Objects of the present invention are to provide a film for an agricultural greenhouse that can maintain a CO.sub.2 concentration necessary for the photosynthesis of plants even when ventilation is not performed and to provide an agricultural greenhouse using the film. The film for an agricultural greenhouse of the present invention is a cellulose film which contains a cellulose acylate resin and has an equilibrium moisture content of 4% to 8% at a temperature of 25° C., a relative humidity of 80% and a thickness of 60 to 200 μm.

A plant factory includes a culture room, a lighting assembly, a CO.sub.2 concentration generation controlling module, an air conditioning module, a nutrient supplying module and a controlling module. The plant factory controls the lighting assembly to meet the lighting requirement of the different types of plants at each growth stage and the different types of plants at each growth stage are in the optimal growth state and grow in a predetermined manner of meeting the corresponding growth schemes. The plant factory improves planting efficiency and realizes lean production to achieve the zero inventory target meeting plant production characteristics.

A flexible datacenter includes a mobile container, a behind-the-meter power input system, a power distribution system, a datacenter control system, a plurality of computing systems, and a climate control system. The datacenter control system modulates power delivery to the plurality of computing systems based on unutilized behind-the-meter power availability or an operational directive. A method of dynamic power delivery to a flexible datacenter using unutilized behind-the-meter power includes monitoring unutilized behind-the-meter power availability, determining when a datacenter ramp-up condition is met, enabling behind-the-meter power delivery to one or more computing systems when the datacenter ramp-up condition is met, and directing the one or more computing systems to perform predetermined computational operations.
