A storage shed for storing items such as grain, equipment, implements and/or machinery, the storage shed including: a floor; one or more spaced apart walls mounted on the floor; a roof; wherein the walls and roof and floor provide a storage volume and are sealed together to inhibit ingress of vermin and to maintain a selected ambient pressure inside the storage volume, and a pressure relief valve operatively connected to the floor, roof or wall to relieve internal pressure in the storage shed.

The present invention provides a bidirectional energy-transfer system comprising: a thermally and/or electrically conductive concrete, disposed in a structural object; a location of energy supply or demand that is physically isolated from, but in thermodynamic and/or electromagnetic communication with, the thermally and/or electrically conductive concrete; and a means of transferring energy between the structural object and the location of energy supply or demand. The system can be a single node in a neural network. The thermally and/or electrically conductive concrete includes a conductive, shock-absorbing material, such as graphite. Preferred compositions are disclosed for the thermally and/or electrically conductive concrete. The bidirectional energy-transfer system may be present in a solar-energy collection system, a grade beam, an indoor radiant flooring system, a structural wall or ceiling, a bridge, a roadway, a driveway, a parking lot, a commercial aviation runway, a military runway, a grain silo, or pavers, for example.

A prestressed concrete roof for a cylindrical tank is provided with a plurality of prestressed concrete (PC) steel members which are disposed side by side in a circumferential direction at an outer circumferential side of a discoid roof and each of which extends in a radial direction, in which the plurality of PC steel members are made up of both arm parts of folded PC steel members that are folded so as to be open to the outer circumferential side of the roof in a plan view.

A jack for lifting segments of a structure includes a pair of masts, a mast base, a mast cap, a hydraulic ram, a bottom bracket and a shuttle. The masts are identical and upright with a plurality of evenly spaced holes. The mast base supports the mast and the mast cap receives the upper ends of the masts and maintains the masts in a parallel, relationship. The hydraulic ram moves between a retracted position and an extended position with a stroke distance which is significantly less than the mast height. The bottom bracket is removably pinned to the masts and receives and supports the lower end of the hydraulic ram. The shuttle receives the upper end of the hydraulic ram. The bottom bracket and shuttle, when not pinned to the masts, can slide vertically up the masts. The shuttle includes features for connecting to a segment of a structure.

Modular plant cultivation and storage systems are disclosed herein. Such systems may enable individuals to grow, or obtain managed growth of, various plants, such as flowers, trees, fruits and vegetables, herbs, fungi, medicinal plants (e.g., marijuana, where legally permitted), etc. The modular plant cultivation and storage system may be a professionally equipped and staffed cultivation center where individuals can bring seeds and/or seedlings to grow and be serviced, monitored, and stored for a fee. Such modular plant cultivation and storage systems provide a safe, effective method to produce a high quality, high quantity plant products with additional services that can test and produce other products from the initial crop.

Aspects of the disclosure relate to temporary storage systems for the temporary storage of agricultural grain products. The temporary storage systems include an enclosing retaining wall comprised of a plurality of free-standing wall sections. The enclosing retaining wall can include multiple free-standing wall sections arranged in a circular, oval, or substantially rectangular shape. Each free-standing wall section includes one or more corrugated panels coupled with one or more support structures. The support structures can be constructed from a rigid material and include ground supports, which permit the free-standing wall sections to maintain a predetermined angle based on the angle of repose of the agricultural products stored. Each corrugated wall panel includes a plurality of perforations and a plurality of corrugations configured to provide ventilation to the grain product, while maintaining the necessary rigidity to retain the loads imposed by the granular material.
