A rotary motion machine (10) and method of operation that includes at least one radially expandable piston (16) defining an inner chamber (20) having a volume that varies upon radial expansion and contraction of the piston, a core (12) defining, at least in part, a cylinder (14) in which the piston is positioned, a rotor (22) rotationally movable relative to the core and being rotated by a relatively incompressible fluid (17) driven by expansion of the piston, and at least one magnet (26) associated with the rotor that, upon rotation of the rotor, generates electricity in a cooperatively arranged coil (28). A novel fuel injector (18) atomizes and injects fuel along the length of the inner chamber. The piston can include a spiral of thin, flexible foil (50) of amorphous material having a strip (51) of a crystalline material for causing the spiral to expand after contraction. In one embodiment, the spiral has a melting temperature of about 3,200 degrees Celsius. |
