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 […]

Scientists from the UK’s University of Bristol have developed a lab-made nuclear diamond that can generate electricity and is made from radioactive waste. The diamond battery has an incredible lifetime, and will only be half used up by the year 7746.  As most people know, a severe downside of the nuclear fission process is the creation of dangerous radioactive waste, which […]
