It is the most commonly found invention. Without it there would have been no vehicle running on road.

Wheel was invented in the late Neolithic and was seen in conjunction with other technological advances that gave rise to the early Bronze Age(3300–2200 BC). This means that were no wheels even after the invention of agriculture and of pottery, during the Aceramic Neolithic.

In Middle Bronze Age(2200–1550 BC), the spoked wheel and the chariot wheel were invented.

2. Steam engine

A steam engine is a heat engine that performs mechanical work using steam generated from solar power, nuclear power or geothermal energy . The ideal thermodynamic cycle used to analyze this process is called the Rankine cycleSteam engines are external combustion engines.

James Watt
