Abstract

People are encouraged to install solar PV as the power supply to power the household by implementing a programme called NEM by the SEDA that allows users to consume the energy generated first and the excess energy will be transferred to the grid. The excess energy price will be cut in the next monthly electricity bill. This programme helps to reduce the dependency on fossil fuels and to improve the environment. This research focuses on the creation and design of an alternative energy such as bicycle generator by using a dynamo that can generate power to supply low-powered appliances. This project aims to find a low- cost alternative energy source by converting mechanical energy to electrical energy. Therefore, the perfomances of the bicycle generator needs to be analysed. It is important to have alternative energy resources because there are times when renewable energy is unable to produce optimum power due to intermittency. For example, solar PV will not generate any power during the night-time or rainy season. Therefore it is vital to have an alternative energy to overcome that situation instead of depending on fossil fuels. Fossil fuels is one of the major causes of the greenhouse effect and climate change due to the emission of carbon gas which causes the thinning of the ozone layer in the atmosphere. By using alternative energy resources, the emission of carbon gas can be reduced. Therefore, to achieve this, an alternative energy such as a bicycle generator is studied. It was found that it could generate a high power depending on the generator used and the speed of rotation of the bicycle wheel. The more the rotation of the wheel, the higher the voltage and current generated and thus, producing higher power. This can be achieved using a dynamo to convert the mechanical energy from the rotation of the wheel to electrical energy that produces an AC current. The current is converted into DC using a rectifier to power the claw machine that uses DC supply. To ensure a continuous flow of energy, a lead acid battery is used to store energy. In conclusion, it is possible to generate energy using a bicycle and dynamo to power low- powered appliances and to power a high-powered appliance, a different generator such as an alternator is used.
