Evaporative cooling was used as early as the Old Kingdom of Egypt, around 2500 B.C. As you can imagine, a clay pot cooler does not use electricity. It uses a porous clay pot (filled with wet sand) containing another smaller inner pot (which can be treated to prevent penetration by the liquid) within which the […]

Evaporative air coolers are a very good energy efficient alternative to classic, freon air conditioners. In fact, our own bodies are cooled by transpiration through the same evaporative cooling effect. A New Jersey startup named Quilo is launching these days the device that they say will revolutionize cooling energy efficiency. How Quilo Works Quilo is […]

Evaptainers is a portable cooling system, which runs solely on water and sunlight- no electricity or toxic chemicals needed. Keeping things cool is often considered kind of a given by many of us. Regardless of how many articles are written and appeals are filed in order to raise awareness of electricity consumption, pollution, and the effects on our […]

Q: Panasonic’s New Spherical Fan Revolutionizes Low-Power Cooling

Ovidiu Sandru — Tue, 07 Apr 2015 06:17:20 +0000

When talking about cooling a room, people always think of air conditioners. Panasonic has recently unveiled its plans to produce an efficient spherical air blower that ejects seven times the wind it absorbs. Well, that may sound like wishful thinking, but Panasonic’s spherical air blower actually uses smart physics to do that. They called it “Q.” […]

Evaporative cooling was the brainchild of Ron Judkoff, a Peace Corp volunteer working in Senegal in the 1970s. Judkoff is now the director of Buildings and Thermal Systems at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). Judkoff noticed the Sengalese used porous clay pots that allowed evaporation while actively cooling the water […]

Water Evaporation From Plants Helps Cool Down The Climate, Study Demonstrates

Ovidiu Sandru — Tue, 27 Sep 2011 09:05:15 +0000

A team from the Carnegie Global Ecology department have recently concluded that water evaporation on Earth actually cools down the atmosphere and fights global warming, but not in the way you’d be tempted to think. You probably know from elementary classes that evaporation happens with energy consumption, thus taking the heat from the object and […]
