Algorithm could help reduce power grid faults

Algorithm could help reduce power grid faults
The power grid is aging, overburdened and seeing more faults than ever, according to many. Any of those breaks could easily lead to prolonged power outages or even equipment damage. Binghamton University researchers have proved that the Singular Spectrum Analysis (SSA) algorithm may be the best tool to help authorities remotely detect and locate power grid faults.

Tiny probe could improve batteries and fuel cells

A team of American and Chinese researchers has developed a new tool that could aid in the quest for better batteries and fuel cells. Although battery technology has come a long way since Alessandro Volta first stacked metal discs in a "voltaic pile" to generate electricity, major improvements are still needed to meet the energy challenges of the future, such as powering electric cars and storing renewable energy cheaply and efficiently.

Thermal bag to counter fire risk from Li-ion batteries

Thermal bag to counter fire risk from Li-ion batteries
Morgan Advanced Materials has introduced to the aviation market a novel means of tackling the risk posed by overheating lithium-ion batteries, following an extensive period of testing in conjunction with Germanwings, part of the Lufthansa Group. The FireMaster battery bag, which measures 500x500mm, comprises two of Morgan’s specialist thermal materials to create a sealable, water-resistant compartment capable of containing the heat spread in the event of a primary-lithium or lithium-ion battery fire.

Rays provide power for an electric generator

Rays provide power for an electric generator
Scientists from the RIKEN Quantitative Biology Center in Japan removed the electric organ from a torpedo and chemically stimulated the organ by injecting a solution of the neurotransmitter acetylcholine though a syringe. They were able to achieve more than a minute of continuous current, with a peak voltage of 91 mV and 0.25 mA of current. By increasing the number of syringes, they achieved a peak voltage of 1.5 V and a current of 0.64mA.
