"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.

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

There might be an answer to why there is a gravitational hole in Earth's gravitational field.

The gravitational field at the point of the Indian Ocean is weaker than in other places on Earth. The existence of that gravitational hole is proved. But the reason why that gravitational hole is formed is unknown. The reason why the gravitational field on the Indian Ocean is weaker might be a simple thing.  There is a possible lighter rock in the mantle, or there is less material at that point. In some wildest theories, there are bubbles in magma that turn below the bottom of the Indian Ocean are less massive than in other places on Earth. The lighter material at that point should make the hole in gravitation.  "Geoid undulation in false color.
