Hi guys Let me introduce you a very special topic i.e. From steam engine to dream engine. The technological and continuous transformation has opened various ways with boundless possibilities. Industrial revolution sparked by steam engine has taken steps towards digital revolution driven by artificial intelligence. So let's learn about the journey travelled by engine which helped us to enhance our daily lives and make the world a single family by means of globalisation. It is the symbol of the progress of development and innovation for humanity. The birth of steam engine The steam engine invented in late 17th century . Before it's innovation human labour and animal power was the primary source of energy. Firstly it was developed by Thomas newcomens in the early 17th century which is used to pump water out of mines. After that in the 1760s it is the James Watt who makes a improvement in it and add seperate condenser and rotary motion due to which use of the engine enh...
