音频一：

Three university students in Santiago, Chile, have developed a plant-powered device to charge their mobile phones. The three engineering students got the idea for the device while sitting in their school's courtyard.

音频二：

Their invention is a small biological circuit they call E-Kaia. It captures the energy which plants produce during photosynthesis-a process of converting sunlight into energy.

音频三：

The E-Kaia solved two problems for the engineering students. They needed an idea for a class project. They also needed an outlet to plug in their phones. The E-Kaia is able to fully recharge a mobile phone in less than two hours.
