to save the planet. and taking the battle for a cleaner climate into outer space. can the final frontier help us breathe easier down here on earth? wherever you rejoining me from around the world. once again, a big hello and a warm welcome to the show. you know, the climate emergency, it s not new. but as global leaders gather for this year s united nations climate change conference or known as cop 28, it s in dubai. we wanted to see how business and innovators are tackling the climate emergency. so we ve sent our crews and reporters around the world to find the cutting edge technology that could literally save the planet. we begin on a set of islands off the far north of scotland where theo leggett is exploring under the sea. bleak but beautiful. this is the pentland firth, the channel that runs between the north coast of scotland and the orkney islands. it s an area well known for vicious winds and ripping tides and that makes it the perfect location for developing new form
that runs between the north coast of scotland and the oakney islands. it s an area well known for vicious winds and ripping tides. and that makes it the perfect location for developing new forms of clean energy. this narrow strip of water experiences tremendous title forces every single day, in fact they are some of the fastest tides in the world, and that means that there a tremendous reserve of energy if you can tap into it. and that s what s going on just over there, off the island of stroma. beneath the surface, are for gigantic turbines are four gigantic turbines which are generating electricity, right here. the power generated in the murky waters of the first by the power generated in the murky waters of the firth by these vast turbines is already being sold to the national grid. the past five years has been spent testing the technology, and the company behind them says it s ready for a major expansion. so fraser, tell me what we ve got here. we have a 150 tonne, 1.5 mw
