Advanced Infrared Camera Maps Methane "Hot Spots"

Methane often appears in the atmosphere at an irregular rate, puzzling researchers challenged with the task of tracking the gas’s sources in the landscape. An advanced infrared camera developed by Linköping University and Stockholm University researchers, in collaboration with the infrared imaging manufacturer Telops, allows users to both film and photograph methane emissions.

A New Generation of Cooling

Energy efficiency is key to the total cost of ownership of enclosure climate control solutions, and electricity consumption is a major element of operating costs. Hybrid technology, developed and patented by Rittal, combines conventional compression cooling, similar to what has been used in traditional air conditioners, with a heat pipe. The heat pipe uses evaporation of a working fluid in an evacuated tube.

40th Anniversary Reader Contest Winners

In the 1960s, the newly formed NASA began issuing single-sheet reports on the commercially significant technologies the agency was developing in the course of R&D being conducted for the space program – a mandate from Congress. In 1976, NASA turned those single-sheet reports into a magazine format called NASA Tech Briefs.

The Fourth Revolution in Manufacturing

The fourth industrial revolution, or Industry 4.0, is all about going digital. But the term – and the basic idea behind it – are not new. First used in 2011 at Hannover Fair in Germany, the term Industry 4.0 originates from a question posed by the German government to its country’s manufacturing industry leaders: What is the next stage of evolution for manufacturing?

Thermal Cameras Reveal Materials’ Secrets

Scientists at the Department of Energy’s Oak Ridge National Laboratory are pioneering the use of infrared cameras to image additive manufacturing processes in hopes of better understanding how processing conditions affect the strength, residual stresses and microstructure of 3D-printed parts.

Researchers Turn Solar Energy into Electrical Power Using Photo-Bioelectrochemical Cells

A new paradigm for the development of photo-bioelectrochemical cells has been reported by researchers from The Hebrew University of Jerusalem, in Israel, and the University of Bochum, in Germany. The design of photo-bioelectrochemical cells based on native photosynthetic reaction is attracting substantial recent interest as a means for the conversion of solar light energy into electrical power.

NASA Engineers Tapped to Build First Integrated-Photonics Modem

A NASA team has been tapped to build a new type of communications modem that will employ an emerging, potentially revolutionary technology that could transform everything from telecommunications, medical imaging, and advanced manufacturing to national defense. The space agency’s first-ever integrated-photonics modem will be tested aboard the International Space Station beginning in 2020 as part of NASA’s multi-year Laser Communications Relay Demonstration, or LCRD.

The cell phone-sized device incorporates optics-based functions, such as lasers, switches, and wires, onto a microchip — much like an integrated circuit found in all electronics hardware. Once aboard the space station, the so-called Integrated LCRD LEO (Low-Earth Orbit) User Modem and Amplifier (ILLUMA) will serve as a low-Earth orbit terminal for NASA’s LCRD, demonstrating yet another capability for high-speed, laser-based communications.

Drone Control: Flying the Crowded Skies

Long before stories of Unmanned Aircraft Systems (UAS), or “drones,” appeared frequently in the news, NASA and the Federal Aviation Administration (FAA) recognized the need to safely manage UAS flying at low altitudes in airspace not currently managed by the FAA. For more than 25 years, NASA has conducted air traffic management system research in partnership with the FAA, providing a variety of computer-based tools that help maintain safety in increasingly crowded skies.

FAA and Drone Control

Since the early 1990s, unmanned aircraft systems (UAS) have operated on a limited basis in the National Airspace System (NAS). Until recently, UAS mainly supported public operations, such as military and border security operations. The list of potential uses is now expanding rapidly to encompass a broad range of other activities, including aerial photography, surveying land and crops, communications and broadcasting, monitoring forest fires and environmental conditions, and protecting critical infrastructures.

CO2 Recovery System Puts Bubbles into Beer

Technology used to capture carbon dioxide in the Martian atmosphere can save brewers money.

Building on work he and his companies did with Johnson Space Center’s In Situ Resource Utilization (ISRU) team, Robert Zubrin has developed and commercialized technologies that could prove revolutionary in their Earth applications, such as a system that could extract millions of barrels of oil from defunct oil wells around the world, and another that can harness all the natural gas currently burned off as waste at many oil drilling rigs.
