Not for green technology, but for country

August 3, 2012 3:16 pm | by Clara Ennist, Editorial Intern | Blogs | Comments

When building better weapons, a focus on green technology is untenable; rather, weapons need to be accurate, cost effective, and pose the least harm to US soldiers. How “green” a weapon is can be an unintended, positive consequence. Enter the Navy’s Electromagnetic Rail Gun (EMRG) with guided munitions.

Here are five other key points:

Within reach: Drexel engineers to add arms and hands to unmanned aerial vehicles

August 2, 2012 2:13 pm | by Eurekalert! | News | Comments

PHILADELPHIA - Unmanned aerial vehicles (UAVs), such as those used by the military for surveillance and reconnaissance, could be getting a hand –and an arm– from engineers at Drexel University as part of a National Science Foundation grant to investigate adding dexterous limbs to the aircrafts. The project, whose subject harkens to the hovering android iconography of sci-fi movies, could be a step toward the use of UAVs for emergency response and search and rescue scenarios.

Anti-aging elixir for solar cells

August 2, 2012 2:12 pm | by Eurekalert! | News | Comments

Sometimes it's just a couple of cents that decide the success or failure of a technology. As long as solar power, for instance, is still more expensive than energy extracted from fossil fuels, photovoltaics will not be competitive on the broad open market. "Power generation from solar energy continues to be reliant on public subsidies – this is no different in the USA than in Germany," explains Christian Hoepfner, Scientific Director of the Fraunhofer Center for Sustainable Energy Systems CSE in Cambridge, Massachusetts, USA. "If we want renewable energy to penetrate the global market over the long term, then we must ensure it gets cheaper."
