Scientists from the Kurchatov Institute have introduced a battery based on nuclear isotopes that can operate for up to 10 years without recharging. The device can be used in sensors, medical implants, and monitoring systems in hard-to-reach places.

Editorial comment: 10 years without recharging — like a perpetual motion machine, but real. True, it's not clear how to dispose of it if it does break. But perhaps by then we'll be living on Mars and the issue will resolve itself. In the meantime — we'll put the battery in a sensor in the north and forget about it for a decade. A dream, not a technology. The editorial opinion may not coincide with the position of the authors and other experts.
