The problems of DEW (Directed energy weapons)

The major technical problem of direct energy weapons like laser guns is overheating. The laser element rakes very much heat, and that's why it must have an effective cooling system. That's why navies of the woŕld are the first users of laser guns. Ships are rounded by sea, and seawater can be used in cooling systems of laser weapons.


Those Laser guns are the same type of lasers that are used in metal industry, and most of them are carbon monoxide lasers, what give extremely powerful radiation in the infrared area of the electromagnetic spectrum. Naval laser systems are working as a replacer of a normal anti-aircraft cannon. They simply cut off wings of attacking airplane. The problem of gas lasers is it is a tube filled with gas, what makes it a little bit hard to install to portable systems. Gas leak in the tube causes malfunction of the system. But why military men around the world are interesting with lasers?


The reason of developing of that kind of systems is that laser has limitless ammunition capacity. If a soldier uses laser gun he doesn't need any ammunition at all, and that makes laser very effective if it works.  Only thing what the user of laser gun needs is light to laser element, that the weapon will work. If we are talking about the problem of laser rifle, the major problem is that laser element must stand for strikes and hard handling. The problem with that limitless ammunition capacity is security. If laser gun goes to wrong hands, the problem is that those men don't need ammunition.


They must only get acetylene for that gun's YAG systems acetylene lamp, and after that, they are free to shoot. That causes problems with public security because nothing puts limits to shots. And that is a very bad thing if those weapons go in wrong hands. And if those weapons are used in criminal actions, the user can't be tracked by rifle picture on bullet or DNA what leaves to patrons. That will make those weapons extremely dangerous.

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...
