THE ART OF EVAPORATIVE COOLING.......

-
Nothing like a cool blast of air, or  a cold drink, on a hot day. However, most appliances used in "keeping cool" are "power hungry".  This leads to the question? How did people stay cool before Michael Faraday, invented a way for electricity to become viable for use in technology?

  • Ancient Egypt:According to archaeologists, there are Ancient Egyptian fresco painting of slaves fanning large porous clay pots. This is the first record of the use of evaporative cooling.
  • Roman Empire:Affluent Romans circulated water from the aqueducts through the walls of their homes to maintain a cooler temperature.
  • Medieval Persia: The first man made structures were constructed in the form of towers. These towers trapped wind, and funneled it past water at the base and into a building. Nowadays. these coolers have been modified into evaporative coolers(Coolere Âbi) and  are widely used in Iran. 
  • Renaissance Era: Leonardo DaVinci, was credited with being the inventor of an early mechanical air cooler. A water wheel that guided cool air into a room.
  • After 1831:
  • In early 1900's America: Air washers were invented. The air washers passed air through water spray, which cleaned and cooled the air in textile mills and factories in New England and the Southern coastline.
  • 1995: Mohammed Bah Abba invented the Zeer pot. Utilizing evaporative cooling to preserve vegetables and fresh produce. 
It has been 182years since Jacob Perkins, built the first refrigerating machine,and  114 years, since  Willis Haviland Carrier invented electrical air conditioning. Evaporative  cooling, is still being used, without an external energy source, and as an environmentally responsible cooling system.
Did you know, evaporative cooling is used to reduce the temperature in silkworm rearing houses?

SO NOW YOU  KNOW!!!!

  Fossil fuels have been the primary source of energy in the form of crude oil.  For decades,petroleum products have been used to power cities, cars, machinery and much more the world over. However, environmental awareness,  has highlighted negative environmental impacts,   particularly, climate change . This has led to the exploration of  renewable energy sources and advancement in clean energy technologies for ,solar, wind, and hydro power.  Bio-fuels , are being championed as  more ecofriendly alternatives to petroleum. But,there have been challenges, in area of demand and supply. There has also been  debate about  food shortage, versus energy production. In the past, energy from waste , has been criticized because of the use of heat, and its resulting fumes, which could be harmful. It appears that this issue may have  been addressed. A Japanese inventor, Akinori Ito ,  invented a household appliance, that can convert pl...

Food, sustains. art,  expresses . So, what do you get when you combine them?   Rice , has been described as a staple food, for more than half of the world's population. It is typically grown in flooded fields known as rice paddies. Through the tanbo art process, rice paddies are being transformed into stunning works of art. It began,in  Inakadate , Japan. In 1993, the first rice paddy art was created, using purple and yellow rice plants. It was the picture of Mt. Iwaki along with letters. Here's a picture, beautiful isn't it?  How is it done?  To begin with, it takes about 1200 people  and costs $35,000 to create. Followed by these steps STEP 1:Choosing a design STEP 2: A sketch is made of the desgin STEP 3: A three- dimensional perspective is generated STEP 4: Selection of  the rice varieties to be used. STEP 5: Creating the design plan using Computer Aided Drawing (CAD) STEP 6: The design is drawn on the field u...
