Graphene as an insulator. And nano-size hovercraft.

The system can use the same effect to transport miniature robots on water.

In the center, electron microscopy shows a top view of the material indenene as a triangular lattice. Below it is a side view of the silicon carbide substrate. It can be seen that both the indenene and the graphene consist of a single atomic layer.

New electric systems require an extremely good insulator. Nanotechnology means that old-fashioned insulators are useless. A graphene membrane can protect components against water. The electric flow in the graphene makes it a good insulator that denies the inner side of the topological insulator getting outside effects. That kind of thing makes graphene one of the most interesting materials. The same thing that can make graphene repel water can be used in new nanotechnical solutions.

One of them is the nano-size robot that can hover above water. The system can make an electric load on graphene, and the system can hover above the layer using some nano-acoustic systems. That thing can make the small graphene hovercraft rise above the water layer. 


In a graphene structure, the fullerene balls are like small wheels that transport the miniature machine forward. There is the possibility that nano-diamonds send acoustic waves that make this system hover and move at least in liquids. In nanotechnology, small sizes of machines make them more effective and behave in other ways than their "big versions". 

In some models, graphene can trap water molecules. When the system turns the minus or plus poles in a certain way. It can be used to aim ion beams into the right position. The system can put behind the object, and then the ion cannon shoots ions. In that case, the opposite electric pole pulls ions into it. And that increases the ion system's accuracy. 

Graphene can also be used to trap water in it. The ability to change the direction of the water molecule makes it possible to create ultimate stealth materials. If the system can turn the molecule's positive or negative side outside, that thing makes this thing possible to create a layer that can pull electricity or radiowaves in it.

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...
