Industral designer Eric Botzen of Botzen Design has a plan to revitalize both Detroit and the battery of that portable electronic device in your pocket. It’s called the Solar Vox Ultra, and it recently made its debut at the Maker Faire in Motor City, USA.

The 2.0 version of the original Solar Vox, this solar charger eschews the clunky, bulky design of the original for a more compact, portable profile. Petal-like panels unfold to reveal the solar panel in the center, effectively chanelling the sun’s rays to the sweet spot where they can generate energy for your device.

The Solar Vox Ultra was designed for a long life span — 10+ years — and charges portables via a basic USB connector, negating the need for different charging tips (providing your device charges via USB). It was also designed to be manufactured in Detroit, and Botzen Design is currently seeking angel funding (preferably Michigan-based) to get this project off the ground
