Boiling point: Tech and the perfect cuppa

Smart ways to let off steam

Review Last week, coffee drinkers were treated to some alternative brewing techniques. So, is there any special gadgetry for those with a taste for tea? Jennifer Newton discovers there’s more to letting off steam than meets the eye.

Smart: perhaps one of the most overused words in the modern lexicon is now being bandied about in the world of kitchen gadgets. While most of us are used to the idea of that moniker being applied to connected appliances in the home, it seems that, in the process of domestication, "smart" has been dumbed down a little.

Some kettle manufacturers have used their smarts and are getting in on the act. The claims of cleverness aren’t entirely hollow either, as there are some rather nice touches that add sophistication and elegance to that most British of activities: making a cup of tea.

The boiling tap is a smart option too and has recently come down in price (more on this below), but first up for cost-effective must-have tech appeal are some of the hottest kettles for both the terminal slob and the domestic god.

Bubble chambers and boil treatments

The perfect cuppa requires boiling water at 100°C, as any Englishman abroad will attest: sometimes one has to send cup after cup of tepid tea back to the hotel kitchen. Seasoned tea drinkers will also know that green tea should be brewed at 80°C, Oolong at 90°C and instant coffee at 95°C. Who knew or cared 20 years ago?

The perfect cuppa: always a case for heated debate

Essentially, temperature control is the "new" feature to look for – along with a keep-warm function of 20 minutes or more. All of the models listed below have this addition apart from the Kitchen Aid Artisan. Depending on overall capacity, the higher wattage kettles will, in theory, boil water faster, with 3kW classed as rapid boil.

Kettles learn to play it cool

If you plan on being smart in the practical sense of the word, then a push-button lid makes for easy filling and going cordless with a multi-directional base works out well for households with a mix of right- and left-handed folk.

Bosch Styline TWK8633GB

The Bosch Styline has four temperature settings (70°, 80°, 90° and 100°C) with an accompanying LED indicator for that range. At £55, it’s a reasonable price and the black, blokey exterior design makes it look like a pint of Guinness. That said, when it comes to taste, that slightly plasticky build fails to "wow", even though it is robust.

By contrast, the white and brushed steel version does look good and both have cool touch housing. As with the AEG and the Sage, you get a rude bleep alarm to tell you when the kettle has boiled. You’d have thought Bosch could have provided a choice of whistles or a Tea for Two ringtone instead. Maybe that's lined up for next year's smart craze.

  • Robotics and 5G to spur growth of SoC industry – report
    Big OEMs hogging production and COVID causing supply issues

    The system-on-chip (SoC) side of the semiconductor industry is poised for growth between now and 2026, when it's predicted to be worth $6.85 billion, according to an analyst's report. 

    Chances are good that there's an SoC-powered device within arm's reach of you: the tiny integrated circuits contain everything needed for a basic computer, leading to their proliferation in mobile, IoT and smart devices. 

    The report predicting the growth comes from advisory biz Technavio, which looked at a long list of companies in the SoC market. Vendors it analyzed include Apple, Broadcom, Intel, Nvidia, TSMC, Toshiba, and more. The company predicts that much of the growth between now and 2026 will stem primarily from robotics and 5G.

  • Deepfake attacks can easily trick live facial recognition systems online
    Plus: Next PyTorch release will support Apple GPUs so devs can train neural networks on their own laptops

    In brief Miscreants can easily steal someone else's identity by tricking live facial recognition software using deepfakes, according to a new report.

    Sensity AI, a startup focused on tackling identity fraud, carried out a series of pretend attacks. Engineers scanned the image of someone from an ID card, and mapped their likeness onto another person's face. Sensity then tested whether they could breach live facial recognition systems by tricking them into believing the pretend attacker is a real user.

    So-called "liveness tests" try to authenticate identities in real-time, relying on images or video streams from cameras like face recognition used to unlock mobile phones, for example. Nine out of ten vendors failed Sensity's live deepfake attacks.

    How? Founder tells The Register 'Robots… lots of robots'

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."
