1. Tesla's 'Death Ray'
Genius scientist Nikola Tesla once conceived the idea of creating a 'gun' that shoots a type of ray called the 'death ray' in the 1930s. This special weapon operates by firing a beam of particles containing immense energy through the air, capable of destroying up to 10,000 fighter planes within a range of over 300 km. Tesla believed that if his idea were disclosed, it would mark the end of all future wars, as every nation would strive to acquire such a 'gun' to boast its supremacy. Due to its extreme danger and the fear of falling into the wrong hands, the design of the 'gun' may have transformed humanity, never being publicly revealed by Tesla, and it went to the grave with him when he passed away in 1943. Later, some close associates of Tesla rumored information about the 'death ray.' There were even reports that in 1937, the Soviet Union attempted various experiments but failed. The Soviet military at that time could not implement this weapon with the incomplete details of the dangerous invention they possessed.


2. Sloot's Digital Encryption System
With extraordinary creative mind, information technology genius Romke Jan Bernhard Sloot invented the secret to compress the size of large GB movies to as little as 8 KB (1 GB = 1048576 KB). In 1999, he successfully protected his research work from the tech giants of that time and convinced them to buy it. Jan Sloot used a 64 KB chip to store 16 movies and presented them in front of them. Everyone present at this event was amazed and thought he would surely become a billionaire by selling the product of his idea. However, just two days before transferring this excellent algorithm to his partners, he mysteriously passed away. It was rumored that Jan Sloot had a heart attack, but it could also be an assassination to steal his great invention. The details of the chip and the secrets of the algorithm forever disappeared, leading to these suspicions.
3. Tower Broadcasting Energy to Illuminate the World
Nikola Tesla once startled the world by predicting a day when the Earth would be plunged into utter darkness with no sunlight. Thus, from his genius mind, he planned to create a type of
dilute sensitive gas, with the ability to glow and provide light for the entire world. His plan was to use ultraviolet rays containing an immense energy source to shoot at gas particles, making them emit light. The construction of the Wardenclyffe Tower in Shoreham (USA) was underway to serve this plan, along with a power-producing telecommunications facility here. If this plan succeeded, the entire Earth might not need sunlight anymore but could use a free wireless energy source. The initial plan seemed fantastic and smooth, but when presenting the idea to JP
Morgan (one of the oldest and largest financial institutions in the world, headquartered in New York) for sponsorship, he was rejected due to its low feasibility. As a result, shortly afterward, Tesla's global-scale energy supply project went bankrupt due to lack of funding.


4. Starlite - Super Insulation Compound
A synthetic material existing in both liquid and solid forms named Starlite was created by a chemistry enthusiast and hairdresser in the UK - Maurice Ward, in the 1980s. It is an incredibly lightweight compound with unbelievable insulation capabilities, surpassing any compound ever created. Through experiments, a Starlite compound sample could “survive” and withstand the destructive power of a nuclear bomb, equivalent to 15,000 tons of TNT, and endure temperatures exceeding 10,000 degrees Celsius. An impressively durable material. To demonstrate its true potential, Maurice coated it on an eggshell and used a 3,000-degree Celsius diamond spark to ignite it. What happened was beyond imagination; the egg, supposed to explode under that temperature, remained completely intact, even the egg white and yolk were unharmed, thanks to the protective layer of Starlite.Initially, many people and organizations doubted the idea that “a hairdresser's mind could create a compound that could change the world if used in warfare” like this and thought it might be a hoax. But after undergoing various serious experiments, experts in the field of materials were genuinely convinced. They could not have expected that Maurice refused to sell the ownership rights of the formula, valued at millions, even billions of USD, and sadly, the invention was “lost” along with the death of its creator in 2011.


5. Chronovisor - Time Machine
In 1960, Pellegrino Ernetti, an Italian priest, claimed that he, along with two renowned physicists Enrico Fermi and Werner von Braun, created the 'Chronovisor' – a time machine, functioning like a recording device to capture events from the past during space-time travels. The priest revealed further: by using Chronovisor, he recorded horrifying scenes including the crucifixion of Jesus and the death of Napoleon. The time machine was described as a box with peculiar tools, capable of unraveling the deepest mysteries of the past. However, instead of altering humanity with this time machine, to prevent potential consequences, the group of inventors destroyed the machine themselves, before Pellegrino Ernetti passed away in 1994.


6. Roman Concrete
The concrete walls in ancient Rome, up to now, are nearly 2,000 years old. With the most innovative technology in construction at that time, this is one of the most concrete evidence for the superior features of Roman concrete over other materials. Compared to the skyscrapers, made of contemporary concrete, which deteriorate or even collapse in only about 50 to 70 years, the ancient Roman concrete walls have stood the test of time. In recent years, many researchers have invested a considerable amount of effort to explore the secrets of creating such durable walls. The volcanic ash has provided surprising hardness and stability to these ancient structures. Archaeologists from the University of California-Berkeley revealed that the enduring compounds (C-A-S-H) in the Roman concrete blocks still existing today typically include calcium, aluminum, Silicate (a compound containing silicon anions), and Hydrate (a water-containing substance) binding the materials together sustainably. Unfortunately, no reliable records or detailed scientific evidence have been found about the construction secrets of this type of material. If they were discovered, they would undoubtedly revolutionize the current construction technology worldwide.


7. Fuel-Efficient Carburetor Box
Tom Ogle – an ordinary mechanic was the owner of a special invention. Tom's invention is a black box similar to a regular car carburetor. If you remove the normal carburetors and replace them with the special box created by Tom, our cars would run several hundred more miles with the same amount of fuel. This fuel-efficient box was tested by the mechanical experts of that time and was recognized as a groundbreaking innovation. Oil companies spent billions of dollars to bribe and hope he would stop making these machines because Tom's invention could bankrupt them by reducing fuel sales. Unfortunately, not long after, Tom Ogle was assassinated by a gunman in 1981. The method of creating the super carburetor should have forever changed the global automotive manufacturing industry buried deep in the grave with him. Public opinion immediately speculated that the death of the genius mechanic's brain was related to the oil companies.


8. Water-Powered Car
Stanley Meyer (1940 - 1998), a talented mechanical engineer, turned the impossible into reality. He transformed water into Hydro energy to power his car, traveling from New York to Los Angeles using just over 80 liters of water. His engine system was equipped with various small mechanical parts working in harmony, capable of separating water molecules into hydrogen and oxygen molecules, thereby providing energy to drive the car. The vision of vehicles running on water, without the need for expensive gasoline, seemed imminent, opening up new hope for an era without energy crises. However, things took a terrible turn compared to its prospects. Stanley Meyer passed away mysteriously in 1998 at the age of 57, and his innovation and research came to an abrupt end. Family members recounted that many large companies in the automotive and oil industries had contacted him, expressing interest in buying his innovative idea for billions of dollars, but he refused. This could be one of the reasons why geniuses like him are often plagued by adversaries. If Stanley Meyer had not left us so tragically and his groundbreaking research had been widely adopted, the world today would undoubtedly be different. People wouldn't have to breathe toxic car fumes when outdoors, and we wouldn't be so reliant on fuels like gasoline.

9. Flexible Glass
Countless oral stories and numerous alternative accounts circulate about the world's first appearance of flexible glass. It remains uncertain whether it ever truly existed. In an ancient work by the writer Petronius, there is a passage recounting that a skilled glassblower presented to Emperor Tiberius (the second emperor of the Roman Empire, reigning from 14 – 37 AD) a newly crafted glass vessel. While observing, the emperor accidentally dropped it to the floor. Astonishingly, the distance from the emperor's lofty throne to the ground exceeded a meter. However, the glass container remained unbroken, with just a slight dent in one corner. With a few simple maneuvers by the craftsman, his miraculous invention returned to its original state. Emperor Tiberius was delighted that the precious gift remained intact without a single crack. Yet, on the other hand, he harbored a fear that this flexible glass production technology might overshadow the value of gold and silver, potentially disrupting the economy and causing chaos in the world. To keep the secret of this technology, Tiberius ordered the execution of the craftsman, and the secret of flexible glass was lost forever.


10. Anti-Gravity UFO
Renowned astrologer Ernst Zundel gained fame not for groundbreaking research but for a wild UFO hypothesis. However, the Nazi regime embraced this absurd idea to nurture hopes of creating a peculiar flying object—a means of transportation with the ability to defy gravitational forces. Their primary aim was to establish contact with extraterrestrials for potential military assistance in case of invasion. Following the Nazis' defeat in World War II, they fled to the South Pole, persisting in their ludicrous project with aspirations of global dominance, continuing to wage revenge wars and transform humanity. Fortunately, a joint investigation involving the United States was conducted to examine the scientific credibility of this particular UFO's feasibility. The experts concluded it was merely a far-fetched, delusional project, and, naturally, the venture was promptly dismantled.


11. Mysterious Greek Fire
The inscription in the image below roughly translates to “The Greek fleet is burning the enemy fleet.” The confidence of Greek warriors at that time stemmed from possessing a superior weapon, the mysterious chemical flamethrower.
This ferocious fire could incinerate even a colossal warship on the water's surface, and as described, could only be extinguished by vinegar, sand, and urine. However, in the vast sea, especially amid intense combat, where could one find those materials? Until today, no one knows precisely what chemicals were used to create that weapon of destruction. Perhaps the Greek navy foresaw the unpredictable consequences if this invention fell into the hands of some ruthless warmonger. Hence, they discreetly kept the secret to themselves, deciding to take the formula to the grave, adamant about not leaving it for any successor.


12. Archimedes' Sunbeam Weapon
Archimedes, the renowned Greek scholar, once invented a weapon known as the 'heat ray.' This invention had the potential to harm a large number of people, described to include massive bronze shields used to reflect sunlight, creating deadly flames capable of incinerating an enemy fleet. Although the Mythbusters research program failed to reproduce this dangerous weapon and declared it a myth, the Massachusetts Institute of Technology (MIT) somewhat successfully executed this 2,200-year-old invention in 2005, burning a small boat in San Francisco harbor. Since then, concerns have arisen that the ingenious invention of Archimedes, the Greek scholar, could devastate the world if used in a war. However, it remains strangely peculiar that no one has been able to recreate this horrifying scene again.


13. Panacea Elixir
Anti-gravity UFO Panacea Elixir is an idea attributed to the head of a nation rather than an unknown do-gooder. It is believed that King Mithridates VI of the Pontus Empire (reigned from 120 - 63 BCE) proposed the concept of concocting a universal remedy with the ability to save humanity, cure all diseases, and revolutionize the entire face of the future world of medicine. Although the exact formula of this elixir has been lost to time, there are still many medicines labeled as “panacea elixirs” including opium, snake venom, and various synthetic dangerous drugs along with their antidotes,... These “innovations” have not improved the medical field, only knowing that introducing this universal antidote into the body is sure to heal a little and harm a lot. However, whether we like it or not, it must be admitted that if King Mithridates VI's idea had succeeded, it would have transformed all of humanity if not lost to history.
