With climate change wreaking havoc around the world, it is imperative that Australia develop more technologies to secure the future of Australia and our Pacific Island neighbours. While solar panel farms and wind farms have begun the process, it is imperative that Australia widen the use of solar energy to replace more facilities formerly emergised with gas and coal-fired electricity as well as avoiding the costly use of cross-country transmission systems. The use of heliostats could provide solutions for big industries, pottery kilns and metallurgical heat treatments. This study promotes the application of elementary spherical trigonometry to a study of a heliostat consisting of a single mirror or an array of mirrors. In this way the alignment of the axes and the rate of rotation about the axes were calculated to achieve predicitve tracking of the sun. It is intended to establish the possibility of linking an array of mirrors mechanically, which focus several kilowatt hours (kWh) of the sun's energy onto a black body receiver for a whole day in any month of the year. Calculations show that each mirror needs only to be rotated about a single axis on a single day. In the early stages of development, the master spindle could be cranked by hand. Future developments could include an automated tracking system to optimise the results. [ABSTRACT FROM AUTHOR] |
