The Navitas is a bike trailer that generates its own power using the sun and wind. Designed by Paul Smith, a student at University of Derby in England, the trailer has a rear wheel that splits three ways to become a vertical axis turbine. There is also a compact solar panel to help to provide a charge to the onboard 24V battery. The battery provides power through a 12V cigarette lighter socket and a USB hub. I’m not sure how practical a wind turbine the wheel would make, but the idea is interesting nonetheless.
“It’s purely for the cyclist adventurer who likes to pedal around the country but also likes a bit of creature comfort,” says Paul.
