resolution high. opens up making its initial flirtation. strikes and states of emergency sinks into chaos. the 2nd visit. to the people threatens the old order. 1979. that created today's starts december 23rd w. 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 types of lights and lasers. that have the potential to reduce 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 a related old night long there are still many places that don't have electricity and caught for 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. obviously god wanted me to go to india for writing to hear about the i said to you. i'm doing this for my children. these 3 women have never traveled far from home

before and now they're in india they've come to train a solar technicians. they've come from mexico. kenya. 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. it all and to my comment we all know that darkness is not the best way so bringing light to the community is form big achievement. at the moment after sunset in her village no one can sew all right and cutting fabric in the dark or by candlelight can also be dangerous.

during the course the winning 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. the teachers and. the you will 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 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 me equipment. homes and i want 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 spoke light to almost one and a half 1000000 people. on the course is isabel more humane as we'll head back home to mexico eventually have to work out how to use the new skills and knowledge she quiet in india. i have no idea what i'll be able to earn now but what matters once that 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 in that i want my book. to cases financed by the indian government and the united nations and a number of businesses want to graduate and head for home have plenty to tell their communities about their adventures in india. and you. that. well life 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 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 spaces are shrinking. how viable an option is been farming for example green houses 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 any deane's 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 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 far out at a far out it's 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 off strawberries so that's the sweetness of the

strawberry but also make it a little bit more hardy or let's say so that it's better to transport. the company calculates 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. spain. market is growing super 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 l.e.d. lights and that was the biggest project we did today. another customer that has bought the lighting systems is the dutch tomato farm in pater's it's greenhouses

measure 16 hecht has an area amounting to something like 20 soccer pitches. the crops are alumina to buy magenta l.e.d. light 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 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 is factored by. lightning and daylight. and one meter below the effect of the daylight. is gone. tomatoes are

perishable they can't 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 longer 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 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 logbooks 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 end contestant lightbulb 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 how legend 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 a 50 percent. is the smart homes of the future lights will be turned on and off focused via the internet. the light wherever whenever and in whatever color you want. for automated intelligently for efficient lighting and factories or

businesses. but the problem is that if everyone thinks they're saving money with official lighting they'll use more of it wiping out the saving effect. plants and animals will suffer from the loss of harkness 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 no access to cable networks and setting up the infrastructure to get everybody. the 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 start up is already sending data and information around the globe by lays

a big. the highly concentrated light beams can be used to transport information at extremely high speeds. mine eric is a munich based on top that has developed ground stations for wireless data transmission via a beam. internet superhighway in the sky 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 airplanes high altitude balloon and. after reaching the next relay point the request continues to the in 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. such as google have already conducted successful tests. with the promise of high speed internet especially in areas that have no cover plan would require. it with laser equipment and that. technology could come in.

how exactly is. the data transferred as with any binary computer code a one stands for electrical signal own and is 0 for signal off the data is converted and then dispatched the laser works with the same principle and active laser beam means one while in action means 0 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 that space wedding us here. here the team of testing a rocket that will transport mine aren't laser into outer space. 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. 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 my nerika is still waiting for the breakthrough. with current technology reabsorption is simply too great and there are other options from on the for example cloud cover diversity where you look for a ground station that is excessive and then have the laser sent past the bad weather when. my marriage hopes that within a year telecoms companies will start setting up online networks above the clouds that use of 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 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 can't see. 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 grieve. 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. in the normal frock 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 you can cover up a lot you become

a champion in covering it up of course i've 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 it's meant to be and i have to start looking for it. i don't want my parents always supported me they never said you won't be able to do that if it wasn'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 floor if you can't imagine a blind person can climb a flight of stands you won't believe that the 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.

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 leak. you. 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. going just coming towards us. the app will tell me. to. get lost so it's just it's a good the bus is just arriving now you know my guess is 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 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. but if self driving cars ever become available and i can afford one i might consider moving to the country. 3 set us one cuz you are legally often seen. lights out and off to bed it's not as easy as that for some people account cheap to get to sleep well if you hold off 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.

just con sleep it's like this night after night and you consciously be there. 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. he slept through it. dropped morse can't sleep 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 huge aside 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.

the colby's in germany to learn german colored finical. why not learn with him d w z e learning course because facebook. where the real power resides . i come from there lots of people in fact more than a 1000000000 if you but not just democracy give me that's one reason why i'm

passionate about people and their aspirations and they can sense. the truth and a mission to put this fried chicken bone in after the for the fun in one and i remember thinking at the time if the battle in vulcan for what happens if people come together and unite for a while. but i do the news i often confront difficult situations more conflict being discussed else i see despite my job to confront good speeches on policies and development to put the spotlight on issues that matter most hunger for food security oppression martian isolation. or not has been achieved so much more needs to be john and i think people have to be at the heart of solutions my name is a mcclatchy and i work at g.w. .

but dusty boots muddy tires and drums we deliver urgent lifesaving boxes we give our everything to reach those who need us the most every ball feeding their futures. got synced with our hope of life saving for years in the sun most small down roads with no nines we feel asleep to live a relentless you know promise to make every deliver a special place not just next day but every day. 1000. the children are still waiting for their delivery sponsor talks today so together we can deliver features.
