A college student in Nanjing was recently granted a design patent for her invention, an energy-saving lamp.

Inspired by the architecture of the Pompidou Centre in Paris - which has an exposed steel structure and prominently displayed utility pipes on the exterior - the patented lamp is made of a faucet, water pipes and a discarded metal base.

It "can also be used as a house decoration and a spot for hanging keys", said inventor Jia Menglin, a junior at Nanjing Forestry University.
