“E-Ferry Ellen”, the world’s largest all-electric ferry, has made its maiden voyage connecting the island of Aerø, population 6,000, to the rest of Denmark. The route is 22 nautical miles long.
The ferry, which now connects the Danish ports of Søby and Fynshav, was built at the shipyard on the island of Als through a partnership between Aerø Municipality and the European Union. The project is part of Danish Natura, which aims to provide environmentally friendly transport for local residents. It was initiated in 2015 and was funded by the EU through the Horizon 2020 and Innovation Program.
The ship, capable of carrying 30 vehicles and 200 passengers, is powered by a battery system with an unprecedented capacity of 4.3MWh provided by Leclanché SA (SIX: LECN), one of the world’s leading energy storage companies. The operators estimate the electric ferry will save over 2,000 tons of CO2 per year in its operation.
Recent innovations in engineered timber have laid the foundations for the world’s first wooden skyscrapers to appear within a decade, a feat that is not only achievable—according to the Centre for Natural Material Innovation—but one they hope will beckon in an era of sustainable wooden cities, helping reverse historic emissions from the construction industry.
The research team based at the Faculty of Architecture, is interdisciplinary, composed of architects, biochemists, chemists, mathematicians and engineers, who specialise in plant-based material, including cross-laminated timber, arguably the first major structural innovation since the advent of reinforced concrete, 150 years ago.
The unique architecture project “Smart Slab” combines the excellent structural properties of concrete with the geometric freedom of 3D printing. It allows for the creation of highly optimised building components with complex structural configuration out of concrete. The Smart Slab in DFAB HOUSE is the first full-scale architectural project to be fabricated using 3D-printed formwork.
The project Smart Slab is a collaborative project of the Digital Building Technologies Group (project lead), the Chair of Physical Chemistry of Building Materials, and the Chair of Structural Design at ETH Zurich. It is for the first time implemented as part of the DFAB HOUSE project at the Empa and Eawag NEST research and innovation construction site in Dübendorf.
The city is planning to build it by 2020. The dynamic tower hotel was designed by David Fisher in 2008. Now it’s finally coming to life. Each floor of the 80-story building will rotate independently giving guests and residents a 360 degree view. An apartment could cost you up top $40 million.
The WasteShark is designed after one of nature’s most efficient harvesters of marine biomass, the Whale Shark. It is designed to swim through water and eat its prey with minimum effort and maximum efficiency.
It is designed for round-the-clock waste collection. It also scans and monitors the environment, sending data back to central command.
Purpose: 16 hours a day waste collection; data collection & transmit
Dubai has taken a step further along the road to making such dreams a reality by announcing that 25% of the city-state’s new buildings will be made using 3D printers by 2025.
The move is part of an ambitious 3D-printing strategy announced in 2016 by Sheikh Mohammed bin Rashid Al Maktoum, vice-president and prime minister of the United Arab Emirates and the ruler of Dubai.
The 3D-printing strategy aims to reduce labour by 70% and cut costs by 90% across different sectors, according to the Dubai Future Foundation.
Perhaps more crucially, 3D-printing construction has the potential to help solve a looming homelessness crisis as more people gravitate to living in cities: the UN predicts that by 2030, the world will have 41 mega-cities with more than 10 million inhabitants.
