Real-Time Space Observations can now Keep Watch Over 'Super Emitter' Power Plants

Real-Time Space Observations can now Keep Watch Over 'Super Emitter' Power Plants

­Countries signed up to the 2015 Paris Agreement have committed themselves to keep the rise in average global temperature ‘well below’ 2 °C. Every five years, they are to issue so-called ‘nationally determined contributions’ (NDCs), describing their actions to reduce greenhouse gas (GHG) emissions an

U.S. Army Chooses Resilient Lead Batteries

Dr. Matt Raiford, CBI project manager

­The U.S. Army has chosen advanced lead battery energy storage systems to enhance its operational effectiveness in disaster zones and in combat. A project led by Paragon Solutions, Inc., and the Consortium for Battery Innovation (CBI) is providing a new set of systems that can provide power for critical military operations anywhere in the world. Paragon, a woman-owned engineering firm, and a member of the Consortium for Energy, Environment, and Demilitarization (CEED), partnered with CBI, a global lead battery research hub, to develop the winning proposal in response to a request issued to CEED members by the Consortium Management Group (CMG).

Non-Illuminated Switch with Colored Ring Indication

Non-Illuminated Switch with Colored Ring Indication

­SCHURTER extends its Metal Design Line series MSM to include a version with a non-illuminated indicator. A colored ring is used instead of an illuminated ring, which lowers the cost of the switch and eliminates the cost associated with wiring an external power source to drive LEDs. Consistent with SCHURTER qu

Solving Weight and Supply Chain Issues with Military Batteries

Solving Weight and Supply Chain Issues with Military Batteries

­50 years ago, military personnel had few electronic devices at their disposal, so did not need to acquire or carry many batteries. In the years since, as the number of devices grew, so did the number of batteries needed to power them, which started to impact the supply chain and the weight a soldier must carry. He
