The energy which the sun radiates(辐射) goes in every direction. But only a minute part of it falls on the earth. Even so, it radiates power of about 5,000,000 horsepower per square mile per day. The sun gives us as much energy every minute as mankind uses in a year. At present, we use this energy indirectly, and it is our final source of power.

Coal(煤) represents the chemical action of the sun on green plants thousands of years ago. Water power results from the rain formed by vapor when water changes into gas under the sunshine. Even windmills(风车磨坊) operate because of air current(流) starts moving by the different heating effects of the sun in different places.

Someday, through chemistry or some types of solar engine, we should use this great source of energy more directly. Already a scientist has worked out an engine, surprisingly doing well, in which the sun’s rays are concentrated through mirrors on water to create steam.
