This is a list of spurious inventions, technologies which are generally considered to not possess their claimed capabilities, to be hoaxes, or to not have ever existed in the first place.
Spurious invention | Description |
---|---|
Angel Light | According to its inventor, this device could make walls, hands, and stealth shielding transparent. |
Black box | Popular name for a diagnostic machine made by Albert Abrams. It supposedly could diagnose diseases based on their special vibrations that can be sensed along someone's spine.[1]: 37 |
Chronovisor | A time viewer claimed to have produced photographs and recordings of the ancient past. |
Cloudbuster | A device that could purportedly make rain through manipulating atmospheric orgone, a kind of energy considered to be pseudoscientific.[1]: 55 |
Edison | A device claimed to produce numerous analyses of blood very quickly using very small samples. |
Gavreau's infrasonic weapons | Various whistles and horns, possibly fictional, which could cause serious bodily harm and death by emitting infrasound.[2][3] |
Rife machine | Devices that can, purportedly, by the use of electromagnetic waves, destroy pathogens, including cancer. There is no reliable evidence that the Rife machine works as a cure for cancer.[4] |
Teleforce | A weapon, also known as Nikola Tesla's death ray or peace ray, that would accelerate pellets of material to a high velocity so as to cause significant damage from a long distance.[5] |
Nikola Tesla electric car hoax | Alleged advanced electric car. |
Fleischmann–Pons cold fusion experiment | Attempt to cause nuclear fusion using electrolysis to achieve the high compression ratio and mobility of deuterium.[1]: 56–57 |
Kryakutnoy | Fictional inventor of hot air balloons.[1]: 236 |
Newman energy machine | Supposed free-energy machine invented by Joe W. Newman.[1]: 236 |
Perpetual motion machines | Hypothetical machines that do not need any added energy or force to continue motion. All attempts as of yet are considered spurious, and such a machine is considered impossible by modern thermodynamics.[1]: 248, 262 |
