Abstract: Closed system inertial devices are the devices that can produce a one directional force that would propel any given mass relative to it and hence forth would not follow the fundamental laws of Physics. It does not produce equal and opposite reaction as it uses specific arrangement of weights that can move within the device hence forth capable of moving the body without giving an equal and opposite reaction to move the body. The best way of proving such a device is to conduct an experiment in space or in mid-air so as to have least frictional resistance and no physical contact to other solid particles as of such.
