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 fuels. let s 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 there s electric. but although batteries are getting far more efficient, the size that you d
in the original frame, we would be able to fly about 19 passengers. it looks like a lot of kit in there. how would you fit in 19 people? yeah, so in the retrofitted configuration, it will be about a dozen people. daniela is one of the engineers working on the engine. actually, the fuel cells are this one. the power is created in these small layers. so you have to build up your layers to create the power to take off an aircraft. this engine could almost provide enough power to get you from london to glasgow, but not quite. if you wanted to scale it up for international flights, would you just make the same thing bigger or is it a totally different exercise? it is scalable until a certain power, but then we ll have to change technology. getting this high power density system that will allow to have a lot of power but minimal weight to be integrated on an aircraft is really a challenge. and that probably means completely redesigning the plane. everything will be shrunk. some par
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

the new york post spoke to her lawyer joel bennet. he says, quote, it is just frustrating that herman cain is going around bad-mouthing the two complainants and my client is blocked by an agreement. although bennet told the post he couldn t remember the accused was herman cain and said it was settled quickly by fax and phone and herman cain recounted what startss like a drawn-out claim. i do recall that she was asking for a large sum of money. i don t remember what that sum of money was but as the review of this moved forward, that sum of money negotiate my attorney negotiating with her attorney got less and less and less her bauer her attorney figured out she didn t a valid claim. the lawyer have differing accounts of reaching a settlement with this woman or talking about two different complaints. remember, when politico broke the story on the weekend the lead is two women complained of inappropriate behavior by cain. herman cain seems to remember one complaint and o
