What is renewable energy storage?

The storage of green energy is an issue which concerns many sectors, whether for energy transition or for supplying power to connected objects using batteries. Thierry Djenizian, a researcher at Mines Saint-Étienne, explains the main problems to us, focusing in particular on how electrochemical storage systems work.   Why is the storage of renewable sources […]

New Caledonia: a mine challenging democracy

When an industrial mining complex wanted to release a pollutant into their lagoon in the late 1990s, the inhabitants of the southern province of Grande Terre took action. In their fight against the environmental and cultural danger, the citizens found it difficult to make their voices heard. Today, almost 20 years have passed since the […]

Will we soon be able to control machines with simple gestures?

The “Silense” European project launched in May 2017 is aimed at redefining the way we interact with machines. By using ultrasound technology similar to sonar, the researchers and industrialists participating in this collaboration have chosen to focus on 3D motion sensing technology. This technology could allow us to control our smartphone or house with simple […]

Fine particulate pollution: can we trust microsensor readings?

Nathalie Redon, IMT Lille Douai – Institut Mines-Télécom Last May, Paris City Hall launched “Pollutrack”: a fleet of micro sensors placed on the roofs of vehicles traveling throughout the capital to measure the amount of fine particles present in the air in real-time. A year before, Rennes proposed that residents participate in assessing the air quality via individual […]

Air quality: several approaches to modeling the invisible

The theme day on air quality modeling (organized by FIMEA and IMT Lille Douai) on June 8 provided an opportunity for researchers in this field to exchange on existing methods. Modeling makes it possible to identify the link between pollution sources and receptors. These models help provide an understanding of atmospheric processes and air pollution prevention. […]
