Does it come with an optional perpetual motion machine? This four-passenger car's solar cells allegedly "generate more electricity on average than the car uses"

Student team unveils world’s first solar-powered family car

The Solar Team Eindhoven (STE) of TU/e presented the world’s first solar-powered family car today. ‘Stella’ is the first ‘energy-positive car’ with room for four people, a trunk, intuitive steering and a range of 600 kilometers. This is the car being entered by the student team in the Cruiser class of the World Solar Challenge that starts in Australia in October 2013.

The solar cells of ‘Stella’ - Latin for star – generate more electricity on average than the car uses and that means the surplus electricity can be returned to the power grid, thereby making the car ‘energy-positive’.
