Kanał Elbląski: statki płyną po LĄDZIE po pochylniach. Jak?

A ship weighing several dozen tons climbs to the height of a nearly 100-meter-high skyscraper—and it's powered by no engine. Not steam, electricity, or exhaust fumes. Instead of floating, it glides across grass, along a green slope, among meadows and fields where water has no right to reach. How is it even possible for a ship to travel on land, and without a single engine? The Elbląg Canal has been asking engineers around the world this very question for over a century and a half—because it's the only such operating structure on Earth. Behind its construction lies a 100-meter wall that for generations seemed insurmountable, an idea brought from overseas, and a brilliant reversal of the problem that no one else in Europe dared to attempt. This is the story of a waterway through reeds and bird sanctuaries, of a sunken fleet, and a miracle that almost vanished into the silence of oblivion. Let's delve beneath the surface of this mystery and discover how man has forced water to carry ships uphill. The video materials used in this film come from the following channels: @Lecewmiasto
