These Are the Most EXTREME Tides on Earth

Why It Matters

If engineers can build durable, ecology-friendly tidal devices for the Bay of Fundy, the predictable and massive energy resource could provide reliable renewable power and serve as a model for tidal projects worldwide.

Summary

The video profiles the Bay of Fundy, where a unique combination of deep, narrowing bay geometry and a natural seiche amplifies Atlantic tides to move roughly 160 billion tons of water and raise the shoreline by over 50 feet—the largest tidal range on Earth. That resonance funnels enormous potential energy that could theoretically power hundreds of thousands of homes, and its twice-daily predictability makes it an attractive renewable resource. Practical attempts to harvest this energy with turbines have repeatedly failed so far because of the bay’s chaotic flows and harsh conditions. Researchers remain optimistic but emphasize any technology must avoid disrupting the bay’s distinctive ecosystems.

Original Description

Inside Canada’s Bay of Fundy, 160 BILLION tons of water rush in and out daily, creating the most extreme tides on Earth. Scientists now think this force could help power our future.
