Rotational Energy Harnessing from a Non-Fixed Axis System(REHNFA) is a device consisting of a Yo-Yo mechanism. In this mechanism, a rotor is punched two holes and two strings of elastic material are passed through in it. By applying little starting rotation to the rotor by oscillating the strings it continues its rotation for a long span and that rotation can be harnessed to energy generation/utilization. This study has been undertaken to investigate the research papers of Yo-Yo De-spin Mechanism which is mostly used to reduce the spin of satellites, typically soon after launch. The de-spin mechanism is similar to the Yo-Yo mechanism with a difference in the positions of rotor, weights and axis.
