The U.S. Navy has a 200-foot-long (approximately 61 m) autonomous surface vehicle that can advance its combat capacity. The large sea drones. They can carry large and flexible computer systems that can allow them to operate independently.  Those computers can run complicated and effective algorithms. And those systems can operate as independent kamikaze-drones. Robot missile boats and a platform for flying drones. Those systems can be dangerous to all other vehicles. And they might also have a role as cargo systems. The system is basically similar to the Ukrainian Sea Baby drone, which successfully operated in Simferopol harbour. 

There is also a possibility that those large robot vehicles can act as development platforms for larger and more sophisticated systems. The sea drone, like autonomous surface vehicles (ASV) and Autonomous Underwater Vehicles (AUV), can have an unlimited operational range. If those systems use a Radioisotope Thermoelectric Generator (RTG) that gives electricity to the electric engines. This gives the system virtually unlimited operational range. There is a possibility that things like Orca-class drones can have that kind of propulsion system.

The first hydrogen-powered drones are operating in Ukraine. And they seem promising. Those drones use fuel cells. And the thing. That makes them interesting. It is because. Hydrogen. It is easy to produce. Using electrolysis. 

If we think about. The larger underwater and surface drones use radioisotope batteries. That can be connected. Into a series. As chemical batteries. Those systems can operate theoretically indefinitely. There is possiblity that those drones carry sub-drones that can use hydrogen as fuel. That means that those drones can create. The hydrogen for those flying or underwater swarming drones. By using electrolysis. There is also a possibility. That, quite soon, we will see full-size submarine drones. They might carry supercomputers for running algorithms. The large size, nuclear-powered drone can operate in the same missions as a manned submarine. 

Those drones can operate on hydrogen-powered versions of the Shahed drones or their jet-powered variants. The drone can use hydrogen in the fuel cell. Or it can use hydrogen-powered ramjet engines. In that case, the hypersonic drone or missile must be launched. From the platform, using a rocket, which accelerates the drone to a speed of about Mach 1.

And of course, hydrogen can be used as fuel for the regular piston engines. But, if the thing. Like. An aircraft carrier can have hydrogen-powered aircraft or an air wing. It can create hydrogen from water. By using electrolysis. That gives unlimited operational capacity to those aircraft.

Radiation and information. When wavelength matters.


"Schematic configuration for generation and detection of femtosecond UV-C laser pulses in free space. A message is coded by a UV-C laser source-transmitter and decoded by a sensor-receiver. The sensor is based on an atomically-thin semiconductor grown by molecular beam epitaxy on a 2-inch sapphire wafer (inset). Credit: B.T. Dewes et al." (ScitechDaily, A New UV Laser Sends Messages in Trillionths of a Second)

The new UV (Ultraviolet) laser system allows ultra-fast data transmission through the air. The UV lasers are suitable tools for data transmission because they don’t transfer as much energy to their environment as IR lasers do. The IR radiation is long-wave radiation, which we normally call thermal radiation. The UV radiation has a short wavelength. And its opposite side to visible light in the electromagnetic spectrum. The short wavelength. Allows the radiation to transfer information faster than long wavelengths. 

The zeros and ones in binary data transmission are bottoms and tops. Or hills and valleys in wave movement. The system must also know the breaks of the transmission. So the long wavelength requires that the system must “think” longer. Is the bottom of the wave the break, or is it zero in the line of zeros and ones? The short wavelength allows. The system sends light impulses. Those impulses are like line- or QR codes. 

The system doesn’t require. So much time to start a new binary number line transfer. In a photonic quantum computer. Each wavelength. It is a unique state of the qubit. The system can use different types of lasers. For making those qubits. Those systems can involve fewer states than a system that is in quantum entanglement. The qubit can have multiple states. But finally. Each of the qubit states has values. One and zero. This means that a quantum computer can operate as multiple binary computers. At the same time. The quantum computer can also share complex missions. Between multiple states. That makes those systems more effective. 

The UV light doesn’t heat the target as much as IR radiation, and that makes UV lasers suitable for photonic computers. In electro-optical data transmission. The UV lasers can carry more data than IR lasers, and the UV laser is invisible to IR sensors. This is why. Those UV lasers or UV laser scanners are tools that can break the stealth systems. The UV laser scanner is invisible to infrared detectors. And it's invisible. 

For the human eye. The short-wave radiation. Like UV, X- and maybe someday, gamma rays are promising tools for computing. The X-ray systems can also transmit data through the walls. The reason why short-wave high-energy radiation can tunnel. Through walls better than IR radiation that makes holes is quite an interesting thing. The short-wave radiation pushes quantum fields of atoms. Away from each other. But. It doesn’t let those fields drop back. So the short-wave radiation forms a channel through the wall. 

This channel doesn't form the energy movement that moves back and forth. The thing is that energy pumping doesn’t destroy matter. The end of pumping causes a situation. Where atoms and subatomic particles release their extra energy. That thing causes resonance. And the free energy pushes those particles away from each other. That breaks chemical bonds between atoms and releases. Energy that is stored in those bonds. 





“The general definition of a qubit is the quantum state of a two-level quantum system.”(Wikipedia, Qubit)

At the bottom, there is the binary system. The quantum computer’s qubit forms. Of strings. Those strings are the state of the qubit. Each of those strings has values 0 and 1. So, each of those strings or states of the qubit can act as an independent computer. This allows the quantum computer operate so effectively. It can make. Multiple operands at the same time. The graphene layers that are opposite each other can trap particles in the carbon structures in the middle of those carbon nets. Energy that will transfer to the transmitting side causes. Resonation into particles that are in the middle of those carbon network structures. Another version is the fullerene. There, the surface structure sends string-shaped strings to the central particle. 



“Bloch Sphere representation of a qubit”. (Wikipedia, Qubit). The fullerene can form the Bloch sphere. There must only be the particles in the fullerene’s shell. And then the particle that transmits and receives information in the middle of that structure. The system can send information first from the shell to the particle in the middle of the fullerene. And then that particle or particle group can resend information back to the shell of the Bloch sphere-qubit. 

For making damage, radiation must penetrate matter or a wall. For making damages. Radiation must have the right wavelength. If the wavelength is too long, atoms release their energy slowly. If the wavelength is too short. That means radiation makes a tunnel through the particles. The energy pumping doesn’t itself destroy matter or separate atoms. 



Ball-and-stick model of the C60 fullerene (buckminsterfullerene)(Wikipedia, Fullerene.Fullene can act as a Bloch qubit. 

When energy pumping ends, atoms release their extra energy, and that release must be so strong. It cuts the chemical bonds. That causes the rise of free energy in the system. Things like visible light cause interaction in the surface atoms. That allows those atoms to reflect radiation out from them. It closes the radiation’s route inside the matter. And that’s why the visible light. Doesn’t harm materia. 

The long-wavelength radiation. Like IR radiation also pushes those quantum fields. From its direction. Then the IR radiation allows those quantum fields to interact with each other. Those fields are releasing energy between them when the wave of the IR radiation decreases. When the next wave comes. That wave impacts those energy fields, and the result is similar. With the knocking engine. And that forms standing waves in the wall. 

That transports more energy into those atoms than short-wave radiation. The radio waves also tunnel through walls, but their wavelength is so long. It moves atoms or their quantum fields. Gently. Away from its route. The radio wave’s long wavelength. allows those atoms release their extra energy. Slower than the IR radiation. 

The form of the 2D matter causes the matter to be very strong. The strength of that matter forms because energy travels away from it immediately. The strength and other unique features of the 2D matter form because there is no depth in that matter. 

In the case of visible light, the light adjusts. The atoms like IR radiation. But. The wavelength causes an effect. The surface atoms expand their quantum fields. That denies the wave movement traveling in the matter. So. Most of the energy that visible light sends is reflected back from the surface atoms. For making holes or causing damage. The wave movement must penetrate the matter. The thing that causes damage is the energy that penetrates and spreads through the matter. 

If the energy impacts only the surface of matter, that doesn’t cause damage, because energy has room to spread. This makes the graphene layer so strong. The graphene network allows the energy spread through the layer without resistance. Graphene is 2D matter, and it doesn’t allow. To create deep vertical waves. Most of the energy. Travels from one carbon atom to another. The graphene layer doesn’t allow the creation of so-called long resonance waves that close wave movement inside it. This means that the graphene layer over normal matter would make next-generation armours possible. The graphene layer that stands on carbon pillars. 

Denies the formation of those deep-standing wave pillars. And that allows energy transfer off the graphene. If low-energy particles flow between the main layer. And graphene. That makes it possible to create a layer that can conduct energy away from it very fast. If the grapahe layer hovers above the main layer, that thing denies energy transfer to the main layer.
