            \nThe steam engine changed many production processes in factories. Later on with a new source of energy such as electricity, factories that we see them today emerged. When a new machine or method of production is created for the first time, it is called an invention. However, practical application of these ideas takes a long time and depends on many factors. These could be improvements to make the technology effective, reducing cost of new techniques, acceptance of a new way or product. Technical developments or technical improvements can be due to completely new types of machinery (X ray machines and power looms), or changes in the types of raw materials used (plastic instead of rubber), or reorganisation of production processes.<\/p>\n
