The year 2010 marked the 20th anniversary of New Mexico State University’s International Environmental Design Contest, created to bring innovative technologies to the marketplace. This year the Contest was held at the Pan American Center here on New Mexico State University campus. More than 5,000 students have participated in the engineering challenge focused on evolving proprietary technologies covering complex environmental challenges related to energy, water and overall sustainability. All the challengers in Las Cruces this week presented a poster and oral presentation, a written report and a bench-scale demonstration to a subset of about 40 judges from industry, academia and government. Teams have the chance to win cash prizes, academic and professional recognition, as well as forming lifelong bonds with other participants.
