Utilization of coal as an energy source

Coal replaced wood as the principal source of energy in the United States by the 1890s. The first coal-fired power plant was built in 1882, generating steam that turned a generator to make electricity. In 1884, Charles Parsons developed the more efficient high-speed steam turbine. By the 1920s, pulverized coal increased efficiency and reduced the air need for combustion.

The 1940 cyclone furnace used poorer-grade coals to produce less ash. Recently chemical technology has developed the combustion of culm (waste material from coal mining) to produce power and to decrease environmental load.

Scientists are working hard on synthetising diamond. According to their hypothesis, the super diamond would have all the characteristics of the natural diamond; however, it could be produced in all shapes and sizes.
