Solar sails that use laser beams to accelerate their speed are the new tools for space technology. The regular solar sails use solar particles to accelerate their speed to high enough that they can travel to the Kuiper Belt and beyond. The solar sail can take extra energy from laser beams that are shot from ground or orbital laser systems. In some ideas, lasers that accelerate spacecraft can be in stable positions in the solar system.

There, they shoot laser beams at spacecraft when they travel past them. Those lasers can use solar power. But in longer distances, they can use nuclear power in so-called YAG technology, where acetylene light there, acetylene burns in pure oxygen and gives light to the laser elements like flash tubes. That means the high-power lasers don't need nuclear reactors. 

That is one variant of the Medusa drive. The solar sail that the nuclear bombs accelerate. In some variants, the nuclear bombs will be sent to certain points in the solar system. When sail travels past them, those hydrogen bombs will detonate. 

The laser system can also connected to the spacecraft itself. The high-power wireless electricity transportation can solve the power-source problem. 

Then, the solar sail is put to the front of the craft. A laser system can push that craft ahead by sending the laser beams to the sail. The laser gives a very weak thrust if it is aimed backward. But if the laser shoots forward to the sail, that is ahead of the craft. That kind of system can be a new tool for space research. 

The solar sail can also operate as a radar system in that kind of spacecraft. The lasers are connected with solar-sail technology, which makes them quite fast. And they can travel to the Kuiper Belt. Maybe some of those systems find the planet X. 

The searchers can use things. Like ultra-accurate atom clocks to measure the changes in time dilation. Those systems can uncover the gravity effect. But those systems must get to the Kuiper Belt. 

In some models, the land-based laser systems can also raise solar sail out from the atmosphere. The idea is that the solar sail can be connected to the parachute-shaped wing. And the laser systems can push those things out of the atmosphere. This technology is not new. In some models, the parachute or the hot air balloon hangs the spacecraft. In some versions, the laser can create the plasma in the asbestos bag that makes the system look like a hot air balloon. The laser system can be in the rocket. 

The problem is that those systems must be very big. They must share the heat energy to a large area so that the laser will not burn a hole in the system. Another way is to use some liquid gas that keeps the temperature low in the balloon or parachute. That lasers push upwards. 

The hot-air balloon or even hydrogen balloon can raise the spacecraft like a small shuttle over the atmosphere. The hot-air balloon can fly out from the atmosphere if the system has an internal oxygenizer. That means the system can operate like a rocket engine that operates oppositely than normally. The system can basically be the acetylene-oxygen welding system that pushes the asbestos balloon upwards. The hot exhaust gas can push the balloon forward. 

The hydrogen balloon can use mylar, and it's like an Echo satellite, which was also a balloon. The pressure decompression ventilation can remove pressure, and that makes the balloon useful. 

The test with laser-powered spacecraft or laser-powered spacecraft models began before 2010. In those systems, lasers make a plasma that raises the craft to high altitudes. In some versions, the lasers are put in the spacecraft, and they are aimed at the carbon fiber stick that makes plasma in the chamber. The system can offer very cheap and silent propulsion to spacecraft.

Lasers revolutionize particle acceleration can revolutionize technology.

 The laser-accelerated hyperenergy particles can make things like antigravity possible. The idea is that high-energy particles or radiation can make things called "gravitational redshift" possible. The antigravity system should only stretch gravitational waves. And that kind of system can really remove gravitational effects. But the problem is how the system can make that thing. One possibility is to use some particles with hyper-high energy levels. 

Laser acceleration is a fundamental thing. The difference is that lasers can accelerate also particles that have no polarity. Because laser rays can accelerate neutral particles those systems can make things like neutrino beams possible. The idea is that the system pushes neutrinos using laser rays. And that can make new observation tools possible. The laser-accelerating particles can also make fundamental aviation and space flight tools possible. 

Laser beams can increase the particle's energy to an enormous level. The Berkeley acceleration system made an impressive record using laser accelerators. "Using dual lasers and an advanced gas injection system, researchers at the Berkeley Lab Laser Accelerator Center (BELLA) accelerated a high-quality electron beam to 10 billion electronvolts (10 GeV) over a distance of just 30 centimeters." (ScitechDaily, Lasers Unlock the Next Frontier in Particle Acceleration)

"Record Energy and Beam Quality: Researchers used a petawatt laser to accelerate a 10-GeV electron beam, marking a major improvement in both energy output and beam quality." (ScitechDaily, Lasers Unlock the Next Frontier in Particle Acceleration)

"Advanced Experimental Setup: The new system features precise plasma control, allowing scientists to observe how the laser plasma evolves throughout the process. (ScitechDaily, Lasers Unlock the Next Frontier in Particle Acceleration)

"Dark Current-Free Acceleration: By eliminating background electrons that can sap laser energy, the setup efficiently channels power into the intended electron beam." (ScitechDaily, Lasers Unlock the Next Frontier in Particle Acceleration)

Maybe the craft that uses laser accelerated ion engine looks like this. (Artist's impression) The ion beam drives atoms to the ground. And air that comes from the sides keeps the system hovering. 

It's possible. That the antimatter spacecraft can look. A little bit like the Skylifter airship. The crew module would be in the rotating saucer, and the antimatter cathode engine must be far away from the crew and instrumental areas. In that engine, the positrons and electrons annihilate with each other. 

The high-power laser systems can create new applications. For civil and military purposes. Researchers created an idea that they can use laser-accelerated electrons in antimatter production systems. 

The laser shoots those electrons against the thin gold plate. And that can turn those electrons into positrons. 

The antimatter systems can make things like the most horrific weapons like Teller bombs or antimatter bombs possible. The laser system can accelerate cathode rays and then that thing can form antimatter. That is one of the most destructive inventions in history. 

But the laser-accelerated electrons make things like antimatter engines possible. The high-energy cathode rays that the system turns into antimatter can react with positrons and hydrogen or water. That system can give an enormous punch to spacecraft. This system can make spacecraft travel all around the solar system. 

The annihilation makes it possible to create fundamental levitation systems. In antimaterial levitating crafts, there is a chamber where the annihilation happens. The roof is denser material and the bottom is material that lets energy travel through it. That makes asymmetry that gives thrust to the system. 

But laser-accelerated ions or electrons can have the ability to make saucer-shaped craft hover. The laser beam makes the low-pressure channel through the air. And that channel pulls the air from around the craft under it. The laser-accelerated particles can create virtual antigravity levitation. Those ion engines can give very high-speed specific impulses for ions and electrons even if they are not used in antimatter engines.
