NOVELTY - The chemical processing method comprises extracting energy from an airstream passing a moving transport platform, providing the energy to a thermochemical reactor (1000) carried by the transport platform, receiving a donor substance at the thermochemical reactor, dissociating the donor substance into a first constituent and a second constituent in a non-combustion reaction, and preserving a cargo carried by the transport platform using the first and/or second constituents. The preserving step includes directing the constituent to a refrigerator (1083).    USE - The chemical processing method is useful for reducing and/or harvesting drag energy from transport vehicles such as freight hauling trucks, trains and cars.    ADVANTAGE - The chemical processing method is capable of reducing and/or harvesting drag energy from vehicles, thus improving over all vehicle efficiency and/or vehicle safety, reducing maintenance and/or cost of fuel, reducing or eliminating overheated and/or failed friction brakes, skidding and braking or acceleration because of traction loss due to snow impedance, water film and snow-ice produced by tire compression and compaction, and/or reducing or eliminating snow, ice and/or mud accumulations on the surfaces of vehicles.    DETAILED DESCRIPTION - The chemical processing method comprises extracting energy from an airstream passing a moving transport platform, providing the energy to a thermochemical reactor (1000) carried by the transport platform, receiving a donor substance at the thermochemical reactor, dissociating the donor substance into a first constituent and a second constituent in a non-combustion reaction, and preserving a cargo carried by the transport platform using the first and/or second constituents. The preserving step includes directing the constituent to a refrigerator (1083), and operating the refrigerator to cool the cargo. The step of directing the constituent to the refrigerator includes recharging a refrigerant carried by the refrigerator with the constituent. The preserving step further includes directing the constituent into a payload volume of the transport platform to cool the payload volume, discouraging pests by directing the constituent into the payload volume of the transport platform. The cargo includes fish and/or meat. The method further comprises directing the first and second constituents to a manifold (1085), braking the transport platform, and transferring energy resulting from braking the transport platform to the thermochemical reactor to facilitate the non-combustion reaction. The cargo is preserved by operating the manifold. The transport platform includes an over- the-road truck. INDEPENDENT CLAIMS are included for:    (1) a reactor system;    (2) a method for braking a vehicle; and    (3) a transport system.
