CleanSpark (NASDAQ:CLSK) acquires 20 MW immersion cooling infrastructure for its Norcross bitcoin mining facility, the company says. Liquid immersion cooling is where the mining machines are fully immersed in a specialized cooling liquid to increase the hashrate of bitcoin mining machines. Phased installations start immediately, with the first eight MW expected to go live in February. Still, shares of CLSK fall 5% as Bitcoin (BTC-USD -3.1%) slumps. The immersion cooling technology is anticipated to increase bitcoin mining efficiency by 20% or more, according to industry standards and the manufacturer; it will also reduce operating expenses. Upon completion, the 20 MW project will consist of 180 liquid-filled tanks, with each tank holding 33 units of the Antminer S19j Pro machines. Previously, (Dec. 6) CleanSpark produced 218 bitcoins in November.
