Abstract: The present invention relates to a power-generating apparatus using a difference in gravity. In detail, a weight which moves in the upward and downward directions is arranged in a watertight manner in a driving body such that a liquid is introduced from a liquid inlet pipe to increase the weight of the driving body when the weight moves in the downward direction and blocks an opening. When a plurality of thus-configured driving bodies move in the downward direction and then move in the upward direction, liquid inlet ports of the driving bodies are blocked by the respective weights, and the liquid in each empty chamber of the driving bodies is pushed into a lake by the weights to decrease the weight of the driving body, thus generating power from a difference in gravity. The energy supply and demand problem has been regarded as a significant issue as industrial society develops. Therefore, global concerns about the development of natural energy are increasing, and a wide variety of power-generating apparatuses using gravity and buoyancy have been developed under such circumstances. However, actual circumstances are that such power-generating apparatuses may not be put into practical use as they are disadvantageous in terms of cost of equipment and operating expense. The present invention is achieved to solve the above-described problems, and the technical features of the present invention relate to a power-generating apparatus in which a chain is connected between a driving chain gear installed in an upper driving body group and a no-load chain gear installed in a lower driving body group, the plurality of driving bodies are connected to the chain at regular intervals, a circulation hose is arranged outside the driving bodies, and liquid inlet pipes are connected to the respective liquid inlet ports formed in upper portions of the driving bodies such that the weight arranged in the top driving body moves in the downward direction to block the opening formed at the bottom of the top driving body to form an empty chamber. Here, a liquid is introduced to the closed empty chamber of the top driving body through the liquid inlet port connected to the circulation hose to generate gravity which serves as rotating force. In addition, when the liquid is introduced into the top driving body, the top driving body moves gradually in the downward direction by means of the weight of the liquid such that power is generated from the total weight of the liquid in each driving body. When the bottom driving body rotates in the reverse direction and moves in the upward direction, the weight in the bottom driving body moves to block the liquid inlet port and the liquid is prevented from being supplied into the circulation hose. When the driving body which has been raised to the top moves in the downward direction when no liquid is being supplied to the circulation hose, the weight moves to block the opening of the empty chamber to make the empty chamber watertight, and the liquid is introduced through the liquid inlet port of the watertight empty chamber, thus generating power. The power-generating apparatus of the present invention generates power by repeating the above-described operation, and when the liquid is consumed during operation, high-pressure liquid is discharged, by means of the operation of a sensor valve, from an auxiliary liquid bag connected to the liquid inlet pipes, to automatically replenish the consumed liquid.
