yes, absolutely. according to matthieu, the initial results are promising, with daily readings of pm 2.5 around the village as much as halved. there is some wind, but. but there are still some limits to its effectiveness. this is only local. the first priority is to decrease the emission of pollution, of course. if this summer s trials are a success, matthieu hopes these devices will become a common sight in busy parts of paris. ..transforming the very air we breathe. here we go! my next stop is the parisian
it is part of the olympics to boost innovation. is this a training ground for you to see how this works and where it can be used? absolutely. according to matthieu, the initial results are promising, with daily readings of pm 2.5 around the village as much as halved. there is some wind, but. but there are still some limits to its effectiveness. this is only local. the first priority is to decrease the emission of pollution, of course. if this summer s trials are a success, matthieu hopes these devices will become a common sight in busy parts of paris. ..transforming the very air we breathe here we go! my next stop is the parisian
this is matthieu gobbi, and this is one of his company s giant helium balloons. here at andre citroen park, they carry up to 1,000 tourists a day. we re going to fly and make some readings. is it safe? yeah, of course it s safe. the balloon is going up and it is connected to the ground with a cable, actioned by a winch. so perfectly safe, especially with this beautiful weather. ok, so we can come down again in the same spot, no problem? hopefully. that is music to my ears. can you help me up here, please? is that 0k? yeah, sure. thank you, matthieu. yep, you re welcome. you re ready for takeoff? i am as ready as i ll ever be. he e y! are you sure that winch is going to hold you? i guess so. yeah, we guess so, yeah. matthieu laughs. ifeel like phileas fogg. you are.
yeah. and p0p: p0p: p0p: p0p- easy. yeah. so he s invited me to his office to show me the designs for their new experimental air purifiers. so this is where the magic happens, is it? yes, absolutely. wow! you see how it works? so there is a fan in the centre to suck the air in. and in this module we have the electric field, you know, to attract the dust, like a magnet. yeah. the air is cleaned and flows out in the centre. yeah. looks like a spaceship. they won a tender to install some prototypes in the new olympic village. according to matthieu, the initial results
so is this a good day for pollution? today is a good visibility. pollution is pretty low. because. . .yesterday was very windy. but most of the time in spring or summer, uh, the particles get really high. in paris and in many other european cities, the air quality falls below the standards set by the world health organization. and even on a clear day like today, the balloon s instruments find unsafe levels of pm 2.5, the tiny particles of pollution given off by burning fuel in vehicles or buildings. it s been linked to a range of serious health conditions. welcome to the office. thank you very much. but matthieu thinks he has a solution to improving the air quality in built up areas. so there s a bar here?
