How hypersonic missiles work?

Hypersonic missiles are the fastest man-made cruise missiles in the world. The function of those weapons is normally, that ballistic missile would take those weapons to the ballistic trajectory, what allows enough speed, that the hypersonic ramjets would be launched, and those motors would give this missile the speed of Mach 12. But there are many problems with those missiles and USAF X-51 "Waverider" failed, and it couldn't start it hydrogen scramjet-motors in 2012.


The hypersonic cruise missiles are new kind of weapon, what is extremely dangerous even without the nuclear warhead. The kinetic energy of those missiles is extremely high, and if that thing hits any target, would the result be devastating. Also, the defense against those weapons is extremely difficult because the angle of incoming missiles is so variable. The nuclear warhead is of course very devastating things, but the hypersonic missiles are devastating without explosives.


Many states have the similar projects, and the most devastating version of those missiles is the nuclear-powered missile, where the burning process of fuel has been replaced with the nuclear reactor. This missile has extremely high speed and because of its big size, this weapon can cause more destruction than any existed weapon ever before. The hypersonic speed allows using the pressure blast of those weapons as a weapon.


The hypersonic flight allows to use the pressure spire as the weapon, what might make the track anywhere this weapon flies. That would give this devastating cruise missile extreme devastating capacity. The big size nuclear-powered missile can use hydrogen or water as the fuel. In this solution, the fuel would be injected into the reactor, what would give very powerful specific impulse. This kind of nuclear ramjet is not very sharp about the propellant, and the idea of this motor is, that the propellant and high speed would also cool the reactor, while this missile will travel across the airspace.


But the problem of those weapons is radioactive fallout. The radiation of the reactor would change the material, what travels thru the reactor also radioactive. That's the very bad problem with nuclear-powered aircraft. In the Cold War were many projects, where were investigated the use of nuclear power in many roles like in automobiles and aircraft. The best way to use nuclear reactors in aircraft is to use closed-cycle reactors, where the reactor would use to rotate the turbines. And the propellant would be heated by using electric arc. This would not deliver radioactive fallout into the atmosphere. But this is the only rumor and those test planes are highly classified.

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
