Hyperloop Transportation: Faster than a Plane and a Bullet Train
The world is getting better and better with the help of science and technology, another great idea proposed by Elon Musk(Founder of Tesla Motors and SpaceX).
Elon Musk is no stranger to futuristic ideas as a Silicon Valley entrepreneur pushing electric cars and private spaceflight. But his latest vision for travel may be the wildest of all — a speedy commuting system several times faster than a bullet train and twice as fast as an aircraft.
The “Hyperloop” idea came up during a sit-down interview Musk had with PandoDaily. Musk, founder of Tesla Motors and SpaceX, described the possibility of going from downtown LA to downtown San Francisco in under half an hour and for much cheaper than airline tickets or other forms of transportation.
The “Hyperloop,” a hypothetical high-speed transportation system that could shuttle people between Los Angeles and San Francisco in only 30 minutes, just sped a bit closer to reality.
First proposed in 2013 by billionaire entrepreneur Elon Musk, CEO of Tesla Motors and SpaceX, the Hyperloop would transport passengers in floating pods inside low-pressure tubes at speeds of more than 750 mph (1,200 km/h).
Now, the company Hyperloop Transportation Technologies Inc. (which is not affiliated with Musk or Tesla) has inked a deal with landowners in central California to build the world’s first Hyperloop test track, according to market research firm Navigant Research. The 5-mile (8 km) test track will be built along California’s Interstate 5.
Separately, Musk has said he plans to build his own 5-mile test track, likely in Texas, for companies and students to test out potential Hyperloop designs.
How Hyperloop will work as per Musk
Musk laid out his plans for the Hyperloop in a paper published on the SpaceX website. He has described the superspeedy mode of transport as a “cross between a Concorde, a rail gun and an air-hockey table.”
The idea is, passenger pods will travel inside tubes under a partial vacuum, and will be accelerated to blistering speeds using magnets. A set of fans attached to the pods will allow the train to rest on a cushion of air. The system would be powered by solar panels along the length of the tube.
The world’s fastest magnetically levitated (maglev) train travels at about 310 mph (500 km/h). Maglev trains work by using magnets to produce both lift and propulsion. By contrast, the hyperloop would only use magnets for propulsion, relying on compressed air for lift. Maglev trains are in operation in Shanghai and Tokyo, and South Korea plans to open one in June.
Hyperloop pods could theoretically travel very fast, because they wouldn’t have to overcome friction between the wheels and track that a typical train uses, or the air resistance that conventional vehicles experience at high speeds.
“You can go a couple of hundred miles an hour with a wheel, as the French and Germans and Japanese have proven,” said Marc Thompson, an engineering consultant at Thompson Consulting Inc. in Boston, who has worked on maglev systems. But, “as you go faster, the drag force on the train becomes a very high energy cost.”
The design Musk proposed would travel at speeds of up to about 760 mph (1,220 km/h), but the test project, which aims to break ground in early 2016, would be tested at 200 mph (322 km/h) to prove it works and is safe, Navigant reported.
At that speed, the air drag is still possible to overcome, but beyond that, the power needed to exceed the drag increases as the speed cubed, said James Powell, a retired physicist and co-inventor of the superconducting maglev concept.
This can be possibly put into existence in duration of 5 to 6 more years, also a rumor that it can be opened for general public in 2021.
