green wind by bhmo design team from china

The wind that was generated by the high-speed subway train can be converted to electric energy by the “green wind”. It is effective wind power. And the electric energy is used to light the metro. When the metro running quickly in the tunnel, it will generate wind with high speed and press. If the wind crosses the “green wind” equipment fixed on the top of the metro, the energy will be collected and stored. And then it will be converted to electric energy by a converting module. The electricity is used for light the inner of metro finally. This process continues as long as the metro runs, and it helps to save energy greatly.
The “green wind” contains two parts. The wind collecting equipment is fixed on the top of the subway cars to collect wind, convert and store energy. And the lighting equipment is assembled inner to light the body of the cars or reserved.
