The document compares the costs of grooming 900 acres of ski slopes per night using either 11 traditional cats or 15 cats, with some upgraded with an EcoGroomer system. It finds that using 11 cats including 4 upgraded with EcoGroomer would save $105,450-$147,630 per year in fuel and other costs compared to using all traditional cats. Over 5 years, the savings would be up to $2.95 million. The document outlines steps to further develop and test the EcoGroomer system between late 2010 and winter 2011.
