"UFO project" from the past.

The most well-known aviation project from the past is Leonardo da Vinci's flying machine. Sometimes researchers say that the system used flapping wings like a bird. The idea was that the plane used a similar system. That is used in some weight training systems. 

The idea was that the system's user pushes and pulls the stick that moves the wings. The reason that the flying machine didn't work. Was that Leonardo couldn't copy the bird's wing's movement trajectories. But maybe that system could work as a glider. 

But sometimes, some researchers suggested that the system was a glider that wings could put in a cargo position. And in the most incredible theories, the system used ion engines. The stick would ionize the air and the ring would pull those ions through it. But maybe that was a little too complicated even for Leonardo himself. 

Maybe Leonardo planned to use that glider with the great ballista. The giant crossbow would shoot that aviation system into the air. And the user of the system could drop the powder dish into the target. But then we can think that there is a possibility that Leonardo's tank was some kind of aviation machine. 

Some researchers created the UFO, by using Leonardo's tank as the model. The idea of this kind of flying machine was that in the middle of that flying machine is a quadcopter. The quadcopter is responsible for vertical movement. And then the cannons are replaced by radially installed jet engines. That thing allows the heavier-than-air system to hover above the land without noise. 

Aviation systems are always very interesting things. And we can only imagine what people like Leonardo da Vinci would do with the internet and modern computers.  

When we are looking at another of Leonardo's interesting models, his helicopter, the screw-looking wing is interesting. Maybe he created that aerial screw to use as a parachute. We can say that this screw-looking wing is meant for jumping from the cliff. 

So the user of the system will not rise from the ground. The user must only jump from the cliff, and then the screw will slow the jumper's speed. But if the airflow that comes from below pushes the system upwards.

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...
