When in 1939 war did break out between Germany on the one hand, and Britain and France on the other, President Franklin D. Roosevelt dutifully invoked the Neutrality Acts. However, he believed that this was a fundamentally different war from World War I.
Another advanced coal technology is coal gasification, a process in which coal is converted to a gas (called syngas) before it is burned, making it easier to separate CO2 as a relatively pure gas before power is generated.
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.oal is also used as a power source for factories. There it is used to heat steam and the steam is used to drive mechanical devices. A few decades ago most coal was used for space heating. Some coal is still used that way but other fuels and coal-produced electricity are now used instead.
