An electric jet engine can be the next revolution for aircraft.



 

An electric jet engine can be the next revolution for aircraft.

The electric jet engine means the engine, which will create thrust by using electric arc, and that thing doesn't require the fuel at all. Sometimes also plasma engines are mentioned as electric engines.  In some models, the plasma is formed at the front of the engine, and then the magnetic field will pull it backward. 

But the term "electric jet engine" means an engine, which uses only electricity to make thrust. So the systems can use plasma, but they can also be more traditional-looking engines, which are using electric arcs in the combustion chamber for creating the pressure, which is normally created by using the burning fuel. 

Or the thrust of the engine can increase by injecting water or hydrogen in the combustion chamber, which allows the aircraft, what uses this kind of system fly to the orbital trajectory. In that case, the engine compressor will be closed by using a hatch, and the hydrogen will inject into the combustion chamber. 

The electric jet engine needs electricity to create the electric arc, and sometimes people think that this thing requires a nuclear reactor. But there is a possibility that this kind of aircraft can charge its battery wirelessly by using powerful radio waves. 

The high-voltage chemical batteries can be the high-voltage capacitors, which are cooled to a temperature that is quite near the zero kelvin degrees. The electric jet engine can be the system, what is used in the next generation small-size spacecraft, what is diving to the atmospheres of the giant planets and their moons. But those engines can also allow that the aircraft or drone can fly even weeks if the electric supply is confirmed. 

The electric storage capacity of that kind of aircraft can increase by installing wind generators and solar panels on the wings and in the body of the craft, and that thing can improve the operational range. The aircraft cannot be a perpetual motion machine, but if it will rise to the low Earth orbiter, the batteries of that system can load by using solar panels, and that thing gives those engines a very high capacity. 

Also when the craft will dive into the atmosphere it can load the batteries by using windmills, and that thing would make the electric jet engines more powerful and multipurpose tools than any engine before. Maybe this system is not ready yet, but it can be the engine of tomorrow.

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...
