The majority of humanity's electricity comes from heat – burning coal or natural gas, nuclear fission, concentrating solar – that's used to boil water and spin steam turbines. This method of power generation has been around since Charles Parsons first hooked a steam turbine up to a dynamo in 1884, and licensed the patent to George Westinghouse. Over the last century and a half, it's become ubiquitous all over the world as a mature and well-optimized technology with known strengths and limitations. One of those limitations…
