1. A renewable energy flashlight comprising:

  • a. a main housing with an opening at one end leading into an interior chamber and a closed end, b. a cylindrical tubular carriage sized to fit and be inserted within the main housing interior chamber, said carriage defining an internal transverse chamber with a first end, and a second end, c. support structure associated with the main housing and/or tubular carriage for holding electrical components proximate the opening of the main housing, d. a charging magnet having a magnetic field mounted within the internal transverse chamber structured to hold the charging magnet for lateral transversing movement between the first end and second end of the carriage unit, e. a pair of elastomagnetic repulsion members, each comprised of an elastic rebounding material into which is reflexively seeded with at least one internal magnet, one of the pair mounted to the first end of the carriage unit in polar opposition to the charging magnet and the other mounted to the second end of the carriage unit in polar opposition to the charging magnet so that the rebound material is first compressed until the charging magnet is slowed in the proximity of the seeded magnet and then rebounded elastically and magnetically assist in rebounding the charging magnet between the elastomagnetic repulsion members, f. at least one induction coil wrapped around the tubular carriage such that the charging magnet may pass completely through the induction coil during each transverse pass to induce current through the induction coil, g. a capacitor operably associated with the induction coil for storage of electric current generated by the induction coil, h. a light emitting diode mounted on the structure, i. a convex magnifying lens covering and sealing the opening of the housing, and j. circuitry mounted on the support structure and connected to the capacitor, the light emitting diode and the induction coil to selectively charge the capacitor in one mode and discharge the capacitor to power the diode in the other mode.
