Hybrid Cars Expected to Start Mass Production in 2011
Toyota announced on Sunday that it's planning to introduce its Lexus hybrid sedan in Korea for around W200 million (US$1=W937). Hybrid cars are powered by both a gasoline engine and an electric battery. With increased fuel efficiency, the eco-friendly hybrids are currently in the limelight.
The battery is the core technology in the vehicles, and Toyota leads the hybrid market with cars armed with nickel metal hydride (NiMH) batteries. Meanwhile, Korean auto and battery makers boast that they're no longer behind Japan when it comes to battery technology. But are their claims true?
While Japan is focused on developing NiMH batteries, the domestic industry is pouring its effort into lithium-ion (Li-ion) batteries. Currently most batteries used in mobile phones and laptops are now being replaced with Li-ion batteries.
However, according to statistics from the Korean Intellectual Property Office (KIPO) on Monday, between 1999 and 2005, Korean companies applied for less than 200 patents related to Li-ion batteries, about 10 percent of the Li-ion applications filed in Japan. Even worse, there is wide gap between the two nations not only in quantity but also in quality.
In order for Li-ion batteries to be used in cars, what matters most are the battery's safety, structure and material. Safety controls for Li-ion batteries are much higher than for NiMH batters because Li-ion batteries can explode. If a battery exploded in a car, the damage would be much greater than an explosion in a mobile phone or lap top. The patent applications filed in Japan are focused on the safety and structure of Li-ion batteries, but Korean manufacturers are applying for patents for the electrolyte element of the battery, which is relatively easy, the KIPO said. Against this backdrop, it is clear that Korean carmakers and battery researchers need to step up their efforts.
Seoul Ranked Among Most 'Honest' Cities
Seoul Ranked Among Most 'Honest' Cities
Seoul scored high marks in an informal test to measure just how honest people are around the world.
For its annual "Global Courtesy Test", monthly magazine Reader's Digest left 30 mid-priced mobile phones in busy public places. Reporters observed the phones from a distance, called them and waited to see if anyone would answer. Would the finders return the phones?
Not in Kuala Lumpur or Hong Kong. Those cities ranked in the bottom of the survey with just 13 phones of 30 returned in each city.
Seoul did much better with 27 phones returned, ranking it third on the list of 32 cities. Ljubljana in Slovenia ranked first with 29 phones returned and Toronto came in second with 28 phones returned.
Several cities known their citizens' civility ranked lower than expected -- Amsterdam placed 29th with 14 phones returned, Lisbon ranked 28th with 15 phones back, and Sydney and London tied at 21st with 19 phones returned each.
The Seoul test was executed on busy streets in the metropolitan area, including the underground square in 63 Building in the Yeouido financial district. Details of the test will be published in the August issue of Reader's Digest.
A member of the magazine's editorial staff said, "It seems that Seoul citizens have a high level of honesty. Of course, in Seoul where high-end cellphones are common, it could be assumed that people thought the cellphones weren't attractive enough to keep."
The staffer added, "The most important thing is global honesty was found to be higher than expected. We guessed that most phones wouldn't be returned, but the results showed that 654 of 960 phones came back."
