1. "Greek Fire"

Who likes to play history-smelling games may know. This is the weapon used by the Byzantine empire, especially in the battle at sea. Rumour said the fire still alive on the water. The manufacturing process and its technical materials were completely concealed by the military of that era. The ingredients of the composition are said to contain naphthalene, calcium oxide, sulfur, etc. This weapon is said to be the inspiration and forerunner of the modern flame-thrower.

1. Orgone
   This one I've read tritnya in Kaskus. Orgone by Reich is a hypothetical form of energy expressed as a universal bioenergetic force that produces life energy that is useful for therapy. The orgone energy-generating device itself has been made with a combination of wood, iron and organic materials. Until 1950, the device was bought and sold. But the FDA (BPOMnya Amerika), protested due to research on orgone that is not diapprove by many scientists. The court granted, and ordered orgone-producing tools to be destroyed, and Reich's books on this topic were also banned.

2. "Perpetual Motion"
   Simply put, this tool is said to produce more work than the energy consumed (certainly not possible violate the law of energy conservation). Schauberger actually claimed not to make this tool, he claimed to use the natural power of the earth, but the gossip that he managed to make it heavily circulated. After World War II, Schauberger was arrested and interrogated about his research. The entire archive of work and prototype confiscated.

1. Terapi ozon
   The devices associated with this mechanism are actually widely circulated. Some doctors believe ozone has the ability to heal. But ozone is also toxic and in certain levels dangerous. Although empirically proven that ozone has reduced the effect of some diseases, the use of ozone for therapy is strictly prohibited in various countries. America even prohibits marketing, use, or even research on the clinical benefits of ozone therapy. Doctors who use it were threatened to lose their medical license.

1. Perangkat anti gravitasi
   In 1956, Interavia, a flight publication reported that Brown succeeded in making a substantial progress in electro-gravity propulsion research. Many aerospace projects in America are also conducting similar research, and are highly secretive. Brown himself argues that his work could explain the working mechanism of 'flying saucers'. Brown's research is very popular and is followed by amateurs around the world by making replicas, in the form of 'lifter' with high voltage power source.

1. Perangkat fusi dingin
   Simply, cold fusion is a process of nuclear fusion in a temperature equivalent to normal room temperature. Mallove is the author of the book Fire from Ice, which contains the report and the follow-up research of Fleischmann-Ponn about cold fusion. Reportedly, his research can generate enormous energy from the process. However, it seems his research was ridiculed and rejected by many mainstream physicists. Mallove was murdered in 2004 in Connecticut by a stranger. Reportedly his death was related to the results of his research.

2. Water fuel cell
   Meyer successfully patented 9 patents related to hydrocarbons. But then he was sued by his investors for alleged fraud, and had to compensate for $ 25,000. At the time of his death, an autopsy showed that he died of swollen blood vessels. His supporters claim that he was killed by a giant oil corporation, a mercenary from the Middle East and Belgium, and the American government, to cover up his invention

3. Earthquake engine
   While experimenting with one of his oscillators, Tesla reportedly made resonances on nearby buildings, and complained to the police. As a result of the large shock produced, he was forced to destroy the tool and thwart his experiments. This topic was once on Discovery Channel MythBusters, where a phenomenon called mechanical resonance is tested on a bridge that should hold out of that size. When the oscillator is applied, it is evident that the shock occurs on the bridge, but without the cracking effect on the ground. This may explain the phenomenon that Tesla did, given the ancient times no building was built that could escape such resonance.

4. "Flexible Glass"
   ni is a legend of a stunning discovery early in the year AD. It is said that a craftsman who invented the technique made the cup emperor made of flexible glass, and when the emperor dropped it on the floor, the material was just dented, and not broken. The inventor then fixes it easily with a hammer. When the inventor promised that only he knew the technique of creating the material, he was beheaded. The emperor feared such material dropped the value of gold and silver.

5. Chronovisor
   In 1960, Ernetti's father claimed to have created a cross-time vision device, called Chronovisor, and was rumored to be able to see events in the past. According to his explanation, the energy and sound produced by an object are stored in the environment. The proper setting of the Chronovisor can reconstruct that energy into the image and sound of an event in the past. Through the screen, Ernetti's father claimed to see an appearance of poetry in the mass of ancient Rome before Quintus Ennius. He also claims to see Christ dying on the cross. Before his death in 1994, Ernetti's father said that he and all those involved in the Chronovisor's study attended a meeting at the Vatican, where the Chronovisor's only machine was destroyed.
   but until now all that remains a question mark
