The world’s largest particle accelerator now has an important new mission: heating thousands of homes. The Large Hadron Collider at CERN has begun to funnel the waste heat from its cooling system to a new residential and commercial area in the nearby French town of Ferney-Voltaire, with the new linkup expected to be able to heat several thousand homes at once.



This thing has been running for over 15 years and they just figured out they could use the waste heat?
It’s not really the same thing today as it was 15 years ago. It also hasn’t been running continuously that whole time. They regularly stop experimenting to build new extensions onto it.
I visited the LHC back in 2019 and at the time they were expanding it even then.
I doubt you can answer but did it just become economically viable?
I’d bet it was viable earlier and someone just figured this out.
Makes me wonder recycling the heat from AI data centers.
Datacenter heat is actually a very good source for local heating networks and a lot of European countries either already mandate to consider it when feasible, have introduced legislation that will make it mandatory over the next years or are at least supporting it financially.
It’s actually fairly common to do so for a long time here - from waste incineration, steel mils, nuclear plants, etc.
Personally I heat my office from my server rack and my old job did heat one of their office buildings from the heat generated by the data center in the basement. (And funny enough also did partially cool it from that source)
I’m in the US so this is not a priority for the current admin.
I guess someone has to finance the infrastructure to connect towns, might be some new ecological regulations that pushed this
Better late than never
