In 1987, a newspaper ad caught the eye of a physics professor in Sydney. It was a call to adventure: build a car powered only by the sun and race it 3,000 kilometers across the Australian Outback. That professor was John Storey— and nearly four decades later, Storey is still at the heart of the Bridgestone World Solar Challenge.

Every two years, innovative young minds from around the world gather in Australia for a race unlike any other. The Bridgestone World Solar Challenge isn’t about speed—it’s about pushing the boundaries of what’s possible with solar energy, power electronics, and human ingenuity.
