“Our goal is to find out how much sediment the harvester will take off along with the nodules,” says Matthias Haeckel, a marine biochemist at the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, who is coordinating the environmental review of GSR’s activities for a project called MiningImpact.
Although the team is not the first to develop a cobalt-free or high-nickel cathode, Manthiram says it’s the first one that doesn’t also have major performance drawbacks like short battery life and low energy density.
The abundant water and underground heat is harnessed by hydroelectric dams and geothermal power stations to produce cheap, green electricity that facilitates the energy-intensive process of confirming cryptocurrency transactions—called mining, since miners are rewarded for their efforts with newly minted and extremely volatile “coins.” The fact temperatures rarely top 57 degrees Fahrenheit also helps.
Lignite mining has already swallowed nearly half a million acres of Germany's land—including hundreds of villages, roads, and forests.Photograph: Tom HegenHegen's photos depict the Lusatia mining district in eastern Germany, from which roughly a third of the country's lignite hails.

Bitmain, a Chinese company that makes specialized computers for “mining” cryptocurrency, said it would invest $500 million in what was to be the world’s largest bitcoin -mining facility at the closed Alcoa smelter, which, crucially, was still connected to massive electrical lines.
In a paper published Wednesday in the journal Joule, his team takes a closer look at the energy consumption of bitcoin mining, based on where miners are located and the types of machines they are using.
Radiohead Gets ‘Hacked,’ a T-Mobile/Sprint Hiccup, and More News. Radiohead owned some hackers, the T-Mobile/Sprint merger runs into some hiccups, and a Swedish mining town is being picked up and moved. So their state-owned mining operation decided to move the city instead.
To address this deforestation, a forest-smart approach to mining requires strong governance to manage the development and impacts of the mining sector, protect forests on a landscape level, and recognize and protect local community tenure and rights.
An executive who works closely with Chinese mining firms told WIRED that although the ban was widely expected to move forward, miners expect it will take years for the government to fully rein in their operations.
A spokesperson for Linzhi, in an email to WIRED, called it a move to “counter Chinese supremacy in crypto.” But many critiques have centered on Minehan herself, focusing on her experience working with GPU makers and alleging that she had been paid to develop the algorithm.
It comes in advance of a resolution that would commit the Missoula area to 100 percent clean electricity by 2030.“We looked at the potential for new bitcoin mining and saw that we’re never going to meet these goals if mining happens in the way it’s been happening,” says Josh Slotnick, who sits on the board of commissioners.
The Exaggerated Promise of So-Called Unbiased Data Mining Getty Images Nobel laureate Richard Feynman once asked his Caltech students to calculate the probability that, if he walked outside the classroom, the first car in the parking lot would have a specific license plate, say 6ZNA74.
For example, the cloud monitoring and defense firm RedLock said in February that Tesla's Amazon Web Services cloud infrastructure was running mining malware thanks to an inconspicuous, but extensive cryptojacking campaign.
This may reflect the declining contribution of agriculture, in which the majority of poor households are engaged, the limited job opportunities for higher productivity in the services sector, and a largely capital-intensive industrial development.
If Germany Can't Quit Coal, Can Anyone Else?Germany's switch from black to brown (lignite) coal is making it tougher to meet carbon reduction goals.Dusan Bartolovic/Getty ImagesSometime next month, underground miners will dig Germany’s last ton of black coal, load it onto a conveyor belt, and whisk it a mile to the surface of the Ibbenbüren mining facility.
