Supercritical fluid

 



Supercritical fluid 


In the beginning, I must say, that water is not only supercritical fluid (1) in the world. Supercritical water or rather saying supercritical fluid is one of the solutions, which might affect climate chancing. The supercritical water is boiled to an extremely high temperature in the very high pressure. That thing can turn the water to the form, which is at the same time liquid and vapor. The critical temperature of the water is 374 Celsius and the pressure 22 MPa, and that thing could make the turbines more powerful and effective if that kind of steam would conduct to the turbines. 


So in this type of high-pressure system, the steam would be replaced by using the supercritical fluid, which is boiled to a higher temperature in the very high pressure, which is upper than the minimum critical point. So how this kind of system is working? The answer is that the circuit, where the water is flowing would have the base pressure, what is very high, and then that water is traveling through the grate. 


The system is similar, which is used in the nuclear reactor primary circuit. In the nuclear power plants, the high-pressure water would conduct to the heat exchanger, where it delivers its heat energy to the secondary circuit. The reason for that is that the primary circuit is touching with very high radioactive elements.  


What if the tubes in the power plant would be closed to the vacuum, which denies the transferring heat to the atmosphere. 


But if that kind of system is used in the normal powerplants, what are using natural gas or maybe in future hydrogen, there is possible to use only one circuit of water. In this kind of system the supercritical fluid, what is boiled in the gas oven would conduct the turbines, and that thing can create more power with less fuel. 


And at this point, I must say that there is no experience with this kind of powerplants and high-pressure water systems. This kind of system can be more effective than normal steam-based systems, because the supercritical fluid is thicker, and that makes gives it more kinetic energy than if the system uses normal steam. 


Another thing that can increase the energy economy of the power plants is to use the thermos solution in the tubes of the power plants. That thing means that every single tube, where moves hot water should be closed in the vacuum. This kind of thing would deny the movement of the heat to the air, and that is another thing, that will decrease the need to use the fuel, and that decreases also the waste.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines.  The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
