It is the planemaker’s latest effort to draw public attention to its “zero-emission” ambitions as European governments push for cleaner technology in their post-COVID recovery plans.

Airbus AIR.PA has set itself a deadline of 2035 to put a carbon-free commercial aircraft into service, a target engine makers like Safran SAF.PA have described as ambitious.

The “ZEROe” initiative includes concepts for two conventional-looking aircraft: a turbofan jet engine able to carry 120-200 people over 2,000 nautical miles (3,700 km) and a turboprop able to carry up to 100 people for 1,000 nm.

Unlike normal planes, the engines would be adapted to burn liquid hydrogen stored in the rear fuselage.

A third proposal incorporates a revolutionary “blended wing body” design similar to one presented in February.

At the same time, Airbus is working on a demonstrator, with initial results expected in 2021.

“The demonstrator will allow us to assess what the most promising architecture is,” Airbus Chief Technology Officer Grazia Vittadini said in an interview.

“We see it as applicable to all Airbus products eventually.”

To meet its 2035 goal, Airbus would need to select technologies by 2025, she said. Other industry executives said such a clean break in propulsion could take until 2040.

Challenges include finding ways to safely store volatile liquid hydrogen during flight at very cold temperatures.

Airbus dismissed concerns that hydrogen would be unsafe and has called for massive investment in new energy infrastructure.

While hydrogen has been discussed since the 1970s, it remains too expensive for widespread use. Proponents say infrastructure investment and rising demand will lower the cost.

Most hydrogen used today is extracted from natural gas, which creates carbon emissions.

However, Airbus said the hydrogen used for aviation would be produced from renewable energy and extracted from water with electrolysis. That’s a carbon-free process is powered by renewable electricity, but it is currently more expensive.

Amazon has a new cure for long supermarket lines: a smart shopping cart.

The cart, which Amazon unveiled on Tuesday, uses cameras, sensors and a scale to automatically detect what shoppers drop in. It keeps a tally and then charges their Amazon account when they leave the store. No cashier is needed.

It’s the latest attempt by Amazon to shake up the supermarket industry and offer a solution to long checkout lines. The online shopping giant opened a cashier-less supermarket in Seattle that uses cameras and sensors in the ceiling to track what shoppers grab and charge them as they leave. Amazon.com Inc. also has roughly 25 cashier-less convenience stores with similar technology.

The cart, called Amazon Dash Cart, will first show up at a new Los Angeles supermarket Amazon is opening later this year. The store will have cashiers, but Amazon said it wanted to give shoppers a way to bypass any lines. In the future, it could be used at Amazon’s Whole Foods grocery chain or other stores, if Amazon sells the technology, but there are no plans for either right now.

Several startups are already making similar smart shopping carts that are being tested in stores, but many require scanning groceries before dropping them in.

There’s no scanning on the Amazon cart. A screen near the handle lists what’s being charged, and the cart can detect when something is taken out and have it removed from the bill. And there’s also a way to let the cart know if you need to throw a jacket or purse in the cart so you don’t have to carry it around.

At this point, nearly all of Google’s first-party apps have dark modes. There are some glaring exceptions to this, but fortunately version 2.27 of Google Home today adds a dark theme.

The Google Home dark theme is quite straightforward, with the stark white background turning into the same shade of dark gray used by every other Google app. It makes for a world of difference, given that you’re controlling your smart devices throughout the day and long into the night. It starts at the splash screen.

All icons, including the shortcut rows at the top of the app and device stand-ins, are appropriately adjusted and tinted. The text for room names are now white against the darker background, while devices are gray.

This dark theme spans every menu and screen in Google Home 2.27. This includes the Primary events feed, settings menus, panes, and more. There is no option in app preferences to independently set the dark theme independent of your device’s theme.
In addition to un/locking the Nest x Yale Lock, the Home view of all your devices will soon identify the on/off state of lights, switches, and plugs.

Google Home 2.27 with a dark theme for Android is rolling out now via the Play Store. Version 2.27 is available for iOS today, but the new look is coming via a server-side update.

Facebook will buy REI’s new and unused Bellevue campus for nearly $368 million, the social media giant said on Monday.

The move further consolidates Facebook’s domain in the upscale Spring District east of Interstate 405 in Bellevue, The Seattle Times reported. Before the acquisition of the 400,000-square-foot (37,161-square-meter) REI offices, Facebook was already moving to occupy nearly 850,000 square feet (78,968 square meters) in three Spring District buildings.

The company, which opened its first Puget Sound office in 2010 with three engineers, now employs more than 5,000 workers in dozens of locations in Seattle, Bellevue, and Redmond. That places it alongside Google as the area’s largest out-of-town tech employers. The Seattle area is home to Facebook’s second-largest office footprint, after its headquarters in Menlo Park, California.

“Our growth over the last decade is a testament to the thriving community and immense talent pool that has welcomed us with open arms,” said Nick Raby, Facebook’s director of North American real estate, in a statement. “This purchase doubles downs on our investment in Bellevue and our commitment to the Pacific Northwest.”

The deal signals there is “no single approach” for white-collar employers envisioning the future of office space as work-from-home regimes stretch into their seventh month, said Greg Johnson, the CEO of Spring District developer Wright Runstad & Company.

REI decided to sell its campus after the coronavirus pandemic hammered sales, leading the outdoor equipment retailer to conclude that it couldn’t afford not to sell the space. The company’s work-from-home program also proved to be surprisingly successful, said Ben Steele, REI’s chief customer officer. REI will rely more heavily on remote work and smaller satellite offices.
