From a climbing robot named "Spiderman" to an improved biomimetic solar panel inspired by a smoggy day and a 3D print model of an assembling department for elderly people, 18 teams brought their projects to compete for the top 12 spots in the final innovation contest at the China Science and Technology Museum recently.

After the first round of the competition in July, 58 teams from both high schools and universities qualified for the second round of the National Youth Scientific Innovation and Experiment Contest Beijing division.

Xu Wenjie, a student from Shanxi Traffic Technician College, spent five months designing a cross-sea bridge model for the Qionghai Strait. The bridge will not only allow cars and trains to cross the strait, but also allow ships of certain sizes to go through the bridge. Fans on the sides of the bridge can take advantage of the wind to generate electricity, as well as reduce wind damage.
