What is vactrain concept?
The vactrain is a magnetically levitated or magnetically powered train system, which operates inside the evacuated or partly evacuated (air-less) tubes. The concept of vacuum tube transportation was first proposed by Robert Goddard, the father of modern rockets, in 1904 [1].
What is vacuum tube travel?
A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. Reduced air resistance could permit vactrains to travel at very high (hypersonic) speeds with relatively little power—up to 6,400–8,000 km/h (4,000–5,000 mph).
How is Hyperloop different from Maglev?
This Virgin Hyperloop test hit a top speed of just 48.07 meters per second, that’s 107 mph and it traveled 395 meters. Hyperloop is effectively a magnetic levitation (maglev) train in a vacuum tube. As its name suggests, maglev technology suspends trains in concrete tracks using electromagnets so it’s floating on air.
Why do maglev trains travel in tubes?
Some systems (notably the Swissmetro system) propose the use of vactrains—maglev train technology used in evacuated (airless) tubes, which removes air drag. This has the potential to increase speed and efficiency greatly, as most of the energy for conventional maglev trains is lost to aerodynamic drag.
How does a vacuum train work?
In a vactrain system, a magnetically levitated train moves through a vacuum sealed tube. The vacuum means no air resistance, and the magnetic levitation means no resistance from wheels or tires. Second it means that the amount of energy required to move the train is very small.
Where are maglev trains used?
While the maglev technology has been developed and touted as the future of train transportation for decades, there are only a handful of countries operating maglev trains around the world: China, South Korea and Japan.
What is Tesla hyperloop?
Hyperloop is an ultra-high-speed ground transportation system for passenger and cargo proposed as a concept by Elon Musk, CEO of Tesla and SpaceX, in a white paper back in 2013. It consists of partially evacuated tubes and passenger or cargo pods moving at very high speeds.
How fast does Elon Musk train go?
But the hyperloop theoretically could bring passengers from city to city in less than 45 minutes, traveling at the top speed of 760 mph. The concept gained popularity in 2013 when Elon Musk wrote his Hyperloop Alpha paper.
Why is hyperloop better than trains?
According to Elon Musk, hyperloop can transport people and freight at up to 750 miles per hour, which would make it 2-3x faster than bullet trains. The pods won’t have wheels like cars or conventional trains. They will float in the low-pressure tube using magnetic levitation.
What kind of train is the hyperloop?
A hyperloop, as you may have heard, is a super speed ground-level transportation system in which people could travel in a hovering pod inside a vacuum tube at speeds as high as 760 mph (1220 km/h), just shy of the speed of sound.
How do electromagnetic trains work?
In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other. Here, both magnetic attraction and repulsion are used to move the train car along the guideway.
