Abstract: An outdoor heat preservation dining stove includes a base and a plate. The top of the base is recessed inwardly to form in turn a holding cavity and a water storage cavity which are connected, wherein the water storage cavity is used for storing hot water, and the plate is placed in the holding cavity with its bottom contacting the hot water in the water storage cavity. The inner side of the base is provided with an overflow groove, located at the interface between the holding cavity and the water storage cavity, to receive the hot water overflowing from the water storage cavity. The heat preservation dining stove has the advantages of easy operation and maintenance, simple manufacturing process, preventing the food pan from floating and improving the heat preservation effect, convenient to carry and not affect the taste of food.

Abstract: A sun tracking plant growing system includes a body having a first face, a second face opposed to the first face and a peripheral connecting edge which is relatively small, as compared to the size of the first face and the second face. A mounting enables the body to pivot about a pivot axis. Plant supports, which receive plants, are supported by the body. A sun tracking mechanism is provided which senses or calculates the position of the sun and adjusts the orientation of the body about the pivot axis to maintain a selected portion of the peripheral connecting edge of the body facing the sun so as to provide desirable and naturally attenuated sunlight exposure according to plants' needs on both faces throughout a day. This system allows that multiple rows or single row of the plural bodies are arrayed closely together without creating shadows to each other.
