Electric vehicles of tomorrow

Electric vehicles of tomorrow

Hydrogen production in the vehicle can revolutionize the traffic. 

If we would produce the hydrogen for fuel cells in the car, that kind of vehicle can be operated in the highways of the future. In this case, the electricity for electrolysis can be taken from the socket, and the car can use fuel cells or batteries optionally. And those fuel cells would make the operational radius of the vehicle longer, and that thing can be the hybrid car of tomorrow.

We can think that the combination of electric- and hydrogen operating car is one of the most interesting choices, what we can think. If we would tank the car by using water and then scatter it to hydrogen and oxygen in the car, we might have a suitable vehicle, which has no pollution. But there have been many other attempts to create a car, what doesnät need external fuel during the history, and many of them are basing the use of the electric motors. 

Systems what base the difference of pressure or muscle power

One of the most interesting things in electric vehicles is that they can produce their electric power without external fuel. In some cases, there are two chambers in the car, and in another would be the vacuum. If between those chambers is the generator, what is connected to the turbine, and the air or some other material like water or alcohol would float between those chambers, the vehicle can create its own electric power. 

And of course, the vehicle can be equipped with the dynamo, which can be used by similar pedals that are used in the bicycles. The thing is that using gear, the rotating speed of the dynamo would be very high, and that allows creating the electric power, which can use in the small compressor. 

That system needs less power than loading the batteries, and it can be used to create the vacuum to another camber. Then the water floats to another chamber and loads the batteries of the cars. And the driver can change the chambers when another chamber is filled. The thing is that the system can also use the compressor, which is connected straight to pedals. And that kind of system would be quite an interesting thing because it is not addicted to the weather. 

And of course, the car can be equipped with solar panels, lightweight wind generators, and they can load their batteries from the floating water. The thing is that dynamo, what can be used in that kind of operations will be very small, and composite materials would make things like propellers lightweight, and the lightweight materials can also be used in the gearboxes. 

That would revolutionize the driving if that kind of system would someday come to markets. And the thing is that those lightweight materials would make the system very light. But what is the real reason, why we haven't got electric cars before this day? There is no explanation for that, and maybe the reason is that those cars would not seem so pleasant than cars, which are using normal fuel. The explanation is normally that the loading of the battery is taking too long.

Short writing about the electrodynamic rocket propulsion

Short writing about the electrodynamic rocket propulsion

There is no need to use nuclear energy in ion motors, the electricity is enough. 

Sometimes we are forgetting the thing, that ion motors, and other electrodynamic rocket motors like rockets, what are used an electric arc to create the thrust would not need actually the nuclear reactors to operate perfectly. When we are thinking about the replacement of the nuclear reactors, we can use the fuel cells to create the electricity for the motor. In fact, the rocket can be hybrid, what operates in the inner solar system by using the solar panel, and turns to use other ways to produce energy, when the sunlight turns too weak and if we are talking first about the electric arc rocket.

The fuel cells or turbo-generators can use hydrogen and oxygen for creating the electricity for electrodes, which is creating an electric arc in the combustion chamber. In the last case, the turbine would install in the route to the combustion chamber, and the exhaust gas, what is water would conduct in the rocket motor, where it will get extra heat from the electric arc. I don't know how practical this rocket will be, and the fuel cells would act more surely because there are no moving parts in this way to produce electricity.

The electric power can be created by using power cells. 

Then the water what is creating in that reaction would conduct in the rocket motor, what will give a very powerful punch. And this kind of fuel cell system can be used in with ion motors. The ion motor is the motor, what uses ions to give the thrust, and in some speculations, this motor would use metal ions, what will drive through the magnetic accelerator. But the ion motor is one of the most capable systems in the world.

That motor can use every ion in the world, for creating the thrust. And also the hydrogen ions can be used in that system, and in fact,  there is nothing matter, if the motor uses positive or negative ions. The system must just turn two electric wires to the opposite way, what would turn the accelerator work in another way, if the ions, what would travel through the accelerator track.

The system needs only the electricity for operating, and that electricity can get from power cells, turbo-generators or solar panels. And that hypothetical spacecraft might use solar panels in the inner solar system, but when the sunlight turns too weak, the system would transform to use fuel cells, as I wrote at the beginning of the text.
