The Download: good climate news, and promising pixels

New technologies that can help address climate change, from heat pumps to solar panels to EVs, are coming to the market and getting cheaper. Climate policy is also developing, from incentives to support new technology to rule-making around pollution. 

And efforts to help the most vulnerable nations adapt to climate change are growing. Read on for a few of those bright spots that our climate reporters saw in 2023.

These minuscule pixels are poised to take augmented reality by storm

Google Glass, a prototype augmented-reality headset released in April 2013, had the makings of a hit. But Glass was awkward to wear and struggled to deliver a sharp, bright image outdoors. Then came the “glasshole” backlash.

The implications were clear. Hands-free augmented reality (AR) was fun on paper, but with tensions over Big Tech’s influence mounting, it couldn’t overcome the stigma of making people look like extras in a cyberpunk flick.  

Now, more than a decade later, the future Google envisioned—and much more—is on the brink of becoming reality. Tiny new displays, some small enough to fit on the tip of your finger, will contain micro-LEDs and micro-OLEDs—and they’re set to deliver a wave of headsets that may convert even the most ardent AR skeptics.

China’s judicial system is becoming even more secretive

Last week, a leaked document started circulating online from China’s highest court saying that by the end of 2023, courts of all levels should finish uploading their judgments to a new “National Court Judgment Document Database.” This database will come online in January and will only be accessible to internal staff. 

Building an internal digitized system isn’t inherently bad. But the news caused alarm because academics and other experts believe it is likely to replace a similar resource that was free and open to the public: China Judgements Online. 

CJO is one of the largest widely accessible databases. By allowing the Chinese public to search through millions of detailed court judgments, it was able to hold the powerful accountable, at least to some degree. If it goes away, that will have a big impact both on Chinese people and those observing from the outside. Read the full story.

The big story

These exclusive satellite images show that Saudi Arabia’s sci-fi megacity is well underway

December 2022

In early 2021, Crown Prince Mohammed bin Salman of Saudi Arabia announced The Line: a “civilizational revolution” that would house up to 9 million people in a zero-carbon megacity, 170 kilometers long and half a kilometer high but just 200 meters wide. Within its mirrored, car-free walls, residents would be whisked around in underground trains and electric air taxis.

Satellite images of the $500 billion project obtained exclusively by MIT Technology Review show that the Line’s vast linear building site is already taking shape. Visit The Line’s location on Google Maps and Google Earth, however, and you will see little more than bare rock and sand.

The strange gap in imagery raises questions about who gets to access high-res satellite technology. And if the largest urban construction site on the planet doesn’t appear on Google Maps, what else can’t we see? Read the full story.
