The power of the oceans' tides is the last great untapped energy source on Earth; from sub-sea kites to floating platforms, teams of engineers race to perfect the technology to harness the vast flows of water.

Shipping companies and engineers create remarkable new machines to make their industry greener, using a resource that has moved man across the world's oceans for thousands of years: wind.

The sun is the biggest source of energy in the solar system; innovators search for new ways to capture more of the sun's power and make it available through the night, everywhere.

When water unleashes its rage upon the planet, it becomes the ultimate bringer of death; whether it's from rain washing over the ground, rivers bursting their banks, or failed efforts to stem the flow, flooding is as inevitable as it is unstoppable.

Bridges and tunnels revolutionized transportation-but when they fail, tragedy follows. This episode explores the world's worst collapses and fires, including a tunnel blaze in the Alps so intense it fused 20 cars together. While bridge failures send vehicles plummeting into water or ground below, tunnel fires turn confined spaces into infernos. Why do these disasters happen, and what can be done t

Hurricanes, typhoons and cyclones are all the same thing with different names, but what they also have in common is their destructive power.

Earthquakes occur when tectonic plates suddenly shift and shock waves shake the Earth's surface; they occur along fault lines -- the most active being the Ring of Fire in the Pacific Ocean and the San Andreas Fault on the American West Coast.

Volcanoes created more than 80% of our planet's surface, but explosive eruptions can be deadly; a journey under the earth to discover why volcanoes are so dangerous.

Tornadoes are violent, rotating columns of air that can level buildings, their unpredictability makes them even more destructive; a look at how tornadoes form and if they can be stopped.

From 200 million years ago, when Europe moved toward North Africa, to the age of Columbus.

Linking prehistoric forests to the Industrial Revolution and the rise of modern warfare.

Part 1/3. Thanks to Rollo the Walker, Normandy became one of the most powerful principalities of the kingdom of France; he is one of the most terrible Viking warriors in history and his adventure began 1200 years ago, at the mouth of the Seine.

Part 2/3. At the head of Normandy, the descendants of Rollo built a powerful and organized duchy in Europe; but in 1035, the crown was inherited by an 8-year-old bastard child, William the Conqueror.

In the 12th century, Normandy was at its peak; thanks to the efforts of the legendary Norman duke, Richard the Lionheart, it controlled almost half of the Frankish kingdom and England and invaded Ireland, Sicily and Spain.
