1 . Natural disasters can cause environmental changes. How will cities use technology to maintain (维持) power during natural disasters in the future? Some smart middle school students are already thinking about this question.
Teams of students from around the world explained their ideas on this topic at the Future City competition, which recently took place in Washington, DC. Students from Justice Page Middle School in Minneapolis, US, were on one of the teams.
Instead of using popular technologies like flying cars and AI, the students from Justice Page Middle School took a more simple approach to the topic. They spent weeks developing their ideas and building a model to show them. They chose the city of Maui in Hawaii as the setting for their project. They chose this city because several different kinds of natural disasters had happened there in the past.
In their project, they covered roofs in the city with solar panels (太阳能电池板), which can produce and store power. When a power failure happens, the stored power can be sent to different neighborhoods.
The students brought their model to life with 3D printing technology. They printed the parts they needed. To make the model more real, they made a base out of wood and grass. The model has lights and even a small train that travels back and forth.
The team did not win the competition, but the experience was valuable. One competitor of the team, Ryan Rowell, 13, said he thought it was cool to think about things that he hadn’t considered before. He also saw how other teams advertise their models and interesting ideas. He said he wanted to keep learning about engineering.
