The present invention is directed to a mobile light tower that utilizes multiple sources of energy to provide a highly energy efficient source of illumination. The lights of the light tower draw power from the energy stored in the batteries. During the day, solar energy can captured and stored in batteries. In times of cloud cover, or at night, wind energy can be captured and stored in the batteries. Additional alternative energy sources can also be incorporated. In the event that neither of these sources are sufficient, a fuel powered generator can be utilized to generate energy to be stored in the batteries.

The present disclosure relates to a water sprayer and various features thereof. More particularly, the present disclosure relates to a water sprayer for use in a pool, and to a method for using the same. In various embodiments, the water sprayer may include a water output mechanism and a light source that is powered by flowing water to provide illumination functionality.

An adsorption bed utilizing Metal Organic Framework canisters to process flue gasses exiting from power generation plants. High temperature flue gas from a power generation is cooled and enters MOF containers where CO.sub.2 is adsorbed. CO.sub.2 is then de-adsorbed with additional high temperature flue gas. CO.sub.2 is collected and removed from flue gas. Electricity is generated using the heat differential and collected to power the device. Electronic control system uses sensors and controls valves, pumps, cooling system and MOF gates.
