  • Patent number: 9685774
    Abstract: A lightning protection system for liquid storage tanks having floating roofs wherein lightning energy is not directed into the shell of the storage tank. The lightning protection system includes at least one low-resistance low-impedance bypass conductor cable configured for lightning related frequencies and for routing lightning energy and for bounding charges away from the shell of the storage tank.

  • Patent number: 9166391
    Abstract: An early streamer emission terminal is disclosed. According to some embodiments, the early streamer emission terminal can create an upward propagating streamer earlier than conventional lightning protection systems and/or devices. In particular, the early streamer emission terminal can collect ground charges during an initial phase of thunderstorm development. When a thunderstorm begins to generate downward step leaders, the ambient electric field around a grounded lightning protection system can induce a current into the grounded lightning protection system. The induced current can include a flow of negative charge toward the ground, while a positive charge can be released to form an upward streamer. The construction of the early streamer emission terminal can trigger the flow of positive upward charge microseconds earlier than traditional lightning rods or other similar devices.
