miss things or christine brain damage. so let's stop this self sabotage humans and multitasking. watching our new to v w documentary, the wireless charging has become a common feature in many cellphones or electric calls. next, it's technically possible to transmit pilot not just to cause, but also buses and trucks, even while they're in motion. on this day we'll take a look at how it all works and check out the current state of inductive charging in vehicles that are on the road. is it the future of transport? that story and much more this week on the dw sign saying, welcome to tomorrow or today, the no link to the test car, the charges up while i'm moving down the road. as it rolls along the test track,

the batteries are top top guidelines should be able to work even if it's snowing or raining even without any direct contact between the car battery and the road energy can be transferred from one to the other on a smooth university the really innovative thing is that the charging is roughly as efficient as with wired systems. sparkman cobblers give the notes or statement. the team says 92 percent of the energy from the charging system in the road actually reaches the vehicle. an unprecedented efficiency rate is really company. electron has demonstrated that the technology works in principle. and the 1st modules are already being installed in some short stretches of road together with the university of ad long and in germany. the firm wants to build a one kilometer long test track on a freeway in that area by 2025. so how does charging vile driving actually work in technical arms?

once that is possible, wheels installed in the road, carrying the alternating current which creates an alternating magnetic field. and that fields generated by the magnetic coils in the road, transfers energy to a 2nd magnetic coil, and the car generated current to a wireless process known as induction. the system in the road also knows the cars location. that means data can be transfer. so later, the system can determine who has tanked electricity and how much important information for billing experts say an e car is range could be increased by 20 percent. if long enough stretches of highway are retrofitted with this technology in the future. but highways aren't the only place street induction has been considered. where might it appear 1st? as i'm into it alternately be more successful in city traffic where smaller

electric vehicles are more likely to be usable or on highways for longer distances . it's the market that will decide side. the idea is not entirely new. an induction, a bus called tamia that's been on the road in the german city of orange 5 since 2014. the charges at a bus stop. not while driving a few parking spaces of also been equipped with inductive chargers for charging one on the road has mainly been tried and bosses. one energy provider is testing a 100 meter long section of induction capable road and cause that has an efficiency of up to 85 percent. the technology will soon also be tested and autonomous cars that could help eliminate unnecessary downtime for charging and increase range. but if enough roads are converted to normal drivers could also benefit because batteries and commercially available cars could be less bulky than they are now. might the technology perhaps even save like tricity in the future?

the spot is like the blank costs will be lighter, so will consume less energy, but still have the same speed and characteristics of full. so we'll save electricity spot. but since building the new infrastructure will also require energy, it's not yet clear whether or how much electricity the technology might say. but one thing is sort. since inductive charging would lead to smaller batteries, it would reduce the need for lithium and rear arts. but do magnetic coils has to be installed in the streets to the same thing be accomplished with overhead lines tests involving them and electric trucks are under way. wouldn't they be cheaper to my mind? you might think so. but over headlines are always problematic because like when there's freezing rain, for example, or even just during different climatic conditions, then energy transfer is less efficient and you get back to talking to me. so if it's in the road based magnetic coil technology, by contrast,

works and bad weather, ice and snow. and even though inductive charge, it could also benefit cars. they can't reach overhead lines, only trucks and buses can. incidentally, the magnetic fields on converted roads aren't dangerous for drivers or pedestrians but at around $1000.00 euros per meter building cost. the technology today remains far too expensive for large scale expansion. but that could change by now there's a funny example that fits the conduction stove. so the 1st prototypes were extremely expensive. now they're cheap. i think we could push the price down to $300.00 euro. so for the indian store, if the technology grows cheaper, induction capable of highways in the future for the only slightly more expensive than conventional ones are now, hopefully that's in. so i hope that it will be feasible in 10 years or less. as soon as we agree on standardization and regulation goals, i mean after that things can move quickly. what's still missing or uniforms

standards that all manufacturers have to stick to. that would ensure that the infrastructure could be used by every one. but 1st, the technology is advantages, has to be demonstrated convincing way. let us read why on the view of a special science question, send it to us as a video, text or voice mail. if we on switch on the show, we'll send you a little present as a thank you. come on, just ask. this week's view question comes from the via e b as in pop way the what causes the mild electronic shock that sometimes occurs when you touch something metal, everything around you and your body as well is made up of tiny adams. these in turn contain electrically charged particles. they are the positively charged protons in

the atoms nucleus. and zipping around that nucleus are the negatively charged electronics. so your body is charged and electrical charge normally flows back and forth between you and the environment. without you noticing a thing the moisture in your skin and then the air helps ensure that charge doesn't build up. if it turns cold and dry though, charge exchange no longer works as well. when you then walk, for example, on a synthetic carpet and shoes with rubber soles, your body grows more electrically charged with every stuff. friction causes electrons from the carpet to transferred to your body and accumulate there. because rubber is an insulator, the electronics can't flow back into the carpet. the same thing happens in this experiment. inside this metal spear, a rotating rubber band, leases electronics,

charging disappear electrically and causing the plastic strands to rise in the air . the same happens to the hair on your body when your negatively charged. and when and electrically charged object comes close to a conductive material or a body with an opposing charge. it discharges southern light up to 35000 volts can flow through your body and causing an unpleasant but harmless electric shock. keeping the air from getting too dry in your home or office. regularly applying moisturizer to your skin, wearing shoes with leather souls and choosing clothing made of natural fibers like cotton. those are all steps that can help prevent shocks. electricity can be tough to do all kinds of things. like coming this up a month and to go skiing and some of the energy that drives cable railways can be recaptured from the brakes and used for other purposes. one hotel in switzerland

has honda state for heating. the stores bond in switzerland does the steepest the nick killer train route in the world. places the cable railway car climb is a gradient of 110 percent rising up from the municipality of fluids to the winter ski resort of stores at 1300 meters. because of the steep terrain, the train often has to break hard. this generates energy that can be recovered enough energy, in fact, a heat, an entire hotel bill next to the trucks. in technical terms, the process of capturing this power is called regenerative braking. engineers and a call explains the principal, linda trains engine room. the thing you can see on the entire drive train at 1st when starting off, the train needs energy to pull itself up. the steep slope through the car is then passed each other in the middle. that's where the tipping point is from then on. i

the, this means that the electric motor 1st requires power and then starts producing it halfway up. we use this electricity to heat up. the water to me at the effect is a surprisingly big 1. 410000 kilowatt hours of energy is generated by breaking and waste heat yearly. to get the equivalent, you'd have to burn 41000 leaders of heating oil. it's energy the hotel can tap the generated electricity, heat water, just like a plugin, tea kettle. there are large water tanks in the basement to store the the fact that the hotel is located right next to the station is ideal for the back. but your interest rate is going says mean less heat law of i would say in terms of construction, that's the thing. so close meant far fewer interventions to set up the connection. yes, the hot water flows to all of the hotels, $100.00 rooms and it's kitchen. managing director, mazda neu,

house is happy to tap the energy from the mountain railroad for heating, especially in an era of high energy prices. made on the, on the deal with the stores bond, you can purchase electricity at a discount on the how? no, no, because kind of the money we pay, it goes straight back to the train. i'll look at actually that all the so it stays with us here locally with me and we have a small circular economy going. it's a perfect fit for us to handle the philly spots develop through many hotels and restaurants in switzerland are located near similar stations and they have big energy needs. so there's huge potential for other projects. according to engineer olivia do veneta from new simmons university of applied sciences, the sustainable idea can easily be modified for other locations of the yeah, the know his music on the application itself is not very complicated, but the cable car technology and the building technology, you have to fit well together, if they do,

you can get great projects off the ground and you come on the political you the or foot license back to the mountain for the 1st guests are being welcome to the newly built stewart lodge. it's cozy and warm. a task that come and you can take a longer hot shower here with a clear conscience least probably like warm showers, heated by the brakes of a nickel or train as it slows down on the world. steepest set of tracks energy from the brakes on a mountain train could theoretically be used to do things like pallet also visual smoke on in the growing less common in switzerland. because another firm has come up with climate fund. these no licenses which make all the technicians know without using any electricity at all. at the may say food ski area, snow production is in full swing. the resort use is what are called snow lances for

the task. they work entirely without electricity. the head of the company, the manufacturers, them close down to shows off the revolutionary technologies latest design process. yes, i, it's nice to, this is our most recent model which has a 3 head dies. it's all about making as much snow as possible in the shortest possible time, said warmer temperatures, deceitful. he's proud of the most powerful machine in his line up with the 1000000 was added. so from when new models work like they do here and the water really turns to snow, that's great. this snow banking firm operates the kind of open air laboratory and the sky area and works together closely with the team. it makes the foods and has been testing snowed, lances here for years. they play a key role in creating good piece. in fact, without the lances as the head, snow maker confirms the resort would be hard pressed to survive. only takes

musician in without artificial snow. we wouldn't be able to keep the ski area in operation. we can't rely on nature alone. the since actors played roles in the decision to use energy efficient snow, lances may say to those loans. we rely on them as easy, they're cheaper to operate and to maintain and they're less on site lee and us landscape than a tower with a snow count. and on top of it as a rule to produce know, most conventional snow cannons and snow lances need compressed air and generating that and requires energy. but the lance is, can obtain this energy from naturally occurring water pressure. canons can it's been a long road for the company. the 1st reports of a swiss made 0 energy snow, lance 1010 years ago, a metal monster called nessie 0. he tested where else that may safe, quote,

close done. it was there to use the theme explained that the device makes no without energy. that's a counter intuitive idea and holly and that's because they get all the energy they need to do it from the water spring at high velocity out of the nozzle. so from that comes from a lake higher up in the mountain to see with and the difference in altitude between here and there. she provides plenty of water pressure and they'll see that will cost us without function 8. yes. that 1st field test 10 years ago was a milestone. but even if not, everything went smoothly. it's very, very simple. and this is you know, i mean we have some minor problems with clogged to nozzle due to dirt and water that wasn't filtered. there are always little unforeseen things, but now it's working is it should and dine delighted eyes to these over,

excuse me. yes, we do up there. you can see how the nozzle on the left vaporizes the water that's on the beach. so those water droplets have been blown into the path of a jet of ice particles and they mix together and the water droplets freeze creating tiny balls device. and that's how artificial snow is made on the consciousness. messy 0, he worked, laying the groundwork for future generations. that the device you all detail every august since then we've continued to develop the snow lances that work without energy input. it's we can now produce 3 times as much snow in state and even in the border line temperature range. they can still produce a lot of snow in a couple of the snow advances are made in the town of him and book over a 1000 units lead the automated production facility every year. the company's sales doubled in 2022 is in san suite and we're very satisfied. it was

a very good year, but we always incorporate technical innovation that helps our company move forward . language solve the threat of energy shortages has given the business with efficient snow lands as a boost. more and more ski resorts are switching from conventional snow canon's. so what does the future hold tail aid to shipments that are in syria at least we've achieved the goal of 0 energy and snow production. but there are always new challenges. so it's like a shorter a cold periods and longer warm periods thing was involved in november or december. and you sometimes have to have all the slopes covered in just 3 to 4 days. that's why we rely on multi headed lances for a lot of coverage and a short time. this is just one small section of a gigantic suspended snow making machine. the technology could potentially be used for more than to just save ski slopes, a plan and visions, it stretched over the,

disappearing more to arch glacier to cover the ice with a protective layer of snow and possibly delay its melting by decades. the company is supplying the key components for the project, but isn't the idea of little over the top? it's all that we believe in the project and are sure it's going to happen. the glaciers are melting and once they're gone they won't be able to get them boxed the, let's use our receding and the out of a new non mean pace to, to climate change. the mountain range is moving infested in other places and that has knock on effect. so many animals, including my great tree bids, some no find it more difficult to cross the outs as they head to woman times in winter. among them, a species that disappeared from your skies, centuries ago,

which experts and now trying to re introduce the node in bold ibis. on your mark gets that ads there off. a flock of northern bald ibis is learning the best route to southern climes position to 6. it's in the 16th time . i've taken a trip like this, but never one over such a long distance. one. it's a very special moment. the concept is on the moment. it's 7 in the morning at pending an air field on lake constance. you'll honda splits and his colleagues are making final preparations. they've been working towards this day for months. the team wants to guide young birds on a new migratory route. is blaine but invited to the problem is that when left to migrate on their own, just a northern bald imus is now leave later in the falls because temperatures remain warmer for longer was in day last year. they only set off at the end of october

after teams, but their normal route is over the hours. and later in the year, they struggle to fly over the mountains because they don't have the thermal super fleeting binding down them exceed the northern involved either this could once be found all over europe. then hunters drive the species to the edge of extinction. this project has helped establish several wild colonies of the birds in germany and austria. they usually spend a winter in tuscany. however, as the climate change is so does their migratory behavior. because the elves are becoming such a barrier. this year the flock will head for and to lose. yeah, in southern spain. the young bird should be able to manage that even later in the year of the birds were born at the end of april lead cause was due. the northern bald ibis cheques soon get used to their foster mother's helena and father of flight training at lake constance begins in mid. may. the birds quickly learn to

follow their to humans, even when they climb into ultra lights and take to the air. again, i didn't want to hear them. this boy generally encourage them all the time, so we call out to them and try to cheer them on a bag so that they stay motivated during the flight. i haven't got them through from the wheels. the young, northern bald ibis is manage the long journey to spain. the 1st stage is a risky one. the birds are flying lower than flocks and previous years, and this far down danger clark's many high voltage power lines crossed the flight path. this is the kid's is not so great to fly, so low as a pilot and we really have to take care of. but we also worry about the birds a lot because some of them fly under the lines. others through them or over them then. but i will tell you that, but after a 70 kilometer flight,

all 35 birds in the flock, land safe and sound at the 1st planned side there they get a tasty treat for making it this far. neil armstrong, helena and bob, i then wait with their charges until the other team members arrived to set up the aviary. the temporary lodgings for the young, northern bald ibis is, are transported by grounds and has to be assembled and then dismantled. after every stage. it takes a while for the birds to move into it, but the foster mothers are patient and the end of a vague stuff at the moment. we're just happy to have completed the 1st stage. so if everything takes half an hour longer, that's no big deal. you can't stress out too much, you have to give the birds time. that's the most important thing. otherwise they won't come down at all. and after a one day break, the journey continues the flight down to lose you as almost 2300 kilometers, nearly 3 times the distance to task and it will the birds make it and will they be

able to find their way back the thing. and if you will get the birds down there, hopefully, and then release them into the wild and see what they do have now they survive. which habitats that you need to find and whether they decide to fly back to germany again or line next to ball loose give you the how fleeting. if the birds do there are plans to settle them here and few by like on lake constance. it takes 3 years for northern bald ibis is to reach sexual maturity and make their way back to where they came from. as they've been in that i. and when the 1st birds come back from spain in 3 years time, unless they meet another northern vaulted bits along the way, it's very likely they'll return to the near field where they were trained and where they grew up and. and then we can catch the oven, how down to the colony here reset the animals and human space constant challenges on their long journey. at times, strong winds disrupt the flight plan and attacks by birds of prey or regular danger

. members of the flock also disappear occasionally, most are found again, but 3 of the birds stayed missing. despite those hurdles, 6 weeks and 19 long stages later, the team reaches the south of spain. yet kind of a reason for joy back in germany as an opportunity to catch up on the progress of the project. i'm a former foster mother asks the new ones how they're settling in a report that their spanish counterparts have been very warm and welcoming and signed up. the northern bald ibis is our slowly growing use to their new environment and, and to lose yet the spanish partner project on site for a later integrate them into a permanent colony in the area. the zip codes as much to look with a barbara and helena say they're returning to germany. i feel like they're leaving their birds in good hands. they'll return in december for the release into the

wilds and tell them to sun out. for now, they can enjoy the satisfaction of a job well done, and hope that one day their boards will day or the long journey back to germany. do you have a passion for science and health? check out d. w signs the contract talking. why do coming? does not get drunk. why do gravitational waves squeeze out bodies? how much was it? do we need to pay days? do stressed out on screen for help know? and what is the perfect queue of football by find beyond says yes, mos on dw science. oh, tick, tock, channel. that wraps things up. so this time around for tomorrow today, the science. so on dw, thanks for joining us and see you again next week,
