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.
The by-products of burning coal. I have written about the copious amounts of carbon dioxide that coal fired power stations push into the air â far greater amounts per unit of electrical energy than any other form of electrical generation. However, the coal pollution is not limited to carbon dioxide, which warms up our planet. There are other dangerous by products of coal burning. Of course the actual types of by product depend on the nature and quality of the coal that is burnt, and its energy content.
