Segun Oyeyiola built a wind- and solar-powered Beetle

SolarBeetle2Segun Oyeyiola has managed to make something extraordinary. The engineering senior at Nigeria’s Obagemi Awolowo University spent a year retrofitting a Volkswagen Beetle into a wind and solar-powered car partially made of free scrap parts donated by friends and family. Everything else cost under $6,000.

Dr. John Preston, chair of McMaster University’s engineering physics department and faculty advisor to the school’s solar car team, says he’s never seen anything like Oyeyiola’s contraption, which also comes with a GPS app that monitors car health. “If you could find a way to use both wind and solar in the same vehicle, that would be a marvelous thing,” he said. “Using wind and solar means you wouldn’t have to drive just during daylight hours. If he has figured a way to do it, that would be quite remarkable.”

Not only did Oyeyiola install a giant solar panel on top of the Beetle; he also inserted a wind turbine under the hood. As Preston explains, that allows air to flow into the grill while the car is moving, subsequently turning the turbine’s rotors and charging the battery at the back of the car. Oyeyiola also built a strong suspension system to deal with the weight of the battery itself.

It’s not perfect. The battery takes four to five hours to charge, but Oyeyiola says he’s working on that. The biggest challenges, he says, came from finding the best materials to use, and people telling him he was wasting his time.

That last part doesn’t seem like it’ll stop Oyeyiola, who wants to create solar and wind-powered cars that take advantage of hot, sunny Nigerian weather. When I ask him what will happen to the car after he finishes his last finals on May 15, his answer is simple, straightforward: “Keep improving on it, until it becomes Nigeria’s future car.”
