The green laser is a self-driven generator conceived from Faraday’s law which transforms power into a laser beam. This beam can serve as a target or guide in ocean and mountain rescue efforts, thus providing victims with necessary power for survival. When, for example, hung on a backpack, the system is recharged due to the vertical movement produced by the walking person carrying the backpack. In case of low power, manual recharge is available. The high identification rate of the 10mW green laser beam reaches as high as 3,000 meters. It is water resistant down to a depth of 5 meters. The revolutionary technology of the green laser goes beyond the limit of operation temperature and allows it to work in room temperatures (0°-35°C). The green laser is eight times more visible than a red laser which makes this device readable in daytime.
