The world’s largest tunnel boring machine is being put to work in Seattle

Bertha, the world’s largest tunnel boring machine (TBM), started digging under Seattle on Tuesday as it chewed through the north wall of the 80-ft (24.3 m) deep trench where it was assembled after being shipped in pieces from its manufacturer in Japan. Designed to bore a 1.7 mi (2.7 km) tunnel for State Route 99 (SR 99) under the Seattle city center to replace the old viaduct, the machine will both dig out soil and lay a concrete tunnel wall as it goes.  Read More

On Saturday, a tunnel boring machine (TBM) so large that it looks like something out of Thunderbirds was dedicated in the city of Seattle. “Bertha,” as it’s known, is the world’s largest TBM and will spend the next 14 months boring a 1.7 mile (2.7 km) tunnel under the city as part of a US$3.1 billion project to replace a viaduct damaged in a 2001 earthquake. As part of a press tour, the Washington State Department of Transportation (WSDOT) allowed Gizmag inside the giant machine.  Read More

Stratolaunch Systems has announced new developments in its air launch system for spacecraf...

Back in December of 2011, Stratolaunch Systems announced that it was designing a new air launch system for both manned and unmanned spacecraft. Among other things, that system would require the construction of what would be the world’s largest aircraft. While some people might understandably be skeptical of such grand plans ever seeing the light of day, the company recently announced that a couple of important milestones have been reached that bring the project closer to fruition.  Read More

The 1:1 scale Lego X-Wing is unveiled in Times Square

A certain Jedi Master, species unknown, once said, “size matters not.” But he obviously wasn’t referring to the latest Lego creation from the Lego group. Taking the title of the world’s largest Lego model is a 1:1 scale replica of an X-Wing made up of 5,335,200 Lego bricks and taking 32 Lego master builders 17,336 hours (around four months) to complete.  Read More

The southern half of the stadium will boast the world's largest transparent roof

The Minnesota Vikings American football team has announced the final design for a new stadium to built in the Minneapolis city center that will feature the world’s largest transparent roof.

Lockheed Martin and Reignwood Group plan to develop a 10 MW prototype OTEC pilot plant off...

Lockheed Martin has been getting its feet wet in the renewable energy game for some time. In the 1970s it helped build the world’s first successful floating Ocean Thermal Energy Conversion (OTEC) system that generated net power, and in 2009 it was awarded a contract to develop an OTEC pilot plant in Hawaii. That project has apparently been canceled but the company has now shifted its OTEC sights westward by teaming up with Hong Kong-based Reignwood Group to co-develop a pilot plant that will be built off the coast of southern China.  Read More

The 630-MW London Array is now online and generating

Phase one of the London Array usurped the UK's Greater Gabbard to become the largest operational offshore wind farm in the world when its final turbine (its 175th) was commissioned on Saturday afternoon. Though construction was completed back in December, it is only now that all of the farm's turbines are supplying the UK's national grid with electrical power. The array has a total capacity of 630 MW.  Read More

Bulgarian-born artist Christo has unveiled his latest work, dubbed “Big Air Package,” which is billed as the largest indoor sculpture created to date. Whether the claim is true or not, the installation is most certainly a significant feat of engineering in its own right. Big Air Package is installed in Germany’s Gasometer Oberhausen, and almost fills the cavernous space of an empty gas tank, the inflated envelope being 90 meters (295 feet) high, and 50 meters (164 feet) in diameter.  Read More

The Shams 1 concentrated solar power plant covers and area of 2.5 square km (1 sq mile)

Thanks to its low latitude and low percentage of cloudy days, the United Arab Emirates (UAE) is an ideal location for capturing solar energy. So it’s no surprise to see the world’s largest operating concentrated solar power (CSP) has launched in the sun-soaked Middle Eastern country. Officially inaugurated this week by UAE President and Ruler of Abu Dhabi, Sheikh Khalifa bin Zayed Al Nahyan, Shams 1 is a 100 MW CSP that will power 20,000 UAE homes.  Read More

The snowflake design will house six indoor and two outdoor slopes in its three intersectin...

Danish architecture firm CEBRA is working with the travel company Danski on a proposal for a huge alpine style ski dome to be situated in the city of Randers, Denmark. The ski park will provide over 3 km (1.86 miles) of indoor and outdoor slopes under its snowflake-inspired arches and if built it will take over from SkiDubai as the largest indoor ski park in the world at 100,000 square meters (1,076,000 sq.ft).  Read More
