Europe’s deepest mine to become giant gravity battery (www.independent.co.uk)

An abandoned mine in Finland is set to be transformed into a giant battery to store renewable energy during periods of excess production.

The Pyhäsalmi Mine, roughly 450 kilometres north of Helsinki, is Europe’s deepest zinc and copper mine and holds the potential to store up to 2 MW of energy within its 1,400-metre-deep shafts.

The disused mine will be fitted with a gravity battery, which uses excess energy from renewable sources like solar and wind in order to lift a heavy weight. During periods of low production, the weight is released and used to power a turbine as it drops.

I'd honestly prefer raw parroting in most cases, even if it's "obviously" wrong. I don't want people selectively interpreting the facts as have been conveyed to them, unless they're prepared to do a proper peer review.

That’s what [sic] is for though. You fact check, and then leave the quote as the press release had it.

The problem is that most of these articles are basically reprinting of the press release without any editorial additions at all.

I'd wager they let bots crawl articles and have said ai bots rewrite them slightly. Internet journalism is completely lost.
