Now theres a global race to get clean aviation off the ground. And some Companies Think theyre 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. Weve 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 thats 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 coming up with new fuels. Lets take a look at some of the options. There are biofuels, which are made out of things like plants or vegetable oils, but they still produce some harmful emissions. Then theres electric. But although batteries are getting far more efficient, the size that youd need to power a pass
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 coming up with new

you ready? so do the calibration again. safiya is using the eye gaze application to play different types of games using eye movements. you re a better driverthan i am. afterwards, i asked her what she thought. so what s it like, playing games this way with this new software? speaking software: it is good. it helps me to focus. and is it easy to use? yes, it is easy. it helps me experience every action of the game. and is it better than playing other ways you might have done before? yes. i ve only tried the nintendo wii. this new controller helps me play better. that s the young ones suitably impressed. over at ucl, the students working on different elements of motion input were keen for someone slightly less youthful to have a go and see how it works using bodypoint. first up, everyone s favourite
