Here's another weird creation during the time of the Nazis. A development unit of the SS occult “Order of the Black Sun” was tasked with researching alternative energies to make the Third Reich independent of scarce fuel oil for war production. They supposedly developed in 1939 a revolutionary electro-magnetic-gravitic engine to create powerful rotating electromagnetic fields that affected gravity and reduced mass. According to legend, the Haunebu I first flew in 1939. Further plans for a 120 meter diameter Haunebu IV were in the works but no such craft is known to have been constructed before the end of the war.Hanebu IV Papercraft
