Ingenieros zamoranos crean una red profesional para luchar contra la crisis: Alrededor de 170 ingenieros zamoranos que celebran este año los 20 años de su promoción se han unido en torno a una red profesional que busca apoyarse en sus antiguos compañeros de clase para luchar contra la crisis.

«En tiempos de crisis, los pedidos para los amigos». Con esta máxima, alrededor de 170 ingenieros zamoranos que celebran este año los 20 años de su promoción se han unido en torno a una red profesional que busca apoyarse en sus antiguos compañeros de clase para luchar contra la crisis, informa La opinión de Zamora.

NASA Seeks Student Experiments For 2013 High-Altitude Scientific Balloon Flight

NASA Seeks Student Experiments For 2013 High-Altitude Scientific Balloon Flight: Application Deadline Is December 14 NASA is accepting applications from graduate and undergraduate university students to fly experiments to the edge of space on a scientific balloon next year. The balloon competition is a joint project between NASA and the Louisiana Space Consortium (LaSPACE) in Baton Rouge. The agency is targeting fall 2013 for the next flight opportunity for the High Altitude Student Platform (HASP).

NASA Turns to 3D Printing for Self-Building Spacecraft (via @Intercrastina )



Spacecraft could build themselves or huge space telescopes someday by scavenging materials from space junk or asteroids. That wild vision stems from a modest proposal to use 3D printing technology aboard a tiny satellite to create a much larger structure in space.

The "SpiderFab" project received $100,000 from NASA's Innovative Advanced Concepts program to hammer out a design and figure out whether spacecraft self-construction makes business sense. Practical planning and additional funding could lead to the launch of a 3D-printing test mission within several years.





Currently, launching mass of space systems into space requires high engineering cost - you need to make sure all physically large components to be designed to stow for launch and then reliably deploy on orbit. And, to ensure all things fit inside the rocket there's a limit on sizes of parts.

Tethers Unlimited is going to develop a process for automated on-orbit construction of very large structures and multifunctional components.

This process is called 'SpiderFab' which uses automated processes and fused-deposition modeling to manufacture "very large, very high-strength-per-mass, lattice-like structures combining both compressive and tensile elements. "

LiquidPiston unveils 40-bhp X2 rotary engine with 75 percent thermal efficiency

LiquidPiston unveils 40-bhp X2 rotary engine with 75 percent thermal efficiency:
The LiquidPiston X2 rotary engine boasts a thermal efficiency of 75 percent
The internal combustion engine (ICE) has had a remarkably successful century and a half. Unfortunately, it’s notoriously inefficient, wasting anywhere from 30 to 99 percent of the energy it produces and spews unburned fuel into the air. Last week, Gizmag interviewed Dr. Alexander Shkolnik, President and CEO of LiquidPiston, Inc. about its LiquidPiston X2 - a 40-bhp rotary engine that burns a variety of fuels and requires no valves, cooling systems, radiators or mufflers, yet promises a thermodynamic efficiency of 75 percent...
