A human powered electricity generator includes a suspension system including a compliant mechanism that permits a first portion of the suspension system to be displaced relative to a second portion of the suspension system as a result an application of force to the first or second portions of the suspension system. A generator converts the mechanical displacement of the first portion of the suspension system with respect to the second portion of the suspension system into electrical energy and stores the electrical energy in an energy storage device. Displacement means, such as a handle or a seat, is connected to either the first portion or the second portion of the suspension system to enable a user to manually displace the first portion of the suspension system with respect to the second portion of the suspension system so as to increase the efficiency of the energy generation. The stroke distance may be increased using a turnbuckle adjuster or an adjustment device that adjusts the length of the holder that holds the compliant mechanism in place. Extendible feet attached to one of the first and second portions of the suspension system also may be used to increase the mechanical displacement distance. The electricity generating device of the invention enables a user to produce electricity by hand pumping even when the user is not walking.

An improved railroad frog, and method incorporating the same, for facilitating the intersection of rail lines in a more efficient, effective, and durable manner. In one aspect the invention is a railroad frog apparatus comprising: a body having flangeways that intersect; and at least one connection plug extending from the body for connecting to a running rail; the at least one connection plug having a cross-sectional profile that is substantially identical to a cross-sectional profile of the running rail. In another aspect the invention is a railroad frog apparatus having at least one flangeway having a floor with a convex surface formed of at least one arc. Such geometric surface shape of the floor reduces rail batter, undesirable vibration, and damage to train wheels.
