Text 2а. Harnessing solar energy

The experiments on solar cells gave the possibility to collect enough data to predict the possible performance of solar stations. These experiments have led to the building of a solar furnace developing temperatures of 3,000°C in a sunray focal point. Electricity generated by such an installation costs less than that generated by a steam power-station.

The solar stations in the Kara-Kum desert will become producers of cheap electricity in the near future. The amount of solar energy per square meter here is equal to the energy generated by burning 200 kg of high quality coal.

Power cells of the size of a matchbox have been developed to convert solar energy into electricity. Such cells can accumulate sufficient energy in one bright day to power a large transistor radio for ten days.

Assignment 15. Point out which of the sentences contains the information from Text 2A.

1) It is quite possible that some day coal and other fuel may be replaced by atomic energy.

2. Solar stations will produce cheap electric energy in the near future.

3) The experiments on atmospheric electricity were made by many outstanding scientists.
