Solar Decathlon 2011: Middlebury College’s Self-Reliance House

Posted on March 1, 2011 by Richard Defendorf in 2011 Solar Decathlon

The individualist spirit that became Ralph Waldo Emerson’s calling card found a home at the 2011 Solar Decathlon when the team representing Middlebury College decided to name its entry Self-Reliance, after the title of one of Emerson’s most famous essays on the virtues and challenges of independent thought, originality, and action.
