Virgin Hyperloop completes world's first human test
How many hurdles stand in the way of hyperloops becoming a commercial reality?
- Hyperloops are a new type of transportation technology that involves vacuum tubes and passenger pods traveling at ultra-fast speeds.
- Although no commercial hyperloops exist yet, a handful of companies around the world are building test tracks, some in partnerships with national governments.
- Hyperloops could prove to be a faster and more environmentally sustainable form of transportation than flying and high-speed rail, though many obstacles remain.
Virgin Hyperloop has successfully completed the world's first passenger test of hyperloop technology, a new form of high-speed transportation.
The test was conducted Sunday in a desert outside of Las Vegas, where the company built a 500-meter vacuum tube as a test track. Inside the tube, a pod carrying two passengers used electric propulsion and electromagnetic levitation to whisk above the track, reaching 107 mph in about six seconds before coming to a stop.
Virgin's test was designed to prove the safety of hyperloop technology for humans. The company, founded in 2014, hopes to build long-distance hyperloops that travel up to 600 mph, meaning a trip from New York City to Washington, D.C. would take about 30 minutes.
"With today's successful test, we have shown that this spirit of innovation will in fact change the way people everywhere live, work, and travel in the years to come," said Richard Branson, founder of the Virgin Group, in a statement.
It's a big milestone for the technology, which Elon Musk first proposed in 2012. Still, Virgin and other hyperloop companies have many hurdles to overcome before hyperloops become a viable form of transportation.
In addition to proving hyperloops are safe for humans at faster speeds, two major obstacles include:
- Cost: Building and maintaining miles of hyperloop tubes would be incredibly expensive, with leaked documents from 2016 suggesting that each mile of track could cost between $84 million and $121 million. It's unclear whether hyperloops could sell enough tickets at high enough prices to turn a profit, while competing with airlines and railways.
- Land: Due to the high speeds, hyperloop tracks would need to be constructed in near-straight lines. Turns would have to be wide: A Virgin Hyperloop engineer told the New York Times that a hyperloop pod would need about six miles of track to complete a 90-degree turn at 600 mph. It's unclear how or whether Virgin (or other hyperloop companies) would be able to buy or gain rights for all the necessary land to build the tracks.

Hyperloop companies, which would be overseen by the Federal Railroad Administration, would also have to sort out issues related to headway, maintaining a vacuum in the tubes, emergency exits, government regulations, passenger capacity and the simple possibility that people might not want to shoot through a vacuum tube at 600 mph.
(On that note: It's unlikely that hyperloops would reach average speeds of 600 mph because the pods would need to accelerate and decelerate at slower speeds for safety and comfort reasons.)
But hyperloop technology is moving forward. In July, the U.S. government published a policy document intended to serve as a regulatory "roadmap" for hyperloop companies seeking to test their technology in the country. Virgin recently announced plans to build a $500 million "certification center" in West Virginia, where the company will test future versions of its hyperloops, aiming to get government approval.
Virgin plans to build its first operational hyperloop in India, whose government has been in talks with the company since 2017. While still in the planning stages, the company hopes to have a commercial hyperloop up and running in India by around 2030.
Underground tunnel built by the Boring Company
Virgin isn't alone in the hyperloop space. For example, there's Los Angeles-based Hyperloop Transportation Technologies, which is working on test projects in the United Arab Emirates, France, and Germany, where the company aims to move cargo through hyperloops. The company said it hopes to open its first commercial operation by 2022.
Hardt Global Mobility, a Dutch hyperloop startup, hopes to build a 10,000-kilometer network of hyperloops throughout Europe. Meanwhile, Elon Musk's Boring Company is building underground tunnels designed for cars traveling short distances. But the company says its tunnels "are designed and built in preparation for their eventual transition to Hyperloop."Some critics of hyperloop technology say it's a "utopian vision" that's unlikely to pan out, while others note that hyperloops would essentially be maglev trains, but more expensive and faster (because the vacuum tube reduces drag). But if successful, hyperloops could not only decrease travel times, but also become a more sustainable form of transportation, potentially magnitudes more efficient than high-speed rail and flying.

What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.
- Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
- That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
- We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
The inherent worth of all human beings<p>Human dignity is the inherent worth of each individual human being. Recognizing human dignity means respecting human beings' special value—value that sets us apart from other animals; value that is intrinsic and cannot be lost.</p> <p>Liberalism—the broad political philosophy that organizes society around liberty, justice, and equality—is rooted in the idea of human dignity. Liberalism assumes each of our lives, plans, and preferences have some unimpeachable value, not because of any objective evaluation or contribution to a greater good, but simply because they belong to a human being. We are human, and therefore deserving of a baseline level of respect. </p> <p>Because so many of us take human dignity for granted—just a fact of our humanness—it's usually only when someone's dignity is ignored or violated that we feel compelled to talk about it. </p> <p>But human dignity means more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose—a freedom that can be hampered by restrictive social institutions or the tyranny of the majority. The liberal ideal of the good society is not just peaceful but also pluralistic: It is a society in which we respect others' right to think and live differently than we do.</p>

The future of dignity<p>Around the world, people are still working toward the full and equal recognition of human dignity. Every year, new speeches and writings help us understand what dignity is—not only what it looks like when dignity is violated but also what it looks like when dignity is honored. In his posthumous essay, Congressman Lewis wrote, "When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war."</p> <p>The more we talk about human dignity, the better we understand it. And the sooner we can make progress toward a shared vision of peace, freedom, and mutual respect for all. </p>
Scientists find that bursts of gamma rays may exceed the speed of light and cause time-reversibility.
- Astrophysicists propose that gamma-ray bursts may exceed the speed of light.
- The superluminal jets may also be responsible for time-reversibility.
- The finding doesn't go against Einstein's theory because this effect happens in the jet medium not a vacuum.

Researchers dramatically improve the accuracy of a number that connects fundamental forces.
- A team of physicists carried out experiments to determine the precise value of the fine-structure constant.
- This pure number describes the strength of the electromagnetic forces between elementary particles.
- The scientists improved the accuracy of this measurement by 2.5 times.
The process for measuring the fine-structure constant involved a beam of light from a laser that caused an atom to recoil. The red and blue colors indicate the light wave's peaks and troughs, respectively.
Scientists at Washington University are patenting a new electrolyzer designed for frigid Martian water.
- Mars explorers will need more oxygen and hydrogen than they can carry to the Red Planet.
- Martian water may be able to provide these elements, but it is extremely salty water.
- The new method can pull oxygen and hydrogen for breathing and fuel from Martian brine.
