Energy crisis and environment deterioration are two major problems for 21st century. Thermoelectric device is a promising solution for those two problems. Thermoelectric generator (TEG), is device that convert heat energy into electric energy. This generator accomplish this task by using arrays of specialised circuits known as thermoelectric modules, each of which consists of semiconductor materials -- known as p-type and n-type -- san […]

The design of the PIC microcontroller LED clock consists of few components that implement a solar powered digital street clock using LED display pattern. In this paper the LED clock was designed with 12 red LEDs in the outer circle, 12 green LEDs in the inner circle and four centralized yellow LEDs. The four yellow LEDs were used to count and indicate four minutes in consecutive pattern. The inner 12 green LEDs were used in indicating […]

This paper explores the utilization of a flywheel system for generating free energy. The flywheel's energy storage capacity is harnessed to produce additional free energy, which is subsequently used to power other electrical appliances. The system involves a half-horsepower AC motor driving a series of belt and pulley mechanisms that form a gear-train, resulting in a significant increase in RPM at the alternator shaft. A notable aspec […]

This work is on design and construction of a 500w solar generator. Portable Solar generator is a portable device that converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. In solar generator, Solar panels produce direct electricity with the help of electrons t […]
Years from now, with the estimated growth in world population and economic activities, fossil fuels which currently generate more than half of the world’s energy needs would not be able to keep up with this pace because it is a non-renewable source of energy, in other words exhaustible. Nigeria today is witnessing perhaps the worst power generation and distribution crisis in many years. To redress this situation, experts in the field o […]
