日本正在沿海试验一种长10米的收集阳光的装置,该装置可把光线射到水下,以利于海藻和浮游生物的生长。平台上安装着反射阳光的许多镜子,光线经棱镜折射入水下5米处。以阳光为动力的电机可使镜子跟踪太阳。经一年试验后,该装置即可正式投产。
Japan is experimenting with a 10-meter-long sunshine-collecting device that shines light underwater to help algae and plankton grow. The platform is equipped with many mirrors that reflect sunlight and the light is refracted by the prism into the water 5 meters below. The sun-powered motor allows the mirror to track the sun. After a year of testing, the device can be officially put into operation.
