According to the car owner's recollection, he had previously noticed that turning on the headlights while the vehicle was ...

The 'energy reserve' function of the battery is key. It needs to provide a strong current during ignition, and after the engine is off, it powers operations like the windows and audio system. Once the ...

A regular shop-bought mushroom has been turned into an electricity generator in a process scientists hope will one day be used to power devices. The “bionic mushroom” was covered with bacteria ...

Made in Hong Kong, the droplet-based electricity generator has a high energy-conversion efficiency and power density thousands of times bigger than its counterparts.

The City University of Hong Kong researchers behind the device, which they're calling a droplet-based electricity generator (DEG), say that a single rain droplet can briefly generate 140 volts.

For generating electricity, the thread of the “fiber-shaped fluidic nanogenerator” (FFNG), which is what the researchers are calling their minute electricity generator.

Generating electricity from raindrops efficiently has gone one step further. A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based ...
