Sandia testing method yields pathway to better, longer-lasting solid-state batteries

Green Car Congress

This illustration shows how a team at Sandia National Laboratories used Kelvin probe force microscopy to locate places where electron flows get stuck, potentially leading to engineering longer-lasting, more efficient batteries. The second thing was to figure out how we can engineer the interfaces to make them less impeding.

New machine learning method accurately predicts battery state of health

Green Car Congress

Using segments of charge voltage and current curves, the pipeline engineers 30 features, performs automatic feature selection and calibrates the algorithms. We first understand battery degradation through collaborations with the CALCE group at the University of Maryland, where in-house degradation testing of batteries was carried out.

U. Maryland and Redox Power partnering to commercialize low-temperature solid oxide fuel cells for distributed generation and transportation

Green Car Congress

University of Maryland researchers have partnered with Redox Power Systems LLC to commercialize low-temperature solid oxide fuel cell (LT-SOFC) technology for distributed generation—and ultimately transportation—applications at about one-tenth the cost and one-tenth the size of current commercial fuel cell systems.

ARPA-E announces $98M in funding for 40 OPEN projects; two opposed-piston engines projects receive $10M total

Green Car Congress

OPEN solicitations are an open call to scientists and engineers for transformational technologies across the entire scope of ARPA-E’s energy mission. Pinnacle Engines will electrify its four-stroke, spark-ignited, opposed-piston engine to improve fuel efficiency and reduce its cost.

Inside the Universe Machine: The Webb Space Telescope’s Chilly Sun Shield

Cars That Think

How then did the engineers and designers of this massive telescope ever make it possible to cool the telescope down enough—all at a remove of nearly four times the earth-moon distance—to possibly do its job? The elongated shape, engineers found, would be the most efficient way to keep the Webb’s optics out of the sun.
