DARPA plans 30-year endurance nuclear waste batteries to power next-gen drones, says report — project SYMPHONEE aims to harvest Strontium-90 to power persistent military drones

DARPA is developing a groundbreaking project called SYMPHONEE, which aims to create nuclear waste-powered batteries that could last for up to 30 years, providing a virtually inexhaustible energy source for next-generation military drones. By harnessing the radioactive decay of Strontium-90, these radiovoltaic batteries could enable drones to operate continuously without the need for frequent recharging or maintenance. This innovation could significantly enhance the operational capabilities and endurance of military drones, offering long-term surveillance and reconnaissance advantages.
