In 1902, Willis Carrier invented the vapor compression air conditioning system, and is still the most commonly used air conditioning technology today. This compressor-based system consumes a lot of energy and uses chemical refrigerants that harm the environment, like chlorofluorocarbon and hydrochlorofluorocarbon. Recently, in the National University of Singapore (NUS), researchers have developed a new eco-friendly, water-based air conditioning system that runs without the need of compressors and chemical refrigerants. This water-based air conditioning system uses membrane technology to remove moisture from the outside air and is cooled by using water instead of chemical refrigerants. It consumes approximately 40% less electricity than compressor-based air conditioners and can cool air to as low as 18 degrees Celsius. In addition, this new system can produce 12 to 15 liters of potable drinking water a day by releasing cool air that is less humid than air in the surrounding environment. GO GREEN… SAVE GREEN!!! KOG
Today, people are moving towards more eco-friendly solutions in many facets of their lives, including the bed that they sleep in. Organic mattresses are available for those who seek an eco-friendly solution for where they sleep. The organic mattresses available today vary on their organic substance and only some are 100% organic, but others do carry some environmentally positive qualities. Whether you are environmentally-concerned, health-conscious, or allergy-sensitive, organic mattresses may be right for you. Although, organic mattresses can be very expensive, heavy, and require research to confirm environmental certifications; they are also highly durable, environmentally-friendly, and void from the risk of inhaling harmful chemicals, as opposed to non-organic mattresses.
