A “digital quantum battery” concept proposed by a physicist at the University of Illinois at Urbana-Champaign could provide orders-of- magnitude-greater energy storage capacity.
The concept calls for billions of nanoscale capacitors and would rely on quantum effects to suppress arcing, which wastes stored power.
The digital part of the concept derives from the fact that each nanovacuum tube would be individually addressable. Because of this, the devices could… read more
