A powerful typhoon hit Hong Kong and the southern China coast on Monday, killing at least 20 people on the mainland, crippling power lines and causing flooding and gale force winds. Typhoon Usagi, the strongest storm to hit the Western Pacific this year, began pounding the Asian financial center late on Sunday. More than 370 flights were canceled. The No. 8 signal warning remained in force early on Monday, with financial markets closed for at least part of the morning. The weather observatory said the storm had weakened from "super" typhoon status and that it would consider lowering the warning signal before 10 a.m. (0200 GMT) China's National Meteorological Centre issued its highest alert, with more than 80,000 people moved to safety in Fujian province and authorities deploying at least 50,000 disaster-relief workers, state Xinhua news agency reported. At least 20 people were killed on China's southern coast, television reports said, including 13 in Shanwei in the eastern fringes … [Read more...] about Powerful typhoon kills 20 in southern China, swipes Hong Kong
HCM City's Department of Science and Technology and the Energy Saving Centre have launched the "Solar Car Racing 2011" competition in a bid to explore the potential of green transport. The competition, being held in Viet Nam for the first time, has attracted the participation of 45 teams from nine universities and 23 enterprises from Bac Ninh, Da Nang, Nha Trang, Binh Duong, Dong Nai and HCM City. Each team was provided with a solar battery made domestically to power their prototype car, which must be able to travel between 16kph and 40kph. The competition, which will have three rounds, will start on October 24. The final will take place on December 12. Huynh Kim Tuoc, director of HCM City's Energy Conservation Centre, said he hoped the competition would raise awareness about how solar energy can reduce the nation's carbon footprint. "The research and development of renewable energies would also be promoted," Tuoc said. Hoang Cuong, director of An Lac Company, which is … [Read more...] about Solar-powered cars to explore potential of ‘green’ transport
A noted oceanographer says Vietnam is overlooking an abundant energy resource, the waves of the East Sea. Dr. Nguyen Tac An is former dean of the Vietnam Institute of Oceanography in Nha Trang and current Chairman of Vietnam's branch of the Intergovernmental Oceanographic Commission (IOC). An talked with the HCM City newspaper Thanh Nien about the potential for wave power development in Vietnam. In 1973, An says, research began on wave power in some developed countries like the US, Portugal and France. In 2003, Portugal deployed the first 30 MW wave power plant. The production cost of wave power is equivalent to wind power, that is, about 10 US cents per kilowatt-hour. What is wave power? Wave power is the capture of wave energy to do useful work, for example, electricity generation or water desalination. An easy way to capture the already abundant energy in the ocean is through a simple air chamber. As the waves rise and fall in the chamber, they force air through the … [Read more...] about Energy challenges: Why not wave power too?
A raging California wildfire burning on the northern tip of the storied Yosemite National Park now threatens San Francisco's water and electricity supply. LOS ANGELES: A raging California wildfire burning on the northern tip of the storied Yosemite National Park now threatens San Francisco's water and electricity supply, officials said Sunday. The Rim Fire has charred through 133,980 acres (54,220 hectares), growing nearly 8,400 acres overnight, according to InciWeb, the online Incident Information System that monitors fires in the western United States. The fire was just seven per cent contained, InciWeb said, adding that it "remained fairly active overnight in most all divisions," and exhibited "rapid rates of spread, torching and spotting" on its eastern edge. More than 2,800 firefighters, supported by helicopters and air tankers, are struggling to contain the blaze, which started on August 17 from still unknown causes. Extremely dry conditions due to a prolonged drought, … [Read more...] about California fire threatens San Francisco water and power
Following the delay of 12 flights due to the late recovery of the check-in system of Vietnam Airlines (VNA) after a power loss, Tan Son Nhat airport authorities have requested the carrier to take measures to prevent similar cases in the future. The request was made by the airport authorities after the delay that affected about 1,000 passengers on Sunday, said Dang Tuan Tu, director of the airport. Tuan pointed out that on February 10, 2013, which is the second day of the Lunar New Year festival, a similar case happened to the carrier and lasted for a relatively long period. As previously reported, the latest power outage occurred at about 1:10 pm June 16 and the airport immediately began using its standby power source, but the check-in system of Vietnam Airlines did not come back online. As a result, airline employees had to carry out check-in by hand, leading to delays for 12 flights, both local and international, Giang said. Le Viet Cuong, deputy director of the airport … [Read more...] about Airline asked to prevent power-related delays
