Tesla’s electric power for the truck and the use of electricity in heavy-duty transporting

Tesla has made history, and build brand new concept for heavy-duty vehicles. In that vehicle is electric motors for driving the truck forward. Making of the electric truck is nothing that is made with passenger cars. The needed parts are of course bigger, but technology what is used is tested in many smaller vehicles. And the major problem of electricity usage in heavy transport systems is that the battery’s power would go down, and in the short term driving, there would be no time to recharge those batteries.


The electric system is very useful in heavy-duty vehicles because it can give also the trailer capacity to operate as the part of the pulling system. In normal vehicles, the wheels of the trailer are not connected to the motor system, and that makes this kind of heavy-duty vehicles to operate on bad roads. If the trailer’s wheels are used in driving sequences, and they are equipped with motors, that would make the trailer more capacities than before.


There are two ways to make the truck with electric motors. One is to use the pure electric system, but that would need recharge stations. But in this case, the normal power voltage cable could give the needed electricity for that system. Another is to use the diesel-electric system, where the diesel motor would use generators, and the electric power would be transfer to the electric motors, what is installed in every wheel under this vehicle. This would give the car or truck extreme high speed, and the limit of the speed is the endurance of electric motors. That kind of truck can, in theory, leave even sport scars behind them.

The electric driving system can be used selectively. When the batteries are low, the computer would activate the diesel-system. And in the short drive, there could be used only electricity. This means that the tank of the vehicle must not fill at all if there would be found recharge points on the road. In this system is able to use solar panels for increasing the capacity of the battery. Those diesel motors are meant to use only in the forests, where will not found the recharge points. But this kind of vehicles can use also normal power plugs to reload their batteries. So if this project would be the success, the heavy transportation would be more economical and kindly for the environment than ever before.

What makes recycling scuba-diving equipment so radical?

The problem with maritime operations are bubbles

The idea of the scuba diving equipment, what recycles air thru the active carbon filter would not be new. It bases the idea of the submarine, what would use the diesel-motors under the sea, without the need to use the snorkel. This equipment is known as closed cycle diesel system, and the idea of this thing is that exhaust gas from the machine would be driven thru the active carbon filter.


This filter would separate the carbon from the exhaust gas, and then this submarine could operate a long time before it must get back to surface. In the tests what the Soviet Navy made in 1950's the filter filled with carbon dust, and that caused the bad situation in the boat, because exhaust gas was polluted the air in that submarine. The better systems have particle filter, what would give extra time to use the carbon filter.


The scuba diving equipment what uses so-called closed cycle is the very revolutionary invention, and it has many advantages in comparison with so-called ”open cycle equipment”. The closed cycle means that this equipment recycles the air thru the active carbon filter, what separates oxygen from the exhausted air. And in theory, this kind of equipment could be the only tube, what has the ventilation system, what allows the gas movement to only one direction.


When exhausted air moves thru the active carbon filter, that would make this air cleaner. If this system is only the tube, that gives change to make extreme lightweight scuba diving systems. Those systems are also suitable in the work at radioactive areas, because this kind of system, what don't take air from outside are also denying the ionized Helium pass the filter, and travel to lungs.


This equipment was created for naval scuba divers for long-term operations, but it is suitable in any naval special operations, because the structure of that system eliminates the bubbles, what would uncover the scuba divers, who enter the harbor area. That kind of equipment would also use in space suit and space station air can be cleaned by similar filters, what are used in this kind of closed cycle diving equipment, because it allows astronauts to operate very long time in space. The carbon filter or chemical allows the spacecraft fly extreme long time, and also if that equipment is in the space suit, that would allow the astronaut operate very long time.


If the closed cycle system would be installed in the space-suit type suit, that would allow the diver even sleep in the suit. This would be very important if the person must wait for rescue capsule when the space station would be critically damaged, and the crew must be in space suits. Or it would give change to continue the long-term diving in the deep sea.
