Sunlit Computers with Peter Veto and Liliana Lettier of Pixun

What if your computer screen could heal you instead of harming you?In this episode of Sunlight Matters, we’re joined by Dr Peter Veto and Liliana Lettieri, the visionary team behind Pixun — a company pioneering solar-powered, full-spectrum displays that use real sunlight instead of artificial backlighting.Peter and Liliana share their personal journeys with light sensitivity, screen-induced insomnia, and EMF-related health issues, and how those struggles inspired them to engineer a radically new type of screen — one that brings the entire solar spectrum indoors using fiber  optics and rooftop solar collectors.We dive into:Why most screens today are making us tired, sick, and unfocusedThe science behind sunlight exposure, blue light toxicity, and circadian disruptionHow Pixun’s screens deliver natural light through displays, supporting everything from sleep health to vision and cellular functionReal-world applications for urban living, real estate sun studies, architecture, and workspace wellnessHow tools like shadow mapping and sunlight analysis can optimize solar collector placement for homes and commercial buildingsWhether you’re a parent worried about your child’s screen time, an architect exploring better building orientation, or a company looking to improve employee wellness through sunlight-optimized tech — this episode will change the way you think about screens forever.Sunlight Matters is a podcast exploring the role of the Sun in human health, architecture, cities, and everyday life.Through conversations with scientists, architects, and technologists, the series examines how natural light shapes our bodies, our buildings, and the way we live indoors.Hosted by Dave Wallace, Sunlight Matters asks a simple but overlooked question: what happens when we disconnect from the Sun?Because sunlight isn’t optional. It matters.Please do not forget to Like and Subscribe.
