A big net savings

Cool story in today’s Boston Globe:

Tom McHale is a hero at the MBTA, not for saving lives, but for saving a lot of money thanks to steak tips, electrical tape, and a 5-cent, fine-mesh hair cap.

He figured out that a hair cap fit perfectly on the air intake for MBTA subway train motors. Snow is often sucked up by a moving train, melts and then refreezes blocking the intake, causing the train’s motors to fail. Repairs are incredibly expensive. The hair cap lets the air in but keeps the snow out. A box of 1,000 hair caps cost $50. MBTA officials estimate that his solution will save the agency $126,000 in repairs in an average year.

McHale is being promoted and will be honored by the T today for his idea. What a fine hack!
