A refrigerator running on sun and water.
A student of MIT in Boston has developed The Evaptainers, an electricity-free and mobile fridge, using evaporative cooling technology.
Radiative cooling: protecting ice from melting under sunlight
Researchers have developed a biodegradable film made of cellulose acetate which, thanks to its radiative cooling properties, effectively protects ice subjected to solar radiation from melting, with possible...
Cool like a butterfly wing
New study demonstrates that butterfly wings contain a network of living cells with specific thermodynamic and thermoregulatory properties. Butterfly wings cool down as a result of low solar absorption combined with efficient radiative heat...
White paint reduces air conditioning demand
A team of researchers has developed a radiative cooling paint that keeps surfaces more than 1.7 °C cooler than their ambient surroundings (at noon).
Radiative cooling: smart materials to switch from heating to cooling
Researchers have developed a radiative thermal management device, composed of several layers of reflective/absorbent materials, capable of switching between heating and cooling...
How to reuse the condensate water from air conditioners?
Review of the different uses of the condensate water rejected by air conditioners.
Radiative cooling coatings that can adapt to the seasons
A novel material can be used as a coating on building’s rooftops or windows to provide radiative cooling in the summer without overcooling in the colder months.
The Montreal Protocol pays off
According to a recent UNEP report, the ozone layer is recovering. It could be restored to its initial state from 2040, except in Antarctica and the Arctic.
Passive cooling by combining evaporation, radiation and insulation
ICER, a new passive cooling technique, can extend food shelf life by 40% in humid climates and 200% in dry climates with low water-refilling frequences.
