of former president donald trump must be handed over to a congressional committee. unlike other recent presidents, mr trump had resisted the demand that he surrender his tax records, and the justice department had backed him while he was in office. covid—19 has critically affected pregnant women in brazil, with more than 1,600 deaths. one in five women that died from the virus didn't have access to an intensive care unit and one in three didn't have access to a ventilator. president erdogan of turkey says firefighting planes from russia, ukraine and azerbaijan are now battling the wildfires on the country's southern coast. at least four people have died and dozens have been taken to hospital. officials have promised to bring anyone responsible for starting the fires to justice. now on bbc news, click.
1:31 am
this week, we are in iceland to fly over a red—hot volcano. and then chill out with some beautiful scenery. also at a gas powered coin mine in the us. and how safe is your electric car charger from hackers? it is the land of fire and ice.
1:32 am
where the earth is literally splitting apart. this is iceland, home to so much amazing scenery, created by the superheated rock that lurks just below the surface. as recently as march this year, when new volcano has been erupting and attracting tourists and scientists alike tourists and scientists alike to watch and learn as it rewrites the geography once again. and later in the programme, we will be there to see how, as long as you're careful, volcanoes and drones can mix. now, iceland is putting all of this heat to good use. it drives the geothermal power stations which provide clean, cheap electricity, and that means now more than half of all of the cars here are a trick. the country is second only to norway in its adoption. but
1:33 am
while things are moving at a pretty fast pace here in iceland, uk is still trying to increase the number of publicly available charging points to help with the switch to electric there. and that means that home charging points are a must have for early adopters. but here's a question i bet you never asked yourself, how secure is your charger? weird question, i know, but dan simmons has been investigating how your charging point would be turned against you. —— could be. ready to plug in. well, the porsche it's thirsty and as many electric car owners will testify, having a charger at home is almost a necessity to make sure you can go places tomorrow. but all is not as it seems. because this smart charger has mysteriously switched off. next day, our man
1:34 am
is often an important meeting, no doubt. and to show off his flashy new motor. but he's nowhere because his car cannot. it's battery is still flat. his current is ok, it's the wall box charger that has been hacked and turned off. and it gets worse. because hackers can access the firmware of the second charger but to project ev, they can disable this permanently. both charges have been approved for sale in the uk by the government's department of transport. so how can this happen? well, thankfully, the good guys have found the problems first. the number of so—called white hat hikers is growing fast. these are the people who test systems and products to find flaws before anyone else does. van gillis is the hacker who found the security failures. so on
1:35 am
wallbox you could take full control of the charger. it could then gain full access and remove their unit's access on the charger. —— vangelis. it could stop them from charging their own vehicles and provide free charging to a hacker vehicle. for project ev it is way worse because you can load fenway and you can make it, you can brick it, you can make it to be part of a network and you can also make attack other servers. the problem in both cases is the lack of proper authentication between the mobile app on our smartphones often used to control these charges and the computer servers that relate instructions to the boxes. do you think it's an easy hike to

wallbox, based in spain, did not reply to us, but they did tell ken's team they had fixed the online problems. time to see if the units are safe. retesting took place this week and suggest most of the problems in both charges have been fixed. but ken says owners still need to take action. check for updates, solve the problem. the wallbox charger is —— uses hardware that is not secure enough. there's really nothing you can do to make it completely secure so unless wallbox have found a way of fixing that, which would be beyond me, i'd suggest perhaps super glowing the box cover in so hackers cannot take the top off. �* ., ., ., ,, ., ., off. and what of the approval the had off. and what of the approval they had to _ off. and what of the approval they had to be _ off. and what of the approval they had to be sold _ off. and what of the approval they had to be sold in - off. and what of the approval they had to be sold in the - off. and what of the approval they had to be sold in the ukj they had to be sold in the uk by the department of transport? and the government grants handed out to help sell them? the department did not comment on the security issues we raised but said: it's worth
1:40 am
noting that all smart home charges will still be usable if you just want to plug your car in art when it comes to security, and using them with a phone app or home wi—fi, it seems some are smarter than others. that was dan and more great work there from the white hat hikers, catching a problem before it really becomes one. now, iceland may be hot under the surface but it can get quite chilly up top. which is also pretty useful. back in 2018 we visited a crypto currency mining datacentre that produces microcomputers is huge amounts of heat with the arctic air can be sucked in as calling which eliminates the need to
1:41 am
use more electricity on chilling systems. when crypto miners realised they could get pretty cold here and electricity was pretty cheap, iceland's appeal became apparent and now crypto mining in iceland uses more electricity than the country's homes. but a long way from this country, there is a decommissioned coal plant which has been converted into a gas—fired power plant, all in the name of mining bitcoin. sounds unbelievable, doesn't it. he is james clayton. this is an energy plant with a big difference. a former coal plant, its owners greenidge generation have decided to bring it back to life, converting it into a gas—fired power station with a twist. what's happening here is part of a modern day gold rush. they are not mining minerals here, they are mining bitcoin. these computers all have one singular
1:42 am
goal that make to create bitcoin. they do that by tackling wickedly hard equations which need a lot of computer power to solve. in many ways, these computers are printing money. one greenidge —— one critter is currently worth $35,000 and all of these computers need a lot of energy. the unique thing about this plant is at both creates energy and provides bitcoin so these turbines actually create the energy and then literally right next to them, there are these massive migratory mining machines. that's the duty of this, it is all done in house. mining bitcoin is usually energy intensive and cambridge estimates the annual amount of energy used to my bitcoin is equivalent to a country the size of colombia or bangladesh. there are nearly 10,000 bitcoin mining computers here and greenwich wants to build more.
1:43 am
the company argues it is greener than bitcoin mines that use coal in the us and china and that they off their emissions but there still pumping out carbon dioxide to make a crypto currency. i spoke to greenwich's chief executive geoff kurtz. people would think it's absurd but at a time when a lot of people are trying to cut down on their carbon emissions, there is a plant that uses fossil fuels to mind bitcoin —— kirt. that uses fossil fuels to mind bitcoin -- kirt.— bitcoin -- kirt. first and foremost. _ bitcoin -- kirt. first and foremost, we _ bitcoin -- kirt. first and foremost, we are - bitcoin -- kirt. first and foremost, we are 100%| bitcoin -- kirt. first and - foremost, we are 10096 carbon foremost, we are 100% carbon new —— neutral in our operation and we are the only company

hello and welcome to the week in tech. it was the week twitter started testing a new online shopping feature. the play date hand—held gaming console became available for preorder. and after his return to earth, amazon billionaire geoff baeza was offered nasa $2 billion to reconsider the awarding of a $2 billion contract to spacex. also this weekjoe biden said a cyber attack on america could lead to attack on america could lead to a real shooting war. the president was speaking with members of the us intelligence community. resident biden�*s remarks follow recent high—profile cyber attacks that affected parts of america's food supplies. the start—up has beaten elon musk�*s link company to clinical trials in the race

to clinical trials in the race to plant computers in the human brain. the company announced they would undergo human trials in new york later this year. google is saying its u.s.—based employees returning to work this autumn will need to be vaccinated. facebook quickly followed the search engine's lead saying their employees would also need to be vaccinated to return to the office. and finally this week we saw for the first time and untethered, bipedal robot complete a five kilometre run. the robot called cathy finished the journey in 53 minutes. cathy was designed by a team of researchers from oregon state university. it taught itself how to run on outdoor terrain using machine learning, and made it through on one battery charge. sadly i couldn't make it tojoin spencer charge. sadly i couldn't make it to join spencer in charge. sadly i couldn't make it tojoin spencer in iceland, but in the traditional sense anyway. —— not in. iam heading there in virtual reality though, for a spot of

it is nice to escape to other worlds when we are meditating because it takes us out of the stress of the day and helps to calm the mind, where you can just breathe and focus. technology medication are a little bit like contradictory but at the same time, we need to put more wholeness, more meditation, more health and wellness into the technology so the technology can serve our well—being and our best, you know, highest purpose. the total icelandic _ know, highest purpose. the total icelandic immersion, the 3pp total icelandic immersion, the app features local musicians like sigur ros. i app features local musicians like sigur ros.— app features local musicians like sigur ros. i used to play computer — like sigur ros. i used to play computer games _ like sigur ros. i used to play computer games and - like sigur ros. i used to play computer games and i - like sigur ros. i used to play computer games and i was l like sigur ros. i used to play computer games and i was a j like sigur ros. i used to play - computer games and i was a kid, i still do actually, and kind of felt this was almost like a cheat code to meditation in a way. it brought me somewhere immediately rather than taking time to get into. when we are writing the music it is kind of

1:51 am
have introduced in a long time. because scientists are using volcanoes to research how to deploy drones on mars. need i say more? my my name is christopher hammerton, iam my name is christopher hammerton, i am a associate professor at the university of arizona and a planetary vulcan ologist. we are here at a new volcanic eruption that has occurred in southern iceland. iceland is an ideal testbed to create different drones for mars because they are wonderful characteristics of the environment are actually very similar to what we would expect on mars. this has been a really exciting year for mars exploration. the drone ingenuity has demonstrated flight on mars for the very first time, being able to operate in a very thin atmosphere, about 1% of what the earth �*s atmosphere is. but it was ultimately limited in terms of the instruments are carried, basically cameras. the
1:52 am
next generation of mars drones will be able to have a range of other capabilities. small drones offer a lot of advantages, they are lightweight, they do very well in relatively high when and they can be used and carried to rather extreme environments. —— high winds. if something catatonic happens with them, the cost aren't prohibitive. it lets you test things in ways you wouldn't necessarily be able to do with a larger system. i think that is about the fastest spot right there. some people have even taken small drones and flown into the volcano, acquiring phenomenal imagery, destroyed in the process but really beautiful to watch. it process but really beautiful to watch. , , , ., watch. it is still giving you that warning? _ watch. it is still giving you that warning? no. - watch. it is still giving you that warning? no. the - watch. it is still giving you i that warning? no. the other drone we — that warning? no. the other drone we are _ that warning? no. the other drone we are using - that warning? no. the other drone we are using has - that warning? no. the other drone we are using has a - that warning? no. the other i drone we are using has a larger payload, a number of different cameras and zoom functions, really beautiful, but also a lidar instrument. lidar uses light to be able to arrange the distance between a sensor that
1:53 am
is emitting a set of photons and the surface. it is a world first to be able to use a drone base lidar to image the lava flow and used time lapse photography in order to determine the thickness of lava, the volume, and the amount of lava coming out of the volcano at a particular time. we have been working with students from the university of arizona and also the university of iceland and the reykjavik university and they are doing a greatjob being able to develop some new experimental types of drones which are able to push the edge of what has been done. this large drone is obese, it has 26 horsepower motors and over 1.5 metres wing tip to wing tip and is able to lift potentially 35 kg. today we are mainly trying a thermal infrared camera which measures the temperature of the lava which is a first for us to be able to do from the air with this system. even though we don't see with our eyes we can actually map out regions that are hot and potentially having lava throwing —— flowing underneath the crust. we are
1:54 am
also testing a claw that can be used to pick up loose examples, but also drills that can actually core a sample using the drill and bring it back to a lander or even a roverfor further analysis. the different drones and instruments, the different mission concepts we are putting together will enable new exploration of the red planet and to see parts of the planet we have never seen before, and i hope we will have an opportunity perhaps in the coming decade to send a drone dedicated to exploring mars's volcanoes and for the first time see if potentially they are harbouring evidence of life. past or present. are we alone in the universe, but also added we begin potentially, what is the world like in the future that we will come to inhabit as well? absolutely spectacular. that was christopher hamilton and thatisit was christopher hamilton and that is it from us for the moment. don't forget, you can follow our exploits on social media, we are new to, facebook, instagram and twitter. thanks
1:55 am
for watching and we will see you soon. —— we are on youtube. well, friday brought quite a nasty spell of weather to some south—western and southern areas of the uk. gale—force winds around coasts briefly. they were very, very strong indeed, brought by storm evert. you can see on the satellite picture here thunderstorms and heavy showers inland, generally a really changeable day, but the weather has now shifted into the southern north sea. it's approaching parts of germany and denmark. behind it, you can see from the motion of the arrows, it's a fairly cool north—northwesterly, so it's going to be a fairly cool day for most of us. really quite nippy, in fact, in the very far north
1:56 am
of the country. sunny spells and showers expected. so, let's have a look at the early morning hours. that northerly wind blowing across scotland and along the north sea coast. showers there right from the word go, but i think showers are possible almost anywhere early in the morning, apart from the extreme north west of the country here. temperatures a little on the fresh side, around 12—13 degrees in some spots. and then, tomorrow, a pretty cloudy day for many of us, in the morning at least, to start with. then the sunny spells develop, but also the showers, and some of them will be heavy. you can see here in the east of the country and the north, some thunderstorms there, too. showers also breaking out across the south. the best of the weather, i suspect, in the north—west of the country, parts of northern ireland, south—western and western scotland and also cornwall, devon and southern wales shouldn't do too bad on saturday. here's a look at sunday's weather map. the weather still coming in from the north. we have a weather front crossing the country. that is expected to bring showers to more southern areas
1:57 am
of the uk on sunday. they should be more confined towards the very far south towards the end of the day. that's how the end of the day starts, so a little on the chilly side in some areas. those northerly winds, feels quite nippy along the north sea coast, could even be around 111—15 degrees during the daytime. best spots, i think, in southern wales, maybe northern ireland again, but i think in southern wales and cardiff, up to around 21 degrees or so. so, here's the weekend summary again, and the outlook into next week, not an awful lot changes. there's no warm weather on the way. i think it's going to stay more or less the same, below average and a chance of some showers. and that's it, bye—bye.
