　　(2018·福建福州八县一中第二次月考)

　　 Three Chilean students got the idea for a plant-powered device to charge their cellphones,while sitting in their school's outdoor courtyard during a break from exams,with dead mobile phones.Then,one of them had an "aha" moment.

　　"It occurred to Camila to say about plants," said inventor Evelyn Aravena."There are so many plants and living things that have the potential to produce energy;why don't they have a charging outlet?"

　　Their invention -a small biological circuit (生物电路板) called E-Kaia-takes advantage of the energy plants produce during photosynthesis (光合作用).A plant uses only a small amount of that energy-the rest goes into the soil,and that's where the E-Kaia collects it.The device literally plugs into the ground and then into your phone.

　　"They brought the prototype;the prototype worked-and that's when it all changed.It's the most amazing project I've ever seen in my life,plain and simple,but it was transformational.And I began to support them," said Mauricio Cifuentes of Duoc University.

　　The device solved two problems for the engineering students-they needed an idea for a class project and an outlet to plug in their phones.

　　"Looking for a place to charge the mobile phones and the notebook that had no energy,we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

　　But plants are everywhere,and the biological circuit uses their excess power."There is a complete energy cycle of the plant.We decided to incorporate into the cycle,and then we would not affect the plant's growth.The biological circuit makes an acquisition and that is transformed into energy to later make charges for low consumption," said inventor Camila Rupcich.The E-Kaia doesn't carry much charge,but it's powerful enough to completely recharge a mobile phone in less than two hours.

　　The student inventors have applied for patent on their technology,and expect the E-Kaia to go on sale in December.
