I’ll be talking about the very serious helium shortage that is looming (actually, it’s already upon us) and risks crippling semiconductor chip production and diagnostic instruments like MRI scanners, not to mention low temperature science.. It’s maddening because we’ve known that helium is very limited but it’s cheap so no one recovers it. It’ll be on BBC World Service Newshour around 13:45 BST.#elements #chemistry #economics #profligacy
