Answer 2

According to the basic laws of physics, every machine needs an energy source for performance of the work.

And the energy generation part of the machine is sometimes integrated with the main machine body for a efficient machine work.

For example:

1) Cars : All the modern vehicles get their energy from their engines which are previously integrated in the body of the car.

2) Any kind of power cell (battery) operated equipments. Eg, Remote,Torch,Mobile etc.

3) Different types of Turbines.

And many more.
