BMW challenged students to build an EV that makes more energy than it uses. They covered it in 1,700 solar cells and it works.

TL;DR Clemson students built the Luminetta for BMW: a 1,212-lb solar EV with 1,700 cells that generates 31 miles of range daily. BMW challenged graduate students at Clemson University to build an electric vehicle that generates more energy than it consumes in a day of urban commuting. Deep Orange 17, which BMW calls the Luminetta, is a two-seat solar EV covered in more than 1,700 photovoltaic cells developed with the Fraunhofer Institute for Solar Energy Systems. It weighs 1,212 pounds and produces enough solar energy to regenerate 31 miles of range per day, more than double the 12-mile daily commute the team used as its benchmark. Lightyear promised a solar EV that could go months without charging, then went bankrupt.
