For several years, South Africa has battled with its high emissions of greenhouse gases (GHG). The country has an abundance of coal reserves, which it relies on heavily for energy. Another major contributor of GHG is the industrial sector which is fundamental in the country’s economic activities.
Engineers are often prone to making mistakes. That is why we constantly have to check and double-check everything that we do. It is this type of keen focus on what we do that allowed generations of past engineers to create some of the most remarkable engineering projects. However, details are sometimes overlooked, numbers misrepresented or even units misread. While some of these mistakes are miniscule and can be corrected, history has witnessed some colossal oversights that led to huge disasters and in some cases, popular travel destinations.
The longest ocean-crossing bridge in the world, the Hangzhou Bay Bridge is an S-shaped stayed-cable bridge with six lanes in both directions that shortens the distance between Shanghai and Ningbo by 120 kilometers. The 36 kilometer long bridge required a great number of new techniques, new materials, new equipment and new theories due to the large scale and design of the project. It took close to 600 experts and a total of nine years to design the bridge. The Hangzhou Bay Bridge is expected to boost the economic development of the Yangtze River Delta, also called the Golden Industrial Triangle. Work on the bridge began in June 2003 and was completed in June 2007. The bridge was opened to the public in May 2008 and carried about 50,000 vehicles per day in its first year of operation. The total project cost was approximately $1.5 billion.
Towering majestically on Taiwan’s skyline, the Taipei 101 was the first world’s tallest building completed in the 21st century and remains the first building in the world to break the half-kilometer mark in height. It was surpassed by Burj Khalifa in Dubai in 2010 though it remains a significant structure globally. Completed in 2004, the building stands at 508-meters and has 101 floors. A prominent icon in Taiwan, fireworks launched from the tower on New Year’s Eve has become an international broadcast and it is featured frequently in international media.
It is that time of the year again, when gift-giving becomes a requirement at most social functions. We therefore feel obligated to continue our gifts for engineers articles, a series of articles intended to demystify the peculiar tastes of engineers. From books to electronics this list is a continuation of what we feel if a public service for the benefit for all. The following list provides a delightful collection of gifts that engineers will appreciate the subtle engineering themes.
A thriller that puts engineering in the spotlight by making an engineer the main character and hero, The Jackhammer Elegies, recently won an entertainment industries award for highlighting the profession.
Built from 1874 to 1876, The Tehachapi Loop was built to connect California’s fertile San Joaquin Valley with the then small agricultural town of Los Angeles on California’s southern coast. Originally, the plans mapped out indicated that the Tehachapi Line would bypass Los Angeles and instead go southeast through the Mojave Desert to Yuma, Arizona, and all points east. Eventually state politics overruled the Southern Pacific’s decision, which was the company that monopolized railroad transportation in California at that time.
One of the major functions of an engineer is to improve the quality of life of humans around the world.

Over time, there have been some inventions that completely revolutionized the working dynamics of the world.
The world “renewable” has quickly become a synonym of words like “clean”, “environmentally friendly” and “sustainable” in our language. Even the companies and governments have used it with commercial, informative and even propagandist goals. The truth is that “renewable” stuff is part of contemporary life since some years ago, especially when energy is involved.
