Abstract: A multiplatform heating ventilation and air conditioning control system configured to maximize energy efficiency in maintaining desired conditions within an area through beneficial use of natural energy sources. In some embodiments, the multiplatform heating ventilation and air conditioning control system can include sensors and a control system. In some embodiments, the sensors can detect conditions inside and outside of the controlled area to determine the most efficient method of maintaining desired conditions.

Abstract: A system and method of creating and operating a utility structure coupled to a second structure is provided. A utility structure can include a renewable energy source, a control system, water heating system, a communications system, and a solar hot air module. In connection with these features, a utility structure can provide utility access, heated and/or cooled water, and HVAC to the connected structure. A utility structure can be free standing, portable, or attached to another structure.

Abstract: A system and method is provided for filtration and purification of a liquid. A purification system can be used for filtration and purification of water. A system can include a raw water treatment system, an ultra filtration system, a reverse osmosis purification system, and a solar power system. A purification system can include hardware and controls for decreasing energy use and system inefficiency by monitoring and controlling temperatures of individual components, of the system, or of the purified liquid. A purification system can include a wetted ground and ground monitoring system control or improve the effectiveness of a ground.
