Buckeye Bullet is heading down towards the mountain end to prep for a run. I talked with one of the crew guys this morning -- they use about 300 pounds of ice per run. It cools the fuel cell and the inverter. The motors need to stay cool -- start at ambient and get up to about 80C by the end of a run. 100C is where the motor starts being damaged. They don't have a cooling system, although they've kind of built a cool-suit device to wrap the motor during the turnaround.
