Low-cost cold storage in Kenya using evaporative cooling
A team of researchers from the Massachusetts Institute of Technology (MIT) and the University of Nairobi are designing affordable off-grid cold storage units for perishable crops in Kenya, using evaporative...
Higher AC setting temperatures to reduce thermal discomfort and energy demand in warm countries
Using data from four cities in India, Philippines, and Thailand, a recent study found that occupants experience thermal discomfort from unnecessarily low air conditioning (AC) temperature settings. Warmer indoor...
The race to design individual cooling devices
Cooling individuals would be less energy-consuming and a lot cheaper than cooling entire buildings. Based on that principle, companies, start-ups, and researchers are racing to build wearable devices that can act like mini air-conditioning...
