Energy Efficiency Feasibility Study of a Novel Buoyancy Driven Hydropower Generation Machine

A. Shokohi and A. Kiyoumarsioskouei
Abstract—Utilization of the different mechanism to earn river’s hydropower had been a long-term target for human beings. One of the new methods for achieving this end is reciprocating buoyancy driven mechanism which contains three Vertical cylinders with a light piston in the central cylinder. Fluid is being led to downstream of the system from one of the cylinders by opening the discharge valve of the aforementioned cylinder; water pressure exerts force on the piston which is located in the other parallel cylinder and consequently the piston moves, this would basically be the power generation cycle. In the next step discharge valve of the second cylinder is opened and leads the water to the drainage. This step simply facilitates the piston's return to the initial position. Calculating the head loss occurring inside the cylinders and the other losses results the efficiency estimation more than 90 percent that could be improved easily by optimizing the design and also using better quality materials in the manufacturing process of the machine. This could be an appropriate achievement for regenerative energy production enhancement in the world.

Index Terms—Clean energy, hydropower, reciprocating mechanism, head loss.
