JR East's ambition: electricity generation by train riders

TOKYO, Japan - East Japan Railway Co. will be testing piezoelectric devices (photo) at Tokyo Station on Jan. 19 to produce electricity through vibration power as train riders walk through railway ticket gates. JR East engineers estimate the power generated by one person walking past a piezoelectric floor device laid at a gate will be enough to light up a 100-watt electric bulb by 0.01 second, or 80 minutes of lighting per day. Piezoelectric devices in speakers produce vibration, and sound, when activated by electric current. Using the reverse principle, JR East engineers have been testing the use of vibration on pieozoelectric devices to produce electricity. The tests at Tokyo Station's Yaesu North entrance will run until early March. The amount of electricity produced will be shown on a monitor near the gate.

NW China province sees new energy development boom

STORY: NW China province sees new energy development boom DATELINE: July 28, 2022 LENGTH: 00:01:28 LOCATION: LANZHOU, China CATEGORY: ENVIRONMENT SHOTLIST: SOUNDBITE (Chinese): ZHANG CHONGCHONG, Deputy general manager, Lanzhou Dacheng Technology Co., Ltd. STORYLINE: Northwest China's Gansu Province, rich in wind and solar energy, is seeing a new energy development boom as the country seeks to reduce carbon emissions and improve the energy mix. In Gansu's Dunhuang City lies China's largest molten salt solar thermal power station. When operating at full capacity, it can generate 100,000 kWh of electricity per hour, enabling one million 100-watt light bulbs to work for an hour. Next to it sits the Lanzhou Dacheng Dunhuang 50MW molten salt Fresnel concentrating solar power (CSP) project, which can generate electricity 24 hours a day in normal weather. SOUNDBITE (Chinese): ZHANG CHONGCHONG, Deputy general manager, Lanzhou Dacheng Technology Co., Ltd. "Dunhuang has rich solar energy resources and is suitable
