Sources of Power (II)

The industrial progress of mankind is based on power, power for industrial plants, machines, heating and lighting system, transport. In fact, one can hardly find a sphere where power is not required.

At present most of the power required of obtained mainly, from two sources: from burning of fossil fuels and producing electricity by means of generators.

The energy of the Sun, which is being used in various ways, represents a practically unlimited source.

Using atomic fuel for the production of electricity is highly promising. It is a well-known fact, that one pound of uranium contains as much energy as there million pounds of coal, such cheap power can be provided wherever it is required. However, the efficiency reached in generating power from atomic fuel is not high, namely forty per cent.

No wonder, therefore, the scientists all over the world are doing their best to find more efficient ways of generating electricity directly from the fuel (without using intermediate cycles). They already succeeded developing some processes, which are much more efficient, as high as eighty per cent, and in creating a number of devices capable of giving a higher efficiency. Scientists are hard at work trying to solve all these and many other problems.(by A. Kovalenko)
