i think this....
The first steam powered devices were pumps. The first practical one being developed by Thomas Newcomen. This steam powered pump was used to not only pump water from mines but also to blow air into furnaces, and for pumping drinking water into towns.
James Watt's development of the steam engine led to a large number of further developments. using steam to create energy meant that this new form of powering a machine could be used anywhere, rather than just next to a stream/ river as with the Water Frame. The steam engine is best associated with the invention of trains but also was used to power machinery in factories, to power lifts in mines and for many other purposes.
The industrial revolution gave birth to Hydraulic Power. Gas struts, cable laying equipment, marine winches and hydraulic winches are just some things that rely on hydraulic power today. Hydraulic Cylinders also rely on hydraulic power.
so as per my explanation, i will go for steam engine....
