Abstract: The invention relates to an airflow power generation system and method. The airflow power generation system comprises a gas source, a channel comprising an airflow inlet and an airflow outlet, at least one unpowered ventilator, and at least one turbo-generating set. The airflow inlet is connected to the gas source; the unpowered ventilator is disposed at the airflow outlet, the unpowered ventilator is in a natural wind field; at least rotating blades of the turbo-generating set are positioned inside the channel. The unpowered ventilator operates to rotate under the action of temperature difference between inside and outside of the channel, and/or under the action of natural wind, to form negative pressure in the channel, to intake gas continuously from the gas source, to form airflow in the channel, to push the rotating blades to rotate via the airflow, and to drive the turbo-generating set to generate power.

Abstract: An air current generating system and method, includes an air source, a passage (105), at least a motor-less air pump device (104) and at least a turbine generating set (102, 103); the passage has an air current inlet connected with the air source and an air current outlet; the motor-less air pump device is mounted at the air current outlet and in the natural wind; the turbine generating set at least includes a rotating blade provided in the passage; the motor-less air pump device is driven by the air current from the air source and/or the outside wind to form negative pressure in the passage, absorbs air from the air source continuously and forms an air current in the passage, wherein the air current rotates the rotating blade to drive the turbine generating set to generate electricity.

Abstract: An active thermoregulation system without motivity and the method thereof are provided. The system includes a gas source, a regular closed space (1A), and an exhaust device without motivity (1B), a first connecting device (1G) and a second connecting device (1F). In the process of use, the regular closed space (1A) is separated from the external environment. The exhaust device without motivity (1B) includes a blade and a corresponding suction opening, which makes the exhaust device without motivity (1B) connect with the regular closed space (1A). During working process, by utilizing the temperature difference between the natural wind of the external environment and the regular closed space (1A), the blades of the exhaust device without motivity (1B) is driven to rotate. A low pressure is formed at the suction opening, and thus the air of the suction opening is extracted.
