each a video. link to news from africa the world or link to exceptional stories and discussions from the news of easy. to join us on facebook t.w. for. hello and welcome to tomorrow today this week we're going places really fast. from brussels to barcelona and happen our no problem for the hyperloop a vision of future transit. and talking about future transport we take a spin and a driverless car up by g. test track. also a robust simple and low cost electric vehicle that can be assembled anywhere in the

world. do you sometimes feel overwhelmed by the abundance of new technology like all those relentlessly innovative devices with their hundreds of apps. or wearables computer systems that literally get on your back for the never ending flow of streaming services sometimes you might wish yourself back in a simpler any which. now google engineering is aiming to make that possible. once upon a time this mobile phone with a cutting edge of high tech. 20 years of sweeping the market the nothing a $3310.00 was rereleased in 2017 still has none of today's standard ups its battery runs for almost one month between charges and it only costs $50.00 euros for but many companies aren't willing to risk. relaunching back to basics

models not even a former market leader. because it's often just the fare of devaluing your own brand either because the customers could think it's no longer a top brand or because they're worried that customers might stop buying the expensive model when there's a budget version available. in fact the principle of frugal innovation can be applied to many sectors such as no frills flights or furniture and even some big name hotel chains have been stripping that service back to the basics just a bed and breakfast but a cheap price doesn't necessarily mean frugal. with a cheap product important questions aren't considered like who is my target demographic what do they need to really appreciate the time. instead the focus is on how to make something is inexpensively as possible by saving on materials with a frugal innovation you're looking very closely at who the product is aimed at you

can't cater to everyone. many researchers are convinced the market for back to basics innovations will continue to grow that's good news for people who are happy to make do with less and enjoy a low tech lifestyle. other example. the world simplest electric vehicle. this is the a car an electrically powered vehicle stripped down to the basics designed to be assembled anywhere in the world. its simplicity makes the a car cheaper than regular electric vehicles. sascha that is co director of the german startup behind the project. will leave out all the frills you don't absolutely need like air com heating and any other special features for the interior of a car the bodywork consists of simple for. sheet metal which means it doesn't cost

a great deal to produce. 'd be a car was designed with africa in mind it's a tough multipurpose vehicle that costs less than $10000.00 euros in a matching economies like ghana where the car was tested there's growing demand for products that fill the gap between pricey luxury cars and cheap imports it's common for several people to share a car. many people there can afford to be a go to picture we have of these countries is often not an accurate one things work a bit differently the owners rarely the vehicles user you could call it a form of car sharing would no frills products for new markets researchers have coined the term brutal innovation to describe the development they've seen a growing number of companies decide to design simpler products i think for other things in the works only as these innovations are high in quality but reasonably priced they achieve that by paring things down to the basic features and functions

. rather than trying to offer everything a regular car has they stick to certain clear cut features or to target great needs . that allows them to bridge the gap between low price and high quality. these glasses are also simple in design but high in quality they were also designed for developing countries the basic wire frame can be made locally the materials cost just $1.00 the glasses sell for the equivalent of one to 3 days wages making them fordable for many. but uncomplicated robust products enjoyed growing demand in wealthier countries to something be a car design as soon discovered. we were never even looking at the european market that came as a result of inquiry some gardening companies and organic farmers who said if you have a simple inexpensive electric vehicle why not sell it in europe as well. the startup

hopes to have a car in series production next year for its developers the car is no longer just a research project they founded a company that has 50 employees of who and 30 are students. they hope that sales in europe will make the company profitable the 1st 1000 a cause to be marketed there will cost between 20 and 25000 euros the profits will be used to enable the technology transfer to other countries. traffic with its congestion emissions and noise pollution is a problem all over the world quiet and clean electric vehicles could help. but the wrong materials they use bring new problems extracting these resources often takes place under inhumane conditions and causes ecological damage. so in germany the search is on for alternatives to these controversial commodities.

researchers here at the helmholtz institute in southern germany are working on batteries that can run on apple peel you can use some more matter yells for changing their form and. the aim is to develop a substitute for the lithium used in electric car batteries lithium is stored at the cathode the positive end graphite of the n. o. the negative end when the battery is recharged lithium ion flow to the anode. as it discharges they flow back in the process generating electricity could the lithium be replaced by sodium. is the 1st substitute because it's very close to do more you so we only need to change those light to. get sodium practically everywhere from the seawall there are from sold mines. the sodium batteries are built in these chambers where there's 0 humidity even the

tiniest amount of moisture would damage the batteries. the new devices are wired up to be continuously charged and discharged and they have another surprising advantage. for some of your. what we can use that should be a kind of low cost which is called our government and this can be produced by simply by you always like to have boards for example of what can be defined. by those. by your worst materials he notes shell i would say work in the. apple peel is of particular interest to the scientists because it contains a large amount of carbon which is a good conductor of electricity they just need to remove the water from the peel to prepare it for the battery. here the anode the negative and still contains graphite in

a very pure form that's very expensive. but the researchers think it could easily be replaced by bio waste. they still don't know exactly what happens inside the batteries with these new materials and how the sodium reacts with the other chemicals but they have the technology to perform a kind of autopsy on the dead batteries. we should they say on the side face and the town the electrons coming out from the surface and these electrons are like fingerprints of each chemical that are present on the surface and in that's sense speak and because my eyes what's going on in this set that that's a general and b 10 optimize the chemistry of batteries. the sodium batteries are already working quite well also as button cells they could be ready for mass production in just a few years but they're. less powerful than lithium batteries so electric cars would

need a lot more of them which would take up more space. they have been even the already implemented. so you make a. car would. be . the station i started just for the position of. the institute is also testing another element that would be even better magnesium like sodium it's easier to mind than lithium and it's in abundant supply all over the world. magnesium is a dream solution it could deliver almost twice the electrical charge of its rival lithium. is much higher than the density of your model so if we will be able to develop. there is then it would be

much smaller than the others. and it forms a year which is money so once these. ideas for. the team is testing new materials to prevent that but it's likely to take another 10 to 15 years before magnesium batteries go on the market. in the science by fantasy film black panther the hyperloop is already a reality transports passengers at the speed of sound and it's not only faster but cheaper and more environmentally friendly than conventional transport systems. a university team in the netherlands is working to make fact out of fiction and their hyper motivated. the central train station in cologne germany. a noisy departure point for a quarter of

a 1000000 travelers every day. you know there's almost nothing better than riding on one of germany's high speed rail trains these things can go up to $300.00 clunkers per hour but you know would be even better if the ride were smoother and a whole lot faster. gliding on magnets hyperloop trains could in theory connect all of europe in just minutes that's the vision of the hyperloop team at the delft university of technology in the netherlands. but could researchers in his old university building really lay the foundation for europe's transportation network of the future. remake of north is a civil engineer and she is a very clear vision of what europe's hyperloop network could look like with the hyperloop you don't feel any borders in europe anymore you can just go to a station hop into a hyperloop and be anywhere in europe in no time right now you either have to sit through hour long journeys and train or you're fast with

a plane but you still have to wait extremely long before you can actually board your plane and it just makes travel way more uncomfortable than it should be and then it can be. so is all of this just a pipe dream or will this here one day really be able to transport people at speeds of 1200 kilometers per hour. tim leads the full scale development team and walks us through the idea. so tim what is a hyperloop loop is what we call the 5th mode of transportation the future of transportation it's actually a sort of train that you put inside a tube you release the air in order to create a near fake you so that you don't have much air resistance and it's magnetically levitating so it floats around trick in order to really do diminish the rolling resistance and that way you can create very high speeds and be fairly high energy efficiency so this this thing here floats how does how does it float where does a float over here you see the magnets and right now there are no magnets inside

a jet but there's. a race and a very strong magnet but the good thing about hubble a race is that the magnetic force is going to the. down side so the patients are on the upper hand doesn't notice that it's magnetic so you're going to feel like you're floating exactly. whole back arrays are specific arrangements of a series of magnets to provide a stronger more unified magnetic field. on the track repels the magnets on the train which makes the train appear to float and electric motor propels the train above the truck. the goal of the delft team is to have a european hyperloop network in place by 2050. it's a gargantuan task. up stairs a few dozen young people are dedication themselves to getting

a small pod ready for a race in 29000. everyone involved in this project here are they all taking a year off to do this how does it work most of us are with $39.00 engineers in total of which $32.00 are full time most of us have finished our bachelor's that. the 1st 3 year over education and are now taking a gap year to get a little bit more practical experience so we're here $9.00 to $6.00 every day we're also really looking forward to competing in the. competition and so we really have to work hard to make that happen but everyone in here is so extremely motivated to reach that goal and it's really motivating to for yourself to work together with such a group of people that are all willing to give their time for something like this the team itself has a huge task ahead of them no one knows whether europe is actually going to get a hyperloop network but if we do europeans will be moving a whole lot faster in the future and it will be a lot more why don't. we

asked you on facebook whether you think hyperloop could solve the transportation problems in your country. miguel from colombia writes that despite hyperloop challenges the system of super fast tunnel transit would be a huge development boost in a mountainous country like kids. sorry from indonesia sees a different problem he says if the government is banking on cars even the most highly developed system of public transport won't help. on a valentino thinks that hyperloop will remain a utopia because building it would be much too expensive. but arthur responds that even if it sounds like a futuristic idea at some point our fossil fuels will run out and we'll have to find new clean technologies. and ricardo

reports from mexico that a hyperloop financed by musk isn't planning it would make the trip from guatemala to mexico city in just 40 minutes. right i mean even if they. do you. you have a science question send it to us as a video text or voice mail if we answer it on the show we'll send you a little surprise as a thank you come on just ask. your buy this on line and on twitter and facebook this which your question comes from okello mickie oh man you well in uganda. how do autonomous cars avoid accidents. an autonomous vehicle constantly monitors traffic with cameras and a variety of senses it's claimed they can recognize potential hazards and respond

to them even better than a human driver can. a stereo camera detects road markings and other road users. radar senses and the road as far as 200 meters ahead of the car. is a scanned everything in 180 degree field of view. and ultrasonic senses measure the distance to houses and other cars using sound waves that bounce back off those objects. and they also draw on the latest digital map updates from the car sat nav system. so it's bullet proof right. well in fog a camera can only see as well as a human can heavy rain and snow fall also interfere with laser and radar beams.

most of the fully autonomous vehicles have been on the road only in sunny california and even then they've had a few accidents along the way. one woman who suddenly appeared out of the dark much like this was even killed by an autonomous car similar accidents happen with regular vehicles as well. self driving cars would use artificial intelligence to learn to respond to sudden hazards the way a human would and that will take time and. there's little doubt that autonomous vehicles will eventually make traffic safe and about 90 percent of accidents are caused by human error and those won't happen in fully autonomous vehicles. they can't fall asleep at the wheel don't drive under the influence of alcohol and won't become aggressive either. many people complain that autonomous cars

will make driving boring but in all likelihood passengers will find other ways to stay entertained. 5 g. promises super fast internet and stable connections that will enable more and more devices to communicate wirelessly with one another. the car industry has also discovered the potential of the mobile internet. from test track near austin its home to germany 1st working 5 g. transmitted mast technology that claim to make mobile connectivity as fast as fiber optic cables that work for smartphones with 4 g. and not exactly slow coaches either. from. 5 g. is necessary to enable real time communication and danger transfer such as an industry

where robots have to work together in synchronized teams or in road traffic or cars exchange information in real time to warn each other of hazards. network providers have discovered the business potential in cars. they want to make instant vehicle to vehicle communication the new benchmark. current mobile connectivity is too slow and too unreliable. in future everyone will be communicating with everyone else and traffic cars will become 4 wheeled smartphones fitted with a sim card similar to smartphones now but traffic lights. cyclists and others will also be sharing information with each other. researchers at the technical university of arc and have built a test car. here in their outdoor lab they're probing the possibilities of autonomous driving with 5 g. . here fortune woman we're looking at 2 core aspects right now

for one the safety the most important aspect for us you know we can use 5 g. mobile performance to make car safer because we're accessing an additional data source and then there's the improved comfort of autonomous cars which allow the driver to do something else besides driving. the car will be equipped with a kind of radio based protective shield system will receive constant updates on weather and traffic conditions and information from other vehicles. if a car ahead spots a hazard the information will be shared with vehicles behind it which can automatically brake in time to avoid accidents. you know every driver knows what it's like to be behind a truck and not be able to see whether you can overtake it. in the

future mobile communication will allow us to look through the truck would be able to see if there's a car coming the other way whether it's safe to pass it. until recently mobile telecommunications and car manufacturing had relatively little in common but now automation experts are thrilled by the prospect. marrying the 2. 5 g. is not only faster with barely any time lag it's also more robust and that makes it more suitable for use in safety features. view for mobile technology allows us to effectively see around corners that's such a huge advantage that in future it will definitely make sense to transmit a signal that makes you visible. cell 5 g. networks could potentially alert us to hidden hazards as well. as something like a pedestrian around a corner smartphone signal can be detected. this is.

the signal that someone is about to cross the road could be transmitted via 5 g. . the vehicle could be automatically brought to a halt to avoid hitting the pedestrian. that's the syrian least but will it work in reality the test answers the question. 'd what's interesting is that there isn't spotted by the driver the human. any sense of a systems like cameras or radar. the pedestrian isn't visible out of sight around the corner. but infrastructure analytics and 5 g. communication can transmit that missing data to the vehicle. so on line highways with 5 g.

coverage promised to be safe and when accidents do happen the response of emergency services will also be optimized. design the future approaching ambulances will automatically warn vehicles ahead of them which will also be told how to form an emergency lane quickly and efficiently. in other words the autopilot steps in whether you like it or not your vehicle will pull over to one side on its own. denise's should have been vocal here in the next step will be to leave the testing ground and head out into the city with real traffic and real people. to begin with testing will be restricted to small 5 g.'s omes such as limited stretches of highway for now blanket 5 g. coverage is still well beyond the horizon.

that's all for this week's show next time on tamara today how data could be stored for a 1000 years on t.v. and they not only is a tiny it's also extremely durable try less then to find out more see you soon but i.
