Passengers will no longer be able to pack loose lithium batteries in checked luggage beginning January 1, 2008 as new federal safety rules take effect. The new regulation, designed to reduce the risk of lithium battery fires, will continue to allow lithium batteries in checked baggage if they are installed in electronic devices, or in carry-on baggage if stored in plastic bags.

Common consumer electronics such as travel cameras, cell phones, and most laptop computers are still allowed in carry-on and checked luggage.  However, the rule limits individuals to bringing only two extended-life spare rechargeable lithium batteries, such as laptop and professional audio/video/camera equipment lithium batteries in carry-on baggage

The following quantity limits apply to both your spare and installed batteries. The limits are expressed in grams of “equivalent lithium content.” 8 grams of equivalent lithium content is approximately 100 watt-hours. 25 grams is approximately 300 watt-hours:

• Under the new rules, you can bring batteries with up to 8-gram equivalent lithium content. All lithium ion batteries in cell phones are below 8 gram equivalent lithium content. Nearly all laptop computers also are below this quantity threshold.

• You can also bring up to two spare batteries with an aggregate equivalent lithium content of up to 25 grams, in addition to any batteries that fall below the 8-gram threshold. Examples of two types of lithium ion batteries with equivalent lithium content over 8 grams but below 25 are shown below.
• For a lithium metal battery, whether installed in a device or carried as a spare, the limit on lithium content is 2 grams of lithium metal per battery.
• Almost all consumer-type lithium metal batteries are below 2 grams of lithium metal. But if you are unsure, contact the manufacturer!

Indeed this regulation will first be applicable on US registered aircrafts but as usual we may see this new regulation applicable on all International flights. 

Usually all electrical devices, including batteries, are subject to safety certification so either their are considered to be safe or manufacturer has to review quality and safety of its products. 

I really wonder on which basis these new rules are made from. Did anyone saw any incident statistics, reports etc.. (apart Sony made laptop batteries) or is it just one additional constraints air travel passengers will have to deal with.

After lighters and matches in 06, liquids in 07, 08 will add batteries to the restriction list.

All details are here as well as the complete list of items with air travel restrictions

As previously announced on this site, Adobe released earlier this week, Lightroom 1.3 as well as Camera Raw 4.3.

At the same time Adobe Labs offers a public prerelease of its Software Development Kit (SDK) Lightroom 1.3 export. This kit allow developers to enable communication with Lightroom 1.3 and 3rd party tools, web sites and devices. More plugins will certainly available soon on Lightroom Exchange site.

Adobe Photoshop Lightroom 1.3 Export SDK comes with two very useful plugins: 

• FTP Export
• Flickr Upload.

Once dowloaded and uncompressed, plugin modules have to be installed on your computer on locations where Lightroom can find and load them.

• Windows XP: ..\Documents and Users\username\Application Data\Adobe\Lightroom\Modules
• Mac OS: ~/Library/Application Support/Adobe/Lightroom/Modules
• Windows Vista:..\Users\username\AppData\Roaming\Adobe\Lightroom\Modules

I just quickly tried the Flickr upload module and found it easy to use and indeed very convenient as it avoids to export files on a local folder and then upload them using Flickr Uploader page or tools.

Something tells me that these plugins will become very popular  

China Mobile, the World largest mobile phone service provider with its 350 millions customers (mainly in China!) has completed the installation and testing of their 3 mobile phone base stations installed on Mt-Everest slopes.

The 3 solar-powered stations installed respectively at 5200, 5820 and 6500 meters above sea level, were transported by porters and yaks and built in a harsh environment where oxygen level is only 38 percent of what it would be on ground. They will make possible for climbers and those who will be 2008 Summer Olympics torch relay route to establish and receive calls along the entire Mount Everest climbing route, including its 8'848m. peak.

After the completion of these ultimate test, China mobile workers immediately started to pack all equipments away for the winter. The station will be reinstalled next summer before 2008 Beijing Olympics.
