A university yesterday said it had developed energy-saving LED lamps that could cut costs for fishermen who use bright lights on their boats to attract fish.
“LED lamps can help reduce overall fuel consumption on fishing boats by between 15 and 20 percent,” National Cheng Kung University professor Shen Sheng-chih (沈聖智), who helped develop the device, said at a press conference.
The LED lamps use less than 10 percent of the power required by traditional fishing lamps, allowing more energy to be diverted to freezers to ensure catches remain fresh, Shen said.
Many fishermen turn off their freezers to save power while running traditional lamps, he said.
Shen and Fang Ming-chung (方銘川), both professors from the university’s Department of Systems and Naval Mechatronic Engineering, developed the lamp over a five year period with NT$20 million (US$669,000) in funding from the Council of Agriculture.
The lamp was also designed to project patterns of light on the surface of the ocean to attract fish, Shen said, adding that the LED lamp is the first device in the world to be designed with this function.
Shen said the lamp’s unique light patterns entice fish to remain longer in lit areas, adding that the LED lamp would dispel the myth that the brighter the light, the better the catch.
The professor added that the LED lamp is safer for fishermen, who are often exposed to hazardous ultraviolet rays emitted by traditional fishing lamps.
Over the past three years, the LED lamp has been used in test runs on a number of Taiwanese fishing vessels and test results have shown that fuel costs can be cut by about NT$300,000 a year for offshore vessels and by more than NT$2 million per four-month voyage for open-ocean vessels, Shen said.
If all fishing vessels in the country used the LED lamp, fishermen could save a total of between NT$600 million and NT$700 million in fuel costs each year, the study found.
Shen added that the LED lamp can easily be switched on and off, “unlike traditional lamps, which cannot be turned on for up to 20 minutes after being switched off.”
He said that this function allows fishermen to have better control over when they catch fish.
The results of the study have been given to two local manufacturers and Japanese companies have also expressed interest in the technology, as similar lamps in Japan may be 10 times more expensive, Fang said.
WAR FUNDING: A report by UK and Ukrainian defense analysts said that Taiwanese exports of a compound used in gunpowder have been helping Russia propagate its war About 20 percent of nitrocellulose — a compound used in gunpowder — imported into Russia has been sourced from Taiwan, a joint British-Ukrainian investigative report showed. Nitrocellulose is a key component of smokeless gunpowder, and the EU has banned export of the compound to Russia due to its ongoing war of aggression against Ukraine. The report said that nitrocellulose produced in Taiwan makes its way to Russia by passing through other countries such as Turkey. Only one company, T.N.C. Industrial Co (台硝), was named in the report, which also named China and Germany as key sources of the compound for
Individual tourists who arrive in Taiwan from tomorrow are eligible to receive limited-edition lucky bags to mark the Lantern Festival, Tourism Administration officials said yesterday. The Lantern Festival-themed lucky bags each contain a Year of the Dragon red envelope, a mini lantern, a NT$300 coupon for an amusement park ticket and a NT$500 Taiwan PASS coupon, the officials said. To get a lucky bag, visitors must present a passport or residence certificate and proof of their date of entry at a tourism center at either terminal at Taiwan Taoyuan International Airport, Taipei International Airport (Songshan airport) or Kaohsiung International Airport, they said.

FOOD FRACAS: Legislative Speaker Han Kuo-yu called for the premier to deliver the address at 10:27am, but KMT legislators swarmed the podium to block him Chinese Nationalist Party (KMT) lawmakers yesterday temporarily obstructed Premier Chen Chien-jen (陳建仁) from giving what is likely to be his last policy report to the legislature in protest at the Cabinet’s handling of food safety issues. The premier eventually delivered his report after a spat between caucuses about how and when Chen should deliver a special report on food safety. The KMT wanted the premier to make the special report yesterday, while the Taiwan People’s Party (TPP) said that the legislature should hold an internal meeting on the issue today and the Democratic Progressive Party (DPP) proposed Friday. As they could not agree,
ROAD SINKING: The road surface of Qingcheng Street near the intersection with Xingan Street in Taipei’s Songshan District collapsed on Friday at about 9pm Grouting was yesterday used to repair a section of road in Taipei, after work on a construction site caused the surface to partially collapse on Friday evening, the Taipei Construction Management Office said yesterday, adding that nearby buildings were not affected. The road surface of Qingcheng Street near the intersection with Xingan Street in Taipei’s Songshan District (松山) collapsed at about 9pm on Friday. When police arrived they found four cars parked by the roadside tilting to one side. Police estimated the area that had subsided was about 4m by 30m, and was about 1.5m deep. They cordoned off the surrounding area
