Technology news

Diversity can prevent failures in large power grids

The recent power outages in Texas brought attention to its power grid being separated from the rest of the country. While it is not immediately clear whether integration with other parts of the national grid would have completely eliminated the need for rolling outages, the state's inability to import significant amounts of electricity was decisive in the blackout.

Dangling tax credits and rebates in his drive to fight climate change, President Joe Biden wants you to trade your gas-burning car, truck or SUV for a zero-emissions electric vehicle.

The road not taken: South Korea's self-driving professor

Decades before the race to build a self-driving car became a multi-billion-dollar contest between tech giants such as Tesla and Google, a South Korean professor built an autonomous vehicle and test-drove it across the country—only for his research to be consigned to the scrapheap.

Scientists studying solar try solving a dusty problem

The layer of dust and pollen that settles on the windshield of your car is easily removed with a turn of the lever that activates wipers and water. Removing that layer from a solar panel—especially one inconveniently located from any source of moisture—requires considerably more work.

NFTs: Why digital art has such a massive carbon footprint

How much would you be willing to pay for a one-of-a-kind work of art? For some collectors, the limit lies somewhere in the region of hundreds of millions of dollars.

Welcome to the strange world of crypto art collectibles, also known as NFTs.

Britain's betting on buses: How far will boosting services reduce carbon emissions?

A move to "make buses the transport of choice, reducing the number of car journeys and improving quality of life for millions" has been launched as part of a national bus strategy in the UK. It seeks to make bus services more reliable and affordable to get people out of the cars that still dominate transport in the country.

Google's AI advertising revolution: More privacy, but problems remain

In March 2021, Google announced that it was ending support for third-party cookies, and moving to "a more privacy first web."
