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

(Picture 1)

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.

MIT's tractor beam can make the new types of SASER systems possible

"This chip-based "tractor-beam," which uses an intensely focused beam of light to capture and manipulate biological particles without damaging the cells, could help biologists study the mechanisms of diseases."(Interesting Engineering, MIT’s Star Wars-inspired ‘tractor beam’ uses light to capture, manipulate cells) MIT's tractor beam can make the new types of SASER systems possible. The tractor beam just hovers the nanoparticle in air or medium, and then the laser or some other electromagnetic system transports oscillation into those particles. The ability to make cells and other particles hover in the system makes it possible to create particles whose energy level or resonance frequencies are accurately calculated things. That thing makes it possible to create things that transmit wave movement accurately and cleanly. This is one version of the use of a tractor beam. Modern tractor beams are like acoustic tweezers where sound waves lock the object in its cr

The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible.

That could make gamma-ray lasers possible. The process has been observed by the NASA (Lockheed) ER-2 research plane, which is a modified U-2 spy plane. The gamma-ray formation in thunderstorms. Where lightning and electric fields release electrons that impact the air molecules and water droplets is an interesting thing. That thing opens the route to solving many mysteries. "The general physics behind how thunderstorms create high-energy flashes of gamma radiation is not a mystery. As thunderstorms develop, swirling drafts drive water droplets, hail, and ice into a mixture that creates an electric charge much like rubbing a balloon on your shirt. Pos

Chinese innovations and space lasers are interesting combinations.

(Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th
