from politics to flash from housing to feel good top this is where they are. welcome to the 77 percent. this weekend d.w. . there's a tendency to think that a bigger is better consider diamonds houses cars but it's often the little things that really makes a difference some so small you can't even see them from nanotechnology to micro homes and amateur traders they're all making a splash and demonstrating that size is actually relative when small is big that's

our topic today welcome to made want to get jones in berlin it's good to have you with us now back in grammar school i had a teacher who wasn't actually told he was a powerhouse he used to say i'm not small i'm concentrated his lessons were very intense and successful even i had excellent grades in mass and physics small and concentrated could also apply to nano particles they are found in lots of modern everyday products to make things water repellent for example but what do we actually know about those super tiny nano particles and their interplay with our lives mitty audition it reports. this is a song to lotion with not all the goods. 1000 nanotechnology have to do with me. which drug issue polish containing nano

particles were supposed to make the polish absorb into the shoe better it didn't help the much. but it seems there is something new for me after all in the wonderful world of miniscule artificial particles. i have a broken man all of which has to be replaced with a dental implant until now there was a risk for bacteria would attack the implant and it would have to come out again but the none of coaching of silver can protect against bacteria in the future. critical schneider from german company arias has developed a coating for dental implants. technical development takes a few years if it happens at all. and then there's the certification process to prove the whole thing is safe. that it often takes years at least a decade. because the hurdles are high. they want to avoid putting the

consumer at risk in any way and that's a big challenge for a small company like ours the stringent demands are also slowing innovation. you can see 1st and whenever i contact the medical equipment makers 9 out of 10 of them say they don't want to pursue it because the regulations have become stricter or they have become too vague leaving no plumbing certain. actually it. can also be found in many foods such as chewing gum and baking powder where they make the whites appear even brighter it's basically just a coloring effect. critics are worried about the use of tiny particles in food though. we know that certain nanomaterials cause inflammatory reactions in the gastrointestinal tract that's a precursor to cancer and the kind of thing we must prevent is you know so why is it that something like that gets

a license when it can cause inflammatory reactions. the reasoning was there is a labeling requirement for nanomaterials in food but you won't see any foods labeled contains nano products that's because we're still arguing with the various industry associations about whether it still has to be declared as such because they say they haven't used it as a nanomaterial but there are all was some nano components in the product itself. ok honestly. truly through dangerous. nanotechnology is one chance of territory rich in potential. i would like it. but then not everything that's useful is also edible so that shouldn't be a criterion when deciding whether new technology is worthwhile and when it comes to nanotechnology there's still so much to explore in recent decades scientists and

engineers have learned to make and manipulate nano particles and nano structures and deploy them in products and processes the range of applications is enormous and expanding fast see for yourself. small smaller smallest nanotechnology. a human head has a diameter of 50000 nanometers one nanometer is just 150000 of the diameter of a hair. here's another way to visualize it one nanometer is 2 a meter what a hazelnut is to earth. nanostructures how fascinated scientists for decades now they're even able to make some of those structures themselves they can manipulate matter at the atomic and molecular level so that the matter takes on new properties. industry has discovered the virtues of

various nano particles many sunscreens now contain ones that block u.v. radiation. silicon nano particles are used in smart coatings that make fabrics water repellent that's a novel way to waterproof clothes and upholstery. super sticky glue tennis balls that keep their bounce and unbelievably tiny computer chips all thanks to nanotechnology. it's become big business sales of nanotechnology have been growing at an ever faster rate. one estimate put the global market value in 2020 at 63000000000 euros. the nano technology is said to revolutionize many sectors in the field of medicine research is intense and wide ranging. it's also contributing to environmental and climate protection. nano scientists even working on self healing materials imagine

a crack in an airplane wing that repairs itself with nano particles going where they're needed for now that still pie in the sky but perhaps for not much long. nanotechnology is really taking off. now severe lack of space has led to a shortage of fordable housing in many big cities try finding a flat in berlin a nightmare as a result some people are setting their sights on something smaller a tiny house and conventional lodgings are already popular with holiday makers and $28.00 in abyan these are roughly 125 percent increase in worldwide bookings over the previous year the figure for barnes was 110 percent and shepherd's hut came in at 93 percent plenty of people are also looking to downsize permanently so we met a successful tiny house builder in germany and an architect in hong kong says small homes are key to overcoming homelessness.

i think of the product design and has built herself the house of the tree. if you live in a tiny house i live in a tiny house. i used to build which is quite different. when i left the film industry and travels for a while everything i needed was in my backpack i went to a tiny house is a lot like not everything you need fits into one room and there are lots of places to store stuff away from everything else multi-functional. she works for stephanie. he started building tiny houses 5 years ago and now has one of the biggest manufacturers in germany. he builds foresee a year none of them larger than $25.00 square meet his. first saw them in canada. i spent some time there and saw how they were

building micro houses though they weren't mobile homes on wheels the idea really fascinated me. from. then the trend reached europe from north america we picked up on it relatively quickly and decided to build a prototype and see how it goes down off more important to almost. this starting price is 45000 euros for a house like this some customers want to live in their full time others just for holidays either way you can't cram much stuff in here. many minutes many people have come to appreciate minimalism downsizing arleen living we know that because we see lots of people here who think that way. if the 1st time that if you're living in a small space is just one aspect of minimalism more generally it's about reducing your c o 2 footprint oh i don't know i am parted from 2 my minimalist most so choosing to live

in 20 square metres rather than 60 square metres could be part of that or to credit me to von behind so no further north tons of metal in hong kong for example 20 square meet his is quite stand it and still very expensive lots of people very close quarters they can't afford more space james lowe is an architect based in hong kong he's designed micro homes in segments of concrete water pipes he calls them oh parts so i came up with the idea when on one day i was on my construction site and i saw some of these fairy large concrete water pipes being laid into the ground and i walked into one of them and they were big enough for me to go inside and suddenly i felt that this source instant architecture this is like an instant shelter which with a bit of design and

a bit of creativity could be quickly made into a small house. he says these low cost units can help eradicate homelessness and ease the shortage of affordable housing $120.00 units are said to be built in hong kong this year more are to go up in canada. lost says the world needs to rethink housing as the population source. homes will have to get smaller. the cities asked so. so expensive to live in space is so tough to get and so many people are chasing after that space so that in a way the architecture we build is no longer so affordable for people so maybe this idea will become necessary in some form in every urbanized area you know well because we realize that we cannot always just build iconic and expensive projects

for a symbol of our city we also need to really take care of people otherwise the people will really excel. hung congdon is only one of many cities where housing is very expensive and in short supply. stephan dyckman says the market for tiny houses is going to be here to. tell because i for i think people have become more flexible nowadays they're not so bound just staying in one place with a lot of computing. well that's another reason for choosing the trainee house for i'm about this for the entire year i was dyckman plans to open a tiny house hotel once the pandemic is over that is the pint sized units are ready to go each one is different. i think our focus doesn't need to be convinced she's already a fan and says her tiny house gives her everything she needs. it should be easy to keep clean moving on to the world of stock markets more and more amateur

investors are trying their luck these days and they're even sending some stock prices soaring but in this very risky business the stakes can be high is my colleague chelsea delay me with the lowdown on day trading. the beating heart of germany's financial industry the frankfurt stock exchange but it's a little work down between stable trading has moved from stock exchange floors like these to our phones and laptops deals are done while waiting for a friend or for a coffee and by people like you and me even my mom's doing it amateur investors have flocked to stock markets like never before since the crown of iris endemic began well it has devastated many people's lives and jobs other people have found themselves with extra time and money during walk downs and this record breaking rally we've seen in global markets has made many people already very rich. the s. and p. 500 in the u.s. was up 16 percent and 2020 but that's nothing compared to this day trader favor at

tesla more than 700 percent i've been covering stocks as a journalist for years but i'm ready to get off the sidelines and try my hand at being a pandemic do you trader. the one to 2 platform when a lot of people think about trading stocks their mind conjures up a scene like this thank you. and while you still can trade stocks by calling up a broker trading has increasingly gone digital setting up an account as easy as downloading and now there are dozens of free or low fi options out there to choose from step 2 choose your stock. car day traders make hundreds of transactions every day others like me have day jobs and only so much time for writing market swings so i have to make my investments count. oliver wrote as

a trader here in frankfurt he says we should all be trading stocks because ultra low interest rates mean more traditional investments like savings accounts no longer pay. there's no really a turn or 2 of to stock investment when you look at the interest rates they are so low it's not possible to save money on the account or somewhere else so this is just without in the term that if therefore even the private people the private investor retail investor is very interested in stocks even in germany which is not very popular on the on the stock side today is the 1st day of my experiment as a pandemic the trader what and by step for me as a newbie from a professional like you. were 1st of all if you go to the stock exchange you have to be very disciplined that's very important because you need to think about where you want to invest why you want to invest and then you have to be disciplined by saying this is where i am going the price is where i get in and where i

will get out should i buy a tesla you shouldn't invest only intensely you can invest in tesla because i think there's a lot of things are going on but nevertheless you have to to to to spread to a risk to divide your risk on certain certain pillars and tesla could be one of them but also other stocks have to be in your portfolio which is very important ok so oliver says i shouldn't. all my eggs in one basket i'll be buying a mix of company stocks and exchange traded funds or e.t.f. which are seen as a bit safer because they include a variety of stocks since i'm a journalist who cover stocks out the investing in the stimulation mode of my app which is a good way to try out a trading without putting your money on the line for the aspiring investors out there step 3 know your timing ok so let's see how. i started out with 100 euros on day one i bought telecom amazon and an e.t.f.

that tracks european banks the markets went against me and i ended in the red. 'd states you want a little better thanks mostly to task which continued its relentless rally. 'd after 2 days i ended down a little more than 2 euro zone's. but it could have been worse trading is very risky even the most experienced wise and investors often find themselves caught out by market swings some studies have shown that around 80 percent of day traders end up losing money and some of these new platforms have been accused of manipulating investors and under playing the risks of trading. knowing how to time markets when to buy when to sell is one of the hardest parts of investing many traders are eyeing this rally warily chilled by central banks stimulus markets climb higher and higher. really deeply concerned about the situation where were you home as long as

the central bearings are making the money so cheap. the longer the bubble can grow so i don't see i see a photo but i will see that the bubble explodes i see that the bubble rickrolling grow and grow for certain time. as thoroughly i didn't strike it rich as a day trader but it was just a simulation after all and i'll be keeping my day job. good idea for making a windfall on the market too profiting from wind itself germany won 65 percent of its energy share to come from renewables by 2030 and that's a tall order given that over the last 10 years the shares of wind power in germany's energy production only rose 19 percent from 6 to about $25.00 it will take many more super sized wind turbines to hit the bigger target but if you put them we visit a winter under construction in northern germany. new

wind farms a cropping up across germany these technological marvels a taller than the world's highest church tower bigger is better and more powerful. germany's long term goal to become carbon neutral relies on harnessing the power of wind. down at the construction site workers are assembling tower segments the towers massive base is made out of solid concrete it's the only way to build that time i. began got the 1st prototype in 20 jan since then we've built in erected more than 2000 wind turbines we even built the world's tallest in 2017 with the hub height of 178 meters and played tips that reach more than 240 meters. 13 wind turbines are being built in the far west of the country. the energy they'll deliver will be put to good use especially once germany's last coal powered plant

shuts down in 2038. but the expansion of wind energy is not going fast enough in many parts of the country says me learn. he's managing director of the company that operates this wind farm. this project is special from the start it's had strong support from the local authority the district and local people even the city's utility companies are involved so everything gets done much faster in places where citizens initiatives say not in my backyard it can take a lot longer. banners like this one sign of local resistance some people in the region complain that wind turbines are a blot on the landscape that's part of why it can take 10 years for a project to be approved this village is home to an active citizens

initiative. awning is already annoyed that her house is surrounded by wind turbines . now they'll be joined by more less than a kilometer away from her farm 5 months you can hear the wind turbines from a kilometer and a half away you hear them turning it's annoying that's your thought and if they're even closer when the sun comes out you'll be in the flickering shadow. but there are ways to get communities on board. had a good experience on this project he talked to locals before hand and offered them a share in the wind farms profits. this year my home is that's what they do is raise the capital for the project from local residents their sensually give us a loan and we give them back interest at a fixed rate that could be 5 percent maybe 6 percent that's quite

a lot compared to the interest rates banks offer nowadays. there are few. we asked the residents how they feel about the wind farm. as a minister i'm not bothered by it and i only see the turbines in the distance. it doesn't bother me i think it's good because renewable energy has to come from somewhere. i do understand where the conservationists are coming from when they say it has a negative environmental impact. i work in a green job myself so i can relate. but it's good that we're working towards renewable energy and building goodbye to fossil fuels. your highness pater is a farmer in the region he least one of his fields to the wind park he also bought shares in the company and will soon receive annual dividends. of tons for acceptance on the ground improves when local people are included. they get

involved with a project and say this is our project and benefits us all. we may bring you a bill energy will also. benefit from the project once the wind turbines go into operation. well they have local contacts also helps boost public acceptance and understanding. if all the older wind parks in germany were replaced with efficient ones like the country could meet all its current and actual city needs but not for long germany's electricity needs might soon double especially if electric vehicles replace gas and diesel powered ones. and building a wind farm like this is a major undertaking. this huge blades and most of the components arrive on heavy duty transporters.

the transporters are accompanied by escort vehicles the convoys top speed is 80 kilometers per hour navigating the load that's 80 meters long around a corner is a tricky operation a crew of 12 make sure. this blade was built in poland it's traveled a 1000 kilometers already. the rotor blades have grown over the years that's always been the big challenge 1st we said we'll have to stop at 45 meters then we thought we'd have to stop at 15 meters and now we have blades that are over 80 meters long. the turbine blade is a technological masterpiece and engineers are working to get even more out of them they're also trying to make the turbines more environmentally friendly and less

disruptive to people and animals in the vicinity. we use what we call dinosaurs on the. slats that help reduce turbulence and reduce noise. to help protect the environment we have. which shut down. turbines when they register bats flying nearby. have shadow sensors so when the sun shines from a certain angle nearby buildings and houses aren't bothered by flickering shadows of the dark dark they are. this blade is being mounted on to the tower today when the wind park is completed in a few months it will deliver green power to 40000 households. but new wind farms will only succeed if the people who live nearby give them the green light. here at least they found a recipe to make it work. and that's all for this man away edition of

this is. placed under surveillance by the country's domestic intelligence agency. people reportedly killed. used. to suppress protest demonstrations continue to flood the streets. of the program of germany's domestic intelligence agency has placed the country's

largest opposition party the far right alternative under surveillance the federal office for the protection of the constitution to monitor the party because of suspicions that its extremist positions could violate the country's constitution the f.t.c. says the move is politically motivated and it comes in the run up to germany's a federal elections in. september. the right wing populist e.f.t.'s flushed major triumph in 2017 when it entered the german parliament becoming the largest opposition party ever sence to f.t. has offended relishing in islamophobia racism and the glorification of germany's past. your friends and the nazis are just a bet of bird poop and are 1000 year history. some e.f.t. members openly support the xenophobic movement piggy among them extreme right wing of bjorn hooka he's the party's loaded and most aggressive anti emigrant rabble

biggest opposition party here in the bonus track after all well i guess i'm not surprised and. domestic intelligence agency has very good arguments obviously for that step. and as experience from our history we know that in a democracy. enemies of the democracy can be voted into office. and so it's a good step to to have a strong view and look closely in that corner so nothing evil can happen to germany again. what good does that do it all. from the legal point that intelligence now has more possibilities to collect information. i think here for the parliament. there will be no

actual changes but. from the reason of defending for the reason of defending the constitution. the intelligence agency has more instruments to. to collect information that might be relevant to see if this isn't party that is strongly fighting against our constitution the timing of this announcement is raising some eyebrows germany is going to the polls in september does that not feed into conspiracy theories i think it does not convince me because turning that argument around keeping it secret that you have relevant arguments for the step now and keeping that secretly before an election letting the voters not know what this important institution this intelligence service knows that could be misleading voters too so i guess it's

just the regular way things go that that right now this information comes up now that. the intelligence agency has the information to make that decision. has the possibility to go in front of chords and fight against this decision and then judges will look at the legal side and decide that's the way it goes in a democracy with the rule of law and i guess the signal is that. democracy is up to defend itself against its enemies consenting for not thank you very much thank you. for staying in germany the country's federal and state leaders are in a virtual meeting debating the next steps in the country's fight against coronavirus discussing whether to extend the current lockdown to be end of march

most of the country's non-essential shops have been closed since mid december bars restaurants the leisure facilities close their doors a month earlier ministers are also tackling the question of potentially loosening the restrictions in areas where coverage 19 infection rates are low. so take a look now at some of the other stories making news around the world police in australia have raided and have raided a factory a suspected of falsely relabeling f.f.t. to face masks in your prosecutor's office accuses hygene austria of repackaging of cheap masks from asia and selling them as austrian quality goods at a higher price a company denies the accusations and says it's cooperating with authorities to clarify the matter. an explosion at a coronavirus testing senses shattered windows in the dutch town of open karsh path 60 kilometers north of amsterdam there were no injuries of dutch police say the

explosion appears to be deliberate investigation has begun. and garion prime minister viktor orban has announced the withdrawal of his right wing feeder party from the european people's party group and the european parliament in detail the move in a letter to the a p p group chairman it follows a long running conflict with the ins legislature or $100.00 commitment to european values in the room from. the international criminal court has opened an investigation into alleged war crimes committed in the palestinian territories since 2015 it will target the israeli ministry of the palestinian militant group hamas it comes after the i.c.c. ruled last month that it did have jurisdiction. or territories occupied by israel including the west bank and gaza strip. a report from a indicate that several people have been shot dead at pro-democracy demonstrations at the latest in that deadly crackdown by the military who are feared to have killed at least 21 people at demonstrations since seizing power just over

a month ago 7 people who did as protesters clashed with security forces in cities around the country where this is and local media say police opened fire and tear gas to disperse demonstrators security forces have also arrested hundreds of journalists that dave group around me is monitoring the situation from the malaysian air capital kuala lumpur welcome dave to tell us more about these reported deaths. yes so the reuters news agency is reporting that at least 13 people were killed today it includes 3 people in yangon the biggest city 2 in mandalay the 2nd biggest city including in 1000 year old girl to the north in the community of khan and then about a half 1000 and some central communities plus hundreds of arrests made in yangon today the bottom line here with all of this is that this is a military that has no qualms with gunning down on armed civilians they see these protesters as rebels who are not following orders and they're prepared to gun more

and more down they're hoping that the desk today will just scare people off the streets and get everybody back to work and if that doesn't happen they're prepared to keep shooting more and more if they need to shoot down hundreds in a day they would be prepared to go through that if they think that's what's going to take i lived in myanmar for 7 years and when i was there i mean they had these armed at the concert in season different parts of the country and the military they would these are on the periphery so far from the big cities they would mass murder civilians they would rape scores of women and absolute impunity they are not held accountable and these are the same thing here this is have a security forces in myanmar operate. clearly processes in protesting is becoming more dangerous is that impacting the number of people who are taking to the streets or indulging in civil disobedience. i mean you can certainly expect today and some of the other you know deaths that we've seen in the past that it's going to scare some people off the streets but the bottom line is there are so many

demonstrators who have made it very clear today included that they are prepared to die for this cause if that's what it takes because they believe they have to stand up to this military government now to fight back against this 2 through peaceful demonstration that they have to fight fact because they believe if they do not stand up to this military government now any hope of having a legitimate democracy will be god for at least another generation and they do not want to live under military rule like their parents and grandparents but they're fully aware of the risks and you see a lot of the demonstrators when they march they've got on their arms their blood type and the contact information for their next of kin because they realize they may be shot. let's talk about the the army itself because obviously the generals need the obvious backing in order for this coup to succeed and it is the army completely behind the. well i'll say this memoir now an excellent news portal in myanmar is reporting that a dozen soldiers from light infantry divisions in the southern part of the country

defected left the military say they will not support this military government after all and they have photographs of some of them in uniform showing the resistance symbol right here the 3 fingers of that that is an incredibly bold call by these soldiers to do we don't know their ranks yet but if they get captured by the army they could very well spend the rest of their lives in prison but the thing you got to wonder here if there is a dozen that go through with it how many more are thinking about doing the same thing. very sobering news that for me thank you for that that dave group about. around $25000.00 african migrants arrive from the canary islands off the northwest coast of africa last year the spanish archipelago has become the european union's new migration hotspot many refugees home ready traveled on to mainland spain and other european countries though the spanish government is trying to prevent this but locals are worried the islands could become a prison for refugees t.w.

comes upon the young for the shots reports from around canaria this spot is where our muddled europe and his friend began their new life 4 months ago they had been at sea for 7 days traveling 1300 kilometers from their home in senegal to get on canada. just off the spanish coast a rescue ship took them on board and brought them here to the part of our guinea guinea in the south of the island. and since then i have no work i have nothing to do i just eat and sleep that's not what i came here for we comes to anything for our families in senegal like sending them some money for food for example 23000 refugees arrived in the canary islands last year 10 times more than in previous years they are accommodation in hotels and makeshift camps however the spanish government is working hard to prevent the refugees from traveling from the

islands to the mainland it fears this could create a new unchecked escape kori door to europe it's a clear violation of spanish law according to refugee law i haven't seen it yet and if i knew. that in spain the rights to freedom of movement within the country is classified very high you can only detain someone if a judge has ordered it if a person is not in custody they can just be detained by the authorities. if they didn't like. observe us war and that the islands have a long reach the sexual ration videos protests and clashes between locals and refugees pop up more and more on social media. and his friends for going to protests regularly they normally work as a way to us but at the moment they are unemployed to the crisis. as larry important to us to make clear that we are concerned about the end action

of our government and how illegal migration has been mismanaged we are not racists we have been living here on the island for many years with people from many different countries and cultures and 180 per cent of inhabitants live directly or indirectly from tourism in addition to the refugee crisis they are also affected by the. the worst economic slump in the last few decades due to the pandemic unemployed island us angry at the lack of support for them and frustrated migrants who perceives the island as a prison they are desperate sternly the situation on the canary islands is becoming increasingly tense local politicians are urging the government in madrid to finally start moving some of the migrants off the island to the mainland island mainland it doesn't matter to him i do geo up and his friends jump in europe is all they want but their chances don't look good despite the corona crisis spain has started the parting people with no official groan spot asylum and measure which is set to be

expanded in the next few months. i'll be back at the top of the hour with more world news came ferguson has your details me business update next day. every day counts for us and for our planet. is facing its way to bring you more conservation. how do we make see the street how can we protect.
