Cross-sector team says device, which marks significant step in long-life power sources, was developed without foreign tech or parts.

Chinese researchers have developed a new-generation nuclear battery that far surpasses its predecessor and marks a major step in long-life power sources, according to the team. Northwest Normal University, in collaboration with Chinese tech firm Gansu Zhulong Technology, unveiled a carbon‑14 nuclear battery and silicon carbide (SiC) transducer on Monday, saying the equipment was developed without any foreign technology or parts. The Qianjiyuan Tianshu battery is a major upgrade from the team’s…

    FYI, some comparisons:

    • That’s about how much an efficient CMOS clock (like on a PC motherboard) uses. LCD watches and calculators start at about twice as much.
    • A device with such energy use would deplete a CR2032 cell in 80 years if one could last this long.
    • With typical indoor illumination, photodiodes of about 5x5 mm total area are required to supply 1 μW.

    This battery is about 4×4×1 cm.
