In what order did the widespread use of these technology come? Steel Electricity Refining A kudo to the person that can guess why I want this info. The clue is it has to do with entertainment. |

This is a complicated question. No easy answer there. Steel has been around for a very long time. At least since the 1700. I think the Bessemer proscess was invented in the early 1800 in England, but the Japanese had steel for their swords and the like centuries before. The Bessemer proscess only made steel production faster and cheaper than it previously was. Electricity came in stages. As of 1900 there were places in the US that had still not been hooked up to the grid. The same in England as of WW2. Before that there was electricity to an extent, as that ran the telegraph lines and such after (before?) the Civil War. Refining to an extent was around in the late 1800's. They made use of kerosene and, I think, Desiel. They dumped the gasoline into streams and rivers and such as a waste/byproduct of the refining proscess until someone figured out how to make a motor run on it. Hope some of this helps, and I reserve the right to be completely wrong on as much of this is incorrect. |

Refining? As in oil refining/catalysing/cracking or material refining? Refining is quite generic, removing unwanted materials from ores or oils has been going on for thousands of years. Copper and olive oil come to mind. Electricity has been used to electroplate gold for possibly thousands of years. Steel, I think is only a few hundred years. |
