A novel solar chimney-based liquid desiccation system includes a solar collector, an embedded desiccator with a novel structure, and a heated chimney. The solar collector heats up an incoming external airflow with solar radiation, and mobilizes the heated air to pass through the embedded desiccator. The embedded desiccator contains a liquid solution or another content that can undergo a thermal transfer process upon contacting the heated air from the solar collector. Typically, this thermal transfer process involves desiccation of the liquid solution and vaporization of some liquid or other elements. This desiccation process may be utilized to separate liquid from remaining contents, or as a purification process. The embedded desiccator is further connected to the heated chimney with a heated inner surface to minimize undesirable reflux and condensation within the chimney structure. A liquid recovery unit may also be added to the system to collect condensed liquid after desiccation.

Tray assemblies and methods of their use to dry products with sunlight. Such a tray assembly includes at least a first base having four side walls, a bottom wall, legs configured to support the bottom wall above the surface when resting thereon, side wall holes in the side walls, and bottom wall holes in the bottom wall. A cover is releasably coupled to the base to define an enclosure between the cover, the side walls, and the bottom wall. At least one window is provided in the cover to allow infrared radiation to pass therethrough that is absorbed by interior surfaces of the base to cause an increase in a temperature within the enclosure sufficient to increase a rate of drying products located within the enclosure.

The invention relates to a method and a device for obtaining dewatered biomass from algae and/or microorganisms. The concentrated biomass available as a result of the harvesting process is spread over an endless conveyor belt (1) and exposed to heated air on the conveyor belt (1). The air is heated by the sun and/or an air heater (5) in a closed system, the conveyor belt (1) being enclosed by a light-permeable casing (2). The drying process is carried out until a residual moisture is achieved, the dewatered biomass adhering to the conveyor belt (1) at the end of the drying process. Said biomass is separated from the conveyor belt (1) by means of a doctor- or scraper edge (9) and is gathered in a collection container (8).

The present disclosure provides a smart clothes drying device and a smart clothes drying method. The smart clothes drying device includes a light intensity sensor, an integrated controller, an umbrella and at least one clothes hanger. The light intensity sensor is to sense light intensity and output a light intensity signal. The integrated controller is to receive the light intensity signal and control opening or closing of the umbrella according to a comparison result of comparing the light intensity signal with a closing light intensity threshold or an opening light intensity threshold in such a manner that the integrated controller controls opening the umbrella when the light intensity signal is greater than the opening light intensity threshold, and the integrated controller controls closing the umbrella when the light intensity signal is less than the closing light intensity threshold.
