Extracting Water from Humid Air Using Solar Energy in Humid Areas
The study aims to evaluate the technique of extracting water from humid air using solar energy through greenhouses in local areas. This technique is believed to provide limited amount of water in areas where potable water is not accessible or abundant. To solve this problem a pyramid-shaped device was designed, it is made of glass panels ad equipped with glass doors, fans operated by solar energy, and multiple shelves covered with fabric to act as Absorbent Calcium Chloride (CaCl2) with a 30% concentration. The doors are open during the night for absorption and closed during the day for energy-generating. Humidity, temperature, and atmospheric pressure are measured every two hours. The amount of water extracted in this area in one full day was around 3.0 liters a day for every square meter. Perhaps the limited amount of water is due to low level of humidity in the area: an average of 50% and temperature of F10 Celsius at night. However, the device itself is independent, does not need power sources, water sources, or infrastructure, can be installed in various places depending on humidity level as well as having the possibility of increasing number or size of device. This makes the device a promising, alternative and environmental friendly solution to produce water. Cost-effective and lighter material can be used to make the device, which will produce an easy-to-use and affordable devices. It is an area in need for further research to improve and further develop it.
EmerApp+: An innovative application for personal security
EmerApp+ is software designed for intelligent devices as a personal security database manager. In case of emergencies, it is an application which integrates location, tracking, and communication tools. It is triangulated between a database to a communication server as well as a second which is NASA server that offers climate and seismic information for Mexico. This application has two sources of communication, SMS messages and a newly created social network. In case of natural disasters, an extension for drones has been developed for this application, enabling rescue teams to delimit the land boundary where the disaster struck. In order to speed up the search and rescue operations a triangulation of network-drone- smartphone is completed.
