Abstract: A mini-turbine includes a hollow inner cylinder adapted to connect to a fluid source; a rotor disposed in and rotatably connected to the inner cylinder, the rotor comprising blades and an enclosed permanent magnet for producing a magnetic field; a winding mounted around the inner cylinder and being about flush with the rotor; a hollow outer cylinder mounted around the inner cylinder in a spaced fashion; and a nozzle disposed at a top opening of the inner cylinder and above the rotor. In one embodiment, pressurized water from a faucet may impinge upon the blades to rotate the rotor after passing the nozzle so that the rotor may cut lines of magnetic flux in the magnetic field to generate an induced AC voltage in the winding.
