French National Engineering Awards 2015: Wind-it wins Industry and Technology prize

Wednesday 14 October 2015 – The Grand Prix National de l’Ingénierie (French National Engineering Awards) is to award its Industry and Technology prize to the Wind-it project, an innovative renewable energy generation solution developed since 2007 by Elioth. The principle is to install one or several vertical axis wind turbines (VAWT) onto the structure of high metal pylons specifically designed to accommodate them. This innovation is the tangible convergence point of communication networks and renewable energy. Top marks for its original technical architecture and its application potential! More here and on the dedicated blog here.


Aubervilliers footbridge

A new footbridge now crosses the “periphérique” at the Porte d’Aubervilliers in Paris! On the night of May 14 to 15, 2015, The infamous Parisien ringroad ground to a halt for a few hours while a 700 ton crane was positioned to complete the installation of the central span of the ZAC Claude Bernard bridge. At midnight, this 80metre long, 100 ton section was delicately raised into the air. A nail-biting 20 minutes later and the structure was in place. A dedicated site team took over and worked through the night to complete the assembly to the abutments.

Success! At daybreak, the cranes were folded and footbridge had found his place.

A little patience will be required however before you can tread its planks…
