Why can't we use energy from the waves of the sea to create all the electricity that we need? Listener Michael in Kingston, Jamaica wants to know. Living on a Caribbean island means he’s never far from the might of the ocean – so could it power his house?

Presenter Greg Foot heads to one of the world’s leading wave energy test locations, the coast of Cornwall in the UK, to find out. There, he witnesses the challenges of the marine environment, from metre high waves in a giant indoor test tank to being buffeted on a beach where a 25km cable runs beneath his feet to a grid-connected offshore test site. And find out if Greg’s plan to feel the power of the waves first-hand on a research boat works out – in the middle of winter, in the northern hemisphere.
