Abstract
An environmental control unit for use with a transport container is provided. The environmental control unit includes: a thermoelectric device; a fan to blow air across the thermoelectric device; a cooling passage configured to receive the air blown across the thermoelectric device and convey the air to a compartment of a transport container when the transport container is removably connected to the environmental control unit; a controller in electronic communication with the thermoelectric device and the fan; a battery configured to power the environmental control unit; and one or more piezoelectric devices configured to generate electrical power to charge the battery, wherein each of the one or more piezoelectric devices is electrically connected to the battery.
