The "space helicopters" or MHD-driven aerial vehicles can revolutionize aviation.

Engineers can install the MHD (Magnetohydrodynamic Drive) engine system in lighter-than-air vehicles. That allows them to operate also in the atmosphere. Normally, MHD cannot rise heavier-than air crafts from the ground. But that system could work with high-altitude airships. If those craft's body is made by using modern carbon fiber-based materials they could fly to space. Researchers can use these kinds of systems in the HAVOC (High Altitude Venus Operational Concept) mission to Venus's atmosphere. Or at Earth's atmosphere.

The ion engines are one of the most promising systems for interplanetary missions. But ion engines, or electric jet engines can also use in aircraft. Those engines are ionizing air in front of them, and then the magnetic accelerators will accelerate those ions to the back of the system. This kind of ion system could make the aircraft very highly maneuverable. Advanced ion systems are powerful tools. They can form ion whirls that crush all meteorites or ammunition that are closing spacecraft or aircraft.

Originally engineers planned to install this ion propulsion system in plate-looking submarines. The ion system just ionizes water. And then, drives it in the wanted direction. This type of MHD (MagnetoHydrodynamicDrive) aims at the direction of the ion flow by inclining the plates. In some models, the MHD drive would install in airships. That thing makes it also suitable in atmospheric flight even if it cannot lift heavier than air crafts upward.

There are also introduced models where the system uses the electric arc or rocket engine that creates pressure between plates. The system would incline the plates that allow it to control the direction of the jet. Those systems can use two plates that are acting like Kamov-type rotors. The overpressure system could quite easily install in the same structure with MHD/MDD (Magnetodynamicdrive).

The plate-looking aerial vehicle which uses ion engines can be the source of UFO sightingsThe electric system will ionize the air in the front or middle of that structure, and then the system will incline to the plates. The system would use radially installed magnetic tracks that aim the ion flow into the wanted direction. That kind of system can make the craft able to make a very strong maneuver.

Some futurologists made a theoretical model of the interstellar or interplanetary spacecraft that uses black holes or electromagnetic, virtual black holes for operating in space. The system makes the plasma disk around the craft using high-power magnets. Then they would shoot the plasma pikes in the disk and that causes asymmetry which pushes the craft forward. The problem with those systems is the power source.

That ion whirl also can form the Tipler-cylinder around the nuclear-powered spacecraft. This type of system could also use small-size black holes for making the plasma disk. But basically, those kinds of systems require only high-power magnetic fields. Another thing that this ion whirl can make is aim the radar signals away from the structure of the craft. The ion whirl can also form the ion-based power field around the craft, and those ions will destroy all incoming material targets.

Use virtual "perpetual motion machines" and seawater as energy sources.

Use virtual "perpetual motion machines" and seawater as energy sources. The Archimedean screw can offer almost endless energy sources. "Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving. It is widely credited as the first attempt to describe such a device." (Wikipedia/Perpetual motion) The term "virtual perpetual motion machine" means a machine. That pulls water to the upper tank using a capillary tube. Then that water will fall through the generator or turbine wheel. The machine uses differences in pressure levels. But it looks like a "perpetual motion machine", that is impossible because of laws of thermodynamics. The machine uses differences in pressure levels. But it looks like a " real perpetual motion machine", which is impossible because of the laws of thermodynamics. The real perpetual motion machines don't use outside energy. And that's why they are not possible....

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger. The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth. It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons. It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho...

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field. An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate. AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru...
