SOLAR ENERGY

       Our Sun, although it is not the largest star in our universe, is a gigantic body. If we make a non-stop flight around it in an airplane at a speed of about 300 km per hour, it will require 565 days to go around it at the equator. The diameter of the Sun is 1,391,000 km, that is, 19 times that of the Earth. The Sun has a surface temperature of about 6,000°C.

       Modern research into the atom indicated that under certain conditions the matter itself may be transformed into energy. It is now thought that the source of the sun's energy result from nuclear fissions and is practically unlimited.

       Man has used and is still using solar energy through photo-synthesis as one of his sources of heat and power. Another way to use solar energy is in the solar machines, still another is the use of solar heat for cooking and house heating. The future will undoubtedly bring us a lot of new applications of solar energy.
