  • Solar Power in Building Design
    Endorsements for Solar Power in Building Design Dr. Peter Gevorkian’s Solar Power in Building Design is the third book in a sequence of compre- hensive surveys in the field of modern solar energy theory and practice. The technical title does little to betray to the reader (including the lay reader) the wonderful and uniquely entertaining immersion into the world of solar energy. It is apparent to the reader, from the very first page, that the author is a master of the field and is weav- ing a story with a carefully designed plot. The author is a great storyteller and begins the book with a romantic yet rigorous historical perspective that includes the contribution of modern physics. A description of Einstein’s photoelectric effect, which forms one of the foundations of current photo- voltaic devices, sets the tone. We are then invited to witness the tense dialogue (the ac versus dc debate) between two giants in the field of electric energy, Edison and Tesla. The issues, though a century old, seem astonishingly fresh and relevant. In the smoothest possible way Dr. Gevorkian escorts us in a well-rehearsed manner through a fascinat- ing tour of the field of solar energy making stops to discuss the basic physics of the technology, manu- facturing process, and detailed system design. Occasionally there is a delightful excursion into subjects such as energy conservation, building codes, and the practical side of project implementation. All this would have been more than enough to satisfy the versed and unversed in the field of renew- able energy.

Furthermore, it represents my own opinions and not necessarily those of the Cape Peninsula University of Technology. Signed Date ii ABSTRACT The world has been experiencing energy-related problems following pressuring energy demands which go along with the global economy growth. These problems can be phrased in three paradoxical statements: Firstly, in spite of a massive and costless solar energy, global unprecedented energy crisis has prevailed, resulting in skyrocketing costs. Secondly, though the sun releases a clean energy, yet conventional plants are mainly being run on unclean energy sources despite their part in the climate changes and global warming. Thirdly, while a negligible percentage of the solar energy is used for power generation purposes, it is not optimally exploited since more than its half is wasted in the form of heat which contributes to lowering efficiency of solar cells and causes their premature degradation and anticipated ageing.

  • THE QUIET ACHIEVER' BP SOLAR CAR CROSSING of AUSTRALIA Perth to Sydney Sunday 19 December 1982 to Friday 7 January 1983
    ‘THE QUIET ACHIEVER' BP SOLAR CAR CROSSING OF AUSTRALIA Perth to Sydney Sunday 19 December 1982 to Friday 7 January 1983 'THE LITTLE CAR THAT COULD' Tom Snooks was the Project Coordinator and he has compiled a record of the BP Solar Trek, using press clippings from the day, a video made on the project, monitoring records, and memories. A great shot of The Quiet Achiever traveling through outback New South Wales. 1 THE QUIET ACHIEVER An endurance test, the first of its kind ever held anywhere in the world, occurred in Australia in late 1982/early 1983. It was conducted under the auspices of the Confederation of Australian Motor Sport (CAMS). This test was the first trans-continental crossing by a solar-powered car, when Hans Tholstrup and Larry Perkins successfully completed the historic BP Solar Trek across Australia, when they brought 'The Quiet Achiever' from Perth to Sydney. They had no overseas technology to draw on, no plans to follow, no previous mistakes to look at or learn from, yet in eight months they designed and built a whole new machine that ran for over 4000 kilometres with only some broken wheel spokes and a number of punctures. They took 20 days to make the crossing, but had all the roads been as smooth after Wilcannia when they covered 307 and 287 kilometres, they could have run the vehicle in high gear and completed the trip in around 14 days. Hans got the idea for the trek in 1980 when the combined pedal and solar powered 'Gossamer' plane flew across the 35 kilometre English Channel.

ANNAPURNA1,3 In the present day knowledge based society, Science transforms the Culture. This can be witnessed through the contemporary rationalized society that aroused with the advancement of science. Such revolutionised change leading to very fast modern-day walks of life can essentially be credited to the progression in light based technologies. However, in order to meet the continuously mounting demand for energy in this developed world, one has to look for the renewable energy resources and among all such resources most abundant one is the sunlight. In this context, an attempt has been made here to report a brief review on the development of solar cell, the simplest device that converts sunlight to electricity. Further, this article also presents the contributions of CSIR-CGCRI in this field. Introduction manufacturing industries, retail market, geology, atmospheric physics and optical communications, to name part from being one of the indispensible a few. The development of optical fibres enabled faster component of nature for existence of life on earth, and easier communications leading to instantaneous data the light, has widely been explored by mankind A transfer within a fraction of second through internet to meet with his basic needs in every stages of connections across the world, thereby connecting people development. Light based technologies began to develop irrespective of their geographical locations. Thus in the with the invention of incandescent bulb to meet with the present era, light based technologies have become vital for requirement of vision during night.

  • The Next Car You Buy Could Be a Solar Powered Car So Can Solar Powered Cars Ever Become a Reality?
    The next car you buy could be a Solar Powered Car So Can Solar powered cars ever become a reality? Australia has a long history and involvement with the development of solar powered cars, starting with the Quiet Achiever in 1983. An all battery powered vehicle designed and built by Larry & Garry Perkins and world famous adventurer Hans Thorstrup, little did they know that their crossing of Australia from Perth to Sydney at a thundering average speed of 23km/h would inspire a whole generation of young engineers from all over the world to not only duplicate this earlier achievement, but to take the concept and turn it into the reality of a solar powered, sustainable family vehicle. Are we there yet? the short answer is no. Yes, we have manufactures who can supply a variety of electric and electric- hybrid vehicles in Australia today. Alas there a no commercial solar powered family cars available in Australia, and even if there where, at the moment, the price of such a vehicle would be so astronomical that very few would or could afford or benefit from such a vehicle. But still we dream and strive to build for the future. Every two years around 40 solar powered cars from more than 20 countries, race 3,000 km across the center of Australia from Darwin to Adelaide, taking part in the Bridgestone World Solar Challenge. For years this event has been the showcase for solar car racing and allows the opportunity for Electric Vehicle manufactures to meet the local and international teams, get to see the cars up close and snap up the best and brightest young engineers in battery pack development, systems and aerodynamic engineering.
