Abstract: There is provided an ornament having liquid therein. The liquid in the device is effectively insulated from the electronic and mechanical structures, and the outside air can not enter into the liquid to cause the liquid to deteriorate or become cloudy, and the liquid in the container can not penetrate into the electronic and mechanical structures in the base to result in electrical and mechanical failures. Furthermore, the provision of the buffer members ensures that no crack will occur in the joint between the enclosure and the base body in cold or hot environment. The enclosure may be optionally transparent or opaque and thus the light source for decoration purposes may be provided in the liquid or in the base as needed.

Abstract: The invention relates to an ornament having a liquid therein. By providing a sealing and insulating enclosure it can effectively insulate the liquid in the container from the outside and the electronic and mechanical means for providing the decorative effects and can avoid the pollution by grease or oil and thermal expansion.

Abstract: A system for controlling the HVAC system of a building to reduce overall electrical costs is disclosed. The system develops an energy usage and storage strategy which is a function predicted ambient temperatures, predicted building load requirements and the power company's rate structure.
