According to @ai_darpa, China has begun mass production of nuclear batteries smaller than a coin, delivering continuous power for decades without the need for charging, sunlight, or maintenance (source: @ai_darpa, 2025-12-12). The initial model provides 100 microwatts, with a 1-watt version in development for use in drones and smartphones. This breakthrough holds significant implications for AI-powered IoT devices, autonomous sensors, and smart devices, enabling unprecedented uptime and reducing operational costs. Businesses in AI hardware, smart robotics, and remote monitoring can leverage these advancements to create maintenance-free, always-on solutions for industrial automation, logistics, and smart city infrastructure.
