Turbine Design

A micro-fluid turbine with mechanical energy storage system is designed and successfully tested in laboratory. As energy supplement for deep ocean installations, this patent design solved the problem of difficult generating electricity in ultra-low speed flow. The conventional marine current turbine can hardly get start in flows with velocity lower than 0.5m/s, whereas the marine current speed is seldom higher than one knot in deep sea. By adding a mechanical energy storage system, the rotor of the micro-fluid turbine first captures the fluid kinetic energy from the ultra-low speed flow, and then the energy transferred to the mechanical energy storage system, in which a plane scroll spring is used to store the limited energy and drive the generator automatically when it has enough potential energy. Simulation and laboratory test show that this method has potential for power generating in low density ocean current environment.

Locomotory Performance

Elastic energy storage mechanisms have been shown to improve locomotory performance and efficiency in many animals. In this paper we consider the role of elastic energy storage in jet locomotion of the squid, Loligo opalescens. The jet is powered by the contraction of circular muscles in the mantle. In addition, the mantle contains a collagen fibre based energy storage system (the mantle "spring") which captures some of the mechanical energy produced by the circular muscles and then releases this energy to power the refilling of the mantle cavity. The mantle spring is constructed so that it stores energy from the circular muscles only at a time in the jet cycle when, by virtue of the cylindrical geometry of the mantle, the circular muscles are unable, to apply their full mechanical output to the generation of hydrodynamic thrust. Thus the mantle spring increases the utilization of the circular muscles, and our analysis indicates that these muscles are used at virtually 100% of their potential through the entire jet. Presumably this increase in muscle utilization improves the locomotory performance of the squid. Other swimming animals, such as fish, may obtain similar benefits if elastic energy storage systems are constructed to capture energy at a time in the swimming cycle when muscles can not apply their full output to the generation of useful hydrodynamic forces.

Capturing braking energy by regeneration into an onboard energy storage unit offers the potential to reduce significantly the fuel consumption of vehicles. A common technique is to generate electricity in the motors of a hybrid electric vehicle when braking, and to use this to charge an onboard electrochemical battery. However, such batteries are costly, bulky, and generally not amenable to fast charging as this affects battery life and capacity. In order to overcome these problems, a mechanical energy storage system capable of accepting and delivering surges of power is proposed and investigated. A scale physical model of the system, based around a flywheel, a planetary gear set, and a brake, was built and operated in a laboratory. Tests showed that the proposed system could be used to store and provide braking energy between a flywheel and a vehicle, the latter emulated by an air-drag dynamometer. This validated the operating principle of the system and its computational model. Further, a computational analysis of a full-size vehicle incorporating the mechanical energy storage system was conducted. The results showed that the utilization of this system in a vehicle, when compared with a conventional vehicle, led to reductions in emissions and fuel consumption.

Tidal Power

Recent days, more and more people are becoming interested in "free-energy". "Free-energy" means the energy sources used freely without to pay. The sources of "free-energy" are sunlight, rainfall, wind energy, wave power, and tidal power. There are other sources of power such as gravity, electrical charge in the atmosphere and ionosphere, and a mass. FESS (Flywheel Energy Storage System) is an attempt to store kinetic energy generated from the rotation flywheel in which the electrical power output from the generator as an input to the motor. Mass flywheel greatly affects the amount of power generated by a generator which will serve as a flywheel device or distributors of energy while at the induction generator to eventually convert mechanical energy into electrical energy and vice versa. In this system design becomes very important for the flywheel can store the kinetic energy. This research aims to design and build mechanisms as a means of comparison FESS flywheel effect of the geometry of the kinetic energy generated. The research method is done by making three different geometric design flywheels, and then analyzed with the help of FESS. From the experimental results, flywheel 1 with a ringtype web-concave generate kinetic energy of 312.30 J and specific energy of 31.23 J / kg, at the flywheel 2 which is type-straight arm kinetic energy gained by 316.73 J and energy specific of 31.67 J / kg and flywheel 3 with a ring-type web-straight kinetic energy obtained by 284.997 J and specific energy of 28.49 J / kg. From the research data we can conclude that each design geometry flywheel has a different contribution to the performance of energy storage.
