this is bbc news. the headlines: there is growing concern that a power struggle between saudi arabia and iran is fuelling the political crisis in lebanon. the american secretary of state has warned other countries against using the country for proxy conflicts, following a crisis triggered by the resignation of its prime minister. one of the latest figures in american entertainment to be accused of sexual misconduct, the comedian louis ck, has admitted that several allegations made against him are true. five women had accused him of various acts of indecency. in a statement, louis ck expressed remorse for his actions. the european union's chief brexit negotiator has said the uk has two weeks to clarify what it will pay when it leaves if it wants talks to move onto a trade deal at december‘s eu summit. michel barnier also said there were issues around the irish border that needed to be resolved. now on bbc news, it is time for

click. this week, caveman, moon rabbit, space turtle! welcome to china, to shenzhen. believe it or not, this place was once a small fishing village. yeah... notany once a small fishing village. yeah... not any more. now it is a mega— city of nearly 20 million people. it is most famous for creating consumer electronics, often imitations of premium devices. but

as china has opened its doors to international trade in the last decade, it has undergone a transformation, making strides toward becoming a global power and moving away from the image of being a simple manufacturer of good, fake or otherwise, to one of innovation, especially technology. made in china is fast becoming designed in china. next week, we will visit some of the companies that call shenzhen home, but this week, we are meeting this quy- but this week, we are meeting this guy. this is little cloud, and recently, he has gone where no total has gone before. he hasjust completed a test flight of a journey that one day might take humans to near space. this is the traveller project. we have seen this kind of

stratospheric helium project before. we visited world view back in february in the us to see their enormous inflatable.” february in the us to see their enormous inflatable. i think you have the world's biggest table. and a spanish outfit, zero to infinity, is also trying something similar. so why does the travel project was made director feel he can beat them to it. we want to be the first one. we need to try hard to become the first one. because, in shenzhen, the environment is very good, and a lot of people want to do big things. the government supports us. so, i think that shenzhen gives us a very good environment to accelerate the progress. the secret, - is progress. the secret, though, is also in the science. the balloon

material looks quite ordinary, but of course, it is not. it is a special kind of polyethylene which has to resist the damaging effects and ozone. it needs of ultraviolet and ozone. it needs to be able to stop the really, really tiny molecules of helium from escaping. this kind of space tourism is billed as being cheaper and safer than rocket —based alternatives being trialled by virgin galactic and spacex. normal people, even older ones, can do this. you don't need a suit. you must be very strong to be an astronaut and trained for many days and years. however, this does not need that. why did you choose a total. that is a good question. —— turtle. because the turtle has a long life. sometimes it

can be living for more than 100 yea rs! can be living for more than 100 years! the turtle can live in water, it can in an years! the turtle can live in water, it can - in an environment it can survive in an environment without oxygen. is a cruel to send a total up there? hmm... what without oxygen. is a cruel to send a total up there? hmm. .. what can i say? total up there? hmm. .. what can i 7 i total up there? hmm. .. what can i say? ijust total up there? hmm. .. what can i say? i just say we need total up there? hmm. .. what can i say? ijust say we need to do this kind of experiment before human beings in the near space. i need to beings in the near space. we need to pick upa beings in the near space. we need to pick up a kind of animal. hmm. .. well, as usual, not a great life being an animal involved in human exploration. while these guys are busy trying to win a race to space, others are trying to put a rose on the moon. unfortunately, this time, it is not a real dog. —— you may

remember we visited the indian team start—up, indus. they are one of five teams competing for a 20,000,000-dollar five teams competing for a 20,000,000—dollar prize if they are the first company to land and strive a robot on the moon. —— drive. and one thing we learned while we were there was that to save costs, they are sharing with a japanese competitor, ispace. now we are paying them a visit. this is the space suit. and this is a hammer to break something. 0k. well, with the important stuff out of the way, time to talk space. what inspired you to enter this challenge? to talk space. what inspired you to enter this challenge ?|j to talk space. what inspired you to enter this challenge? i have always been interested in space. however, someone said there was a lunar race,

why not help? it may be a small operation, but what they lack in size they certainly make up for in style. it is notjust the skyhigh rents of tokyo responsible for the diminished dimensions off of the tokyo office, it is also because of the planned to hitch a ride on the tea m the planned to hitch a ride on the team indus ship means they only have to build the brother. a —— rover. they are trying to create it so that it does not collide with anything. it will be steered and moved one step at a time to give everyone time to think as it gradually moves across the surface. mind you, you still need the very best pilots and technicians in the business to command and strive this thing. seriously? 0h,

command and strive this thing. seriously? oh, man! this isjust a demo for numpties like me to use, but the real prototype is being developed just across the office. that will be the one that actually goes to the moon, well, if nothing goes to the moon, well, if nothing goes wrong, say, buy, letting me touch it. —— by. it is so light. just four kilograms. remarkable. touch it. —— by. it is so light. just four kilograms. remarkablelj just four kilograms. remarkable.” amjohn just four kilograms. remarkable.” am john walker, the chief engineer. the worst thing that can happen as we go to the moon and for whatever reason we don't get any function. we are trying to win, but at the end of the day, we want to keep going back to the moon again and again. so we need that starting point, we need data. we need simulations. that is why a huge part of the mission's cost goes towards testing, and that means rigourous testing on the wheels, control systems, electronics, and perhaps most

crucially of all, the communication system. of course, it is notjust tea m system. of course, it is notjust team indus and hakuto in the competition, there is moon express, and synergy moon, made up of six continents. they all have contracts, but when they take off is anyone's gas. it is very secretive. -- guess. what happens if you find out they launch in november. it is possible. however, it is very difficult to launch without any notification beforehand. so i am still very... i am sometimes nervous when they will make an announcement. just like the other teams, ispace is about more

than just other teams, ispace is about more thanjust one other teams, ispace is about more than just one mission to the moon. they are hoping that the data they gather and the skills they learn could have much more profound complications after the mission whether they win or not. we recognise this race isjust whether they win or not. we recognise this race is just the start of everything in the future. and we think that the moon is the best place to mine resources and that includes dual in space. this is the first step for this establishment. there is certainly a loss that could go wrong. besides the perils of space, they still need to spend a huge deal of cashier on earth before anything can take off. —— cash here. one thing is for sure, though, we are so excited about this race to the moon. but what has become apparent if it is notjust

about getting their first, it is not just about the prizemoney, it is just about the prizemoney, it is just as important to get data back and build up this knowledge to be able to go there again and again and again in the future. and when these quys again in the future. and when these guys launch, we are going to bring back to you. —— that. this week in the tech world, a british inventor set the first world speed record for flying a body controlled jet engine power suit. richard flew across a la ke power suit. richard flew across a lake in waiting reaching 22 miles per hour. snapchat finally admitted those specs where a mistake. after selling over 150,000 of them. and weimo have admitted they are getting rid of the human safety drivers that usually sit in the front in case khazanah usually sit in the front in case khaza nah function, there usually sit in the front in case khazanah function, there will however be a human sitting in the back of the car for the time being

at least. an autonomous vehicle in las vegas crashed last week on its first day. it recognised the vehicle in front of it and stopped, but the human driver did not, hitting the shuttle. silly humans. a robot has been designed that can summon and operate elevators. it has been described as a good robot. they want the skills to be used for search and rescue missions in the future. it is not 2017 without a robot that can call a left. and in 2017 fashion, uber announced they have joined forces to build autonomous flying taxis. they say they will be com pletely taxis. they say they will be completely electric and will be used at the 2028 olympics in los angeles. we will see. that is pretty good. but this week,

i have been taking a look at some technology that aims to question your perception of taste. here at the university of sussex, levitating food is being served up. yes, that is right, liquids and solids can float in the near before being directly fed into your mouth. —— thin air. it works through high frequency sound that traps food in midair. the idea being that the heat generated by the sound waves could make flavour more intense. i put it to the test trying identical samples of each taste from the device. it

tastes sweet. sorry, there is no delicate way of doing this. did you get it? yes, and i would say that that was more intense. wow. this time, igot that was more intense. wow. this time, i got it, and it tasted very sweet. i i think it is sweet and cereal. considering how small the pieces work, i did not get much flavour. —— were. i was concentrating more. it is an interesting case experience in the laboratory. i know you want it in the real world to make it possible for a chef to make something and then directly transfer it into somebody‘s mouth. then directly transfer it into somebody's mouth. that is the inspiration. we are trying to figure out how to do that. i can show you it now. this mimics the

presentation. when the chef is finished cooking, he puts it in one side and he can control it. like how fast you release the item. it makes ita fast you release the item. it makes it a desirable experience. if you feel a desperate need to amaze your guest with tacky astronomy, you might be interested in this! this is a 3—d liquid printer. it is a lots more than most of the 3—d printers we have shown you, and it will create a substance that look something like this. a small, edible bite in eight caviar like consistency. —— a caviar—like. this is passionfruit, but you can use any sort of natural ingredient to create intense flavours, and the app will guide you through what flavours might go together. inside the machine right now are some concentrated passionfruit. for the

sake of demonstration i am going to try to create something that looks like a berry but tastes like passionfruit. maybe i will impress my guests with it. let's give it a go. i create the shape that i want here on the app. the phone is connected by bluetooth to the device, so to get it going, ijust press the blade button. that took under five minutes to come together. quite fascinating to watch. as the in i watch. as the pieces went in i wasn't convinced they were going to stick together. the structure is not perfect,, i will stick together. the structure is not perfect, , i will admit, stick together. the structure is not perfect,, iwilladmit, but stick together. the structure is not perfect,, i will admit, but the big question is, how does it taste? it is just question is, how does it taste? it isjust made of question is, how does it taste? it is just made of passionfruit, so it should taste like passionfruit. which it does, but rather than tasting of concentrated passionfruit, i would say that actually tastes a bit die looted. that is probably because some of the water is with it. however flavoursome, or not, the device's creations may have been, in their current form they do not muster up a great deal of food. so i did finish

filming, rather than looking forward to lunch. welkin to be seg electronics mega market in shenzen. —— welcome to be. it is one of many in asia, and it is here that you come to buy anything and everything electronic. this is also where you can bulk buy new components manufacturer and new device. this is we get lithium ion batteries for your laptops, smartphones, anything, really. what if you didn't need these at all? we created the first battery free phone, which harvests in a power from ambient light and ambient rf signal so that we can completely power the whole phone byjust ambient rf energy. and elemental batteries. you can make a phone call

to another cell phone or another landline. by stripping back components to the bare minimum, vamsi and his team have successfully made calls over skype. they take advantage of something called analogue back scatter, which reflects pre—existing waves found all around us to communicate a message. right now this only works in the laboratory, but the team are working on improving its range beyond ten metres. for the moment, batteries do thejob. beyond ten metres. for the moment, batteries do the job. but we all wish we could charge that little bit faster, and last longer. especially when it comes to electric vehicles, which takes several hours to charge. and the race is most definitely on. japanese giant toshiba has just unveiled a prototype of its next—generation supercharged ion battery, made of a unique material. the company claims this battery of

titanium oxide will charge injust six minutes, and deliver a range of over 200 miles on a single charge. but it will be a couple of years yet until we see real results. and in the event of a natural disaster, being cut off from the grid is something that can be life—threatening. after the petter rico disaster, kaesler boss elon musk stepped in, offering a free battery grid for a hospital on the weatherbeaten island. —— puerto rico disaster. he is also halfway through his 100 day challenge to install the world's three grid in australia. tesla says so far, so good. but it isn't all rosy for elon musk. recent production of his model three car has stalled due to battery installation is use. 0nly has stalled due to battery installation is use. only 222 vehicles were built in this year's third quarter, way below the 1500 targets, leading to lawsuits and drops in share value. but how about

this? a battery made their —— made ofair. yes, this? a battery made their —— made of air. yes, air. this? a battery made their —— made ofair. yes, air. deep in the this? a battery made their —— made of air. yes, air. deep in the swiss alps, there is a solution which could be about to be rolled out to the masses. nick kwek took a deeper look. i am on my way to this guy's batcave. no, he is not the swiss bruce wayne. he has a cave that acts like a bruce wayne. he has a cave that acts likea giant bruce wayne. he has a cave that acts like a giant battery. this is the mountain where our plan to space. while. yes, quite enormous. i am being given a of his being given a private tour of his prototype powerplant being given a private tour of his prototype powerpla nt harnesses being given a private tour of his prototype powerplant harnesses the power of compressed air. welcome to our tunnel. 0h, power of compressed air. welcome to our tunnel. oh, my goodness. yeah. we drive now 700 metres. that is where the plant begins. so we are not actually going deeper underground? we are just going

further into the mountainside? exactly. the further you get into the mountain, the more rock and mountain is above you, so we can hold the pressure that you are building in the planned. —— plant. the system works by pumping air into the side of a mountain and storing it tight me until there is a demand for electricity. like a battery, it springs into action when you need power, releasing the air rapidly through turbines which generate the electricity. here we already have the hard, compressed air, flowing through the sprites. as you can see, thatis through the sprites. as you can see, that is quite insulated. we have the valves to control the flow, and on the other side you can see that pluck, closing the plant. -- plaque. soaring energy harvested from renewable sources to use later means we can have electricity when the sun

is down or there is no wind. this is where the magic happens? yeah. this is the first plug, 100 metres, 120 metres down the line, we have the exact same plug, to seal off the two ends of the chamber. it is 6.8 tons. pretty easy to move, then. that put your strength to the test. my goodness. that's crazy. do not want to be in here when it is filled up with all that hair out. —— that air. there are already two function in power plants which utilise existing compression tack. 0ne power plants which utilise existing compression tack. one in germany, and one in the united states. but this system has improved efficiency by over 30%, and the secret behind it is this giant concrete block. and what is inside it. so all that hot

hair that is piped in, what is inside it. so all that hot hairthat is piped in, it what is inside it. so all that hot hair that is piped in, it comes here to the thermal chamber. —— what air. that is chock—a—block full of 75 tons of gravel. as the air comes in, it cools down, because the transfers that each to the gravel inside. the cold air comes out of this hole in the ground, which fills up this massive, 120 metres long tunnel. it is stored here until there is a need for power, at which point a valve is opened and the air rushes back through the gravel, reheating and expanding in the process, so it is warm enough to safely turn be turbines. that is the kicker. we can increase the efficiency of the system increase the efficiency of the syste m fro m increase the efficiency of the system from the 40% of existing plants, to above 70% in our case. this prototype only generates 1 megawatt of energy, which is a tiny fraction of the several 100 found in regular size powerplants. fraction of the several 100 found in regular size powerpla nts. and fraction of the several 100 found in regular size powerplants. and you need a mountain with a ready—made cave children to decide for it to

work. this current prototype could potentially power 100 homes for one—hour, with one k of discharge. —— to three mac. it is scalable, which means that if you scale the top 100 times, it could power a nearby city for half a day. we are hoping to commercialise it. it can absolutely be a component of the national grid or even the european grid. this technology is not limited to switzerland. it will be applied in other places around the world, where it is necessary to dispatch the production and consumption of renewable energy. that was nick. we will have more from shenzen in next week's programme. here is a thing. if you have ever wanted to meet us and see us perform live, you are in luck. make a note of this address. this is where you go to get tickets for the forthcoming click live show, which is happening very soon. you will be able to say hello to us, and you can also experience some of the things you've seen on the programme

lives. tickets are running out, so that's where you go. do it now. we look forward to seeing you there. thanks for watching. we will see you soon. hello. contrasting fortunes across the british isles for the weekend. first of all in the west we have imported the remnants of tropical storm rina as moist air, but that means a lot of cloud and some rain across much of england and wales and parts of northern ireland. further north the air has come from the north, hence these numbers — 2—4 degrees. there is some sunshine but it's doing nothing for the feel

of the day and for the temperatures. this is how we shape up in the middle part of the afternoon. there will be some showers across northern and western parts of scotland. that's been the way of it for a few days. dry and bright weather in the central belt and towards eastern parts of scotland and across the board into the north of england. eventually and slowly we have brighter conditions getting into east anglia. anywhere back towards the south and west, go too far and it is just rain all the way for the greater part of the day. towards wales later, it doesn't matter what time of day, wales versus samoa will be wet. the rain pops up as a wave when a weather front comes through into the small hours of remembrance sunday. further north, skies will be clearer and temperatures as a consequence will fall away. a touch of frost. plenty of showers from the word go on remembrance sunday around the shoulders of the british isles. largely affecting the coast. we are all exposed by sunday to the cold blast, as the weather front pulls away. on sunday, bright, crisp and sunny. a scattering of showers as well. it will feel markedly colder.

the top temperature on the day, 9—10 degrees. in the next week we start on that theme of cold and frosty and it then turns milder in the middle part of the week and there will be some rain in the forecast. a bright, crisp, frosty start for many into monday and then we have the first signs of that change getting to the north—west of the british isles, with milder weather on the way.
