aviation innovation. this week, lara looks at the elemental solution to cleaning up carbon emissions from aircraft. we travel to the remote faroe islands to look at the latest ways to harness tidal energy. it s sort of like kitesurfing, but on the water. if it moves, it s a controller paul s en route towards more accessible games. if ijust raise my eyebrows, i m making the carjump. and we look at how generative technology could revolutionise the moviegoing experience. it can make approximately 52 quintillion versions of the film. about 100,000 flights jet around the world every day. flying accounts for 2.5% of all carbon emissions. now, that might not sound like much, but if aviation was a country, it would be among the top ten most polluting nations in the world, and its impact is expected to rise. now, there s a global race to get clean aviation off the ground. and some companies think they re close to cracking it. pretty soon, passengers will be flying in zero emission a
of the film. about 100,000 flights jet around the world every day. flying accounts for 2.5% of all carbon emissions. now, that might not sound like much, but if aviation was a country, it would be among the top ten most polluting nations in the world, and its impact is expected to rise. now there s a global race to get clean aviation off the ground. and some companies think they re close to cracking it. pretty soon, passengers will be flying in zero emission aircraft. but how did we get here? archive: the new machine is called, optimistically, - the flyer. we ve come a long way since the wright brothers first flight in 1903. that day, they lifted the world into a new dimension. then we achieved bigger, faster planes. great, but that s also how we ended up with all these emissions. jet engines burn kerosene, which releases carbon dioxide, one of the main greenhouse gases causing climate change. the industry faces an enormous challenge to clean up its act, and that means comin
Generating electricity using the current that flows through this stretch of water. Weighing 28 tonnes and with a 12 metre wingspan, the newest dragon can deliver 1. 2 megawatts of power. Its sort of like kitesurfing, but underwater. So we tether it off to the sea floor, foundation on the sea floor, and then it flies in a figure of eight. As underwater Currents Flow by, the kites wings generate a hydrodynamic lift force, spinning the turbine and generating electricity. This design s very different to other types of tidal technology. So whats the advantage of a design like this one . We can install and operate and produce power in low flow currents with lightweight machines. Although it looks big to the eye, this is actually a very small tidal turbine. Weve designed the system as such to be maintenance friendly you simplyjust tow them in,

Weve designed the system as such to be maintenance friendly you simplyjust tow them in, replace modules and then put them back in. Weve also, over the years, removed more and more components from the system and fit them onshore instead. The less old components you have that could become damaged, its easier to access it and its
as such to be maintenance friendly you simplyjust tow them in, replace modules and then put them back in. we ve also, over the years, removed more and more components from the system and fit them onshore instead. the less old components you have that could become damaged, it s easier to access it and it s much cheaper also. it s the gravitational pull of the moon, and to some extent the sun, which gives the tides their rhythm. and unlike wind, solar or hydro, tidal power isn t reliant on weather. while tidal barrages have been around for decades, their cost and the ecological impact has been a barrier. now, from the scottish islands through to canada, a new generation of tech firms have introduced tidal stream turbines. 0cean energy is still largely untapped, so what are the barriers that have prevented it from taking off?
