New alloys and graphene. They can revolutionize thermal control.

The Sierra Space Corporation’s Dream Chaser. And Boeing’s X-37B are the pathfinders for next-generation space technology. They are also the response to Chinese Shenlong and larger Haolong space planes. 

The new materials can transform aviation forever. New graphene and metal alloys make it possible. For. Create structures that withstand mechanical stress and heat at new levels. The 3D-printed graphene filament is delivered over the surface. 

It can give 50% higher impact strength. 3D printer technology. It makes it easier to cover large areas by using graphene filament. 

For that structure. Those filaments can boost the development of new armours. And they can be used in all vehicles, from drones to satellites. The graphene filament can turn things like bullets highly penetrating. Those new materials can make hybrid structures. The graphene filament. That is on the alloy. It can be used in high-temperature technology. That technology opens a new path for nuclear systems and high-temperature structures. 

There are space planes like X-37B. But the problem with those systems is this. They are quite small. They use regular rockets for lift-off. And that means they are noisy. But the larger-sized space planes that the high-flying stratospheric drone takes to high altitude. They can solve those problems.  Stratospheric drone. It can use a regular turbojet. With. An internal oxygenizer. Those drones can carry the space plane to the edge of space. There it can be launched. But the larger systems. They have more capacity. The X-37B is a robot spacecraft. Because. Of its small size. The future Dream Chaser has two variants. Unmanned cargo. And a manned version. That spaceplane will be launched in late 2026. 

If. The Sierra Space Corporation's plans stand. And there are no technical problems. 

Those alloys are necessary. In R&D work. For creating new types of hypersonic vehicles that must face very high thermal loads. Those materials are also important for creating new space planes. That can operate from regular runways. Or even by using VTOL technology. The VTOL spaceplane. It could use the jet engines under its belly to rise from the ground. Or the system can use large quadcopters or high-flying drones for that work. Those drones raise the aircraft to the high atmosphere. And then it can release it. The jet engines will accelerate it to speed. That is about Mach 1. 

The Boeing X-37B. 

Shenlong below Harbin H-6. About 5 years ago (Internet)

“An illustration of China's robotic Shenlong space plane above Earth. (Image credit: Erik Simonsen/Getty Images)” (Space.com)

“© The Daily Galaxy --Great Discoveries Channel - 32 Feet Long, 26 Feet Wingspan, and Under 7 Tonnes: Meet Haolong, the Future Chinese Cargo Spacecraft” (The Daily Galaxy)

“A US-built 3D printing system designed to manufacture aerospace-grade parts wherever they are needed is getting a materials upgrade that could make printed components lighter and stronger.” (Interesting Engineering)

And then it can launch ramjets. Or the system. It can transfer to use rocket engines when turbojets raise it high enough. The system can also use the existing technology. Their regular aircraft raises that space plane to the high atmosphere. The system can carry it under the wing. Or on the back. Or the jet fighter. It can pull that rocket plane behind it. Then that jet fighter makes the ballistic jump. But the problem with the space planes is not their price. The problem is in their heat stress. The space shuttle used ceramic structures. That binds the thermal energy.

But the problem was that some of those ceramic bricks were single-use. This means that. The crew must remove and glue the new bricks to replace the used ones. The function of those bricks is based on that. When they evaporate, they transfer energy out from the space shuttle’s body. The accident of the Columbia Shuttle. It was caused by damage in one of those bricks. The heat drilled itself. Into. The body of the shuttle. And then a hole formed. And air pressure made the rest. Causing seven deaths. This is. One of the examples of why. Those space planes are so hard to make. When we think about causes like the X-15 and SR-71. Engineers used titanium in their bodies. But those planes required full-scale checks after the flight. 

One model. That can make rocket aircraft and spaceflight everyday work. It could be the active cooling system. The cooling system can involve a thermos bottle of low-temperature gas. The gas, or so-called Bose-Einstein condensate, will be released to the spaceplane’s shell. To cool the structures. The core of the spaceplane. It can be equipped with tubes. There, that very cold material can move. When the system sees that the temperature rises too high. 

Condensate. It will be released. When the craft is on the ground, engineers can change that thermos bottle. Or. They can fill that bottle with a new ultra-cold condensate dose. The ultra-cold condensate. It can fit in a quite small space. And it can be used for cooling the shell. And if the spaceplane does not travel back and forth between orbit and atmosphere. There is no need to store a lot of condensate. The ultra-cold condensate that cools the structure. It can also decrease the hypersonic missile IR signature. 

Those kinds of active cooling systems. They can make aircraft and missiles capable of traveling faster than ever before.

Humanoid robots are perfect companions and bodyguards.

Scientists restored the sense of touch. By using brain simulation. Stimulation was created. By stimulating the right brain areas with electric impulses.  This operation. It was performed. To a patient who had a spinal cord injury. This technology. It could be an interesting tool. The sense of touch. By using electric brain stimulation. It creates new possibilities for injured people. That technology. It could be connected to bionic limbs. 

This technology can make it possible to control robots by using brain waves. Those robots can act as external bodies for people who need them. That kind of ability can also make it possible for people who need extreme accuracy in their work. The surgeon who uses that system gets better touch with the instrument. If. That person uses a remote-controlled robot as a surgeon. That tool can save lives in remote areas. In the same way, people. 

People can use humanoid robots as their assistants. Those robots can be operated over the net. And that allows the user to stand on the other side of the planet. And then make things like repairs using humanoid robots. Virtual reality and brain-computer interface. They can help. To control robots. They are another body for the person who has access to those systems. The humanoid robots. They can do many more things. Than humans. If there are different people. Who control those robots. The mechanic, gardener, and doctor. They can have access to the same robot body. Those systems can be suitable for remote areas. Or in dangerous situations. 

But the AI is a tool that can make those systems do much more. The AI. It can create synthetic EEG curves. And that system. It can create a sense of touch for virtual reality. This can give a full-scale experience. While. A person is in virtual reality. The person who has these kinds of systems. They can get a 100% real-feeling experience from virtual reality. This ability is the tool. That can revolutionize things like training. In the same way. As the sense of touch, all other senses. 

They can be transmitted to the BCI user. And that means that the robot body. It can operate as the external body. That can assist people. This kind of system. It can be the next-generation butler.  But we know that China and even North Korea are interested. About the robots. That mimic people. Those humanoid robots. They can be perfect companions. But they are also perfect surveillance tools. 

Moya Robot. 

The new Chinese AI-controlled biomimetic robots. They look shockingly human. And we know the Chinese government is invested in those biomimetic robots. And. Robot insects. So we must understand those systems. They have always had a role in military, security, and intelligence operations. Programming determines the skills that robots have. And things like shadow protocols. They are tools. That can turn a nice nurse-robot into a security operator. When. Those robots see something. That risks the patient or person that they must protect. Those robots can activate the protection mode. 

The human-shaped robot. It can get any person’s face. So, there is a possibility. That. The person will be replaced. By. This type of humanoid robot. And we know that humanoid robots. They can even make kung-fu matches. Those flexible systems. They can be perfect companions. And. At the same time. As perfect bodyguards. But they can also be perfect tools for controlling people. The fact is that. Robots that the AI controls. 

They follow the rules of AI. So, those robots. They are not thinking. They have no conscience. They follow their algorithms and operators' orders. So, that means. If. Those people. They try to escape. Those robot butlers. They can stop that attempt. This means that those systems. They can be perfect agents. They can deny that person’s escape. And they can be perfect undercover operators. Those robots can also listen to what people talk about. And report those observations to the secret police HQ. 

The humanoid robot that looks like a human. It can turn dangerous. In the case that the producing country turns into conflict with the country where those robots are used. In that case, those AI-controlled biomimetic robots can be reprogrammed. Those robots. They can also operate as guards.

Autonomous drone technology is advancing.

Drones are game changers in the Ukrainian conflict. Their R&D cycle is so short. That things that had top priority a couple of months ago. They can become old-fashioned in a couple of months.  We know that without drones. Ukrainian defence would fall. The new autonomous, AI drones are now in use. Autonomous AI-controlled drones are the new tools for military and other systems that must operate in places. There.  EM radiation can disturb control signals. The optical wire-controlled drones are effective. But their optical wire causes limitations. In the worst cases, those wires can be spotted. And the laser systems or drones. The mechanical cutters installed can cut that wire. The wire-controlled drone. It also has limits in its operational range. 

The independently operating drones that can use AI to search and destroy targets are the new tools. The independently operating drones can be like full-size aircraft. Or some other vehicles. Drones. They can transmit reconnaissance data. During their flight to the target. They can also be used to transmit data. About the radars and target detection routines of the anti-aircraft systems. 

The first independent fighter drones made their debut. In combat exercises. Those “Ghost Bat” drones. They are the first public versions of the AI-driven systems. The AI-driven long-range stealth drones. They can be the response to the extremely long-range operations. Like Iranian nuclear facility destruction. The B-2 bombers. They made that mission. In a 36-hour operation. There, they dropped GBU-57MOP bunker-buster bombs on those targets. Those MOP bombs. They can also destroy nuclear missiles in their silos. 

The AI-controlled jet fighters. They can make those systems. More surprising than ever before. The AI-controlled systems. They can make kamikaze attacks. And they have the ability to make air-combat manoeuvres during those operations. Data that those drones share.Can be used to train AI. Training AI pilots can be done by using simulators. The simulator operators create tactics and manoeuvres that are suitable for any situation. The AI that operates aircraft is quite easy to train. 

A normal flight combat simulator. It can be used as an interface that trains those drones. AI can give a new dimension. To the loyal wingmen drones. Those drones. They could act as jet fighters. But they could also act as missiles. Same way as aircraft. Naval vessels can get a seaborne version of those loyal wingmen. This means that submarines and surface ships can be escorted by kamikaze boats or small underwater kamikaze drones. The kamikaze drone boats. 

Electric-powered versions of drones. They could operate under and above the surface. The nuclear batteries. They can give all surface-, underwater. And airborne vehicles unlimited operational time. 

They can also escort any surface vessel. Things like RTG (Radioisotope Thermoelectric Generators) give underwater and other drones virtually unlimited operational range. Transforming some Shahed-type drones into RTG-powered drones is not very difficult. The drone requires a nuclear isotope battery. Those drones might not make attacks. Or they can carry missiles and drones under them. Even if those drones are slow. They might not be easy targets. Stealth technology makes them invisible to radar. So. Small-sized RTG-powered drones. They can operate unseen in hostile airspace. 

And an electric engine. It could carry an attack drone under it. The problem. It is that. If those nuclear batteries fall into the wrong hands. That radioactive material can turn dangerous. But the RTG is a suitable powerhouse. For the nuclear-warhead torpedoes. And the nuclear-powered airborne drone. It can turn. To use a jet engine when it must make an attack. The nuclear-powered reconnaissance drone can operate indefinitely. But attack drones must have conventional engines. Unlike nuclear reactor-based technology. 

The RTG is suitable for high-flying stealth drones. They don’t leave a radioactive trace behind them. Those drones don’t need oxygen. The nuclear-powered drone can fly at very high altitude. Even if aerodynamic controls don’t work. The drone. It can glide to lower altitudes.

The larger-sized drones can carry smaller drones. And the new tools are the underwater drones. The underwater drone can conduct reconnaissance and intelligence missions in enemy areas. Those drones can also protect larger submarines. When we think about underwater. Long-range nuclear torpedoes. Those weapons are not always 50 megaton-class. The 10-15 kt warhead . It makes it possible. To create an unmanned system. That fits into the torpedo tube. 

Small unmanned drones can escort larger submarines. When something threatens those submarines, those underwater loyal wingman drones. They can attack that threat. Those drones. They can use hydrogen-oxygen. Air-independent power sources. That system uses bottled hydrogen and oxygen in its power cells. 

And they can carry other drones. Those drones. They can make operations into hostile harbours. And then they can cause damage to the larger vessels' hulls. In the case of submarines, even a small hole. In its pressure hull can turn devastating. In the same way. Stealth aircraft, along with supersonic- and hypersonic systems. They are more vulnerable than old-fashioned systems.

The world's first superconducting quantum heat engine is real.

“Artistic impression of a superconducting quantum heat engine. Credit: Heikka Valja / Aalto University”  (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

Finnish researchers have created the first quantum heat engine. “Researchers at Aalto University have built the first cyclic quantum heat engine inside a superconducting circuit. The device uses a qubit, the basic unit of quantum information, as its working substance and repeatedly drives it through heating, cooling, and energy conversion.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“Quantum heat engines have previously been demonstrated with systems including trapped ions, atomic gases, nuclear spins, and defects in diamonds. Superconducting circuits are especially important because they are already among the leading platforms for quantum computing, communication, and sensing. Until now, however, no experiment had completed a cyclic quantum heat engine using this technology.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“The immediate significance is not the amount of work generated, which is extraordinarily small. Instead, the experiment shows that heat can be deliberately controlled and converted inside the same type of circuitry used to build quantum processors.”(ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

Quantum engines are the miniaturized versions of nanotechnology. If those systems. They can put particle spin very fast. When particles spin in the cage. It pulls energy through that structure. That causes a quantum glow in that cage. Basically, a quantum engine; it’s similar to other engines. e It can use the magnetic field and IR radiation combination. To make transform radiation into motion. Those systems. They just transform wave movement. Or electromagnetism. Into kinetic energy. So, when the core in a quantum engine spins. That core binds energy into it. When its speed accelerates. When it slows. It delivers energy. 

“That capability may become valuable as quantum computers grow. Today’s superconducting machines depend on large numbers of microwave cables running between room-temperature electronics and processors kept at temperatures only a fraction of a degree above absolute zero. Each cable adds cost, occupies space, and can carry unwanted heat or noise into the system.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

“The researchers are now working toward a fully autonomous version of the engine. One possible application would be reading the state of a qubit without sending a microwave signal from the cold processor to room temperature. Placing more control functions directly inside the cryogenic circuit could reduce the amount of external wiring required.” (ScitechDaily, World’s First Superconducting Quantum Heat Engine Could Transform Quantum Computing) 

The quantum engine that transforms infrared radiation into motion is a fascinating tool. 

This. Kind of system. It can transform all radiation types. Into another by using motion. The radiation. Like radio waves. Hits the quantum engine. It starts to move. And then. It transforms that movement into electricity. Then that electricity. It can be used. As an example, an X-ray system.

Quantum system. That transforms kinetic energy into motion. That thing can be the new tool for micrometeor and armour technology. If the system can transfer impact energy into rotating movement. That can turn a surface extremely hard. In stealth technology. That ability to transfer electromagnetic radiation into movement. Makes it possible to pull standing waves out from space between atoms. Those systems. 

This kind of system. They can feed energy to quantum computers. The system. That can transform radiation into motion. This can bring interesting ideas for energy sources. To the journeys to the edge of the solar system. The quantum engine that can turn minimal energy into motion is the thing. That could replace at least some of the RTG (Radio Thermal Generators). Used in long-distance space journeys. Or those systems. They can at least make the RTG power sources more effective. By benefiting from the temperature that those isotope generators deliver. 

Nano- and quantum technology that transforms heat into motion. That is the system. That can help to create more sustainable materials. That stand the heat. The idea is that those quantum systems. They can transfer heat energy from the shell of the spacecraft or airplane into a moving part. This turns infrared radiation into movement. And then that nano-. Or quantum generator. It can transform the heat into UV light. 

This kind of transformation is quite easy to make. The nanotechnical generator. It simply transforms heat energy into electricity. Then that electricity. It can be transferred to UV light. This kind of system. It can transform almost any wavelength into another. When things like radio waves hit this kind of system. That system can transform radio waves into X-rays through motion. This kind of system. They can be the next-generation tools. For new stealth  technology.

AI might think differently than humans.

“York University researchers have uncovered a surprising mismatch between how artificial neural networks and primate brains process visual information. Credit: Shutterstock.” (ScitechDaily, Scientists Discover AI Models May Not Think Like the Brain After All)

AI might not think like a human at all. When researchers try to make computers think like brains. Those people sometimes forget why human brains are so different. Thinking in human brains is more closely connected to physical structures such as neurons and neurotransmitters. Than we even think about. 

This is the big difference between computers and human brains. The structure of the human brain plays a bigger role in the thinking process. Than we thought. The computer that runs billions of databases. It can have a very impressive capacity to connect information. But the problem is that. One binary processor. It can run one operation at a time. The system requires new processors. 

That processor. It can run. Multiple tasks at the same time. This is not possible for the regular processor. But the processor. That mimics the brain. It can use all its layers as independent processors. 

 The brain has four main areas. 

1) Cerebral cortex 

2) Cerebellum

3) Brainstem 

4 Cerebral hemispheres. The last one has two parts. 

The fact is that if we create a microprocessor that mimics the human brain. We need a five-layer microprocessor. Each of those layers can use a different programming language. That denies the data mix in the system. If every layer of the processor uses different languages, that makes data meant for other layers seem white noise.

Each layer mimics each part of the brain. And those layers. They can have different programming languages. Or different frequencies. That helps them to separate and sort information. The four-layer microchip. It can have one divided layer. That mimics the cerebral hemispheres. 

From different sources. The database connections. They can mimic neural networks. That transfer information in human brains. The difference between database structures and human brains is this. Databases run on the same monolithic computer. In human brains. Every single neuron is like an independent computer. This means that if we want to make a computer. 

Or. We can rather say: an AI solution. We must create a system. That involves 86 billon computers. The system. It can use morphing neural networks to make its operations more effective. 

“Schematic of a simple feedforward artificial neural network.” (Wikipedia, Neural network)

The thing that can make the process quite easy is that. Every neuron has. The ability to change its connections and their relations. This means we cannot measure the neuron’s ability to process information in the same way. As we measure a computer’s ability to process information. Human brains store information in the form. 

That is similar to a mosaic. The information. It is stored. In a form that is like pixels. Brains can connect and reshape those pixels freely. And that ultimate flexibility makes human brains so different from machines. In brains, every neuron has a pair. A mirror neuron. The neuron and its mirror. They act like loops or algorithms. Another purpose for mirror neurons. That is. They tell the primary neuron that the information traveled through. 

In human brains.  Multiple points of start. Data processing. At the same time. Brains can spread the operation. They could reserve more neurons for that action. This means that brains concentrate. In another way. Than computers. In brains, in brains. Every neuron acts as an independent computer. And the large number of neurons gives fine-tuning for processes in the brain. 

Computers can also connect data. But that system is far different from humans. In computers. The binary system. It can handle only one task per operation. The AI. That mimics human brains. Must have 86 million physical processors to mimic human processes. The ability to search data and then combine that data with memory. Is the thing that we call thinking. 

We could make a machine. That mimics human reactions. That machine requires a physical platform. That involves the same structure. As human brains. The fact is that. If we want to make a machine. That thinks like humans. We must remember that the system. It is a combination of hardware and software.

What do a locomotive and a data center have in common? They both face resistance.

Political resistance against data centers. Forces them to find new locations for those systems. 

Data centers face resistance. That is one of the things. That we can see. The main problem with data centers is this. Those systems don’t require permissions. Except for the use of land area. The data company. It can buy a large group of houses. And then turn the database into cloud-based systems. The cloud-based architecture means this. There can be extremely large data centers in the neighborhood, and nobody even knows that they are there. 

When we resist data centers. And the use of AI. We can see similar cases in history. In history, people resisted things like cars. The origin of the car is in the train. The steam engine made it possible to make trains. 

The speed of the first train. It was 21 km/h. The crew of the train was two. Two men could handle very much cargo. The first trains were used in mining areas. They could maintain their speed. All the time. And that removed the crew from logistics. And then people started to think about the possibility. To create the train on wheels. The combustion engine made the car real. And that caused problems with workers. Unlike horses. Cars and trains required mechanics. Those people who worked with those mechanical systems required training. Unlike people who feed horses. 

They said cars would cause unemployment. Cars caused pollution. But the first arguments against cars were that cars take work from cattle workers. The problem with that criticism was simple. It was that the critics were cattle owners. Horses were the most important working “tools” before the car. The big problem with cars was that. They took the place that belonged to horses. first car was slower than a horse. The maximum speed of the car. It was about 15-30km/h. But the car was a machine. It could maintain that speed. All the time. So, the car was more effective. The car didn’t need water or food. And that made tractors and cars suitable. To operate in places. Like Antarctica. If people operated there with horses. That required a lot of food. 

But as we know, people resist data centers for many reasons. The big problem is that. The only thing that measures effectiveness. It is the income money. If people have free time. In their workplace. That is ineffective time. That causes a need to decrease the number of workers in the workplace. That causes unemployment. 

Another thing is that. People resist everything that is new. The ICT area is been like in the position of the stepson in the media. When we think about traditional business. That thing required a lot of workforce. A steel factory sends pollution. So that requires lots of permissions. Of course. Data centers require permission to use land area. The data company can just buy a lot of houses. And then make data centers in them. This kind of solution doesn’t need new buildings. This means that. The data centers don’t need as much political support as traditional factories. 

And the second thing is this. Data centers are primary targets for the enemy in the case of war. This means that things like underground facilities can help data center survivability. 

But the answer. It could be an underground data center. The tunnels are full of supercomputers and are not visible from the ground. The technology. That those tunnels require. They can be the same. That is used for making subway trains. 

The ICT company doesn’t require a workforce in the traditional way. They don’t need raw materials. They need people who make code. There are no psychological or health limits in this work. The ICT company just needs working spaces. And remote work makes it possible to operate data centers from another side of the world. The head coder can do the job. That person can operate and train AI agents to make code. The underground facilities are the answer to the natural problems. Data centers that are deep underground. They can use geothermal heat or miniature nuclear reactors to provide electricity. 

The deep caves. Like exhausted gold mines. They can provide stable and radiation-protected locations. Some of those points are used for neutrino telescopes. But those locations can be suitable places for quantum computers. The quantum computer. It can be in a thermos box.  The isolation layer: A faraday cage and radiation protection. They are between the walls. Of the box. The purpose of those layers is to isolate the qubits. From the outside environment. 

The other place where those data centers. They can be made. Is the ocean floor. Large and complex structures. They can be modules. Dropped to the deep sea. Deep-sea data centers can be operated using robots. Underground and deep-sea positions. They can protect data centers against terror and bomb strikes. 

Rising resistance against data centers. Forces data companies to find new positions for data centers. The deep sea and underground positions. They are effective. But things like orbital data satellites are new tools. They can operate using cloud-based architecture. Data satellite. It’s a similar server. To other servers. The orbital server’s program maintenance. It is similar to other servers. So, the person who does the maintenance work. That person doesn’t need to know. The position of the server. The orbital data center. It can be the belt or chain of data satellites. If one of those satellites is visible from a ground station all the time. That means the maintenance will not see any difference between ground-based data centers. And data satellites.  

The satellite. It can have a heat shield. And the ability to land safely. This means that those satellite swarms can recover their critical components. And that helps to find. If somebody tries to “steal” them. The orbital data center. It is a group of satellites. Those satellites can communicate with each other using lasers and radio communication. The system is similar to Starlink. The backups. And other things can be made into other satellites.

Or ground-based hard disks. When one satellite is jammed. That satellite will be replaced with another satellite. The operations with orbital computer platforms are the same as they are on ground-based systems. The people who operate the computers. They drive system updates into the orbital data servers. As they do for the normal ground-based data centers. The people who update and maintain computers. They must not have access to satellite trajectory controls. 

People who adjust satellite trajectories must not sit in the same room. There the compute operators sit. The same way as in every other data center. The maintenance crew can operate those systems remotely. Just like in every case on Earth. The remote operators don’t need to know where their server is located. They need to know how to make those updates. 

Solar sails and their technical problems.

In some ideas: solar sails. They can travel inside the solar system. The idea is that those sails can be very large radio telescopes. Or they could carry large interferometer antennas out from the asteroid belt. 

There are visions of solar sails using laser acceleration. It can travel to other solar systems. When a solar sail travels very fast. Photons that impact the solar sail start to transfer less energy into it. When the sail reaches a speed. About 75% of the speed of light. The laser beam that accelerates it starts to lose its energy. 

The Doppler effect changes the wavelength of the impacting laser beams. The effect is similar. As we were throwing balls to an escaping car. When an object escapes, the particle pushes energy to that object more slowly. And that decreases acceleration. Photons act like all other particles, like balls. When the solar sail moves faster. The laser beam that hits it starts to lose its power. 

The calculations show that low-energy photons can slow the solar sail. This means that when solar sails travel outside the solar system. The same light that accelerated it turns to slow the solar sail. So does light accelerate or slow it down? That depends on the energy level of the photons. 

If the photon's energy level behind the solar sail is higher than its front side. The photon accelerates the solar sail. If that energy level behind the solar sail is lower. Those photons transfer energy into themselves. And that slows the solar sail. But another thing that can slow the solar sail is the gravitation of the entire solar system. 

When the solar sail starts its journey, there is less mass behind it. Than when the solar sail travels out from the solar system, the entire mass of that system turns behind it. This means that the mass of the Kuiper Belt. Oort clouds. And planets, the Sun, and all asteroids start to pull the solar sail behind it. Another thing that can slow the solar sail is the starwind. The starwind is the particle flow from other stars. 

That particle flow impacts. The heliopause from outside it. That can also push the solar sail back. So if that particle flow is stronger than the particle flow from the solar system. That thing pushes the solar sail back. This means that solar sails may need something. That pushes them forward. Those things can be hydrogen bombs that are left in the solar sail’s trajectory. But the problem is always the same. The acceleration means that those systems can push less energy to the solar sail. For the same reason as why the laser beam cannot transfer energy into it. 

When we think about the systems that carry laser systems. The only problem is that. Those systems would form a closed system. The laser system. That shoots a laser beam into the mirror at the front of the craft. It must be released when it is shot. When that laser is released. That system is not closed anymore. And those single-use lasers. They can push the craft forward. The idea is that. The laser is in the frame of the solar sail. Then that system. It will be separated. When the system. It needs the power. 

Those single-use lasers. They can be like in a magazine in the solar sail. Then those systems. They can be released. The laser. It can get its energy from a rocket engine. That pumps energy into it. When the laser is separated, the rocket starts. And it also gives energy to the laser. The rocket pushes that laser system backward. 

The fact is that. Solar sails can be interesting tools. To travel inside the solar system. But stars are always a little bit too far. Inside the solar system. Those solar sails can use solar energy and particle flows. This means that interstellar flight will not be possible until the entire solar system is explored.
