    The Impetuses and Hurdles of Renewable Energy Applications and Development in Montserrat
    (2019-11-11) UZORKA, AFAM; MAKERI, YAKUBU AJIJI; ODEBIYI, SAMUEL OLUWASEGUN
    The economy of Montserrat was severely disrupted by volcanic activity which began in July 1995. Prior to this date, Montserrat is an open and dependent micro-economy with limited economic activity which is the biggest threat to sustainable energy development. Above all, Montserrat dependency on the fossil fuel is the biggest obstacle for the long term economic growth. The combination of these challenges gives impetus for Montserrat to diversify its economy via a green economy that will pave a way for the long term economic stability while addressing environmental and social concerns in the country. Montserrat has adapted long-term plans for a transition to green economy. A major strategy is to replace fossil fuels with renewable energy (RE) sources as the fundamental energy source. Montserrat has substantial RE resources for the provision of energy services and production, yet these resources remain untapped. It is therefore crucial that the use of these abundant resources should be heightened. This paper examines and discusses the potential and current RE utilization and development in Montserrat from the perspective of sustainable development. The status of the different RE resources and their application/utilization, including details of existing projects in the country, are carefully explored and discussed. The possible impetuses for a huge advancement of RE applications and development in Montserrat are also discussed before explaining the major hurdles and challenges faced by the energy sector as regards RE. Measures and policies required to facilitate the utilization of RE in Montserrat are proposed. These evidence-based policies could guide the delivery of affordable and sustainable energy solutions for all by 2030 in Montserrat

    Design and Implementation of an Electrostatic Precipitator and Its Cleaning System for Small Scale Combustion
    (IIJSR, 2017-12) Adabara, Ibrahim; Hassan, Abdurrahman S; Hassan, Abdurrashid S
    A simple wire-plate electrostatic precipitator (ESP) was constructed in order to test the efficiency of collecting smoke particles from combustion of rubber-wood that is used as a source of biomass energy. The ESP contains collection cylinder electrode and 2 wire electrodes between cylinder. The maximum input voltage of the Wheatstone bridge circuit using a high-voltage neon transformer was 10.5 kV (DC). The gap between the cylinder and the distance between wires were adjustable. Results from the field test in a furnace indicate that the device could be used for a period of about one hour before cleaning the electrodes was required. The collection efficiency was decreased during the course of wood burning as the dust loading increased. Maximum efficiency was near 80% during the initial period. The distance between the collection plate electrodes had a greater influence on efficiency than the distance between the wire electrodes. The cleaning system used in this experiment was made from a row of PVC pipes to allow water to discharge radially to the cylinder electrodes on both sides. Efficiency was increased after 120. This ESP is suitable for small and medium-sized enterprises (SMEs) to alleviate the release of detrimental chemicals such as PAHs into the atmosphere.

    Design and Construction of RFID Wireless Car Security System
    (IJSES, 2017) Hassan, Abdurrahman S; Saleh, Mubarak Auwwal
    This project implements the function of wireless car security system using RFID. An ATMEGA8 microcontroller, RFID reader, RFID tag is used for the smooth implementation of the scheme. The ATMEGA8 microcontroller was used to serve as the entire control of the system which holds the unique RFID card number and controls the system as a whole. A driver is used to secures the car ignition system, and the buzzer was used to alert the vehicle owner whenever there is an intrusion attempt. Consequently, with this kind of system, the security of our automobiles can be more sensitive to secure and protect our vehicles more from any intrusion and theft in electronic-based approach.
