Cerebral: A Brainier Kind of Battery

Dean Sigler Announcements, Batteries, Sustainable Aviation Leave a Comment

Cerebral, the brainchild of Dr. Lynden Archer—Dean of the School of Engineering at Cornell University, is as the name implies, a smart approach to battery development.  Claimed to be three times more efficient than lithium, much safer with no fire risk, and ten times faster charging, the battery is made of recycled aluminum and graphene.  In fact, materials for the battery come from United States-based waste streams.  Low-grade domestic carbon waste, for example, goes through a “Graphitizer,” a machine “created at the University of California, Riverside’s Mechanical Engineering Department and exclusively optioned by Cerebral Energy.” (Editor’s Note: Forgive the lack of product-related images or videos here.  Your editor could not find an illustration of a graphitizer, for instance, or any research photos or graphs related to this relatively new research area.  We will share any such images as soon as they are available.) The Uncertain Graphite Supply Line This is an important development, since the U. S. imports most of …

100 Percent Efficiency? Great! and So What?

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

A particularly brilliant and demanding manager for whom your editor used to work had a “SO WHAT?” stamp with which he would critique our technical papers and proposals.  His point in defacing our papers was not to be snide, but to force us to defend why we included certain facts – interesting though they may be in themselves. Two different and equally brilliant discoveries by University of Cambridge and University of California, Riverside researchers bring the “so what?” stamp to mind.  Even with their breakthroughs, approaching 100-percent efficient solar cells in the first instance, solar cells may not yet be a perfect fit for aircraft propulsion. Each square foot of the earth’s surface receives about 15 Watts of solar energy during a bright day.  100 square feet of solar cells (about what we could expect for an average-size wing on an average light plane) would see 1.5 kilowatts hitting that surface – not enough to sustain flight on anything but …
