A guided missile is directed to railroad tracks, is buried a particular distance, such as five (5) feet, below the tracks upon reaching the tracks and is covered by rocks in the railroad bed as it moves the particular distance below the tracks. The guided missile detonates when the train approaches on the tracks within a particular distance from the guided missile on the tracks. The train then becomes derailed. The guided missile has a housing which is made from a strong metal and which is relatively thick. Preferably the metal is steel and has a thickness of about 0.2'. A nose cone having a blunt configuration is disposed on the housing at the front end of the housing and is made from a material which passes signals into and out of the housing. The material is compressible (e.g. fiberglass, a ceramic or a glass) to become flattened when the missile strikes the ground. A bulkhead preferably having a greater thickness than the housing is disposed in the housing at an intermediate position along the housing length. The bulkhead may be made from the same material as the housing. A seeker including an antenna is disposed in the housing between the nose cone and the bulkhead to transmit signals to the tracks and receive information from the tracks. A warhead is disposed within the housing on the opposite side of the bulkhead from the nose cone. A fuse is disposed within the housing at the rear of the housing to detonate the warhead when the train approaches the missile on the tracks.

A vertical axis wind-driven rotor which combines effective utilization of the energy in a strong wind with maintenance of effective torque at low wind speeds. In one embodiment, the rotor has a reservoir of liquid located near its base. A plurality of tubes radiate outwardly from the reservoir along the base, then rise upwardly along the outer edges of the rotor vanes. In another embodiment, a Savonius type rotor is modified so that the vanes are hinged, and the trailing edge of each vane weighted, whereby in a wind the rotor starts in a fully open condition and automatically feathers itself at high wind speeds.
