Taking a proactive stance to address environmental concerns, leading engineers from business, academia, and government have united to draft principles to guide their trade.
Nine tenets of Green Engineering (below) were developed during a May 18-22, 2003, multidisciplinary conference entitled “Green Engineering: Defining the Principles” held in Sandestin, Florida.
Attendees from such diverse entities as the White House Office of Science and Technology Policy, NSF, Siemans, and the Zero Waste Alliance defined green engineering as, “the design, commercialization, and use of processes and products, which are feasible and economical while minimizing generation of pollution at the source and risk to human health and the environment.”
There is a duty to inform society of the practice of green engineering.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
