Carbon In Nano Form Becomes Graphene For Ultracapacitors
September 19, 2008 | Leave a Comment
Carbon laid out in a one-atom thick layer making a structure called “graphene” is being lab tested as an ultracapacitor by mechanical engineering professor Rod Ruoff at the University of Texas at Austin. Ruoff says, “Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well [...]

A Look A Lithium Accumulators
August 19, 2008 | Leave a Comment
Many of us are familiar with accumulators in gas and hydraulic systems as a vessel that stores a volume usually with an internal diaphragm that has a spring force by a compressed gas. The result is a cell that can buffer the system gases or fluids smoothing pressure spikes.
As a practical point though, a lithium [...]

Storing The Power Of The Wind
June 20, 2008 | 1 Comment
The wind blows at its own time and not necessarily when people need the power from the turbine. That makes energy storage for wind power production an important field. Wind turbines are going up at incredible rates worldwide and offer another problem besides the storage issue – the intermittentcy in very widely disbursed wind farms [...]
