Engineering Executive Status Achievement

It’s incredibly humbling and satisfying when the governing body of your profession recognises your hard work and dedication.

I have achieved the status of Engineering Executive, so many thanks to the Institution of Engineers Australia for this terrific honour.

I am now Charted in the following areas of practice:
• Civil Engineering
• Structural Engineering

Linear friction welding

Linear Friction Welding

Linear friction welding is a process that uses heat from friction to weld things.  It can join materials extremely fast. It can take as little as a second to complete.

Why else it this method used?

  • In addition to speed, there are a few other benefits. Very little prep is needed. Surfaces do not need to be thoroughly treated beforehand.
  • The method produces no harmful fumes. Unlike traditional welding methods

How friction welding is done?

The materials are placed inside the welding machine. They’re then tightly pushed together. One material moves quickly against the other. This creates a lot of friction. The resulting heat joins the parts together. It’s the preferred method for assembly of turbine engines. But it is also used to build cars, ships and trains.

Connected Vehicle: The Future of Transportation

What is a connected vehicle?

In general, the term ‘Connected Vehicle’ is used to broadly identify any ‘smart vehicle’ with:

  • wireless connectivity to the Internet
  • local network or the Cloud
  • other vehicles
  • personal communication devices
  • roadside infrastructure
  • control centres for real-time communication or exchange of data.

Benefits of Connected Vehicles

  • reduce the number of fatalities
    and serious casualties caused by
    road crashes
  • reduce the costs associated with
    road trauma
  • reduce traffic congestion
  • improve productivity in road
    infrastructure use
  • reduce the environmental impacts
    of road transport, through less
    emissions and fuel use

Could seaweed be the solution to our growing plastic problem?

David Christian, founder of Evoware certainly thinks so. Evoware is a socially responsible enterprise that elevates an environmentally friendly lifestyle and provides innovative value to urban society. Their mission is to create innovative solutions from seaweed to solve plastic waste issue, while increasing the livelihood of Indonesia’s seaweed farmers.

Why they do what they do

Environmental Issues

  • Indonesia is the world’s second biggest plastic waste contributor to the ocean
  • 90% of plastic waste go into the ocean; 70% of that waste comes from food and beverage packaging
  • There will be more plastic than fish in the sea by 2050
  • 25% of fish in Indonesian market are contaminated by plastic

Seaweed Farmer Issues

  • A large volume of seaweed production is not used/oversupply
  • Most seaweed farmers are poor due to a long marketing chain and loan sharks
  • 5 of the 6 poorest provinces in Indonesia are actually producing seaweed

Zaha Hadid Architects and ETH Zurich develop knitted concrete system

A double-curved concrete shell made with a 3D-knitted formwork in a collaboration between Zaha Hadid Architects and ETH Zurich has gone on display in Mexico City.

KnitCret is a new 3D-knitted textile system for creating curving concrete structures, without the need for expensive and time-consuming moulds.

The colourful pavilion is called KnitCandela in homage to the work of Spanish-Mexican architect and engineer Félix Candela, who created dramatic curved concrete shells in his buildings such as the Los Manantiales Restaurant in 1958.

Over two miles of yarn was knitted into four strips of between 15 and 26 metres in just 36 hours using a digital fabrication technique, then flown over from Switzerland to Mexico in suitcases.

World’s longest sea crossing bridge opens in China

The Hongkong-Zhuhai-Macoa bridge is now officially open. The bridge is 55-km long. It consists of a 22.9-km main bridge and a 6.7-km underground tunnel.  Surface area of the bridge is 700,000 square meters. It’s about the size of 98 standard football fields. Its main girders are made up of 420,000 tons of steel plates. The weight is equal to about 60 Eiffel Towers. It has the world’s longest immersed tube highway tunnel. The rubes reach a depth of up to 40 meters underwater. The bridge is curved as its piers are placed in the direction of water flow.

Car-free, more livable cities

Car-free, more livable cities

Here are 3 cities that have banned cars with amazing results.

  • Ljubljana, Slovenia – The streets in this city are filled with chatting pedestrians rather than traffic. If you live in the centre, you must park in a garage outside the car-free area. And if you’re elderly, disabled or a mother with children, you get free rides in electric taxis. Business and tourism have increased since the ban more than 10 years ago.
  • Pontevedra, Spain – This city banned cars 19 years ago. 70% of trips in the town are now on foot. And because the town is more livable, 12,000 people have moved into the centre. And air pollution has decreased by 61% since 2013.
  • Copenhagen – This city has over 96,000 square metres of car-free space. Two thirds of people commute by bike. And from 2019, it plans to ban new diesel cars to make its air even cleaner.

Our cities here in Australia should adapt this wonderful initiative. What do you reckon?

Least stressful cities in the world

Germany has the least stressful cities in the world. German cities have a large number of green spaces, low levels of traffic, and high levels of wealth. Four German cities make the top 10 of chilled out cities and Stuttgart is the most stress-free city on the planet. Sydney was the only non-European city to feature. With the rest of the top 10 made up by:

  • Graz, Austria
  • Edinburgh, UK
  • Bordeaux, France
  • Bern, Switzerland
  • Luxembourgh

Water pipe turbines generating clean energy

American cities are putting turbines in water pipes to generate clean energy with zero environmental impact. In Portland, water mainly comes from the surrounding mountains. Gravity forces the water down the pipes, spinning the turbines and creating a source of clean energy under the ground. Because gravity is the force that moves the water, no extra energy needs to be used. Riverside, California is also installing turbines in water pipes. They generate enough energy during the day to power the water system itself and at night the turbines keep the street lights on.

Portland has installed turbines in 15 metres of pipes as a trial at a cost of 1.7 million dollars. They generate around 1,100 megawatt-hours of electricity every year. Enough to power about 150 homes and cut back on the use of polluting fossil fuels.

Should Australian cities install turbines in its water pipes too?
