(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.
The sun fired off yet another powerful solar flare yesterday (Sept. 10), its seventh in seven days.
The flare, which peaked at 12:06 EDT (1606 GMT), covered North and South America in high-energy light. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC) released a statement that warned of strong, high-frequency radio blackouts and navigation-system disruption, potentially lasting up to an hour.
At the Barcelona Supercomputer Centre on Wednesday (Sept. 6), 16 partners gathered to launch the EuroEXA project, which invests €20 million over three-and-a-half years into exascale-focused research and development.
Led by the Horizon 2020 program, EuroEXA picks up the banner of a triad of partner projects — ExaNeSt, EcoScale and ExaNoDe — building on their work to develop a complete HPC system based on ARM Cortex processors and Xilinx Ultrascale FPGAs. The goal is to deploy an energy-efficient petaflops system by 2020 and lay a path to achieve exascale capability in the 2022–23 timeframe.
All told, the European Commission is planning a €50 million investment for the EuroEXA group of projects, spanning “research, innovation and action across applications, system software, hardware, networking, storage, liquid cooling and data centre technologies.”
How to “Get Better”: Approaches to LGBTQ-relevant Video Games Presented by: Robert Yang
Given today’s attempts at LGBTQ outreach and advocacy, e.g. the “It Gets Better” campaign, it makes sense to explore more queer-relevant content through engaging and thoughtful video game design. So how do we get LGBTQ content “right”? For that matter, what does “LGBTQ content” even entail? What are the ways that video games imply notions of gender and sexuality through their graphics, sounds, interfaces, and mechanics? Listeners will take away design techniques to integrate socially relevant content into games, ethical concerns in doing so, and a very brief overview of LGBTQ issues.
Crafting Science Learning Games that People Will Play — Two Voices, One Goal. Presented by: Jodi Asbell-Clarke, Scott Kirk
Jodi and Scott will tell a tale of woe, hope, and compassion about co-developing educational games. With a dual mission, entertainment and learning, the games developed by EdGE and GameGurus are walking the fine line of research and commercial development. The vastly different perspectives of an educational researcher and a commercial game designer present challenges, tension, grief, and ultimately opportunities for new types of games that can make a difference. Jodi will explain the need for grounding the game in solid pedagogical design so that research measurements will be effective and convincing to funders and educational systems. Scott tries to fit those constraints into the world of development timelines, budgets, and profit margins. It all works when both teams have the creative spark, worthy goals, and a lot of energy.

The new plasma has been developed by researchers from MIT. Unlike most plasmas, which are made up of two ion species, the new plasma is made up of three ion species.
Scroll down for the [VIDEO] Some information and frequently asked questions about Advanced Denial System are :
Q1. Why do we need this technology? A1.The Active Denial System is needed because it’s the first non-lethal, directed-energy, counter-personnel system with an extended range greater than currently fielded non-lethal weapons. Most counter-personnel non-lethal weapons use kinetic energy (rubber rounds, bean bags, etc.). A kinetic-based system has a higher risk of human injury, and its effectiveness varies in relation to the size, age and gender of the target. The Active Denial System, however, is consistently effective regardless of size, age and gender and has a range greater than small-arms range. The Active Denial System will provide military personnel with a non-lethal weapon that has the same effect on all human targets.
Q2. What type of Department of Defense missions will the Active Denial System support? A2. The Active Denial System will support a full spectrum of operations ranging from non-lethal methods of crowd control, crowd dispersal, convoy and patrol protection, checkpoint security, perimeter security, area denial, and port protection, as well as other defensive and offensive operations from both fixed-site or mobile platforms. The Active Denial System is an advanced, long-range non-lethal, directed energy, counter-personnel capability that projects a man-sized (1.5 m) beam of millimeter waves (not microwaves) at a range up to 1,000 meters. It will have the same compelling non-lethal effect on all human targets, regardless of size, age and gender.
