this is what the sensors record because particular matter cannot be seen by the naked eye. i just. remember these are they could cause this these circles show current conditions in virtual reality and . the stuff of course when it hits my monitor if i go over to the other monitor i can see that same section on a bigger map. pushed when jets vanished in virtual reality and if i now put on my view your visor it puts me right in the middle of the particularly matter. over at the fuck up a tree they've been working on green projects for more than 30 years now and are now building sensors for particulate matter. the aim is to increase public awareness of air pollution. and it's a bit of a typo for you will see people getting involved similarly to wikipedia and that

data being made available to everyone. this innocuous looking sensor has now been replicated hundreds of times by people in berlin the hope is that the data can be used to make information about air pollution public and not just in the german capital. not air pollution has many chefs in media when you do come not only from vehicles. power plants but also from something as basic and ubiquitous as a cooking store for millions of people the daily chore of cooking poses a real danger a serious storm is providing the much needed. here in this cramped kitchen. is making a family of 6 she's using a traditional cooking stall a junior which blows out clouds of smoke. on the markets

of youth with the use of mud still we don't have an alternative look at the markets people have cooked with to last for generations their business if you don't have the money to buy better fuel. if we did we might be able to use another kind of story like i guess these. old 77 percent of households still use 5 cheap and easy to access liquid petroleum gas . is a privilege reserved for the. with open fire means. to spend a hot stove breathing in kerosene fumes and smoke from. collecting boat is a burden on the environment and a strenuous task for them and. each

year almost half a 1000000 people die prematurely from illness attributed to household air pollution in india. traditional stoves are the main source of the problem and vim and young children are the versed affected. these stoves are so inefficient that the vest up to 90 percent of the unity generated and require up to one 3rd of the family's income for a few that also responsible for a quarter of the world's black carbon emissions. a social enterprise has been working to tackle the problem of energy poverty and for all for india has developed an efficient thermal store it uses voted but around 60 percent less than a traditional stove it is also designed to significantly cut the smoke and docks

the commissions that are responsible for health problems. the organization distributes stoves to do households in india and elsewhere in the wood at a subsidized rate my lunch out again when they set up but now. that you have had the project for 3 years and vietnam seen its benefits. incentives improving they save a lot of time in the news in this type of life and i love that. and benefit is stacked in even a job prone area and fewer trees are being chopped down. this has a huge positive impact there more thought of whether the. who lives in the village neighboring shrug or made the switch with the help of a community led micro-finance group many like her can't afford even the subsidized cost of 30 euros and need financial help.

might it is all that there is there was that one we used to need more than 10 kilos of wood now we need only 5 and cooking takes half the time it used to take out is this lot of they have to do like there's a lot of. still struggles with health issues resulting from a smoke inhalation she can't afford to buy one of the new stewards. that borders are covered by ice burn their water continuously the older i get the less i can say i have frequent bouts of cord and cough on my neck and back hard from the piles of food i have to carry there was any. like sharda some 700000000 people in india continue to rely on solid fuels and traditional cookstove smoking and poverty remains a major problem. evolution and killer

traffic are almost synonymous in urban societies around the what that are many projects underway to tackle this problem and eliminate it from day to day life you need just capital jakarta like all major cities in the world is no stranger to the effects of increasing traffic congestion and the air pollution it gives rise to an expert in the city is experimenting with hydrogen as fuel for an emission free model of transportation. justin. the major problem faced by big cities around the world including jakarta it's typically caused by the lack of a good public transit system with a growing number of vehicles on the street jakarta's air quality is going from bad to worse. energy based on hydrogen is one of the solutions for creating a transportation system with less noise and fewer emissions.

professor any analysts yani doing is among the leading experts in this field since 1988 she has been conducting research in alternative energy with hydrogen fuel cells. of the drug and we did research on producing hydrogen. from waste or from methanol but the easiest way is to get it from water. and here the end product is again water that we can use the electrolysis method to produce water from water the hydrogen goes into a fuel cell becomes water to electricity this is current energy storage. the 2nd way is to source it from natural gas as is done in the fertilizer industry or thermal power stations because it's cheaper. the 3rd method is to get hydrogen from renewable materials. fuel cells work in a similar style to batteries the only difference is that while producing energy

fuel cells continue to work as long as a fuel source is available they can also contain 10 times more energy than a lithium battery. i'm getting so bad about that they can be used for transport haitian. at home. as a backup power for machinery. or for energy storage storage and. one application is this motor with a 500 watt passively the fuel cell technology developed by professor any a list jani doing. requires an average of one leader of hydrogen gas to produce one kilowatt hour of energy the production costs however are still far higher than with fossil fuel based energy solutions here at the agency for the assessment of application of technology any honesty i mean do we try to enhance hydrogen production to be more efficient so one of the breakthroughs in the fuel cell field

is discovering a new catalyst in electricity producing generators for the future the scientist is thinking of an overall energy concept for the city. and the answer i had. my dream is to build a hydrogen city in indonesia it will have a hydrogen based economy. so if we apply it to transportation it will mean an environmentally friendly satins that that's what i think. and in people's homes it will have 0 net emissions 0 and. that i hope we can do this in indonesia said. the professor will continue her research on creating hydrogen fuel effectively to create transportation that is comfortable and without pollution or emissions the more efficient the fuel cell is the more likely it will be possible to use it on a broader scale. if you allow it the benefits that nature

provides us with our enormous i hope of these shall give you the information and inspiration to work in sync with nature if you haven't already started to do so i'll see you again next week from all of us in between. the. children to come to see. one giant problem i mean

a big no no to see a picture you. immediately facing a fuel economy clock how will climate change affect us and our children lobby. for. dot com slash water.
