A Little Wisdom Helps You Become Smarter !In the video, A worker turns a valve wheel (like a steering wheel) directly mounted on a large pipe. This pipe connects a reservoir to a concrete water channel. When the valve opens, water rushes out of the pipe into the channel. The water then flows several kilometers downstream to generate electricity. This system has provided reliable power since the 1980s.
