A steam engine is a device that converts the potential energy that exists as pressure in steam, and converts that to mechanical force. The industrial revolution came about primarily because of the steam engine. the first practical steam engine was patented by James Watt a Scottish inventor, in 1769. Steam engines are of various types but most are reciprocal piston or turbine devices.
Patenting of Dynamite
In 1867, Nobel received U.S. patent number 78,317 for his dynamite. To be able to detonate the dynamite rods, Nobel also improved his detonator (blasting cap) so that it could be ignited by lighting a fuse. In 1875, Nobel invented blasting gelatine in Paris and patented it in 1876. In 1887, he was granted a French patent for blasting powder "ballistite".
