port in the United States will appear in the Newark municipal court on the morning of Jan. 28, a court official told China Daily on Tuesday.

Jiang Haisong, 28, was arrested last Friday evening by US port authorities and released after hours of questioning. Jiang ducked a security barrier in the airport's terminal C on Jan. 3 to bid farewell to his girlfriend after a Transportation Security Administration (TSA) guard stepped away from his post momentarily.

The three terminals at the airport were subsequently shut down for six hours after a bystander who witnessed the incidence notified TSA officials. The shutdown reportedly caused numerous flights delays in and out of Newark, stranding thousands of passengers.

Jiang, a molecular biosciences student who is set to graduate in May, had contacted the Chinese consulate in New York on Monday by phone, said Wang Bangfu, the consul for overseas Chinese affairs at the consulate. Wang told China Daily on Tuesday that the consulate is providing consular protection and assistance to Jiang after identifying him as a Chinese national. These include providing a list of lawyers, which Jiang is selecting for his case. Wang would not reveal more details because Jiang had requested for the content of their conversation to be kept private. But Wang said the consulate has been keeping a close eye on the development. Wang did not comment further on the case until final investigation results were out, implying that the consulate will work to ensure Jiang gets a fair trial and his legal rights are fully protected.

Under the charge of defiant trespassing brought by the Port Authority of New York and New Jersey, Jiang faces a 30-day imprisonment and a fine of $ 500. But New Jersey Senator Frank Lautenberg had earlier pushed for harsh punishment, threatening to lobby for severe federal criminal charges instead of a misdemeanor. Lautenberg also earlier mentioned visa revocation and deportation, but has since toned down his comments on the case in the last few days.

The incidence has triggered strong reaction among people both in the US and China. A number of these have accused Jiang of a "stupid" blunder. Others have hailed him as a kind of hero for exposing a glaring airport security loophole. While more people on the Chinese mainland expressed their disappointment at Jiang for bringing disgrace to the Chinese community, his American neighbors and fellow colleagues at Rutgers University showed more understanding and described him in much nicer words.

e powered by batteries or solar panels.

While trekking in Nepal in 1997, Dave Irvine-Halliday was struck by the plight of rural villagers having to rely on smelly, dim and dangerous kerosene lanterns to light their homes. Hoping to make a difference, Dr Irvine-Halliday, a professor of electrical engineering at the University of Calgary in Canada, founded the Light Up The World Foundation, The non-profit organisation has since helped to distribute low-power, white light-emitting diodes (LEDs), at low cost or free, to thousands of people around the globe.

About 1.6 billion people worldwide are without access to electricity and have to rely on fuel- based sources for lighting. But burning fuel is not only extremely expensive—$40 billion is spent on off-the-grid lighting in developing countries a year—it is also highly inefficient and contributes to indoor air pollution and the emission of greenhouse gases. If people switched from using fuel-based lamps to solar-powered LEDs, carbon-dioxide emissions could be reduced by up to 190m tonnes per year, reckons Evan Mills, a staff scientist at America's Lawrence Berkeley National Laboratory. That is equivalent to one-third of Britain's annual carbon-dioxide emissions.

LEDs are an ideal off-the-grid light source because they need so little power. They can be run on AA batteries, or batteries recharged using small solar arrays. Compared with kerosene lanterns, LEDs can deliver up to 100 times more useful light to a task, besides being extremely long-lasting. All this adds up to a life-changing impact for the lamps' owners, ranging from increased work productivity, more time to study at night and reduced health problems and fire hazards.

Several firms are getting ready to tap into this underserved market. Cosmos Ignite Innovations, a spin-out from Stanford University that is now based in New Delhi, India, has developed the MightyLight, a solar-powered LED-based lamp that is waterproof, portable and runs for up to 12 hours. So far, Cosmos has sold nearly 5,000 of its $50 lamps to various charities.

Another company, Better Energy Systems of Berkeley, California, is testing LED add-ons that might work well with its Solio, a portable solar array that can also be used to charge mobile phones and other devices.

The International Finance Corporation (IFC), the private-sector investment arm of the World Bank, recently secured $ 5.4m in financing for "Lighting the Bottom of the Pyramid", a four-year initiative that will engage lighting manufacturers with pilot projects in Kenya and Ghana.

One task is to make LEDs affordable, says Dr Mills, who is a consultant on the IFC project. Households in rural Kenya, for example, spend an average of $7 a month on kerosene for lighting. Although the cost of a solar-powered LED lamp over its lifetime is much less than the cumulative cost of fuel, many people cannot afford the initial $25 to $50 outlay for such a lamp. If that hitch could be ironed out—via microfinance, perhaps—the payoff could be bright.

What are LEDs? Why are they an ideal light source?

世界杯会如何影响世界经济?各国球迷们享用四年一度的足球大餐时，可能无暇考虑这等严肃的问题，但冷静的经济学家们却已经研究出了新成果。像奥运会一样，世界杯作为一种商业赛事，对东道主而言，意味着财源滚滚的“金鸡”。有专家预测，今年世界杯，德国将至少获得 200亿美元的直接经济效益。所以，荷兰Hypercube咨询公司干脆提议，国际足联将目前四年一度的世界杯赛的频率加快一倍，变成两年一度的赛事。
