It's not often that one can report breakthroughs in fundamental electronic devices, such as resistors or inductors. In fact, the best thing that happened to many inductors is they have been replaced by active circuitry – used, among other places, in active crossovers and other filters – that behave more like theoretically ideal inductors than the real things. But a research report published in NanoLetters is a stunning revelation of what can happen to capacitors when they are infused with a dose of nanotechnology. The title almost says everything: Graphene-Based Supercapacitor with an Ultrahigh Energy Density. Authors Chenguang Liu, Zhenning Yu, David Neff, Aruna Zhamu, and Bor Z. Jang, variously from Nanotek Instruments Inc., Angstron Materials Inc., and the Dalian University of Technology in the People's Republic of China, are merely stating the truth when they claim at the top of the supporting-information file that their research results “are of great scientific and technological significance.”Take a fixed speed diesel, with electric drive and these batteries in between and regenerative breaking. That combo will break some Gallons per Mile records.
