Construction
According to the Neil Young album title, rust never sleeps. In construction, rust damage can be insidious – especially in infrastructure like concrete bridges where rust can have fatal consequences if the steel in bridges fails. But detecting rust before it’s too late has been an ongoing challenge for engineers and scientists. Experts at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS have developed an early-warning system for rust. By installing sensor-transponders into in the concrete to measure the extent of corrosion, engineers are being given a vital heads-up. Read More
One of the world's greenest skyscrapers approaches completion
The 71-story Pearl River Tower, described as one of the most energy-efficient skyscrapers in the world, has reached its topping out milestone on the way to its planned completion later this year. (For those not in the architectural know, topping out or topping off is a ceremony held when the last beam is placed at the top of a building.) With a height of 309.6 meters the 2.3-million square-foot Pearl River Tower incorporates the latest green technology and engineering advancements, the most immediately obvious of which will be a pair of openings in the tower’s facade which feed wind turbines to generate energy for the building.

Could you confidently gallivant under huge mushroom-like structures knowing that they had been glued – not bolted – together? The architects and engineers of the “Parasols” in Seville, Spain, certainly hope so because the design features components that are stuck to each other in such a way. Understandably, they say the biggest problem was finding a glue that could withstand 60°C (140°F) and therefore wouldn’t melt in Seville’s summer heat. This is a fairly important criterion for the free-standing parasols that cover an area of 150m x 70m - one of the largest architectural timber structures ever built. Researchers from the Fraunhofer Institute for Wood Research WKI in Germany have adhered to the challenge and stuck with a formula they believe will do the job. Read More
Aside from tragic loss of life and incomprehensible destruction, events like last week’s devastating earthquake in Haiti create a myriad of problems in their wake, not least of which is homelessness. With over 30 million shipping containers the world over currently lying dormant, a team of researchers at Clemson University in South Carolina are working to help solve the issue of accommodation in disaster affected areas by developing a method to convert the unused containers into sustainable emergency housing.

3-D printing technology is maturing to the point where rapid prototyping machines are becoming affordable to small business owners - and even for high-end home use. Dimension's uPrint 3D printer has just been released at a retail price of US$14,900, giving anyone with CAD skills the ability to prototype and even manufacture pretty much any small shape they want in hard ABSplus plastic - including pre-assembled objects with moving parts. What would you create if you could have any plastic shape you wanted? Read More
Cambridge University PhD student Qi Pan has designed software that creates textured 3D models in slightly more than a minute using a stationary camera, such as a webcam. Conventional off-line model reconstruction relies on a number of phases - there’s an image collection phase that can be quite quick, followed by a very slow reconstruction phase, which requires a long time to verify a model obtained from an image sequence is acceptable. This new software creates a 3D model on-line as the input sequence is being collected. As the user rotates the object in front of a camera, a partial model is reconstructed and displayed to the user.

The world's first osmotic power plant from Statkraft
The principle of harnessing osmosis has the potential to produce enormous amounts of energy anywhere that salt water and fresh water meet. We looked at some of the approaches to turning this theory into reality earlier this year, including Statkraft's plans to build a prototype power plant. The company's plans are now coming to fruition with Her Royal Highness Crown Princess Mette-Marit of Norway officially opening the world's first osmotic power plant prototype on November 24.

A group of French students are getting ready to fly across the English Channel in the world's first solar powered airship. One hundred years after Louis Blériot won the coveted Daily Mail prize of £1000 by being the first to traverse the watery expanse in his 3-cylinder, 25 horse-power XI monoplane, the Projet Sol'r team will take to the skies in Néphélios, a 22 meter long airship capable of cruising at 30-35kph. Gizmag recently talked to one of the project's founders, Arnaud Vaillant. Read More
Demand for office and housing space in ever diminishing land space has led to taller and taller buildings reaching for the skies in cities around the world. This shortage of land in many cities has unfortunately also led to a scarcity of natural vegetation in urban settings. We’ve looked at several vertical-farming concepts - dedicated buildings that provide space to grow crops in city centers - but a new architectural system from Vertical Landscapes (VL) seeks to invite nature back into our cities on a broader scale. The architectural system transforms buildings into columns of vegetation to add a much needed touch of green, help clean the city air and possibly even produce small scale crops, all while retaining the building’s usual use for office or housing space.

Every child learns early on that moist sand is the key to building a sturdy sandcastle. Now researchers at Durham University have studied this principle so it can be better applied to an ancient eco-friendly building technique of using rammed earth. Read More
