What's the most efficient way to get around? Planes might burn a lot of fuel, but they also are filled with people, making each gallon go a lot farther. How does that stack up against trains, buses, cars, or the gasoline equivalent of eating a burger and hopping on your bike? The answer may surprise you. In our latest Transparency, GOOD looks at what form of transportation gets the most bang per gallon on a 350 mile trip.A collaboration between GOOD and Robert A. Di Ieso, Jr.Sources: Amtrak; Calorielab.com; Boeing; U.S. Department of Energy; U.S. Environmental Protection Agency Correction: There was a typo in the original piece, indicating that a motor coach gets .02 gallons per mile, rather than .2 GPM.
