Team gathered at Leach Theatre to witness the unveiling of Solar Miner VII.
Several members of the team, as well as a few advisiors, told the crowd about
the history of solar car racing, the team’s history, and various design changes.
After viewing the time-lapse video of construction, the team invited everyone to
the stage to see SMVII, take pictures, and ask questions. The reception by
alumni boosted the team’s faith in the new design
