Glass is a dielectric material, which means electrons don’t pass easily between two of its surfaces. This property makes glass (and other dielectrics) suited for capacitor applications, where its  two […]

A Dayton, Ohio-based company, Nanotek Instruments, has recently revealed their vision about making ultracapacitors, for the moment only used in hybrid buses, suited for electric cars and how to replace the classic batteries.

Utilities producing power from wind or solar, for example, have to develop ways of storing the energy for the periods when there isn't such a great demand on the grid, and the produced power is higher than the consumed.
