We all know about the most famous Chinese mode of transportation, the bicycle. Indeed with the situation is changing and the bicycle leaves more and more its place to cars & motorbikes. 

I arrived 2 days ago in Kunming, the capital of the Yunnan province. The city is growing and its 6 millions inhabitants add 200 cars on the road every single day. However in a city where a liter of petrol costs 0.50 USD and the monthly salary is less than 100 USD I wonder what is the average yearly mileage of this multitude of vehicle.

What surprised me here is that most scooters in town are electric and this idea should inspire Europe. However I have not seen how they recharge them and if the battery can easily be remove and be charged at home. I'll try to have a deeper look in the coming days .

Specifications are the following

Dimension: 1700*555*1170
N weight/ G weight: 115/136KGS
Max speed: <60Km/h
Battery: 48V/38AH Silicone
Motor Power: 1500W
Load capacity: >85Kg
Brake: Disk brak FR, drum brake RR
Mileage for one charge: 80Km

Who said that in China there are no efforts made to reduce carbon emissions ? 

I haven't review in details all news from the CES 2008 that closed its doors on Thursday but it seems the Global Energy problem contributes to have better ideas regarding the way we can power our IT stuff.

One company, Green Plug, has identified a significant contributor to the high cost of battery-powered consumer electronics products, wasted energy and unnecessary toxic waste. A typical home or office has a dozen or more power transformers that convert between 90V and 254V wall power to device-specific DC power. Every adapter is physically unique and therefore is thrown away every time a device is replaced.

Green Plug comes with a better idea.

Creating a standardize power supply which can be used by all Green Plug^TM compliant devices utilize uniform cables and connectors; so, you never have to worry about finding the right adapter for your laptop, DV camera, cell phone or power tool.

Let's hope they will be able to convinced enough partners to have a real impact on the market and we'll have soon all our electronic devices using a single and unique type of power supply.

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.
