  1. Key quote from Prof. Lu: “I really hate that we use 200-year-old technology for testing, which is not very accurate and not consistent,” she said. “Because of it, we make so many poor decisions and waste a lot of money.”

    The reliance on centuries-old technologies is the reason we face massive challenges in dealing with climate change and other problems: e.g., the reliance on coal, the internal-combustion engine, etc.

    Bravo to Prof. Lu and her team for their innovative thinking.

  2. This is astounding and could be a game changer. But concrete is expected to last far longer than the 30-year useful life of the sensors so that seems to be a significant limitation.
