Data centres are not the most glamorous topic of discussion but they are everywhere, powering our modern, digital economy. But they can also power swimming pools, breweries and laundries, as Mark Bjornsgaard tells Hannah and Rob on this episode. 97% of the electricity that goes into a computer comes out as heat. It’s an incredibly inefficient process, and more often than not this heat isn’t used. So, rather than building these data centres in the middle of nowhere, Mark’s company Deep Green is taking computing power to where heat is needed, offering a precious resource to communities across the UK. Could this be scaled up for use across the world?
