[quote]THE NEXT BIG BOOST FOR BITCOIN MINING: OIL IMMERSION COOLING
Bitcoin mining, by design, is increasing in difficulty. Enthusiasts mining in their basements have given way to professionally managed cloud services that deploy equipment on a massive scale. Growing energy requirements and build costs are catching up with the rapidly increasing global hashrate, putting downward pressure on available margin. As mining gets more competitive, GRC’s oil immersion cooling technology promises to boost profitability by reducing build-out and operating costs dramatically.
Oil immersion cooling from Green Revolution Cooling differs from every other form of precision and/or liquid cooling. It is designed to provide easy-to-scale, industrial cooling for high densities with a bare minimum of initial infrastructure and ongoing power requirements.[/quote]
