A strange headline. None of this is 'weird’. Some of it might not scale (especially the human element) but weird? Does the Gruaniad employ anyone with even a knowledge of science and engineering (I’m not asking for a degree)? Clearly in its references this has been written from their ‘business column’ https://www.theguardian.com/environment/2026/jul/19/molten-salt-human-sweat-weird-batteries-store-renewable-energy #renewables #storage #electricity
