Roofing Materials Might Replace Your Home Air Conditioner
November 1, 2023 | Leave a Comment
Researchers from McGill University, UCLA and Princeton have found in a new study the use of roof materials that radiate heat into the cold universe, even under direct sunlight, and how to combine them with temperature-driven ventilation could cool a home. The need for cool living environments is becoming more urgent. But air conditioning is […]

A Cold Tube Can Beat AC For Cooling
September 10, 2020 | Leave a Comment
University of British Columbia researchers can show how a ‘Cold Tube’ can offer relief from the summer heat without relying on air conditioning. A Cold Tube uses half the energy of conventional air conditioners and can be used outdoors or indoors. Many people beat the summer heat by cranking the air conditioning. However, air conditioners […]

University at Buffalo engineers have designed a new system to help cool buildings in crowded metropolitan areas without consuming electricity, an important innovation as cities work to adapt to climate change. The system consists of an inexpensive polymer/aluminum film that’s installed inside a box at the bottom of a specially designed solar ‘shelter.’ The film […]

University of Zurich physicists have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. If you put a teapot of boiling water on the kitchen table, it will gradually […]

New Technology For Air Conditioning
January 11, 2018 | 39 Comments
National University of Singapore researchers have pioneered a new water-based air-conditioning system that cools air to as low as 18º C (64.4º F) without using energy-intensive compressors and environmentally harmful chemical refrigerants. This disruptive type of technology could potentially replace the century-old air-cooling principle that is still being used in our modern-day air-conditioners. Suitable for […]
