In some embodiments, a powered trailer is provided having a chassis, a fixation structure for fixing the chassis to a target vehicle to be pushed, a drive mechanism for applying motive force to the chassis, an energy source for powering the drive mechanism, and a controller for controlling the application of motive force to the chassis by the drive mechanism. The drive mechanism is actuated by the controller to push the target vehicle.

A pneumatic drive system for a motorized vehicle includes an air compressor that is operable to couple with a main drive shaft of the motorized vehicle so as to activate the air compressor and generate pressurized air during a braking operation of the motorized vehicle, an accumulator that is operable to receive and store pressurized air from the air compressor during the braking operation, and a pneumatic motor that receives the pressurized air from the accumulator to activate the pneumatic motor. During activation, the pneumatic motor provides energy to the main drive shaft during an acceleration operation of the motorized vehicle.

A compressor, an intercooler, and a fuel cell stack are housed in a housing compartment. The compressor and the intercooler are connected with each other by upstream side piping, and the intercooler and the fuel cell stack are connected with each other by downstream side piping. The upstream side piping is formed from upstream side first and second pipe parts, and the downstream side piping is formed from downstream side first and second pipe parts. Movement of the compressor and fuel cell stack relative to the intercooler at the time of a heavy collision of the vehicle causes disconnection of the upstream side first and second pipe parts and disconnection of the downstream side first and second pipe parts, to thereby cause communication of the upstream side piping and the downstream side piping with an internal space of the housing compartment.

A capturing wind power system is described that includes a plurality of pipes that extend along the vehicle length and curve towards the rear end of the vehicle. The pipes capture air to help propel the vehicle forward, improving fuel mileage. A cover may be used encase the pipes and allow a rear segment of the pipes to be removed when opening a door at the rear end of the vehicle.
