That version of the story goes something like this: On July 1, 1937, Amelia Earhart and her navigator Fred Noonan departed from Lae, New Guinea in Earhartâs Lockheed Electra 10, on what was to be the longest portion of Earhartâs highly publicized round-the-world flight.
The youngest coal is not even coal yet -- peat. Peat is a traditional fuel in parts of the world, like Ireland, where it is cut from the earth, dried, and burned for heat. The energy content of peat is quite low. Young coal is called lignite, and is soft and brown, not much different than dried peat.
Coal is also used in manufacturing. If coal is heated the gases, tars and residues produced can be used in a number of manufacturing processes. Plastics, roofing, linoleum, synthetic rubber, insecticides, paint products, medicines, solvents and synthetic fibers all include some coal-derived compounds.
