Abstract: The invention discloses a photobioreactor featuring a microalgae cultivation chamber in the form of a closed flat duct irradiated by sunlight. The flat duct is constructed from an inflatable sleeve made of transparent polymer film. This inflatable sleeve is sandwiched between a bank of frames with wire nettings, plates of foamed plastic, a variable air pressure mattress located underneath the inflatable sleeve, and a thermo-insulating transparent inflatable mattress and glass panes above. The variable air pressure mattress facilitates mixing of the microalgae suspension with the gaseous medium containing carbon dioxide and regulates the temperature of the microalgae suspension in the flat duct.

Abstract: A cooking box functions by the supply of an external source of hot air with a temperature higher than 100° C. This external source of hot air is preferably a solar thermal collector of a flat-plate type or CSP (concentrating solar power) type. Auxiliary details in the cooking box allow to achieve high heat transfer parameters from the hot air to cooking utensils placed in the cooking box. The cooking box can comprise a PCM heat storage system for the application of stored heat for cooking or heating food, when the external hot air is not supplied.

Abstract: An invention proposes a novel steam accumulator, which is designed as a multilayer reservoir with application of phase change materials (PCM) for alternative steam condensation—condensate's evaporation in cycles of periodic charging-discharging such steam accumulator. PCM is contained in sealed impermeable packs, which are placed vertically on metal trays; the metal trays are arranged in a multilayer form in a thermo-insulated reservoir. Fabric or wire netting components, serving as wicks, ensure nearly complete wetting of the sealed packs' exterior surfaces by the condensate during its evaporation, facilitated by the melted PCM within the packs.

Abstract: A heat or cold storage multilayer tower has athermo-insulated housing with a multilayer system of rigid blocks, Each rigid block has a set of narrow vertical ducts, when these narrow ducts are alternatively open or provided with sealed flexible bags, which are ufabricated from polymer film or metal foil and contain a phase change material (PCM). The rigid block are fabricated from ceramics, glass, glass ceramics, polymer fibro reinforced concrete or glass-fiber reinforced concrete.

This construction provides effective heat transfer between a heat transfer fluid (HTF) and PCM in the processes of charging and discharging of the sealed flexible bags with heat or coldwith high values of stored thermal energy for specific volume.

The integrated inductor can optionally include multiple spaced apart conductive layers that are electrically coupled. The integrated inductor can optionally include a series of conductive traces and plated through holes or vias that together provide a current path with multiple turns.
