![]() "My imagination leads me to speculate on applications like 'bulb-less' light sources, coating and deposition or energy production," he said. A short-exposure photograph taken during the extinction phase gives the picture of a freely floating plasmoid, a few meters in size, irregular in shape with a rather sharp boundary. Jerby thinks that his laboratory lightning balls could one day find practical uses in industry. Yesterday the inhabitants of Lewisham were provided with a specimen of that curious phenomenon known as globular lightning.' It is what is commonly called the fire ball.' and as It persists for several seconds It Is obviously of a-totally different character from any other form of lightning. Abstract A lightning stroke on a power line tower has been observed at a distance of 180 m. ![]() The particles react with oxygen in the air and release light as they burn. ![]() whilst the greater number of discharges described as globular lightning are. The vaporized nanoparticles could then link together into chains and form a fluffy ball of silicon that floats on the wind. He then referred to a number of historic ball lightning reports included in. "Our experiment confirms to some extent the theory that ball lightning originates from hot spots in the ground created by normal lightning," Jerby told LiveScience.Īccording to one popular theory, ball lightning forms when lightning strikes the ground and vaporizes mineral grains in the soil. The composition of the laboratory lightning ball still needs to be verified, but it appeared to resemble those found in nature. The work was detailed earlier this month in the journal Physical Review Letters. The glowing object measured just slightly over an inch across and lasted only about 10 milliseconds. "The fireball like a hot jellyfish, quivering and buoyant in the air," Jerby said. The energy from the drill created a molten hot spot in the solid object when the drill was pulled away, it dragged some of the superheated material along with it, creating a fire column that then collapsed into a bright fireball that floated and bounced across the ceiling of the metal enclosure. Despite this, there are more than 10,000 written accounts. The researchers aimed the beam through a pointed rod and into a solid object made from glass, silicon and other materials. It is estimated that only one in a million lightning strikes produces the ball lightning phenomenon. Eli Jerby and Vladimir Dikhtyar from the University of Tel Aviv in Israel created a laboratory version of ball lightning using a "microwave drill." The device consists of a 600-watt magnetron taken from a domestic microwave oven and uses a powerful microwave beam to bore through solid objects. Lightning is the separated polar state reuniting and voiding back to wholeness or neutrality, its origin before separation or polarization.
