A power generation apparatus comprises : at least one magnet 30 mounted on an axle 32 that rolls along a guide or track 12 comprising an endless loop; and means to incline the track. Rotation of the magnets about the axle induces electrical current in pickups such as coils 40 that may be positioned above and below the track. The track can be banked and have equal length rails or circular with tapered axles (fig 4, 132). The magnets can be permanent and comprise a rare-earth, a metallic, a composite or a nanostructured magnet. There can be plural magnets and axles that are interconnected to form a train. The pickup coils may be in a stator (fig 7, 210) surrounding the magnets which is prevented from rotating by trailing arms and hooks (fig 7, 214 and 216) that slide along the track and planet gears (fig 8, 244) may increase the magnets velocity. The track can be tilted about a multi-axis fulcrum (fig 3, 160) by a crank, lever, a hydraulic or pneumatic piston, or renewable energy such as wind or waves. Tracks may be side-by-side in pairs (fig 5) and/or one above the other (fig 6).
