<p>A method of converting air internal energy into useful kinetic energy is based on air flowing through substantially convergent nozzle, which accelerates the air as the cross section of the nozzle decreases thus increasing the air kinetic energy. The increment of the kinetic energy equals to the decrement of air internal energy, i.e., air temperature. Within said nozzle a turbine is placed to convert airflow kinetic energy into mechanical energy that transformed into electrical energy or transferred into a gearbox to provide driving moment. Devices uses this method could use natural wind as airflow source or artificial airflow means. Devices, which incorporate means to create airflow artificially, can be used as engines for land, sea and flying vehicle. Since air temperature drops within the nozzle, moisture condensation exists and liquid water can be accumulated for further use.</p> |
