3D-Printed Wind Turbine Blades Could Bring ‘Sci-Fi’ Level of Performance
(3Ders.org) The rapid advance of 3D printing technology means that hybrid-material wind turbine blades complete with metal mesh inserts are no longer the stuff of imagination. These energy savers with “sci-fi-level” performance could become reality in as soon as two years. Philip Totaro of Totaro & Associates, “The greatest challenge for wind turbine blade structural and manufacturing engineers is to implement the idealized performance and noise mitigated designs of aerodynamics engineers,” explains Totaro. “Limitations of previous generations of manufacturing technology and the reliance on lower cost materials have limited the type of spar/shear web structures which could be utilized.” But 3D printing could be about to change all that, Totaro says.

Samsung’s New Electric Car Batteries Boost Range to 600 Kilometers
At the Frankfurt Motor Show (IAA Cars 2017) in Germany earlier this week, Samsung SDI — the battery-focused division of Samsung — unveiled a new multi-functional battery pack capable of increasing the current range of electric vehicles. As explained by the Korean company, the battery enables cars to go between 600–700 kilometers (372−4343 miles), provided the right number of modules are installed.
“Its users can change the number of modules as they want as if they place books on a shelf,” says Samsung. “For example, if 20 modules are installed in a premium car, it can go 600 to 700 kilometers. If 10 to 12 modules are mounted on a regular sedan, it can run up to 300 kilometers. This pack is expected to catch the eyes of automakers, because they can design a car whose mileage may vary depending on how many modules of a single pack are installed.”
Electrek explains that automakers like Nissan and GM have been using prismatic cells in their battery packs. Samsung SDI began developing new “2170” cylindrical cells earlier this year, following the footsteps of Tesla, which was the first to do so with their “2170” battery cell.

A Tunisian Energy Company Wants to Pipe Electricity from the Sahara to Europe
The company TuNur aims to produce solar energy cheaply in the Sahara desert and distribute it to Europe. However, there are lingering questions about whether the company behind the project can actually pull it off.
Energy company TuNur is seeking approval from the Tunisian government for a 4.5GW solar park situated in the Sahara desert. If it’s given the green light, the project would distribute electricity to Malta, Italy, and France via submarine cables.
