Abstract: The method of effluent disposal thermal energy from an engine to vaporize the effluent. The engine drives an air compressor, which produces compressed air and an effluent byproduct. Both the thermal energy from the engine and the effluent from the air compressor communicate with a heat exchanger. After reaching an appropriate temperature, the heat exchanger transfer thermal energy to the effluent thereby vaporizing at least a portion of the effluent.

Abstract: A running gear for a wagon comprises a cantilever extending away from one end of the wagon, a socket coupled to the cantilever proximate a distal end of the cantilever, a kingpin that rotatably engages the socket about a steering axis of rotation, at least one steering axle coupled to the kingpin for rotatably retaining at least one steering wheel to allow each steering wheel to swivel about the steering axis of rotation and a draw bar coupled to each steering axle to tow and steer the wagon.
