Generating Electricity from Nitinol Shape Memory Alloy Wires

Clean, alternative energy resources have been the talk of research and development for the past decades. This project introduces a novel way of obtaining electrical energy through the implementation of Nitinol wires, a shape memory alloy (SMA) formed from Nickel and Titanium. A pulley system, over which Nitinol wire loops will be mounted, is designed and manufactured. The pulleys are immersed in mediums of different temperatures, to allow for the temperature gradient that the SMA wire needs for martensitic transformation. Heat energy from the hot water (medium) acts as an input to the system, in addition to an initial push that initiates system rotation. The system is linked to a shaft that is attached to a generator, which will harness and transform the system’s mechanical energy into electrical energy. This report provides a comprehensive technological and literature review on the relevant topics of SMAs and electricity generation.

This project aims to investigate whether UAE’s desert sand can be utilized as a medium to store thermal energy in concentrated solar power applications. Sand can provide a unique and eco-friendly alternative, while having minimalized cost and maintenance. Oil will be heated and pumped to flow through pipes leading to the thermal energy storage element, where the sand will be thermally charged. After the desired temperature in the sand is obtained, a certain storing period will follow. Finally, the remaining heat will be discharged and absorbed by the oil, whose heat will be utilized to generate electricity using a thermoelectric generator. For the completion of this project a functioning prototype is to be expected along with mathematical modelling, design considerations, as well as thermal and flow simulations. Through these, the storage system’s cost efficiency will be determined for its use in concentrated solar power applications.

The purpose of this project is to create a model of an electricity generating tile. As the name states, the focus is to generate green electricity using a free source of energy; in our case being footsteps. Our project aims to aid in making the world a sustainable place. This is done by creating a tile system consisting of two systems. The first system is a purely electrical system; its main components are piezoelectric elements that convert mechanical stresses into electricity. The second system is a mechanical system that’s main components are a rack & a pinion. As the tile displaces, the rack’s linear displacement will drive the pinion to rotate. This system also consists of other components such as a gearbox, two freewheels, a gearbox, and a flywheel. The output of the flywheel is connected to a generator that converts rotation into electricity.

The impact of solar panels – a source of renewable energy – in generating power, has increasingly become an area of interest, especially with the rise of sustainable development. One method is developing active solar tracking panels that are always perpendicular with sunrays, and have in implemented power management strategies to reduce the system’s power consumption. Group#4 will be designing a system that is aiming to achieve this goal. The final prototype will have servomotors and light dependent resistors circuits installed on it, in order to achieve the tilting and rotation of the panel. A theoretical analysis is developed by presenting a conceptual design, a mathematical model, differential equations. The standard components are selected, and the full system was modeled using a SolidWORKS. Theoretical work is supported by simulated motion studied of the system to insure validity of calculations, and the functionality of the system.
