print culture between here and there challenging for in. the 2nd year was worth it for me to come to germany. and got my license to work as a swimming instructor. for an hour or 2 children not to dance just random stuff just to see. your story take part charity on info migrants dot net. is a spectacular job of lighting up our planet but when it comes to running out 24 hour a day cities manmade electric light is

a must and although costs and astronomical $100000000000.00 euros a year there are new types of lights and lasers. that have the potential to reduce those costs opening all sorts of new business opportunities 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 a 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 duck 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. i had one bad day i said to you.

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 a solar technicians. that come from mexico. kenya. and indonesia. the program last 6 months and every school day begins with accessories. male bandung who 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 all right and pressing fabric in the dark all by candlelight can

also be dangerous. 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. with. the teachers and. you know 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 any time where a solar electricity is reliable the sun god shines for everybody and doesn't care 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. how would. you know why you know why you know power of. 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 to mexico then she'll have to work out how to use the new skills and knowledge she quoted in india. i have no idea what i'll be able to earn now but what matters is that i've learnt so much. that the people at home will see that i can do good work. it's been quite a sacrifice to come here to learn something new and then i want my book was to close is financed by the indian government and the united nations and a number of businesses. graduate and head for home have plenty to tell their communities about their adventures in india. and 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 so the market for high efficiency labs will hit a global $46000000000.00 and the world leader in the sector is philips developers of the dutch giant are 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 greenhouses lit by the lamps even in buildings without sunlight. any daylight bulbs provide illumination by day and night and the plants compete harvested at any time of the year. ends up 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 a spinoff of dutch technology giant philips so far the company has equipped around a 1000 greenhouses with lighting systems we have $4.00 inside so it's red it's blue it's white then it's already had a far it is typically pretty are known 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 fell you all for strawberry short as 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 company can kill apes 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 has less sunlight than those in. pain. market is growing sugar fast if you look at the different reports that are out in the market you see real trend that 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 fairly daylight's and that was the biggest project we did today. another customer that has bought the lighting systems

is the dutch tomato farm vin pater's it's greenhouses measure 16 hecht has an area amounting to something like 20 soccer pictures. the crops are aluminum 2 by magenta l.e.d. light from below and from above by high intensity high pressure sodium or h.p. has lamps the company has invested millions the tomato vines grow to an amazing height of 6 metres 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 in the middle of the crop. research. shows. the must be about 80 centimeters to one metre. below the top of the plant because the top of the plant is factored by. lightning and daylight. and one metre below

the effect of the day. is gone. tomatoes are perishable they can be easily transported in container ships from far away countries. 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. it's nice. very sweet. but what's important is that the taste. stays in your mouth for a long or a time so this not only the place is gone immediately. you get a certain bite of the tomato. of course lighting the plants all year around 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 a major disadvantage of this kind of farming the energy cost of producing artificial sunlight outdoor farmers kept 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 show 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 incandescent light bulb made by the big players and the industry. germany's. philips and the netherlands and g.e.

in 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 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 hours 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 by the internet. the 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 wiping out the saving effect. plants and animals will suffer from the loss of darkness light 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 nowhere 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 anywhere and they can transmit information at a much higher rate than traditional wires or even fiber optic broadband cables a german startup is already sending data and information around the globe by laser

big. the highly concentrated light beams can be used to transport information at extremely high speeds. my narrative is a munich based on top that has developed ground stations for wireless data transmission via laser beam. internet superhighway in the sky an estimated 3 to 4000000000 people around the globe still have no high speed internet access my narrative is people in remote regions sending their data request from their device to a ground station operated by the company from there it's relayed fire laser light to the next link in the airplanes high altitude balloon and satellites after

reaching the next relay point the request continues to question in whatever part of the world that may be and from there the laser returns the desired data movies for example. they can dispatch a great deal of energy to communication the energy density is very high which is why free space optical communication works over extremely long distances with very lightweight devices. online giants such as google have already conducted successful tests. with the promise of high speed internet especially in areas that have no coverage plan would require. and that's where technology could come in and.

how exactly is. data transferred as with any binary computer code a one stands for electrical signal own and 0 for signal data is converted and then dispatched the laser works with the same principle an active laser beam means one while in action means the connectivity provided here is 10 gigabits 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 that space where they know us here. here the team of testing a rocket that will transport mine eric 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 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 mine eric is still waiting for the big breakthrough. with current technology reabsorption is simply too great there are other options from on the for example cloud cover diversity where you look for a ground station that is excessive bill and then have the laser sent past the bad weather. mine eric hopes that within a year telecoms companies will start setting up online networks above the clouds that use than laser technology and 5 or 10 years from now perhaps there really will be high speed internet access. what about getting through life

without light or better said 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. despite that they've managed to overcome employer prejudices themselves out successful careers. let me know when it starts to hurt. can you still speak. and breathed. period i have retinitis pigmentosa it's a genetic disorder and causes tunnel vision my eyesight was quite good until i was 30 or 35 i could still ride my bike. on the far. right 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 you verify you can cover up a lot you become a champion in covering it up of course i have trained my coworkers to never put things in the wrong place. i get so mad if i have to spend hours hunting for something or if i reach for it and it's not where is meant to be and i have to start looking for it. on my parents always supported me they never said you won't be able to do that if it weren't for my 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 lynn is very noisy very crowded and people just leech other a lot it's

a challenge. i 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 they shake your hand. i'm not a living light detector but i am pretty sensitive to what people are telling me whether it's true or whether they're lying. on the phone if you can't imagine a blind person can climb a flight of stands you won't believe that it visually impaired person can hold their own in the workplace. i've been blind since birth but 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. on.

the braille display is mainly for corrections. but for the most part i use the voice synthesizer to check if a word is written wrong. that's called lake. view. there's a gap. right this is corrina you can read braille already. in the 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. in on the app will tell me. what. it costs to get the bus is just arriving now you know what

that's done but that can be recognized by the app. it says the next one is delayed coming in 10 minutes it doesn't show the one that's just come in so i got on the. style of in town because there's good public transport that lets me get around. that 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 it's not as easy as that for some people they count sheep to get to sleep well if you hold off thank you hit the town and he's clearly not alone in it sometimes it feels like the whole city has insomnia so what's his advice make the most of your nights.

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 can be lots of fun the lights the collars the atmosphere late at night it's inspiring better than counting sheep. to some fantastic sights i had a fabulous night just think i knew. and he slept through it. flopped rose consciously burn your bad 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 life even after you've just side whether that's a good or bad thing time to turn out the lights in the studio hey thanks for joining us i'm 8 he said.

my job join me for me into the. post supposedly and now i'm going to be a fictional agent but as affectionately as you can. slap the mirror putin in the middle of his election campaign in the year 2000 a documentary was filmed for russian television but director vitali munson captured much more it was to turn the camera back on the moon of course. the film secretly chronicled a power grab actually. everything was precisely plan structure. featuring tom supporting roles to the front of the show. featuring a lead role like you've never seen before let me be clear with you. good manners that i'm your average to the ends justify the means. to
