A sustainable greenhouse maintained by Professor of Economics Michael Donihue and his wife, Susan MacKenzie, a Jan Plan instructor, at their home was featured on the Growing Spaces website. Their dome, which they’ve maintained for seven years, allows them to grow produce year-round, and it serves as an educational tool for Colby students. 

“Donihue teaches a class of his invention called Joules to Dollars with fellow professor (Dr. Frank and Theodora Miselis Professor of Chemistry) Whitney King. The course is ‘a scientific approach to the economics of sustainable energy systems.’ In an average semester, 10-20 kids use Michael’s Growing Dome as a bioshelter lab. They “specifically keep track of energy consumption, temperature, humidity, and light levels inside the shelter. Outside the shelter, they measure temperature, rainfall, light levels, barometric pressure, and wind speed and direction.”
