辽宁省实验中学东戴河分校2018-2019学年高二上学期英语12月月考试卷
As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.
Three Chilean students got the idea for a plant-powered device(装置) to charge(使……充电) 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. “'Why don't you have a socket, if there are so many plants? 'After that, we thought, 'why don't they have a charging outlet(插座)? Because there are so many plants and living things that have the potential to produce energy, why not?'”
Their invention—a small biological circuit called E-Kaia—uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.
"It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them." said Mauricio Cifuentes.
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 notebook, which had no power, and the mobile phones, 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 bio-circuit makes good use of their excess(过多的) power.
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 patents(专利) on their technology, and expect the E-Kaia to go on sale in the near future.
