List:
- Virtual holodeck: based on Star Trek but it is actually an open-world virtual simulation through immersive reality which involves projecting energy that creates solid objects in achieving the creation of an actual 3D simulation of a real or imaginary or fictitious setting
- Cloaking or conceal device: using new technologies and successful research experiments in using the new technology to hide or make a person or any object invisible to others which rendered undetected even when it comes to encountering an opponent during such wars or dangerous objects.
- Chronovision: A machining device invented by an Italian priest, named Father Pellegrini Maria Ernetti in 1950 which could be used to let users see the past or important events within the chronology or a span of history but unfortunately, neither could be the truth or not as it was found hidden within the vault of the Vatican.
- Ogle's carburetor: An efficiency tracking device that was made in 1977 came close to reality but the inventor has mysteriously died of unknown circumstances
- Ekranoplan: Highly efficient and fast in terms of speed but it could be flown on both the ground and around the water and it was the fact it is considered a ground-effect vehicle propelled by the air in fact, these ekranoplanes are operated on the water which led to accidents and engine failures less hazardous but in fact the lack of attitude control which means collision with other objects are likely risky while operating on that failed technology. Take-off in high winds or strong winds must be into the wind where the craft could take time in traversing the successive lines of waves that led to heavy pounding which puts the craft under stress and has sometimes made the ride uncomfortable.
- Nuclear-powered automobiles and aircraft: Both cars and aircraft have their power being harnessed and propelled by the usage of existing nuclear energy which can produce a jet engine that could heat the compressed air with the heat from fission, instead of heating from fuel while those cars that could have a small nuclear reactor which the nuclear-powered cars could use a spark-initiated internal combustion engine with fission instead of burning cars using the combustion engine where it is propelled by a fossil-based fuel if it is possible to be used as an alternative to gas-based cars.
