Abstract: An energy harvesting and harnessing system is mobile and can store energy when the system is not in motion for later use in powering the mobile transport refrigeration unit (TRU) or truck mounted refrigeration units eliminating unnecessary use of the diesel motor on the refrigeration unit. There may be an interface plug between a power generation unit and the cab to power the climate controls and creature comforts in the cab of the truck while parked, thus eliminating unnecessary idling.
