  Abstract
  
  Electricity is a vital part of modern society. We plug our electronic devices
  into wall sockets and expect them to get power. Power generation is a subject
  that is in the news regularly. The issue of the depletion of natural resources
  and the risks of nuclear power plants are often discussed, and developments in
  wind and solar power generation, as well as other renewables, are hot topics.
  Much less discussed is the transmission and dis
