Speedy lithium ion batteries, the power source for consumer electronics and electric vehicles, are making inroads into the renewable energy business.
A123 Systems today announced that a Hawaiian wind project developer will use its batteries to firm up power delivery into the grid. The Auwahi Wind project, which has a generating capacity of 21 megawatts, will be buttressed by a giant battery bank able to deliver 11 megawatts of power.
It's the second time this year that A123 Systems' storage systems, built around shipping container-size battery banks, were chosen to be co-located with a wind farm. The Laurel Mountain … Read more
Termites--those pesky insects that you fear might invade and destroy your home--may actually be responsible for the new wave of eco-friendly batteries, if Sony has anything to do with it.
At the Eco-Products 2011 exhibition in Tokyo, Sony showed off a bio-battery prototype that gets its power from shredded paper. In the demo, pieces of paper and cardboard were dropped into a water mixture to magically turn on a small fan. Instead of magic though, the Japanese electronics company took a lesson from nature. … Read more

Apple's second beta of iOS 5.1 launched yesterday with several new fixes and features, but no clue yet as to whether it's squashed the battery drain bug.
Available for registered developers, iOS 5.1 beta 2 addresses a variety of issues, according to Boy Genius Report. Included in the mix are a fix for app icons that had trouble using Game Center and a remedy to address freezes when using the shake-to-shuffle feature to bounce around different songs.
What's the most important measure of any laptop? Some might say the processor speed, or the size and weight, but at the end of the day, it's got to be battery life.
After all, these are mobile devices, designed to be used in coffee shops, airport lounges, and college libraries (even big laptops get carted around occasionally), so being able to spend the maximum amount of time possible away from a wall outlet is important.

These are the people for whom gift cards were created.
Ah, but it doesn't have to be that way. With a minimum of fuss, you can get something unusual for that precious snowflake in your life without having to leave the house. Here, in no particular order, are five Crave-worthy ideas that don't involve your online shopping history being inexorably linked to movies with titles like "Blood Freak" or "The Incredibly Strange Creatures Who Stopped Living and Became Mixed-Up Zombies." … Read more
