In the film "Kin-dza-dza" there are many analogies with Soviet reality. But as for the technical inventions of the future, many look comical. Take, for example, gravitsapu. What it is? Interplanetary ship detail or perpetual motion machine? Without it, it is impossible to make instantaneous movements in space, but you can fly in a linear plane.
It is known that even with a gravitapa it is impossible to reach the galaxies of Antitentura. So, it does not work as a universal tool for any movement.
Moves in violation of the laws of physics
Interest in the perpetual motion machine has always accompanied humanity. In the twentieth century, this term, as morally obsolete, was replaced by "unsupported mover." And even several models were created that demonstrated receipt of traction as if from nothing.
It is generally accepted that the engine creates energy, runs on one of the types of fuel, and only such a device is worthy of bearing this name. The theoretical propulsion system only converts energy without coming into contact with fuel, and is a closed system. Since there is no scientific evidence for the existence of such a device, they speak of models similar to it.
These are space sails, engines of Woodward, Bassard, photon, subwarp, dark and electromagnetic.
Inertioid
Another name for an unusual device is an inertioid. This is a mechanism that creates traction by moving its parts. For example, the inertioid Tolchin is known. This is a mechanism whose action is due to several physical laws. It includes special parts and springs. There is a whole classification of their types: with various loads, levers and other moving parts.
Official science does not recognize the possibility of creating a real inertioid. Despite this, many enthusiasts are obsessed with the idea of ​​creating an operational model. Why is there so much interest in inertioids?
The means of transportation of almost all the means created by man are based on the use of support. It is a solid surface, water or air. And in space, jet propulsion is created by burning fuel, which quickly ends. The idea of ​​creating an apparatus that would not discard part of itself to create movement, and became inspiring for the authors of inertioids.
Gravitsapa as a perpetual motion machine
If we put aside all physical laws and dream about a fuelless spaceship, then we can come to the following justification of the gravitsapa:
- Field theory, as well as other laws of the branches of quantum mechanics and nuclear physics, are not violated at all during its operation. This means that in local interactions, whether molecular or atomic, both energy and momentum are conserved. Regarding entropy, the question is not worth it - it is moved beyond consideration.
- The unsupported force generated by the gravitsap is created by a multitude of pulses, which add up to a certain number, for which the axioms of arithmetic are still preserved. This is a hypothetical Mizugadro number. It has been proposed since 2010 as an example of violation of the law of conservation of momentum.
- If the principle of relativity is observed, then the phenomenon of impaired conservation of momentum of the apparatus under study proves the existence of the Misugadro number.
If experimental studies confirm the work of the gravity caps, journalists are ironic, then scientists will finally prove: pulling yourself out of the swamp by the hair is quite real. No wonder R. Raspe described a similar case with Baron Munchausen. Galileo's principle of relativity does not contradict the fact that the gravitap is such a variant of the perpetual motion machine. But let's move on to our time.
Gravitsaps of the twenty-first century
Space devices that can move without ejecting a working fluid are now referred to by the term "gravitapa" with the light hand of the filmmakers. What is it, the developers of the device know. True, they argue that there are more effective options for propulsors. But the term invented by the director Danelia is very good.
The employees working on the creation of such ships are sure: it is necessary to achieve the direction of the vehicle’s thrust against the direction of rotation of our planet. Then the speed of its braking will be a huge figure of the order of 10 6 meters per second. At the same time, little effort will be enough to get unprecedented power in megawatts.
NPC Khrunichev experiment
Since 2001, work has been underway under the auspices of space research to create a working model of the perpetual motion machine. For one of the developments, a certificate was issued about the invention of a device that can convert the rotational moment to translational.
On the Yubileiny satellite, experiments were carried out to develop a team of scientists bearing the working name Gravitsapa. The goal was to achieve a change in the parameters of its orbit. By means of an inertioid, it was not possible to achieve any changes in the satellite motion parameters.
In an interview for the media, the head of the institute V. Menshikov substantiated the theory of the apparatus, adding that tests had already been conducted on the ground. He, in particular, spoke about the principle of the device. It works due to the movement of a certain substance inside it, which can be liquid or solid and imitate the trajectory of a tornado.
Chinese bucket-like counterpart
In September 2013, the media published sensational information about the Chinese non-inertial propulsion engine EmDrive. At first, it caused irony with a primitive construction. It was compared to a truncated bucket and was also called a gravitsapa. What is it, not in words, but in fact explained by the Romanian inventor Birch Julian. He soldered the same working device at home.
The device has a so-called magnetron, through which microwaves are created. They create vibrations. Those, in turn, have a small energy that accumulates in the resonator. Then it is converted into traction. The creators argue that this does not use fuel and there is no jet emission. EmDrive was also tested under vacuum, as NASA gave a detailed report. The reaction of Russian scientists is mixed. Along with a critical attitude, there are also positive reviews.
Commentary by a Russian scientist
An employee of the Russian Academy of Sciences G. Malinetskiy does not consider the scientific development of such devices to be miracles or quackery. There is an unusual phenomenon that needs to be studied. Conflicting hypotheses regarding the principles of their work have already been created, and some even reconcile them with Newtonian physics.
The bottom line is to turn the energy of the electromagnetic field into the energy of motion. American colleagues already have samples that successfully operate in experimental conditions. Now China has tackled this problem. In Russia, similar work has been carried out for many years, but the progress of the study is not covered.
The scientist believes that the use of such devices is relevant in space. For example, in order to adjust the satellite’s orbit, extremely expensive fuel is expended due to the delivery from Earth. With the help of an apparatus that does not need fuel, this is convenient to do.
Gravity Cap Features
It sounds fantastic, but the capabilities of the inertialess propulsion system are enormous. With built-in heavy duty magnets, it will be possible to create flying cars.
The spaceship will be able to reach speeds a thousand times faster than now. Traveling to Alpha Centauri will take about a hundred years.
Flights in the solar system can do without fuel. To generate microwave radiation, solar panels are enough. For long distances, thermonuclear reactors will be needed. Work in this direction is already underway in Russia.
Conclusion
It has already happened more than once that science fiction writers have become prophets. The terms and principles of operation of some devices described in the novels later became part of the life of a modern person. So it was with Isaac Asimov's robots and laws of robotics, William Gibson's cyberspace and John Campbell's force field.
The film “Kin-dza-dza” became another prophecy. Maybe soon scientists will make a real discovery and create the same gravitsapu?
