  • Renewable energy flashlight
    Patent number: 7404651
    Abstract: A renewable energy flashlight includes a flashlight housing, a light emitter carried by the housing, and a power source carried by the housing and powering the light emitter. The power source includes a charging magnet, at least one induction coil, and first and second repulsion members, all carried by the housing. The housing is configured to allow movement of the charging magnet between first and second positions within the housing. The induction coil carried is configured to allow movement of the charging magnet therethrough, thereby inducing current through the induction coil. Each repulsion member includes an elastic rebounding material reflexively seeded with at least one internal magnet. The first repulsion member is secured at the first position within the housing in polar opposition to the charging magnet. The second repulsion member secured at the second position within the housing in polar opposition to the charging magnet.
    Type: Grant
