The immersion-cooled Bitcoin mining rig cost about $120,000 to make and looks like something straight out of 'Stargate.'

At the core of most cryptocurrency networks are miners, the people who use specialized computer equipment to secure the cryptocurrency's blockchain by performing mathematical equations millions of times per second. In exchange for this computing power, and the electricity it takes to run the computer, these miners are rewarded in cryptocurrency proportionate to their contribution to the network. Given the high cost of electricity in many places and the computing equipment it takes to mine, it makes sense that miners try to maximize their return in any way possible.

This has resulted in some creative approaches to cryptocurrency mining—including running a mining rig in the back of a Tesla, setting up a wind-powered rig in a field, using your own breath to run a mining rig, and even a mining rig that harvests human body heat—but the immersion cooled rig from Reddit user 'Limping-Zebra' takes the cake, at least as far as cool factor goes.
