Avez-vous vu les propos de @cestrosi au sujet de la remise en liberté de @NicolasSarkozy. C’est quand m��me scandaleux qu’un élu parle d’une « injustice » à propos d’une décision de la justice ! #Sarkozy #Darmanin

I was happy to visit the #ITER site today and see the rapid progress of the tokamak assembly. This project is unique in the world and really breathtaking. Achieving fusion energy would be a great news for mankind ⁦@iterorg⁩ ⁦@CLICADARACHE

Pietro Barabaschi (#ITER's director-general) gave a great talk at the 30th #IAEA Fusion Energy Conference. First time I hear an ITER top manager addressing so openly the issues and challenges #fusionenergy @iterorg

Congrats @MikeFinkel for this excellent article on the #ITER fusion project, with amazing pictures. "Building a giant fusion machine is both a sprint and a marathon, with surprises around every corner," says Pietro Barabaschi: #fusionenergy https://t.co/jHeU8m5rhN via @NatGeo

The race is on to harness the near-infinite power of nuclear fusion—by building a star on Earth. And scientists are closer than you might think.

#ITER has recently decided to change the reactor's first wall material from beryllium (Be) to tungsten (W). This study shows that W behaves differently as compared to Be during normal operations as well as during current disruptions https://t.co/kPe3dgKW2C via @ioppublishing

The sixth module of ITER's central solenoid has arrived from the US at Cadarache in #Provence. This huge magnet (17 m tall and 4 m wide) weighing 1000 tonnes is a key component of the "magnetic cage" that will imprison ITER's plasma #fusionenergy #ITER

We attended today the “ITER safety day”. @CLICADARACHE is an independent association that aims to inform the public about the three #nuclear projects in #Provence (ITER, CEA and Gammaster) #ITER @CEACadarache @iterorg

The EU can’t kick Russia out of the #ITER fusion project, said EU commissioner Dan Jørgensen as the ITER agreement does not provide for this possibility. ITER involves 7 members: EU, China, India, Japan, Korea, Russia, and the US #fusionenergy @Euractiv https://t.co/xsQIWvjJnc

Access to funding remains a major issue for fusion, says @Fusion_Industry report. The fusion industry raised USD 2.64 billion in funding in the 12 months to July 2025. Total funding for the 53 fusion companies surveyed has reached a cumulative USD 9.766 billion #fusionenergy

A bit more than 20 years ago, the ITER members decided to build #ITER in France (during a meeting of the ITER Council in Moscow on 28 June 2005). Read the full story here: https://t.co/2Z2le8vpsK. The photo shows the ITER platform in March 2009. #fusionenergy #cadarache

Investors are pouring billions into fusion companies, encouraged by breakthroughs that they contend have put a sustained reaction tantalizingly within reach.
