100000000000 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 oh let there be light its 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 earths surface and now with a related old night long there are still many places that dont have electricity and cant afford it that doesnt have to mean being left in the duck these next women have traveled from all over the world to india to learn how to build Solar Systems in half a year theyll return to their villages bearing the gift of light. God wanted me to go to india. Right here i remember the day i said to you. Im doing this for my children. These 3 women had never traveled far from home before and now theyre in india theyve come to train a solar technicians. That come from mexico. Kenya. And indonesia. The program last 6 months and every school day begins with exercise that many of them dont do was sent by her village in kenya where they dont have any electricity. There eagerly awaiting her return. We all know that darkness is not the best thing 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 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 its all routine. You mean it comes from west timor in indonesia. Without light my children cant do their homework and when it gets dark they have to go to sleep when i get home were going to have solar lamps. 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 whereas solar electricity is reliable the sun god shines for everybody and doesnt care if youre rich or poor. If you cant 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. Both and what how would you who are you know why you know what you know of. 3 and a half 1000 socalled solar sisters have sold almost a quarter of a 1000000 solar. Cells from light to almost one and a half 1000000 people. On the course is isabel more humane as well head back home to mexico then she have to work out how to use the new skills and knowledge she quiet in india. When i see me react when i have no idea what ill be able to add now but what matters once that is that ive learnt so much. That the people at home will see that i can do good work. Its been quite a sacrifice to come here to learn something new and then i want my book. To cases financed by the Indian Government and the United Nations and a number of businesses one student graduates and head for home to have plenty to tell their communities about their adventures in india. In. Well light doesnt 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 to now focusing on new applications in agriculture like bringing high tech farms into the hearts of cities. The earth is home to 7750000000 people the majority live in cities green spaces are shrinking. How viable an option is. For example green houses led by l e d lamps even in buildings without sunlight. Any d. Light bulbs provide illumination by day and night and the plants compete harvested at any time of the year. Becoming standard Lighting Solutions in greenhouses they have long been undergoing testing here in the netherlands in the look barratry of the signify its europes biggest lighting manufacturer and a spinoff of Dutch Technology giant philips so far the company has equipped around 1000. 00 greenhouses with Lighting Systems we have 4. 00 inside so its red its blue its white then its far out at a far it is typically pretty are known to us because its outside of our i sensed a particular. 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 so thats the sweetness of the strawberry but also make it a little bit more hardy or lets say show that its 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 had less sunlight than those in. Spain. 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 its not because they dont make money that Companies Like are growing fast in russia with by 25 factors and 25 factors its 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 is in paters its greenhouses measure 16 hector has an area amounting to Something Like 20 soccer pitches. The crops are aluminum to buy magenta any delight from below and from above by high intensity High Pressure sodium or h. P. s 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. Must be about 80 centimeters to one metre. Below the top of the plant because the top of the plant affected by the lightning and the light. And one metre below the effect of the daylight. 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. This is very sweet. But whats important is that the taste. Stays in your mouth for a longer time so this not only the place is gone immediately. With a certain bite 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 a major disadvantage of this kind of farming the energy cost of producing artificial sunlight outdoor farmers get 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 didnt 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. Germanys. 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 like vaults have been phased out and the e. U. The Leading Light of the 21st century. 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. 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. Or automated intelligently for efficient lighting and factories or businesses. But the problem is that if everyone thinks theyre saving money with a fission lighting theyll 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 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 anywhere 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 startup that has developed ground stations for wireless Data Transmission via laser beam. Internet super highway 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 gram station operated by the company from that its relayed file to the next link in the airplanes High Altitude balloon and. 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. Dispatch a great deal of communication. Which is why 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 and special. Coverage. And that. Technology could come and. How exactly is. The data transferred as with any binary computer code a one stands for electrical signal own and their own 1st signal. Converted and then dispatched works with the same principle an active laser beam means one while in action. The connectivity provided here is 10 gigabits per 2nd in 4 seconds thats an entire feature film. The makers expect the technology to work in outer space too with satellites distributing the laser light that currently testing components for that space webbing us here was. Testing a rocket that will transport mine arent laser into outer space. Your 1st. Of course we try to qualify commercial components for 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 can still waiting for the big 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. 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 they 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 cant see. The spy that theyve managed to overcome employer prejudices themselves out successful careers. Let me know when it starts to hurt. Can you still speak. And breathe. And 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. On the far. Right most of my patients dont even know. When i tell them im legally blind they say they dont believe me. Or that was a quick. One can verify 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 things in the wrong place. I get so mad if i have to spend hours hunting for something if i reach for it and its not where its meant to be and i have to start looking for it. One of my parents always supported me they never said you wont be able to do that. If it werent for my eye problems id never of met my husband ive 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 lane is very noisy very crowded and people just leech other a lot its 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 here i locate the steps with my stick i know the courthouse building very well with all its corridors and corners. And sighted people often get lost here and cant 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 cant see i dont judge people by their exterior because i cant that also means i dont get distracted and remain focused on what people tell me. But that doesnt mean im entirely free of preconceptions theyre just a bit different blind people might not like the sound of someones voice or the way they shake your hand. Im not a living light detector but i am pretty sensitive to what people are telling me whether its true or whether theyre lying. For money for if you cant imagine a blind person can climb a flight of stands you wont believe that a visually impaired person can hold their own in the workplace. Ive been blind since birth but when i say im on my way to work people ask if im 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. You. 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. Thats called leak. Guy do you. Write 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 so. You dont have the app will tell me. What. Its up to its just that secure the bus is just arriving now you know what thats done but that cant be recognised by the app so it says the next one is delayed coming in 10 minutes it doesnt show the one thats just come in so. Its been its no melindas style of in town because theres 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. We often think of. Lights out and off to bed its not as easy as that for some people they count sheep to get to sleep well if you hold off think you hit the town and hes clearly not alone in it sometimes it feels like the whole city has insomnia so whats his advice make the most of your nights. Just con sleep its like this night after night and you consciously be there. The whole city is awake so many restless. During the streets lost in thought. Well since we awake anyway we might as well hit the town into the night life into the light. Sleep listened to lamb can be dots of fun the lights the collars the atmosphere late at night its inspiring better than counting sheep. For some fantastic sights i had a fabulous night just think i knew. And he slept through it. Laugh most consciously burn your bat just go with that. Plan it grows around 2 percent brighter every year doesnt 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 youve just side whether thats a good or bad thing time to turn out the lights in the studio hey thanks for joining us im 8 he said. Small acts can inspire a big change in the people making a. Go africa fantastic. Join them they set out to save the environment learn from one another and Work Together for a Better Future for.
