Technology has brought about so many crazy advances in the modern age. It has made our big world so much smaller, both when it comes to communication and travel. Traveling across the country or even the world is faster and safer than it has ever been. Technology has caused first world housing to become status symbols and works of art, rather than mere shelters from the elements. If you have travelled to some places outside of our country, it is very easy to see that things we take for granted are a great luxury elsewhere. Even something as simple as heating and air conditioner systems is not as readily available as you would think. This is why I prefer heating and air conditioner systems that work with what nature already provides, such as the swamp cooler. Swamp coolers are much cheaper than traditional heating and air conditioner systems. They also are more energy efficient and better for the environment by far. The portable swamp coolers use easy to understand technology to cool a home When compared to air conditioner systems that uses refrigerant, the swamp coolers can cost up to 50% less. The swamp cooler system does not add ozone damaging gases into the environment which is wonderful for the Earth. The means by which swamp coolers cool the house is that it cools the air simply using air motion and water. And it works best when there is fresh air available from an open door or window. The constant circulation of fresh air ensures that your indoor air will be of a much higher quality than just using a traditional heating and air conditioner system.
