Vacuum Trains: The Future of Transportation

 


   "With this technology, you can travel from Los Angeles to San Francisco in just 45 minutes".

   Does that sound too good to be true? If so, get ready to be thrilled. In this article, you'll discover how Vacuum Trains can make this become a reality.

   It might surprise you to know that the idea of vacuum trains appeared more than a century ago. It was introduced by an American engineer Robert Goddard in 1904 who produced several prototypes of these trains. Elon Musk in 2012 reiterated this idea even though he now called them "hyperloops". When it is finished, a hyperloop will travel as fast as 800mph. Some of the companies dedicated to the revolution are: Virgin Hyperloop, Hyperloop Transportation Technologies, Transpod, Arrivo and so on. It is absolutely right to say these ideas are out of the paper and are becoming a reality as he first ride in a hyperloop occured in November 2020. It was conducted by Virgin Hyperloop with just two of their employees onboard. Here is a video clip of the ride:

 
    The mode of operation of vacuum trains is based on the principle that moving an object through a tube of  low pressure will increase its speed. Going by this fact, vacuum trains which look more like capsules in sci - fi movies are transported through a tube with all the air evacuated leaving a vacuum making it possible for them to move at very high speeds. These tubes have vacuum pumps ( which should be at most 30 miles apart ) under them which help to pump out 99.9% of the air in the tube. At the start of a journey, the train would first travel through some air locks which helps to reduce more and more of the air pressure in the tunnel after which it can now achieve its highest speed which could be as high as 2500 mph(4000km/h). One way to make this trains travel even faster is to use "magnetic levitation" - allowing the trains to move over a bed of permanent magnets thereby reducing the friction even more. Some trains were produced in Shangai and they work solely on this principle giving them the name "Maglev Trains".

   It is mind blowing to think that if these tubes could be laid under water, it would be possible for an individual to live in one country and travel to work in another country every single day. Even though there are many adjustments that still need to be made before this high-speed trains can fit into the global transportation system, we can be confident that very soon, we will be able to get rid of all the transportation problems facing us today.

       The Consumer Electronic Show (CES) was held this month at the Las Vegas Convention Center in Winchester, Nevada, United States. This event typically hosts presentation of new products and technologies in the Consumer Electronics Industry. Here are some of the most important highlights from this year's edition.   iVision Dee Concept Car               BMW unveiled a wild color-changing concept car with 2600 panels that can change up to 32 colors. During a demo, different parts of this car including the wheel covers flashed in varying hues and swirls of colors. The technology which relies on panels that receive electrical impulses isn't ready for production. On the outside of the car, you could spot breaks between panels and what looked like wiring.   Bespoke AI Oven     If you think taking photos of your meal for Instagram is overdone, now you can livestream your dinner as it cooks in real tim...
