With the scream of a circular saw cutting metal as a soundtrack, Tom Brussard led me around to the back of a refrigerated truck that was parked in a vast Medford garage. A team of three workers was installing a new system in the back of the truck that would allow the driver to easily move around a set of plastic curtains that keep in the cold.

As the driver made deliveries of fresh produce, emptying the truck, he’d be able to slide the curtains forward, shrinking the space that needed to be kept cold. The result: “The refrigeration unit on the truck works less, and less run-time not only means the truck uses less diesel fuel, but also that there’s less maintenance on the unit itself,” Brussard says.
