floods, and historically low prices have made times very bad for our farmers. We must work together to strengthen the farm safety net, invest in land conservation, and create new markets by expanding our program for bio-based fuels and products. Today, opportunity for all requires something new: having access to a computer and knowing how to use it.
