In the future pennies have become obsolete and a new type of furnace is invented that converts the mass of them directly into energy with an efficiency of 60%. How many 0.0024 kg pennies would you need to burn for the furnace to power the movement of a 531000 kg future-train for 1,000 trips along a trac with a coefficient of static friction of 0.66 for the entire 40,000 km circumference of the Earth? pennies x 1060
