About 1/5 part of the energy consumed all over the world, work out on a river plant. It receive, preobrazuja a water incident energy in energy of twirl of turbines which one in turn spins the generator which is working out an electricity. Hydroelectric stations happen very powerful. So, server Itapu on the river Parana on boundary between Brazil and Paraguay advances power до13 000 million in Kw.
Energia of the small rivers 2 in some cases can become a source of electrical power. Was possiblly, for usage of this radiant are indispensable specific conditions (for example, small rivers W heavy current), but in a number of its places where ordinary electrical power supply is unprofitable, minihydroelectric power station installation could decide flock of local problems. Besplotinnye river plants 4 small rivers and rivulets exist already. This two-metre aggregate is not that diverse, as besplotinnaja a river plant power in 0,5 KW. Complete with the secondary generator it will supply with energy a peasant farm or a geological expedition, a distant pasture or small workshop... There would be nearby a rivulet! Rotor installation in diameter of 300 mm and weight only 60 kg is output on a current, pritaplivaetsja on benthic "ski" and ropes is tightened from two shores. Remaining - a trick: the step-up gear spins an automotive alternator of a direct current power of 14 volt, and energy is accumulated. The pre-production model besplotinnoj has successfully proved minihydroelectric power station on small rivers of Mountain Altai.
