Dedicated individuals aim to engineer extraordinary machines to change people's lives.

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.

Engineers race to generate vast power from thin air: the wind; one of the world's biggest wind farms is being built in harsh conditions along the coast of England; a Norwegian team works on the world's first floating wind farm.
