The present invention is generally related to a system for growing plants in a controlled environment, and more particularly related to a system for growing plants in a mobile and controlled environment wherein the system may be built from re-purposed or recycled materials such as one or more shipping containers or box trailers. The herein disclosed system for growing plants in a mobile and controlled environment may be utilized in locations which are not normally suitable for growing and harvesting crops, thus benefiting the local populations of historically unproductive areas.

A radiational cooling film providing a variable wavelength which determines a solar heat shielding rate according to the internal temperature of a facility and changes a wavelength conversion section of the film exposed to sunlight to radiate a necessary wavelength according to the growth stage of plants, and a wavelength conversion device and system using the same are provided. The radiational cooling film providing a variable wavelength includes a base layer including a first region and a second region on one surface, a heat barrier layer disposed on a part of the other surface of the base layer, the first region being provided with the heat barrier layer, and the second region being not provided with the heat barrier layer, and a wavelength conversion layer including a plurality of wavelength conversion sections separated from each other in each of the first region and the second region.

The present disclosure is directed to a new and improved system and method for on-demand insulation, which may be deployed layers of a double-layered window. An on-demand thermal insulator system has a body that is configured to transition between a collapsed form non-deployed state and a deployed state. The body while in the non-deployed state allows a transfer of thermal energy through a defined boundary. The body while in the deployed state in resisting the transfer of thermal energy resists transfer through the defined boundary. In particular configurations, the body has a layer disposed between two material that receives fluid when transitioning from the non-deployed state to the deployed state.

Top furling automated retractable greenhouse cover is a retractable cover for a greenhouse that is mounted on top of the greenhouse. Top furling automated retractable greenhouse cover comprises: a spine clamp, a left furling cover assembly, a right furling cover assembly, a hinge pin assembly, and an electrical control box. Left and right furling assemblies each comprise a curtain or cover, a furling rod, a furling motor, and a support arm. Electrical control box sends electronic signals to cause left and right covers or curtains to furl above the greenhouse when retracted and to unfurl down to the ground when extended to cover the greenhouse. The top-mounted design allows efficient use of gravity to apply tension to the furled rolls.

Automated shading devices for buildings including one or more shade panels, each with a first end attached to a dispenser, a drive mechanism mechanically connected to the dispenser and configured to cover or uncover a translucent panel with the one or more shade panels, and a control mechanism connected to the drive mechanism and configured to automatically cause the drive mechanism to cover or uncover the translucent panel in accordance with a predetermined schedule. The dispenser is held in tension upon the translucent panel via a telescoping arm. In some examples, the devices include a drive mechanism located proximate to the dispenser. In some further examples, the devices include a drive mechanism located near the base of the telescoping arm.

A device for covering a surface includes a cover (9), a drum mounted to rotate and able to wind or unwind the cover, and a translation system. The translation system includes a pair of closing spools (11r) mounted to rotate about a closing shaft (12) and each coupled to a closing cord (1c) to move the drum on rails (6) in a closing sense (Dc), and an axle shaft (12) coupled to the drum (2t) the rotation of which enables winding of the cover onto the drum (2t) and to move the cover on the rails in an opening sense (Do). A motor (M) connected to a driving shaft (10M) and coupled to a clutch system is configured to enable the driving shaft to actuate alternately rotation of the closing shaft (11) and the axle shaft (12).

A rail element is provided having a longitudinal axis, a first longitudinal end and a second longitudinal end longitudinally spaced from the first end along the longitudinal axis. The rail element includes a rail body longitudinally extending between the first longitudinal end and the second longitudinal end, the rail body defining therein at least one longitudinally extending first lumen having a longitudinally co-extensive transverse first opening, the rail element being configured for being mounted to at least one longitudinal support member in load bearing contact therewith in operation of the rail element. The rail element is configured for being mounted to the at least one longitudinal support member in a non-longitudinal manner A system for covering an area incorporating such rail elements is also provided, as well as a method for using such a system.
