Melbourne to Sydney in just 53 minutes?

Thanks to Hyperloop Technology, travelling from Melbourne to Sydney could be hopefully done in under one hour!

But what is Hyperloop? And how is it going to change our travelling lives for the better?

The Hyperloop is the future of transport. It’s a new way of moving that is faster, cheaper, safer, and more efficient than anything that exists today. Air-tight pods fly through a near-vacuum tube, travelling up to 1000km/h, to get you or your freight to destination in the quickest way possible. The brainchild of visionary Elon Musk – CEO of Tesla Motors, SpaceX, PayPal, Solarcity and OpenAI – Hyperloop is the fifth mode of transport after planes, trains, cars and boats. Hyperloop strives to significantly minimise travel times, reduce carbon footprint and lessen the cost of travel while emerging as the safest mode of transport.

Hyperloop has significant advantages for travelers, the economy, and the environment. Eventually, it will be able to travel far faster than any method of land based transport currently available — with its closest competitor, the bullet train, only capable of speeds of 320 km/h (200 mph). Projections indicate that it will also be cheaper to build than bullet train systems.

VicHyper wants to revolutionise the future of transport in Australia. Their CEO, Zac McLelland who is based at RMIT, said the hyperloop technology which had the potential to leapfrog fast rail and link the cities with ease, existed. It was now just a matter of putting it into practice. “If we really wanted to do it, we could do it now, and be built within three to five years,’’ Mr McLelland said.

The world’s future megaprojects

This is a fascinating documentary on eight of the most ambitious mega-projects currently under development around the world, featuring: Istanbul’s building boom (Turkey); the Mission to put a human on Mars; the effort to develop Lagos (Nigeria); Africa’s unprecedented clean energy opportunity; the project to probe the nearest Earth-like exoplanet; Atlanta’s stadium of the future (Georgia, United States); India’s effort to modernize its highways; and China’s unprecedented One Belt One Road, “New Silk Road” initiative.

China’s “One Belt, One Road” worldwide project is the one to watch. It starts at 34.22 if you want to skip the rest. Its magnitude and scope is nothing like we’ve ever seen before.  At an approximate cost of $US1 trillion of projects funded by China’s state-run banks, major infrastructure works in Africa and Central Asia have already been initiated. It will involve 65 countries with a total population reach of 4.4 billion and a share of global economy of 30 per cent. It’s more than seven times larger than America’s Marshall Plan to rebuild Europe after the Second World War.

It’s a massive project with many roads, railways, ports and maritime routes making up new and revived trade corridors. The land-based projects are the belt. The road is the maritime routes that will connect up China’s southern provinces to south-east Asia and the east coast of Africa with ports and railways.

For those who are uninitiated, the “Silk Road” was an ancient network of trade routes that were for centuries central to cultural interaction originally through regions of Eurasia connecting the East and West. The Silk Road concept refers to both the terrestrial and the maritime routes connecting Asia and Europe.

While the term is of modern coinage, the Silk Road derives its name from the lucrative trade in silk (and horses) carried out along its length, beginning during the Han Dynasty.

Five most famous bridges

We just love bridges. They come in all shapes and sizes and play a major role in uniting our communities and enhancing our everyday life. Here we highlight five of the most famous bridges in our world today starting with our very own Coathanger.

Sydney Harbour Bridge

The Sydney Harbour Bridge links Sydney’s two major commercial centres and forms a daily orientation point for millions. It is a living landmark, a tourist experience and an essential transport line for Sydneysiders. It is a cultural landscape that people actively experience: driving, walking, sailing, flying, cycling, ferry and train commuting, as well as passively observe – from the foreshores, from a distance, as a distinctive landmark – or examine in detail as a marvel of engineering technology.

Golden Gate

The Golden Gate bridge is still considered one of the world’s engineering masterpieces. Today it carries over 100,000 vehicles per day (northbound and southbound). The Golden Gate has endured as a marvel of modern engineering; its 4,200-foot main span was the longest for a suspension bridge until 1981, while its 746-foot towers made it the tallest bridge of any type until 1993. It withstood the destructive Loma Pieta earthquake of 1989, and was closed to traffic only three times in its first 75 years due to weather conditions. Believed to be the most photographed bridge in the world, this landmark was named one of the seven civil engineering wonders of the United States by the American Society of Civil Engineers in 1994.

Qingdao Haiwan Bridge

In 2011, the Qingdao Haiwan Bridge became the world’s longest sea bridge. At 42.6 km long, it is nearly 5 kilometers longer than the previous record-holder, the Lake Pontchartrain Causeway, in Louisiana, USA. Costing $8.6 billion, the bridge links Qingdao city in China’s eastern Shandong province with the Huangdao district. The former is considered as the national tourism city of China and Huangdao is a suburban region which is moving towards becoming the next booming economic region. And the bridge is, therefore, is a great asset for tourism and trade.



Øresund Bridge

The Øresund Bridge is an approximately 16-kilometer long road and rail link between Sweden and Denmark. It connects Copenhagen to Malmö fostering economic growth and cooperation for both cities. The link consists of three sections, a bridge, an artificial island and a tunnel, and the bridge accounts for half the length, with a railway and motorway running on separate levels. The bridge has provided a foundation for stronger and more extensive cooperation regarding economy, education, research and culture between Sweden and Denmark.

Millau Viaduct

Millau Viaduct is ranked as one of the great engineering achievements of all time. It opened in 2004 and was built across the Tarn valley to alleviate holiday traffic between France and Spain. This bridge broke several records. It has the highest pylons in the world (245 meters and 221 meters), the highest bridge tower in the world (343 meters) and the highest road bridge deck in Europe (270 meters). Millau Viaduct is so high that it glides above the clouds.  In 2006, Millau Viaduct received the Outstanding Structure Award by the International Association for Bridge and Structural Engineering.

How to build higher?

In this video we will learn about vortex shedding and mass dampers.

What is Vortex Shedding?

Vortex shedding happens when wind hits a structure, causing alternating vorticies to form at a certain frequency. This in turn causes the system to excite and produce a vibrational load. Historically, it has been very difficult to calculate by hand. Today, with modern technology and new engineering practices, completing a vortex shedding analysis is a valuable tool used in the design of tall equipment and structures.


What is Mass Damper?

Mass Damper is the system that’s used to control movement in skyscrapers by reducing both the speed at which the building oscillates and the distance those oscillations cover. Mass dampers consist of large pendulums—usually steel plates bolted together to form a solid chunk—suspended from cables near the top of the building. When the building sways in a gust, the weight’s inertia acts as a counterweight, pulling it in the opposite direction.

Five famous female engineers

In honour of the Queen’s birthday, we thought we’ll revisit history and highlight some of the most famous female engineers of our time.

Emily Warren Roebling (September 23, 1843 – February 28, 1903)

Emily Warren Roebling was responsible for one of the USA’s most famous landmarks – the Brooklyn Bridge.  Her husband, Washington Roebling was a civil engineer and the Chief Engineer during the construction of the Brooklyn Bridge. He unfortunately succumbed to caisson disease and the task of completing the bridge fell upon Emily. She was able to relay information between her sick husband and the workers. But she also studied intensively (and learned from her husband) and soon developed an extensive knowledge of strength of materials, stress analysis, cable construction, and calculating catenary curves. For the next 14 years Emily oversaw the bridge project, dealing with politicians, competing engineers, and all those associated with the work on the bridge. The Brooklyn Bridge was finally completed in 1883 and Emily Roebling was the first person to cross it by carriage.

elmina wilson

Elmina Wilson (September 29, 1870 – June 4, 1918)

Elmina Wilson is known as the “first lady of structural engineering”. She was the first woman to receive a Bachelor of Civil Engineering degree at Iowa State University (ISU), and the first one to complete her master’s degree in the field.  Professor Anson Marston, a man of progressive values who was also the Dean of Engineering at ISU became her mentor. She collaborated with him to build the 168-foot-tall Ames, Iowa, water tower, the first raised steel tower west of the Mississippi.

Nora Stanton Blatch

Nora Stanton Barney (September 30, 1883 – January 18, 1971)

Nora Stanton was the first female member of the American Society of Civil Engineers. She was born in Basingstoke, England on September 30, 1883. As a small child, her family moved to New York. In 1905, she was the first woman to graduate from Cornell University with a Civil Engineering degree. That same year, she became the first female member, with junior status, of the American Society of Civil Engineers (ASCE) and began work for the New York City Board of Water Supply. Nora, like her grandmother Elizabeth Cady Stanton, was involved in work for world peace and women’s rights. In 1915, she became the president of the Women’s Political Union. She participated in the efforts for a federal Equal Rights Amendment. In her later years, she remained politically active, writing pamphlets such as Woman as Human Beings and World Peace Through a Peoples Parliament.

Olive Dennis

Olive Dennis (November 20, 1885 – November 5, 1957)

Olive Dennis was the first woman to become a member of the American Railway Engineering Association. She was one of the first women to obtain a Civil Engineering degree from Cornell University. She strived hard and eventually began working for the Baltimore and Ohio (B & O) Railroad. Since half of the railroad’s passengers were women, it was felt that a woman would be better suited to handle engineering upgrades in service. Thus Olive Dennis was made the railroad’s first “service engineer” and assigned the responsibility of improving passenger service. In a career spanning over three decades, she worked hard to make travelling as comfortable as possible for the passengers.

Elsie Eaves  (May 5, 1898 – March 27, 1983)

Elsie Eaves was the first woman to be a full member of the American Society of Civil Engineers. In 1920, at the age of 22, she graduated from the University of Colorado with a Civil Engineering degree. After graduating from college, she worked for the U.S. Bureau of Public Roads, the Colorado State Highway Department, and the Denver and Rio Grande Railroad. In 1945, she became the manager of Business News and continued there until she retired in 1963. After retiring, she became an advisor to the National Commission on Urban Affairs on the subject of housing costs. She also advised the International Executive Service Corps about construction costs in Iran. In 1957, she was the first woman to join the American Association of Cost Engineers, where she eventually became the first woman to be awarded an Honorary Life Membership.

Why build higher?

First, the exploding population, largely urban, creates an increasing demand for tall buildings. The ever increasing population and growing economies in major cities of the world mean increasing urbanization globally and the continuing rise in population density in urban areas. Arable land areas are constantly being eaten away by urban spreading through suburban developments. The tall building can accommodate many more people on a smaller land than would be the case with low-rise building on the same land. A tall building is in effect a vertical transformation of horizontal expansion.

Second, it is generally [acknowledged] that there has been evident neglect of the human factors in urban design at the expense of livability and quality of life. The outward expansion of cities into the suburbs has resulted in increased travel time and traffic gridlock. The prospect of traveling for a long time, to and from work, is detrimental to social well-being of the commuter and results in losses of fuel and productivity. Clustering of buildings in the form of tall buildings in densely built-up areas is the opportunity for creating open spaces like playgrounds, plazas, parks, and other community spaces by freeing up space at the ground level. Besides the impact on the city skyline, tall buildings thus influence the city fabric at the level where they meet the ground. The improvement of the “ public realm ”has become a necessity exerted by planning authorities in major cities.

 Tips for up and coming engineers

Tips for up and coming engineers

Let me start by saying that being an engineer is an incredibly rewarding yet demanding career choice.

As ‘corny’ as it sounds, you will make a real difference in people’s lives, and as cliché as this sounds, ‘engineers really do make ‘it’ happen’.

Unfortunately when you’re first starting out, it can be an incredibly daunting and frustrating time for a young engineer, so here are five tips for my ‘brethren’ beginning their engineering journey.

  1. For A Short Period of Time It’s Going To Hurt

Graduating with a degree in engineering is an accomplishment in and of itself. Unfortunately the reality is that your degree is essentially a piece of paper that verifies you know how to use a calculator and chew gum at the same time.

Of course I am being facetious, but the end of your degree is actually the first step on a very long road ahead. You need to accept that for the first three to five years you will be confused and shrouded in self-doubt, constantly second guessing yourself as you struggle to make sense of the monumental amount of information you will be asked to absorb and comprehend.

Fight through that self-doubt. You’re going to be fine.

Grit your teeth, keep your eyes and ears open, commit to your growth, focus on your development and absorb as much as you can as quickly as you can, and before you know it you will have set the foundations of your career.

  1. Site Experience, Site Experience, Site Experience

In case it wasn’t emphasised enough, you’ve got to get site experience. It is unbelievable how important working in the field can be. Get on site and get dirty. For the first six months to a year, work as a labourer if you must, it doesn’t matter, just get out there. Site work will give you incredible insight that an office environment simply can’t, plus it will enable you to think beyond the numbers and formulas and expose you to factors and parameters you won’t learn from a text book.

  1. A Strong Work Ethic Is Mandatory

As an engineer, you will encounter countless variations of never ending problems from demanding clients that set ‘yesterday’ deadlines in an industry where competition grows exponentially, thanks to the wonders of ever changing technology.

There is simply too much information to process, and of course there never is enough time, so believe me when I tell you that 9-5 won’t cut it. Success requires early starts and late finishes, so forget about looking at your watch and repeat this mantra over and over:

  1. Modern Tech is A Double Edge Sword So Measure Twice Cut Once

One of the great things about modern engineering is the vast number of advanced tools we have at our disposal. Computers and modern technology have allowed us to tackle complex problems, communicate big ideas and share results faster and more efficiently than ever before.

In fact this piece was typed on a laptop connected to the internet via my Australian mobile phone connected to the Chinese network whilst sitting in a bullet train travelling at 305km/hr heading to Shenzhen to meet with Chinese engineering colleagues to discuss new concrete and steel technology.

Unfortunately, surrounded by all the modern tools, an engineer can become lazy and too trusting of the solution on the screen. Whether it’s a complex FEM program or a simple spreadsheet, you must develop a full and comprehensive understanding of the input ‘language’ to properly interpret the output results.

Do not rush to the keyboard before first developing your understanding of engineering philosophy and a ‘feel’ for the numbers.

My advice is simple, respect technology, don’t be afraid to use it, but apply a healthy dose of scepticism when reviewing the output file, and if it doesn’t ‘feel’ right, then check it with a hand calculation. Then check it again.

  1. Money Money Money Money Money

Do not let money be the main factor which determines the course of your career, because when you’re starting out, you will not be impressed by your pay cheque.

Don’t worry about money during the early stages.

First choose the branch/sector of your engineering discipline which most interests you, then focus on developing your skills and technical abilities.

It’s no secret or special advice, love your job and it won’t feel like work, and before you know it your knowledge base and ‘abilities’ will start expanding exponentially and you will become more ‘valuable’ to an organisation.

That’s when you start seeing the bigger numbers and that’s when other options start to appear.

Never step on a crack again!

Paved roads are nice to look at, but they’re easily damaged and costly to repair. Erik Schlangen demos a new type of porous asphalt made of simple materials with an astonishing feature: When cracked, it can be “healed” by induction heating. Amazing!

Why you should listen?

Erik Schlangen is a Civil Engineering professor at Delft University of Technology and the Chair of Experimental Micromechanics. His areas of research include durability mechanics and “self-healing” materials, like the asphalt and concrete he and his team have developed that can be repaired with induction. This special asphalt is made with tiny steel wool fibers, which, when heated with induction, extends the life of the material. Currently Schlangen and his team are testing the asphalt on the A58 road near Vilssingen in the Netherlands, with the hope that it can be used in future roads all over the country.
