strengthen states of emergency 6 into chaos. turned into 6. camps the people threaten steel. 1979. that created today's more troops december 23rd w. does a spectacular job of lighting up our planet but when it comes to running out 24 hour a day cities manmade electric lighting is a must at all the costs and astronomical $100000000000.00 euros a year there are new times and lights and lasers. that have the potential to reduce
1:31 am
those costs opening all sorts of new business opportunities a let there be light it's something many of us take for granted but the more we light up our world the quicker we lose sight of others although as we just saw a large stretches of the earth's surface and now with the related old night long there are still many places that don't have electricity and can't afford it that doesn't have to mean being left in the dock he's next women have traveled from all over the world to india to learn how to build solar systems in half a year they'll return to their villages bearing the gift of light. god wanted me to go to india for writing to hear about the i said to you. that i'm doing this for my children. these 3 women had never traveled far from home before and now they're in india they come to train
1:32 am
a seller technicians. that come from mexico. and indonesia. the program last 6 months and every school day begins with exercise that mailman don't do was sent by her village in kenya where they don't have any electricity. they're eagerly awaiting to reach. a light to my comment we all know that darkness is not the best way so bringing light to the community is a horn big achievement. at the moment after sunset in her village no one can sew or write and pressing fabric in the dark all by candlelight can also be dangerous.
1:33 am
during the course the women learn to install and repair solar panels and to build solar lighting equipment. the practice and practice until it's all routine. you mean it comes from west timor in indonesia. without light my children can't do their homework and when it gets dark they have to go to sleep when i get home we're going to have solar lamps in the hospital. with. the teachers and. oh you still believe in the military has been working here since 2003 teaching women from all over the world. to. electricity from the grid can go out at any time where a solar electricity is reliable the sun god shines for everybody and doesn't care
1:34 am
if you're rich or poor. if you can't pay your electricity bill power is cut off. with solar lamps you buy them once and then you can relax. there is similar programs in africa. here they also sell solar lighting systems. as well as teaching women how to make money with solar energy. to go to around the villages and make their living by selling the equipment. or you know why you know why you know in power for. 3 and a half 1000 so-called solar sisters have sold almost a quarter of a 1000000 solar lamps street light to almost one and a half 1000000 people. on the course is isabel more humane as we'll head back home
1:35 am
to mexico eventually have to work out how to use the new skills and knowledge she quiet in india. and media i have no idea what i'll be able to earn now but what matters is that i've learnt so much. people at home will see that i can do good work. it's been quite a sacrifice to come here to learn something new what happened that i want. to close is financed by the indian government and the united nations and a number of businesses wants to graduate and head for home have plenty to tell their communities about their adventures in india. that you. well like doesn't just allow you to continue working after the sun goes down the advent of l.e.d.s. has also washed it in a new age in a wide range of fields soon the market for high efficiency labs will hit
1:36 am
a global $46000000000.00 and the world leader in the sector is philips develop as a child to now focusing on new applications in agriculture like bringing high tech farms into the heart of cities. the earth is home to 7750000000 people the majority live in cities green spaces are shrinking. how viable an option is been farming for example green houses lit by lamps even in buildings without sunlight. any day light bulbs provide illumination by day and night and the plants compete harvested at any time of the here any deans are becoming standard lighting solutions in greenhouses they have long been undergoing testing here in the netherlands in the laboratory of a signify it's europe's biggest lighting manufacturer and
1:37 am
a spinoff of dutch technology giant philips so far the company has equipped around a 1000 greenhouses with the lighting systems we have for callers inside so it's red it's blue it's white then it's far out ahead of far and it's typically pretty on unknown to us because it's outside of our i sense david baker. vertical indoor farming is a market with huge potential. and the l.e.d. lights help to guarantee predictable and controllable harvests. and so what you see over here is a dynamic light fixture that can change in color and by changing the color during the trial or just before the end of so just before harvesting we can for example influence the bricks value all for strawberry so that's the sweetness of the strawberry but also make it a little bit more hardy or let's say show that it's better to transport. the
1:38 am
company can kill a to the particular light fixture its customers need and savings can be achieved by just using red and blue light which produces the magenta color here. the mix depends on the plants and the ambient light greenhouses in siberia for example have less sunlight than those in. spain. so the market is growing super fast if you look at the different reports that are out in the market you see real trend that the lights are becoming more interesting also it's not because they don't make money that companies like are growing fast in russia would by $25.00 factors and $25.00 factors it's around 400 kilometers of the lights and that was the biggest project we did to date. another customer that has bought the lighting systems is the dutch tomato farm is in pater's it's greenhouses measure 16 hecht tears an area amounting to something like 20 soccer pictures. the crops are aluminum to buy magenta any
1:39 am
delight from below and from above by high intensity high pressure sodium h.p. has lamps the company has invested millions the tomato vines grow to an amazing height of 6 meters the growers need lifts to reach the tops using the l.e.d. lights the company can achieve larger and more constant harvests than without the lighting. we have the positioning of the the in the middle of the crop. research. must be about 80 centimeters to one metre. below the top of the plant because the top of the plant affected by. lightning and daylight. and one metre below the effect of the day. is gone. tomatoes are perishable big can be easily transported in container ships from far away countries
1:40 am
. but they can be easily grown in greenhouses. thanks to the l.e.d. lights they can harvest more 20 tons per week even in the middle of winter. this is very sweet. but what's important is that the taste. stays in your mouth for a longer time so it's not only the taste is gone immediately. to the taste certain bites of the tomato. of course lighting the plants all year round uses up lots of energy as does the heating via the pipes that run between the plants on the floor to generate it the company maintains a gas fired power plant and that highlights
1:41 am
a major disadvantage of this kind of farming and the energy cost of producing artificial sunlight outdoor farmers at the sun for free. in the 19th century gas lanterns still lit up our streets then thomas alva edison came up with the 1st commercially viable electric light bulb they didn't last that long logbook showed they only burn for 14 and a half hours the technology for producing light has come a long way since then. this is what lit up the 20th century the good old doesn't light bulb made by the big players and the industry. germany's. philips and the netherlands and g.e. and the us controlled 80 percent of the market later a competition emerged in the form of fluorescent tubes allergan lamps and other energy saving lighting devices since 2012 sales of conventional light bulbs have
1:42 am
been phased out and the e.u. . the leading light of the 21st century. the only d. short for light emitting diode it converts around 80 percent of the electricity it uses into light in contrast to incandescent light bulbs with just 5 percent efficiency. it lasts longer than all previous models to supposedly up to $100000.00 and l.e.d.s. already have a market share of 50 percent. of the smart homes of the future lights will be turned on and off focused via the internet. very light wherever whenever and in whatever color you want. or automated intelligently for efficient lighting and factories or businesses. but the problem is that if everyone thinks they're saving money with efficient lighting they'll use more of it
1:43 am
wiping out the saving effect. plants and animals will suffer from the loss of darkness pollution will worsen new lighting technology is keeping the world permanently lit up for better or for worse. billions of people around the world are left in the dark when it comes to the internet many remote regions have no access to cable networks and setting up the infrastructure to get everybody. online would be a mammoth task so why not think outside the box laces can reach anyway and they can transmit information at a much higher rate than traditional wires or even fiber optic broadband cables a german stand up is already sending data and information around the globe by lays a big.
1:44 am
the highly concentrated light beams can be used to transport information at extremely high speeds. mine eric is a munich based on top but has developed ground stations for wireless data transmission via a beam. internet superhighway and. an estimated 3 to 4000000000 people around the globe still have no high speed internet access my naresh people in remote regions sending their data request from their device to a ground station operated by the company from that it's relayed fire laser light to the next link in the airplane's high altitude balloon and satellites after reaching the next relay point the request continues to question and whatever part of the world that may be and from there the laser returns the desired data movies
1:45 am
for example. great deal of communication the energy density is very high which is why free space optical communication works extremely long distances with very lightweight devices. such as. conducted successful tests. with the promise of high speed internet especially in areas that have no coverage plan would require. and that. technology could come in. how exactly is. the data transfer as with any binary computer code a one stands for electrical signal own and 0 for signal elf data is converted and
1:46 am
then dispatched the laser works with the same principle and active laser been means one while in action. the connectivity provided here is 10 gigabytes per 2nd in 4 seconds that's an entire feature film. to make because expect the technology to work in outer space too with satellites distributing the laser light that currently testing components for the space webbing us here was. testing a rocket that will transport mine aren't laser into outer space. your 1st. of course we try to qualify commercial components with this area of deployment and that means finding out whether commercial automotive parts are also suitable and that could lead to cost cutting. their cost and saying. that this new means of
1:47 am
transmission faces low tech barriers that slow it down such as clouds which lasers are unable to penetrate so on that front the team that my nerika is still waiting for the big breakthrough. with current technology reabsorption is simply too great and there are other options on the for example cloud cover diversity where you look for a ground station that is excessive and then have the laser center pass the bad weather . mine eric hopes that within a year telecoms companies will start setting up online networks above the clouds that use their laser technology and 5 or 10 years from now perhaps there really will be high speed internet access for all. what about getting through life without light or without the sense of sight just getting to work would be a challenge but in germany only a quarter of all people find jobs. and i met 3 women who can't see it.
1:48 am
despite that they've managed to overcome employer prejudices and carve themselves out successful careers. let me know when it starts to hurt. can you still speak. and grieve. period i have retinitis pigmentosa is a genetic disorder and causes tunnel vision my eyesight was quite good until i was 30 or 35 i could still ride my bike. a very normal fark of. most of my patients don't even know. when i tell them i'm legally blind they say they don't believe me. that was a quick. one can verify if it is if you can cover up a lot you become a champion in covering it up of course i have trained my coworkers to never put
1:49 am
things in the wrong place. i get so mad if i have to spend hours hunting for something if i reach for it and it's not where it's meant to be and i have to start looking for it. i don't know my parents always supported me they never said you won't be able to do that if it wasn't for my eye problems i'd never have met my husband i've always liked to play soccer. i signed up for a soccer workshop for the visually impaired here in berlin and the man who organized it became my husband i still go there and play with my son with a rattle ball. but when it's very noisy very crowded and people just leech other a lot it's a challenge. i
1:50 am
see light and dark and contours here in this hall i can make out the windows and the round lamps that look like bright patches. so i can orient myself quite well. i locate the steps with my stick. i know the courthouse building very well with all its corridors and corners. sighted people often get lost here and can't find their way out without help. but when i was 11 i once went to a lawyers office was amazing so it was clear that i would study law. the figure of justice is always depicted with a blindfold in my case given that i can't see i don't judge people by their exterior because i can't that also means i don't get distracted and remain focused on what people tell me. but that doesn't mean i'm entirely free of preconceptions they're just a bit different blind people might not like the sound of someone's voice or the way
1:51 am
they shake your hand. i'm not a living lie detector but i am pretty sensitive to what people are telling me whether it's true or whether they're lying. on the floor if you can't imagine a blind person can climb a flight of stands you won't believe that visually impaired person can hold their own in the workplace. i've been blind since birth when i say i'm on my way to work people ask if i'm going to a workshop for the blind they should be asking where do you work that just goes to show how many preconceptions there still are in the. braille displays mainly for corrections. but for the most part i use the voice
1:52 am
synthesizer to check if a word is written wrong. that's called leak. you. right this is corrina you can read braille already. in a digital world technology is a blessing and a curse at the same time there are some websites we can use easily but far too many are not accessible. coming. down the app will tell me up front. it's up to the bus is just arriving no. standard that can be recognized by the app . it says the next one is delayed coming in 10 minutes it doesn't show the one
1:53 am
that's just come. gone the smell on. it's been it's no melinda shy live in town because there's good public transport that lets me get around. but if self driving cars ever become available and i can afford one i might consider moving to the country. lights out and off to bed and it's not as easy as that for some people accounting cheap to get to sleep well if you're old enough to think you hit the town and he's clearly not alone in berlin sometimes it feels like the whole city has insomnia so what's his advice make the most of your nights.
1:54 am
i just con sleep it's like this night after night and you can't sleep either. the whole city is awake so many restless so during the streets lost in thought. well since 3 awake anyway we might as well hit the town into the night life into the light. sleep listen to lamb dots of fun the lights the collars the atmosphere late at
1:55 am
night it's inspiring better than counting sheep. for some fantastic sights i had a fabulous night just thinking on. he slept through it i. laughed most consciously burn your bat just go with that. plan it grows around 2 percent brighter every year doesn't sound like much but do the math if things continue at that pace then by the age 2050 will be emitting 50 percent more light leave it up to you just side whether that's
1:56 am

do you know what you used to barbecue your sausages. charcoal of course charcoal also from wood cut illegally in tropical forests and seas findings are truly catastrophic food for him how shocking it can't go on what goes to. show called an environmental disaster why is the trim so lucrative why is it taking so long to find alternatives in 15 minutes of d.w. . even the essential so lacking in this small village in southern iraq
1:58 am
and yet the country is rich. but the huge oil revenues have been seeping out into government officials pockets. in the cities people have taken to the streets to protest. what can teachers and school children in the womb larry and still believe in 3009 d w. i was if you when i arrived here i slept with 6 people in a room. it was hard i was free. i even got white haired. learning the german language help me a lot this gives me and they go but you need to interact with the place you want to
