Direct Current (DC) Supergrids are appearing in China, India. Europe and Brazil. Long-distance ultra-high-voltage direct-current (UHVDC) connectors are now transmitting electricity over thousands of kilometres more efficiently than AC or alternating current. China began building these transmission facilities in 2010 and is currently has one under construction that will carry 12 gigawatts (half the average power use of Spain) over 3,400 […]

MIT Technology Review has an article about robots mining 24 hours a day. Mining companies are rolling out autonomous trucks, drills, and trains, which will boost efficiency but also reduce the need for human employees. Mining companies are well placed to expand automation rapidly, because they have already invested in centralized control systems that use software […]
