This article calls it antigravity but it’s not. Two high school students built a so-called “ion-wave” aircraft that flies without aid of a motor, fan or engine. Video of the craft flying on the school website has drawn 4000 hits since it was posted a month ago. As written up in The Detroit News, “The craft was made from relatively simple materials — balsa wood, glue, foil, cotton balls and wire — and cost about $200 to construct. The aircraft is triangular shaped and gets its power from a wire that runs along the top of the device. The wire is connected to a power source, which can be anything from a battery to a desktop computer. The secret of the craft lies in a theory on the function of ion waves. The ions bump into oxygen, causing the craft to rise up, according to the students. “The electricity goes from the power supply to the wire, “jumps from the wire to the foil, which creates ion waves, then goes out from the foil into the ground,” Duncan said.” The idea isn’t new – Major Alexander de Seversky patented it and did work on the concept back in the 1960s as the Ionocraft.
