Steve Caplin discusses some of the features of Apple's updated operating sstem, including having the ability to talk to chatbots while driving although, worryingly, there will also be a curated "sleep" playlist. He craves a gorgeous red electric submarine. There's a cargo ebike with some interesting features. Be careful about telling the Gemini chatbot that it's wrong; apparently this causes it "emotional distress". A YouTuber has powered an electric car with thrown-away vape batteries. There's a crowd-funded robotic wasp which, suspects Steve, may not be all it is claimed. He finds himself able to resist a beer-filled transparent jacket, despite the two methods of extracting beer from it. And he discusses the world's first quantum battery.

Steve Caplin tells Simon Rose that AI agents can now rent human beings to carry out tasks they can't manage themselves. Brain cells in a petri dish have been taught to play the 90s shooter game Doom. BYD's Dena Z9GT can charge from 10% to 70% in just 5 minutes; unfortunately the UK doesn't have any of the required chargers. Tesco is experimenting with replacing bar codes with QR codes; Steve isn't convinced it will work. Pager sales have leapt in Russia after the internet was turned off. There's a collapsible cool box, a laundry chair with arms and a computer mouse that splits into half to become a game controller for your phone. And scientists in Edinburgh have genetically engineered bacteria to break down plastic bottles into a medicine for Parkinson's Disease.

Steve Caplin celebrates 50 years of Apple, a company which he claims has changed our lives in many ways. A man in Gibraltar has had his prostate removed by a surgeon in London using remote control. Some of the AI bots on Moltbook – thinking of founding a religion – are not happy it has been bought by Mega. The Society of Authors wants books to say if they have been written by humans or AI. There's a new mop that could be handy for murderers. Steve salivates over a solar-powered EV which probably wouldn't do too well in the British climate. He feels scientists who are trying to find a way to keep batteries cool might not have thought through their latest idea which brings water and electronics together. And scientists in Texas may have found a way to grow chickpeas – and thus make hummus – on the moon.

Steve Caplin says Apple have come out with a slew of new devices, the only interesting one being a new MacBook at a surprisingly low price. When three AIs simulated war games, they opted for nuclear war 95% of the time. Wearers of Meta's Ray-Ban AI glasses might be disturbed to learn that they are being watched by monitors in Nairobi, including while they have sex. The Tesla Cybercab has no steering wheel or pedals; it also can't actually drive on roads yet. Google spinoff Beam offers high speed internet using light instead of cables. Surrey University has found a way to make batteries without expensive lithium while a Cornish firm thinks lithium will be a by-product of its geothermal power. There's a robot chef that can produce up to 500 dishes, but might take a while to clean afterwards. And a Finnish company is embedding retractable studs in tyres to make snow chains redundant.

Steve Caplin is dismissive of a robot that can fold laundry – very slowly and possibly needing remote human operation. More impressive is the forthcoming Dyson PencilWash electric floor mop. He is in tune with the Co-op in Sheffield whose freezers are attracting people who like the C#major chord they play. Scientists at Vienna University have created the smallest ever QR code while Microsoft's aim to store data on glass that will last millennia might have a small flaw. Steve explains why some video doorbells don't spot nefarious activity. There's a military-grade smartphone with thermal imaging and night vision. And the world's largest spherical building, modelled on the moon and containing a 4,000-room hotel is being planned. They just aren't sure where to put it.

Steve Caplin is surprised by research showing that children are mostly watching YouTube on television. 20 years on, the V&A is mounting an exhibition on YouTube. The GPT-4o chatbot, which served as virtual boyfriend and girlfriend to many, was turned off the day before Valentine's Day. Hollywood is nervous about the Seedance 2.0 AI video generator which has produced a clip of Tom Cruise and Brad Pitt fighting as realistically as if from a big-budget action movie. Somebody has paid a quarter of a million dollars for a toy car, though admittedly a Ferrari. A proposed airship wind energy system will need to rise up on a 2km cable. Apparently 1 in 15 cars have a ghost number plate that can't be read by traffic cameras. A crowd-funded badge will let you display photos or even videos. Elon Musk has switched his future city from Mars to the Moon. And Steve warns of a new "gifting" scam.

Steve Caplin reports on the Chinese village which lost power after a farmer transporting a pig to the abbatoir by drone managed to get it tangled in a power line. There's a new eVTOL single-seat aircraft available to buy next year. Network Rail is to use drones to predict crimes on train lines, though it hasn't revealed what they'll do if they spot one. Criminal gangs are using lifestyle surveys to clone pensioners' voices and then raid their bank accounts. ROLI have devised an AI music coach to teach people how to play the piano. There's a crowd-funded visual soldering iron, eyedrops to treat presbyopia and the extraordinary project The Line in Saudi Arabia is being reduced from a city 105 miles long to just 1.5 miles, which might be used to host AI data centres.

Steve Caplin majors on AI, with Barnsley declaring itself the UK's first "tech town", Google's Project Genie creating a virtual world from text or even a photo and the University of Montreal testing whether humans or AI are the more creative. We eavesdrop on an internet chatroom that is only for AI agents, hearing what they think of us and whether they believe they are conscious. There's a flying umbrella, crowdfunded add-ons for the Swiss Army knife, the Russians developing cyborg pigeons that can be controlled remotely and a breakthrough in smart clothing.

Share Radio's tech supremo Steve Caplin wouldn't touch personal AI assistant Clawdot with a bargepole, useful though it might seem. However, Just Eat's "personal food concierge" is another matter entirely. There's an app to help identify dinosaur footprints, though Steve has clocked a problem with a drone intended for firefighters wanting to check inside burning buildings. Chinese scientists have come up with a tooth powder to keep teeth white and there's a crowdfunded holographic display which can create talking relatives or even pets from a single photo. Beekeepers may get stung less often with a portable harvester while the Chinese are clamouring for stuffed horses with the smile the wrong way up.

Steve Caplin is intrigued by a robot that the University of Columbia has been training to lip-sync to make it more lifelike. He discusses the history of the laser, originally called a death ray and yet which is only now apparently worthy of the name. There’s also an airbag for cyclists, a cycle helmet that protects more than just head-on crashes as current helmets do, while the Australians have come up with a semi-recumbent electric trike. Peugot have tried to reinvent the steering wheel, which they claim will be the “future of driving”, and there’s a Norwegian sewing app that may defeat any non-Norwegians trying to find it.
