  • How Janelle Lynch Sees Beyond the Image
    Mar 25 2026

    A great photograph does not always start with an idea. Sometimes the physical 'yes' forms within the body when the light hits the subject just right. ☀️

    We talk with photographer Janelle Lynch about her creative process in landscape photography, her more recent portraits, and her cyanotypes, made with a nineteenth-century cameraless technique. Janelle shares how she developed her love for the camera from her early experiences of being seen by others, why she avoids the word 'capture,' and how her images often emerge through a conversation with her subjects. We also get into her craft and the work that she does with her 8x10 view camera. 📸

    Janelle draws inspiration from various sources and incorporates practices into her routine, such as yoga, proprioception, and perceptual drawing and painting with others. One of the visuals Janelle shares with us is an eight-minute exposure taken in near darkness, which leads to a discussion of what exists even when we cannot see it. 🍃

  • Safe by Design: How Terra Innovatum’s Micro Reactors Are Changing Nuclear Energy
    Mar 20 2026

    The grid is strained, AI data centers are exploding in demand, and clean baseload is once again on the table. Alessandro Petruzzi, Co-Founder and CEO of Terra Innovatum, joins the show to talk about a different kind of nuclear power: micro modular reactors that are safe by physics, not by emergency equipment. ☢️

    Terra Innovatum has developed the Solo, a 1 megawatt electric micronuclear reactor. Alessandro discusses how 1 megawatt is physically small-scale, how the low power makes decay heat much easier to manage, and how the reactor is engineered so it cannot melt down. He also shares how the company is using existing nuclear fuel and supply chains to build the reactor, which will shorten the timeline to building the first one. 🏭

    For use cases, Alessandro shares how these nuclear reactors could supply power to AI data centers waiting on grid transmission upgrades, mining operations that need to reduce their CO2 emissions, and even provide bonus outputs that may be even more important. Microreactors can provide desalinated water to areas with water scarcity issues or produce medical radioisotopes for hospitals to treat cancer patients. ⚡

  • Almost Human: How Realbotix Is Redefining Humanoid Robots
    Mar 13 2026

    A humanoid robot that looks you in the eye, answers questions in 100+ languages, and continues to chat with you long after the camera crew has left… sounds like science fiction. Yet, this is the future that is quickly becoming the present for companies like Realbotix. In this episode, CEO and Executive Chairman Andrew Kiguel talks to us about the company behind the humanoid robots and why the talking robots of the future may be the first to populate our public spaces. 🤖

    Andrew discusses the company’s start with silicone robots meant for film. He discusses how the company began adding motors and movement to its lifelike figures without sacrificing human proportions. The importance of using robots to express facial emotions, use a friendly voice, and foster companionship when interacting with patients in hospitals and schools is discussed. 🏥

    The interview turns to the technology behind these humanoid robots. How they use embedded artificial intelligence to “see” the world around them in ways that allow them to understand their environment. Their use of plug-in power to give them longer operating times without batteries, their use of suitcase-sized robots that can travel from place to place easily, their use of various AI programs that can be downloaded and installed like an app store, and their discussions of automation and the new jobs that will be created in the future. 🦾
