Abstract: A dry salt therapy device includes a blower, an exhaust passage fluidly coupled to the blower, a grinding chamber configured to aerosolize salt, and a salt vent fluidly coupling the exhaust passage and the grinding chamber. A flow structure may be provided. The grinding chamber may have a particular aspect ratio, tip clearance, or floor clearance. Salt may be delivered to a user without contacting the user, the salt being delivered in a jet having a particular diameter at a particular distance. The device can include a converging-diverging nozzle in the exhaust passage. The salt vent may protrude into a center of a flow of air through the exhaust passage.

Abstract: The invention relates to a hydroponic system and method. In various embodiments the hydroponic system and method includes modular plant containers in communication with a fluid reservoir and with one another. Such containers may be hung in vertical columns in window gardens. The containers may be made from low-impact or recycled materials, such as water bottles. The system includes a vertical fluid circuit and an air introduction assembly for supplying water, air and nutrients from the reservoir to the containers.
