As aspiring engineers, we are keen on using our creative problem solving skills to make a difference. In recent years there has been a lot of activity involving the production of efficient, renewable energy and energy-saving devices. The main objective of which, is to produce or conserve energy in a way that is cost effective and without having to use any valuable resources. The implementation of this technology in a community could assist its residents in saving a fair amount of electricity without them having to make any extra effort or spend any money at all. Together we have come up with a concept of a device which can be installed in a public pool. The amount of energy produced may not be huge, but it’s free and renewable which could add up to a great result.
Taking into account the amount of wave energy produced by the swimmers, we built a device which converts the kinetic energy of the water into electricity. It works by means of an impeller which is powered by the waves which passes through and causes it to spin. The mechanical movement of the impeller is converted into electricity by means of a hydroelectric generator. The impeller is housed in a cylindrical frame which is 35 centimetres in diameter and made out of carbon fibre. In order to get the most out of the device, we have to ensure that it is positioned strategically, submerged by about 40 centimetres and fixed to the wall. To prevent any foreign objects from entering the housing, all openings will be covered with a wire mesh filter. Before the device can be implemented we have to get the permissions from the council
