Hats off to Seventh Generation President & CEO Jeffery Hollender, who recently converted his 1983 Mercedes diesel station wagon to run on pure vegetable oil. We mentioned it awhile back, and it's really good to see the head of one of the more sustainable companies out there walking the walk. Now that he's made the conversion, Hollender's car is just like his products: no petroleum additives necessary. He also calculates that, at 30 mpg, his car emits about 25% of the CO2 of a Prius, and that each person that switches from a car that burns gasoline and gets 22 mpg to one that run directly on vegetable oil would save 550 gallons of gasoline, and avoid releasing 6,500 pounds (3.2 tons) of carbon dioxide into the air every year! Kudos to Jeffrey for making such a sustainable lifestyle choice; he says he feels proud each time he climbs behind the wheel, and we think he should, too. His conversion was done by Gilead Garage in Randolph, Vermont. [The Inspired Protagonist]
