Dead EV Batteries Are Hoarding a Shocking Amount of Useful Lithium

The lithium batteries we deem unfit for use in electric vehicles might still contain copious amounts of usable, pure lithium we could retrieve and reuse—a potentially consistent, bountiful supply we’re just not trying hard enough to tap into, a new study suggests. In a study published August 14 in the Journal of Environmental Management, researchers at Edith Cowan University (ECU) in Australia argue that tapping into the leftover lithium in used batteries could fuel a pragmatic, sustainable alt

Charter Planes and Bidding Wars: How Bitcoin Miners Raced to Beat Trump’s Tariffs

Twelve minutes after midnight on April 8, a Boeing 777-300ER barreled down a runway at Singapore Changi Airport. In its belly, it carried precious cargo: 3,000 kilograms of specialized bitcoin mining equipment bound urgently for New York. As the plane took to the sky, staff at US-based Luxor Technology could begin to relax. The company, which trades bitcoin mining hardware and provides related software services, was importing the equipment on behalf of a client. The flight’s departure from Sing

Planned EV Battery Plant Is a ‘Death Sentence’ for Uncontacted Indonesian Tribe

On Sunday, June 29, Indonesia will break ground on a $6 billion electric vehicle (EV) battery plant on Halmahera, the largest of the Maluku islands. The facility will mine the island’s abundant nickel reserves and manufacture batteries on-site to reduce production costs in Indonesia, but a watchdog warns it could decimate an uncontacted tribe. The Hongana Manyawa—whose name means “people of the forest” in their language—are one of the last nomadic hunter-gatherer peoples in Indonesia, according

Breakthrough non-toxic method developed to extract gold from e-waste

Forward-looking: A team of Australian researchers has unveiled a breakthrough method for extracting gold that could dramatically reduce the environmental and health hazards long associated with mining and electronic waste recycling. The innovation, developed at Flinders University, offers a safer and more sustainable alternative to the use of toxic chemicals like mercury and cyanide, which have historically dominated the gold recovery industry. Gold, prized for its rarity and versatility, is es

Core Scientific shares surge 33% on report of buyout talks with CoreWeave

Core Scientific shares surged 35% on Thursday following a report from The Wall Street Journal that artificial intelligence infrastructure vendor CoreWeave is in talks to acquire the bitcoin mining and hosting provider. The company's stock was briefly halted after the report, and then proceeded to have its second-sharpest rally since Core Scientific returned to the Nasdaq in January 2024 after completing a reorganization. Its biggest one-day gain came last June, when the shares popped 40% on new

A False Start on the Road to an All-American Bitcoin

US president Donald Trump waited a beat to soak up the applause. In front of a baying crowd of bitcoiners at crypto conference Bitcoin 2024 in July, he had just laid out his plan to turn the US into the world’s undisputed bitcoin mining superpower. “I want it to be mined, minted, and made in the USA,” he told the audience. “You’re going to be very happy with me—you’re going to be so happy.” Since returning to the White House, Trump has largely followed through on his crypto-related pledges: He
