Underground device to make energy
recyclable The city is preparing to put into use effectively heat as an energy
source. A recycling device is installed under a building and by energy exchange between heat inside the building and
underground, the building can be kept cool in summer and warm in winter so as to save energy. Cherndu has applied the technology to use on a trial basis and the central government has decided to support the city’s tentative move. The city expects to find a breakthrough in
recyclable energy research and development in the near future.
