Abstract: Modular smoking devices that vaporize certain materials, such as tobacco or cannabis are disclosed. The technology provides for intelligent ignition, combustion, or vaporization of given material at the appropriate temperatures that prevent generation of harmful and unwanted byproducts. According to one embodiment, the modular smoking device comprises a self-contained combustion chamber to hold the material, a combustion mechanism integrated with the self-contained combustion chamber, and an energy source, such as a rechargeable battery, to power the combustion mechanism. The combustion mechanism is configured to provide targeted combustion of the material, where the active ingredients generated upon the combustion are consumed by inhaling a smoke or vapor resulting from the combustion or vaporization.

Abstract: A railcar shove light for attachment to a railcar rear coupler, the railcar shove light incorporating a turbine; a turbine case having a compressed air input port and an air output port, the turbine being rotatably mounted within the turbine case; an electrical alternator; a rotary drive linkage interconnecting the turbine and the electrical alternator; an array of electrical light emitters; electrical wires interconnecting the electrical light emitters and the electrical alternator; a light case housing the turbine, the turbine case, the alternator, the drive linkage, and the light emitter; and incorporating a brake line connectable air conduit for supplying and driving the turbine; the light case being mounted to a support post having lower end coupler engaging pin.
