You mean low-voltage DC distribution within a datacenter? That's useful but it's a different issue: the object here is long-distance (~1,000 km), high-voltage (~500,000 V) transmission. Economist didn't make this clear enough. http://www.abb.com/cawp/seitp202/65df338284e41b3dc1257aae0045b7de.aspx http://www.abb.com/cawp/seitp202/65df338284e41b3dc1257aae004... https://en.wikipedia.org/wiki/High-voltage_direct_current https://en.wikipedia.org/wiki/High-voltage_direct_current
