The metal-fueled rockets can use to conquer our solar system.




Metal-fueled rockets are one type of the ion engine. Or they use the same method to create thrust as ion engines. The metal rocket uses metal vapor that the magnets drive backward. In space or inside the asteroid belt the system can get its energy from large solar panels. And outside the asteroid belt, the miniature nuclear reactor can give electricity to that system.

In that kind of system, the long solar panels can also be used as a cooling system for the nuclear reactor. The metal engine can also use another material that it vaporizes. The metal engine can use magnetic metals as neutral atoms, which it drives through the acceleration track. But it can use ions and also things like water or hydrocarbons. In the last cases, the system ionizes material that travels through its acceleration track.

Or it just raises the material temperature to make it expand. In those systems, the electric arc or some other electromagnetic radiation replaces combustion and causes the expansion of the fuel. 

The idea is that the laser or microwave systems vaporize metal powder, and then a magnetic accelerator drives that high-temperature metal vapor through the acceleration track. The laser system can shoot its beam through that metal vapor to increase its speed and thrust. The metal vapor can also used in "normal rockets". The system must only vaporize metal in the "combustion chamber" or this case expansion chamber. 



Can this kind of rocket travel to space from launchpads on  Earth? 


The expansion of the metal vapor causes a similar effect to burning fuel. The system can pump the air to that chamber to increase thrust and keep the temperature low. In some theoretical versions, the system uses metal wire that feeds into the burning or expansion chamber. The laser, electric arcs, and/ or, microwaves will vaporize that metal. Then the system injects things like liquid gas into this heated metal wire. 

And the only problem is the power source. The electric vaporization system requires energy. In some crazy ideas, the system uses a laser that is installed in the launching pad. Then that laser will be shot into the combustion chamber. The wireless electric transfer system will transport energy to the rocket using coherent radio waves. 



The opposite operating engine. 


In some cases, there are discussions about the metal vapor or metal ion engines that blow particle flow forward. The idea is "stolen" from the cartoons, where the hero blows air to sails using a propeller or bellows. The ion or magnetic system blows particles into the shield or "sail" ahead of that craft. 

The idea is that the system can fix the ion engine's weak thrust. In some cases, there are plans to use steam. That is created from hydrocarbons or water ice. The metal engine requires a higher temperature, but the system works with a similar principle. It vaporizes metal that acts like a propellant in other rockets.

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
