to the uk in the next 2a hours. in a few minutes it'll be newswatch. but first, here's click. this weekend, the world's toughest sailing race begins. held every three years, the volvo ocean race starts in alicante, in spain, and ends in the hague, in the netherlands. now, that doesn't actually sound very far. but, in the middle, there is the small matter of 16,000 nautical miles, taking in 12 cities in six continents. and, with broken masts,

capsizes and icebergs almost guaranteed, this is no luxury cruise. to try and make this journey even possible, technology inevitably raise its head. technology inevitably rears its head. these are some of the most advanced sailing yachts ever designed, and we were given special access to one of them during crew training. 22 october sees the most extreme offshore event in the world began. we're just testing if we can figure out trying to sail through that wind. we're struggling at the moment to try and make the boat go as fast as it can go, with the data we've been given. 16,000 miles, nine months of racing, seven identical boats, in the roughest seas in the world. with boats capable of 32 knots, and leaving for extended periods out with boats capable of 32 knots, and living for extended periods out at sea, races of this nature are not undertaken lightly, with crews displaying an extreme

dedication to sailing. i kind of gave up my life in france to go and do the race again, to work with the boat and to gain more experience. i sold my house and sort of made myself homeless in the process. i've got three sisters and my parents. i think i've seen my parents for five days in the last year and a half. i'm sure they would like to see me a bit more. and these experiences, as well as action from the race, will be broadcast directly from the ocean. these yachts are basically fitted with oceangoing equivalents to tv studios and edit facilities. 0k, cramped and wet versions of tv studios and edit facilities. we have two 250 antennas. one 500. satellite mobile phones can be connected to the internet via them. and there are also 36, ag modules and gps antennas.

making use of all of this kit is an on—board reporter. they have the opportunity to capture video footage, or take photographs or interviews of the teams, and then this is broadcast to the world by the on—board communication system. as the boats are being tracked live, the audience can follow the action at any time. no—one gets any sleep, and i have to wake everyone up every 15 minutes or half an hour. basically we've got to move everything on deck or below to the high side of the boat. if they really want to interact without getting wet, there is a game which uses the real race data, allowing the audience to virtually compete against the real thing. the yacht is fitted with a number of different sensors, measuring things like wind, tide speed, and how far the boat is tipping over. unusually, this event is taking place in parts of the ocean not commonly used for racing, and as a result, one of the yachts will be fitted with a sensor which checks for micro levels

of plastic waste in the ocean. this data will eventually be analysed by researchers from the un. in the meantime, the teams will have their hands full, racing their boats over massive distances. and, even though conditions will be tough, most of the crews wouldn't have it any other way. as soon as you're able to do what you love, it's not a sacrifice anymore. hello, and welcome to the week in tech. it was the week that the world's first 3d—printed bridge, made of 800 layers of concrete, was unveiled in the netherlands. facebook bought an app called tbh, that forces users to send anonymous compliments to each other. and snap shacked up with nbc to bring original tv programming to snapchat. hopefully, the shows will not disappear after five seconds. and it was a wi—fi—mageddon this week, as a crack attack exposed

a major security flaw. the weakness is found, ironically, in the security protocol used to protect the majority of wi—fi connections. some companies are already issuing patches to fix the problem, so make sure you update your systems as they come. the finalists of the global learning xprize have been announced. five teams are now in the running for the $15 million grand prize, including team kitkit school and onebillion, which we featured this summer. all have been given a $1 million award. they have been making apps. is to teach themselves subjects. finally, the $1 million duel between megabots and suidobashi heavy industry went down in japan. the us' iron glory and eagle prime won, over the course of three long, slow and painful rounds against the japanese robot kuratas, slashing it open with a chainsaw in the end. now, back to the junkyard. we have been talking a lot

about augmented reality lately. this is, in case you are not aware, the next big thing, and is being applied to all sorts of areas. this week, it is art. lara lewington has been to see how ar and 360 video is hoping to bring some culture to your smartphone. blenheim palace, a place of rich history, 18th century architecture, and a contemporary art exhibition, and that is where the technology comes into it. before speaking to our art critic about technology's place in the art world, time for a look around. artistjenny holzer‘s software combines physical installations with a mobile phone app to bring her political and historical—based work to life. beacons throughout the 200—acre estate trigger 360 videos in the right location, and combine that with your phone's gyroscope to make sure that you are looking at them

from the right perspective. here, the illusion of pictures being overlaid on the real world is created, turning day into night, eliminating buildings with words, and even appearance from a flying mythical creature. the effect looks similar to augmented reality, but is really more like virtual reality without a headset. maybe this is because bringing ar to art seems to have its challenges. let me show you this. snapchat and artistjeff koons have joined forces so users can view his sculptures through augmented reality, in popular geo—tagged locations across the world. it is hiding from us again. it is not even telling us where it is now. so, with a little help from an art critic, i tried to take a closer look in london's hyde park. there it is. there we go. the selfie worked.

having found a spot the image was tagged to, and opened up snapchat, this giant balloon dog sculpture appears on my screen. do you actually think there is a future in this? do you think people will be able to appreciate art in a different form? it's a form of reproduction of art. it's not art, i mean, it's not creating a piece. it's reproducing a piece. and i think any kind of reproduction of art does help people, whether it's a poster, or a postcard, or anything. but that's not much better than, you know, anything. but what happens when another artist wants to come and spoil the fun, geo—tagging their own work in the same place? well, new york based sebastian errazuriz has created the first example of ar vandalism. using his own app, he geo—tagged a vandalised version ofjeff koons‘s sculpture in the same location in new york's central park, which may have vandalised him,

but wouldn't affect those which may have satisfied him, but wouldn't affect those using snapchat anyway, although it does raise questions about the future of this sort of art in virtual public spaces. for a company to have the freedom to gps—tag whatever they want is an enormous luxury, that we should not be giving out for free. the virtual public space belongs to us. we should charge them rent. the meeting of art and technology clearly has its place, but whether i have seen it this week or not does seem to remain in question. ever heard of the origami inspired bot? this has been developed by mit's computer science and artificial intelligence laboratory. just like a person, it wears

different suits, or exoskeleton is, depending on the situation. this is its walking suit, very dapper. it moves around by a built—in magnets, and uses heat to change the shape of its suit. and once it is done with it, it uses water to take it off. but it doesn't end there. it is hoped that the exes buildings will be developed on a much larger scale. we have the idea of creating a robot thatis we have the idea of creating a robot that is essentially an engine that could go and pick up different coats, so to speak, they could give the robots different superpowers, that allow the robot to move faster, to scoop objects, to fly and glide, and to even float on water. potentially using them to perform different types of surgery, doing everything from patching wounds to removing objects. imagine taking the engine and swallowing it in the form of appeal, and then swallowing all

the x0 skeletons that would provide it with different tools. you now have a it with different tools. you now havea mini it with different tools. you now have a mini surgeon that can perform procedures inside your body without incisions. this could be an extraordinary future to medicine. and that is it for the shortcut of click this week. the full—length version is always up to watch online whenever you fancy. we are on twitter and facebook. we will see you soon. hello and welcome to newswatch with me, samira ahmed. allegations against harvey weinstein still hitting the headlines, the charges are serious, but has the bbc coverage been excessive? and... i'm not sure how much news this really is, but it's april... if the presenter doesn't think it's news, then why are we hearing it? first, tuesday brought the news that inflation had gone up to 3%.

like all economic data, its likely effects needed a bit of unpicking. it's good news for pensioners, who are in line for a 3% pension increase from next april. but for the working population and people on benefits, it will put more pressure on already stretched household incomes. some viewers, such as these two anonymous telephone callers, felt the bbc made too much of the contrast between the benefit gained by pensioners, whose payments will rise in line with the new inflation figure, and the negative consequences for the rest of the population. itjust seems like the bbc news is always presenting pensioners as well off and seeming like we are taking from the young, when actually i've spent my whole life looking after my whole family, and it's just really infuriating. it really does annoy me that they stir this up, because of the triple lock.

3% of hardly anything is not very much. some issues viewers contact us about do recur on a regular basis.
