A crop production system (100) for a controlled plant growing environment is provided. A subassembly comprises a guide portion that includes passive guides (104, 504, 904, 1004) radiating outward from a central portion (102, 502, 520, 911). Each passive guide may be separated from two adjacent passive guides by respective angles. Each passive guide has a first end proximal to the central portion and a second end distal to the central portion. Each passive guide is configured to guide plant growth modules (210). The plant growth modules are movable between the first end and the second end of each passive guide. An active guide (406, 907, 1007) causes the plant growth modules to travel in a first direction along the passive guides as the active guide is moved.

A ten-device-in-one reconfigurable adjustable carport (capable of functioning as a privacy screen, a wind screen, a cabana, a dog run, a retail-tradeshow booth, an attic, a storage, a picnic table, a kennel, and a carport) comprises: a canopy, roof spines, roof ribs, leg posts, T-shaped joiners and X-shaped joiners spring-snappingly connected to the roof spines and roof ribs and leg posts for configuring the ten-device-in-one carport as a car canopy and a greenhouse and an enclosure and a barrier and a cabana and a privacy room and a privacy screen and a tradeshow booth and a wind barrier, panels, door-frame panel, panel-to-panel-securing brackets and panel-to-post-securing brackets bolted to the panels and the door-frame panel and the roof spines and the roof ribs and the leg posts for configuring the ten-device-in-one carport as a dog run and a greenhouse and an enclosure and a barrier and bleacher shelves to store or display items and an attic to store items off the ground and a hanging cage to house animals off the ground and structures for displaying signs and roof storage, and bracket heads formed into the panel-to-post-securing brackets for automatically centering the bracket-head ends.

A translucent solar module assembly for integration with a greenhouse having a frame with a plurality of roof supports includes a pair of brackets attachable to each of the plurality of roof supports, a bi-facial solar panel attachable to the pair of brackets, and a pair of reflector rails attachable to each of the plurality of roof supports. A dichroic reflector is attachable to the pair of reflector rails.

The invention relates to a window for a building structure containing optically transparent and self-cooling coatings on a substrate. The optically transparent and self-cooling coatings has a multi-layered structure including a passive cooling layer, a near-infrared radiation absorption layer and a near-infrared radiation reflecting layer. The optically transparent and self-cooling coatings have a visible light transmittance of more than approximately 70%. In addition, an air temperature under the window under ventilation condition is reduced by at least approximately 2° C., and an air temperature under the window under insulated condition is reduced by at least approximately 8° C.

Portable ground cover devices, kits, and methods of assembly and use. A ground cover device includes a frame that may be assembled to a size suitable for use to cover a garden. A cover may be attached to the frame such that the cover is within an interior of the frame when assembled. When in an expanded configuration, the device may be placed over the garden to encourage plant growth and protect the garden from adverse weather, wildlife, and other environmental stressors. The device may be transitioned from the expanded configuration to a retracted configuration for storage or transport of the device when not in use.
