AI-designed heat pumps consume less energy
AI-designed heat pumps consume less energy
Researchers at EPFL have developed a method that uses artificial intelligence to design next-generation heat-pump compressors. Their method can cut the pumps' power requirement by around 25%. In Switzerland, 50-60% of new homes are equipped with heat pumps. These systems draw in thermal energy from the surrounding environment - such as from the ground, air, or a nearby lake or river - and turn it into heat for buildings.

Improving urban flood prediction
Improving urban flood prediction
Heavy rainfall can cause flash floods in urban areas. While data from flood events is required to model such phenomena, water levels and discharges are not routinely measured above ground. Eawag now plans to make use of widely available images and videos to estimate these values. We are all familiar with the chaotic scenes caused by torrential rain in towns - roads turned into raging rivers and sewers overflowing, unable to cope with the volume of water running off streets, squares and rooftops.

Bridges get a quick check-up
Bridges get a quick check-up
Engineers have developed a new imaging technique that lets them see the insides of massive concrete bridges. Much like a sonogram, this technique provides quick, easy-to-interpret images, so that the health of these expensive structures can be assessed and monitored. The patient weighs several tons and is hundreds of meters long.
