Datafarm: low-carbon energy for data centers

Datafarm

The start-up Datafarm proposes an energy solution for low-carbon digital technology. Within a circular economy system, it powers data centers with energy produced through methanization, by installing them directly on cattle farms.   When you hear about clean energy, cow dung probably isn’t the first thing that comes to mind. …

Astrid: a nuclear project goes up in smoke

ASTRID project

The abandonment of the Astrid project marks a turning point for France’s nuclear industry. The planned nuclear reactor was supposed to be “safer, more efficient and more sustainable”, but therefore required significant funding. Stéphanie Tillement, a researcher at IMT Atlantique, has studied how Fukushima impacted the nuclear industry. Her work …

Unéole on our roofs

Unéole

We know how to use wind to produce electricity, but large three-bladed turbines do not have their place in urban environments. The start-up Unéole has therefore developed a wind turbine that is suitable for cities, as well as other environments. It also offers a customized assessment of the most efficient …

Fukushima: 8 years on, what has changed in France?

Fukushima was the most devastating nuclear disaster since Chernobyl. The 1986 disaster led to radical changes in international nuclear governance, but has the Japanese catastrophe had the same effect? This is what the AGORAS project is trying to find out. IMT Atlantique, the IRSN, Mines ParisTech, Orano and SciencesPo are …

Optics as a key to understanding rogue waves

vagues scélérates, rogue waves

Rogue waves are powerful waves that erupt suddenly. They are rare, but destructive. Above all, they are unpredictable. Surprisingly, researchers have been able to better understand these fascinating waves by studying similar phenomena in fiber optic lasers.   Before scientists began measuring and observing them, rogue waves had long been …

KM3NeT: Searching the Depths of the Sea for Elusive Neutrinos

KM3Net

The sun alone produces more than 64 billion neutrinos per second and per cm2 that pass right through the Earth. These elementary particles of matter are everywhere, yet they remain almost entirely elusive. The key word is almost… The European infrastructure KM3NeT, currently being installed in the depths of the …
