Paranormal researcher Joshua P. Warren of L.E.M.U.R. returned to the show, to discuss his team's creation of a plasma that resembles the anomalous Brown Mountain Lights.
By reproducing certain elements found at Brown Mountain in their laboratory such as layers of quartz and magnetite (which forms a capacitor), they were able to set off discharges at different angles that created the illusion of a ball of light moving inside a plasma chamber, he explained. Interestingly, he noted that the US is experimenting with plasma for non-lethal weaponry, in which a gun could be set to stun rather than kill. For more, check out photos here.
Warren also shared some of his ghost hunting techniques. He said that still cameras are ideal for capturing phenomena because with their high shutter speeds, they can catch things that can't be seen with the naked eye. He also commented that he is partial to digital cameras because they can capture part of the infrared spectrum.
Dangers of Mold
Appearing during the first half-hour was mold expert and mycologist, Richard Progovitz who shared information about the dangerous aspects of household mold. He noted that asthma and many allergies may actually be caused by certain molds. Progovitz suggested that the product Borax which can penetrate into porous surfaces, when in a paste form, is effective for removing mold from surfaces such as tile grout.
