An ultra-tiny, ultra-short video pushed to the limits of what can be uploaded to YouTube. There’s nothing there. But in fact, there is a “grain”-like video. That is “Uritsubu - YouTube.”

Winner of the New Technology Promotion Watanabe Memorial Foundation Chairman’s Award at the 67th Science and Technology Film Festival (2026). This documentary follows the engineers who stepped forward to take on the challenge of realizing an engine-powered vehicle that emits no CO₂—and even reduces it—while believing in a future where they can take pride in driving cars with internal combustion engines. It delves into the public demonstration in the Super Taikyu series using a vehicle equipped with Mazda Mobile Carbon Capture, a CO₂ capture device, as well as the engineers’ determination, convictions, and the driving force behind their challenge to make it a reality.
