Mouna Andraos was showing her Power Cart in the streets of Williamsburg (Brooklyn) yesterday, offering alternative power to passersby in need of charging their mobile phone.

The mobile unit is inspired by street vendors, knife sharpeners from India, refills of gas in Africa, fake Gucci bags in Paris and chair massages in New York, the Power Cart looks and feels like another service for the city of today. Where ever you might be in the world, hail the Power Car for a quick fix. The Power Car owner will turn the crank for you and get the electricity you need, one minute of cranking at a time. With a little help from the solar panel.
