Estonia launches national electric car charging network
Thursday, 21 February 2013
Estonia's reputation as one of the most wired-up countries in Europe has been boosted further with the opening of what is being billed as the world's first nationwide electric car charging network. Business jet will have sturdier batteries than Boeing 787
Tuesday, 19 February 2013
A lithium-ion battery for Cessna Citation business jets is designed to contain an overcharge explosion within an armored casing — unlike the Boeing 787 batteries that led to the plane’s grounding. While Boeing and federal safety regulators ponder why flames and hot electrolytes shot out of lithium-ion batteries on the company’s flagship 787, prompting a grounding order that’s now in its third week, business jet-maker Cessna is testing a new design for such batteries — one that can contain a worst-case explosion within an armored box.

Late Thursday, the FAA gave Boeing the go-ahead to conduct limited test flights of the grounded 787 Dreamliner. On that same day, a Boeing flew an empty 787 from Texas back to its factory in Washington state. The planes were grounded three weeks ago after batteries overheated twice; one of the batteries caught fire.
Federal investigators revealed the fire aboard the Dreamliner in Boston last month began with a short circuit in one of the lithium ion battery's eight cells. That caused a dangerous condition known as "thermal runaway," where a short spreads to other cells in an uncontrolled chemical chain reaction. The fire topped 500 degrees Fahrenheit.
