As think the researchers of Nizhyn Labs of Scanning Devices (Ukraine) the prospects of subsequent development of hydroelectric power stations are related with the rational use of existing hydrotechnical resources.

Hydroelectric Macropower engineering. The Hydroelectric Macropower Engineering uses for production of electric energy the macroscopic elements of matter, for example, the motion of streams of water, the interactions of these macroscopic elements with other macroscopic elements and their actions on other bodies, without regarding deeply the structure of matter.

The use of macroscopic massive elements for intermediate energy transformation is other sign of Hydroelectric Macropower Engineering. The Mass, as known, is a measure of inertia of body; energy is a measure of his motion.

Failings and limitations of macropower engineering. The Hydroelectric Macropower Engineering has the following failings and limitations:

1.  The Hydroelectric Macropower Systems are the systems of indirect action. They need in intermediate transformation of one type of energy into another.

2.  In construction of the macropower systems the massive mobile elements are used that stipulates their high inertia and the necessity in periodic maintenance during all time of exploitation.

3.  The large hydroelectric macropower stations create considerable ecological problems.

Hydroelectric damless macropower stations.  The prospects of subsequent development of hydroelectric macropower stations are related with the rational use of existing hydrotechnical resources and, accordingly, with implementation of the following measures:

· building of the damless hydroelectric power stations with the semi-submerged and submerged hydro-turbines;

· building of the combined hydroelectric power plants for hydroaccumulation and electrical power production near existing hydrotechnical settings.

· building of the small hydroelectric power stations.

Today the small hydroelectric power stations produce only a negligible quantity (units of percents) in the general volume of world hydraulic electric power. The initial capital investments in small hydroelectric power stations are considerably higher, than into hydroelectric power stations with powerful turbines. The cost of electricity, produced by small hydroelectric power stations, is almost 10 times higher, than that, produced by big hydroelectric power stations. But the small hydroelectric power stations have some important advantages.

At first, small hydroelectric power stations in less degree violate ecological balance of environment.

Secondly, small hydroelectric power stations give the possibility to draw nearer to the remote users the production of electric power and thus to simplify the distributive electric systems.

Thirdly, the small hydroelectric power stations give the possibility to regulate loading of networks days and seasonal.

Those hydroelectric power stations, which are built on existing hydrotechnical settings, are the most effective.
