'It's very counterintuitive': The quantum batteries that upend the rules of charging
Summary
BBC reports on CSIRO's demonstration of a quantum battery prototype that charges faster as the battery grows, thanks to quantum superabsorption. The device operates at room temperature and could power quantum devices or mobile devices in the future, but current energy storage is very small and the effect is fragile in real-world conditions. The piece discusses competing approaches, skepticism, and the roadmap to practical use.
