Hydroelectric power generation involves arranging impeller at slope of barrier, with slope located between upstream side and downstream side of water stream

摘要

The method involves arranging an impeller (3) at the slope (1.1) of a barrier (1), with slope located between upstream side (2.1) and downstream side (2.2) of water stream (2). The impeller is rotatable about an axis horizontal, near horizontal, or transverse to the water stream.
