A device for communicating and monitoring railway tracks includes a plurality of communicating and monitoring terminals arranged along the tracks. Each of the terminals includes an image-capturing module, a wireless communicating module that allows for communication between the terminals and with a train, and a module for storing electrical power continuously supplying the image-capturing module and the communicating module. Each terminal also includes a power-generating module for supplying the module for storing electrical power. The power generating module recovers energy from the air displaced by the train running over the railway track. The device permits permanent monitoring by capturing images and makes permanent wireless connections available to the trains.

A method of selling goods to a customer, comprising: loading a variety of goods into a plurality of dispenser robots; receiving an order for goods by a customer over a communications network; causing a delivery vehicle to move along a guideway to at least one location of at least one dispenser robot in the plurality of dispenser robots responsive to receiving the order; causing dispensing of goods from the at least one dispenser robot into the delivery vehicle; causing the delivery vehicle to load onto an aerial tramway responsive to causing dispensing of the goods;

causing the delivery vehicle to move to a destination point on aerial tramway; and causing presenting the goods in the delivery vehicle to the customer at the destination point.

A wind energy-based cooling system for a storage container such as a rooftop residential water tank. The system includes a housing having one or more walls defining one or more inner surfaces and one or more outer surfaces. The housing includes one or more ventilation openings. Means are included for connecting the housing to an access opening of the storage container. The housing and storage container together define an enclosure. A bearing is positioned within a wall of the housing, and a support shaft is held within the bearing. A wind turbine is in connection with the support shaft and configured to capture wind energy outside of the enclosure. A flywheel is in connected to the turbine as well as a gearing arrangement. A rotor is positioned within the enclosure in connection with the gearing arrangement and configured to direct cooling air towards the contents of the storage container.

A floating offshore wind turbine integrated with a steel fish farming cage mainly includes a wind turbine, a wind turbine tower, a living quarter, a floating wind turbine foundation in a conic steel structure, a mooring system, a lateral net encircling the floating wind turbine foundation, a bottom net, and lifting systems. The upper end of the wind turbine tower hosts a wind turbine, and the lower end of the wind turbine tower is fixed on the floating wind turbine foundation. In the present invention, the inner space of the floating wind turbine foundation is used to form a huge farming cage, which functions for the objectives of power exploitation on the top and fish farming at the bottom. The foundation has excellent stability and seakeeping performance, and is applicable to deep waters.

Provided is a hybrid street light in which an effect of facilitating use, by people, of a space under illumination is obtained. The hybrid street light includes: a support column; a power generation device main unit including, at an upper portion of the support column, a vertical-axis wind turbine power generation device and a solar photovoltaic power generation device; a lighting device installed around the support column and powered by either or both of the power generation devices; and a seat attached to the support column. In the daytime, power is generated by the solar photovoltaic power generation device. The wind turbine power generation device generates power by day and night as long as wind is available. Since the seat is attached to the support column, an effect of facilitating use, by people, of a space under illumination is obtained.
