Around 300 A.D. a father, enraged when his daughter converted to Christianity, beheaded her. After the decapitation he was killed by lightning. His daughter was anointed Saint Barbara Dioscorus, the patron saint of lightning victims. British military officer, Major R. Summerford while on the battlefield in Flanders in February 1918, was knocked off his horse by a stroke of lightning, paralyzing him from the waist down. In 1924, while fishing with two friends, lightning hit him again, paralyzing his entire right side. In 1934 a third lightning strike hit him, leaving him permanently paralyzed.  Two years later he died and was buried. Just after his internment, another bolt of lightning struck the cemetery destroying the tombstone of Major Summerford. From bolts to liquid...Water is the most widely used material and second on the list is concrete. Concrete cannot be fully recycled however a resurrected solution includes the use of lightning.  Researchers from the Fraunhofer Institute for Building Physics in Holzkirchen, Germany revived a method, developed by Russian scientists in the 1940s, called electrodynamic fragmentation.  The problem with recycling concrete is breaking down cement, water, and aggregate or the mixture of stone particles - consisting of gravel and limestone grit.  The team placed concrete in water and blasted it with a 150-nanosecond bolt of lightning.  The bolt ran through solid material, creating a small explosion that tore apart and broke down the concrete components. The fragmentation plant processes one ton of concrete waste per hour with larger volumes expected in the future.
