In order to develop the machinery for the preservation of the earth environment by extracting the clean natural energy, the new water wheels have been invented to use in the river and in the coast. One of the water wheel for the river is designated as the flutter-blade wheel, which is devised such that the several blades arranged around the wheel axis can be fluttered around the each blade axis with getting the fluid force in the water current. This blade can avoid the resistance induced by the reverse current by way of fluttering so as to get the current power efficiently. The experiments to measure the extracting power and the produce air from the oil-free compressor attached to the new wheel have been done in the laboratory and in the waterway from the Sai-river, which has indicated the possibility of applying to the field.The other wheel designated as wave-force wheel is devised such that the plate swinging around the suspending axis with received the wave force can rotate the axis, which drive the compressor linked to the wheel. The volume of the generated air by the wheel settled at the wave tank in the laboratory has reached to 13 L/min in even small waves whose period is 2〜5 sec and wave height 15〜30 cm. The experimental result is so favorable that the field type can be manufactured to advance the field research next year.

为了开发通过提取清洁的自然能源来保护地球环境的机械，人们发明了新的水轮，用于河流和海岸。用于河流的水轮之一被指定为颤振叶片轮，其被设计成使得围绕轮轴布置的多个叶片可以围绕每个叶片轴线颤振，从而获得水流中的流体力。该叶片可以通过颤振的方式避免反向电流产生的阻力，从而有效地获得电流功率。在实验室和赛河水道上进行了无油压缩机抽气功率和产气量的测量实验，表明了该新型叶轮在野外应用的可能性;另一种叶轮设计为波浪力叶轮，其叶片在波浪力作用下绕悬浮轴摆动，使悬浮轴转动，其驱动连接到车轮的压缩机。在实验室波浪水槽中，即使在周期为2 ~ 5s，波高为15 ~ 30 cm的小波浪中，车轮产生的空气量也达到13 L/min。实验结果表明，该样机可以在明年进行生产，以推进野外研究。
