Flying Selfie Bots: Tag-Along Video Drones Are Here

In last year’s January tech issue, I focused on the disturbing threat to privacy that unmanned aircraft seemed to pose. Who, after all, would want to be stalked by a small, camera-toting drone that was recording their every move?

Seems I got that one wrong. Plenty of people—sports enthusiasts in particular—are ravenous for selfies taken by aerial robots. And start-ups everywhere are now scrambling to develop this technology for them.

Carbon-Removal Tech Grabs Elon Musk’s Check

Millions poured into XPrize effort to pull CO2 out of the sky

London’s Mission Zero Technologies has developed an energy-efficient way of capturing carbon dioxide from the atmosphere and sequestering it into the dominant rock (peridotites) of the upper part of the Earth’s mantle.

Stretching across the northern coasts of Oman and the United Arab Emirates loom the vast jagged peaks of the Al Hajar mountains. The craggy outcrops are made mostly of a rock called peridotite, which absorbs carbon dioxide from the air and turns it into solid minerals. The mountains could store trillions of tonnes of human-made CO2 emissions, but the natural carbon-mineralization process works at a glacial pace.

London startup 44.01 has found a way to speed it up. For this endeavor, 44.01 is teaming up with another London startup, Mission Zero Technologies, which has developed an energy-efficient method to capture CO2 from air. Called Project Hajar, it plans to pull 1,000 tonnes of CO2/year from air at a demonstration facility in Oman, injecting some 3–4 tonnes/day into the peridotite rocks. A 120 tonne-capacity pilot plant will come online in the first half of 2023.

What Is Wi-Fi 7?

Great capacity, less latency—here's how IEEE 802.11be achieves both

New generations of Wi-Fi have sprung onto the scene at a rapid pace in recent years. After a storied five-year presence, Wi-Fi 5 was usurped in 2019 by Wi-Fi 6, only for the latter to be toppled a year later in 2020 by an intermediate generation, Wi-Fi 6E. And now, just a couple years later, we’re on the verge of Wi-Fi 7.

Wi-Fi 7 (the official IEEE standard is 802.11be) may only give Wi-Fi 6 a scant few years in the spotlight, but it’s not just an upgrade for the sake of an upgrade. Several new technologies—and some that debuted in Wi-Fi 6E but haven’t entirely yet come into their own—will allow Wi-Fi 7 routers and devices to make full use of an entirely new band of spectrum at 6 gigahertz. This spectrum—first tapped into with Wi-Fi 6E—adds a third wireless band alongside the more familiar 2.4-GHz and 5-GHz bands.
