The Global Jigsaw is the podcast lifting the language barrier to show you the world through its media.

Radio Tehran.

We were not the international community.

That era has finished.

The Global Jigsaw from the BBC World Service.

Listen now by searching for the explanation, wherever you get your BBC

podcasts. Hello and welcome to Business Daily. I'm Theo Leggett. In this program, we'll be taking a look

at the power of the sea, or rather the power we can get from the sea.

Marine energy from tides and waves has huge potential, but can it ever be cheap and practical?

I'll be exploring the issues and on the way I'll be finding out why you need a strong stomach to maintain a tidal turbine.

It does smell a fish quite badly. It's actually a lot

better than it was a couple of weeks ago. Unfortunately, when we bring it back up, we just have to

clean it off, but then everything inside is really looked after very well. I'll be hearing how

wind and wave power could work together. We see deploying our machines in farms 10 megawatts, 100 megawatts.

And these farms can be combined with offshore wind,

so we can deploy devices interspersed within the offshore wind farm,

maximizing the utility of that space.

And I'll be finding out why a group of rugged islands to the north of Scotland

has become a global laboratory for marine power.

Beautiful but bleak, the Pentland Firth is a strait that lies between the northernmost point of Scotland and the Orkney Islands.

The waters here are treacherous. It's an area well known for vicious winds and ripping tides.

But dangerous and forbidding as it may be, the Pentland Firth is also a potential source of vital clean power.
