FLOWLIGHT is a renewable energy product, which sources its energy from the flow of a tidal river to create a quayside street lighting product. For the example of this concept project FLOWLIGHT, all data collected and presented on this design is based on a tidal river called the River Suir which passes through the old Viking city of Waterford in the south east of Ireland. Using Waterford as the location of this concept also demonstrates how old and new can complement each other. The outer shell of the product is made from a Carbon Fibre material, which expresses an element of marine design. Part of the product consists of uniquely designed Water Turbine Blades, which are mounted on an outer rim. The Turbine Blades are protected by a Sub-Floatation Housing Unit which also protects the Blades from hitting the river bed and being damaged. The FLOWLIGHT is designed with a Tidal Drop Extension Arm which constantly keeps the Sub-Floatation Housing Unit at the correct depth under the water. This arm continuously extends and contracts depending on the level of the water in the river. The FLOWLIGHT generates mechanical energy from the Water Turbine Blades and from this, the generator creates electrical power. This energy is stored in the product’s Battery Unit, which can be used when required to illuminate the LED Strip Lighting. Once daylight levels fall below a particular level, the Light Sensor switches the FLOWLIGHT LED Strip Light on. The light from FLOWLIGHT can light an area of 15 metres radius.
