When will we receive Hyperloop – the transport of the future

Originally developed by SpaceX CEO Elon Musk, Hyperloop is a new form of ground transportation that will allow passengers to travel between locations at speeds in excess of 1,100 km per hour.

If you think about it, the futuristic concept of Hyperloop – if it is erected – will produce a real transport revolution. Just imagine: passengers board capsules that move them to their destination faster than airplanes through hermetic tubes. Hyperloop runs on an electric motor and magnetic levitation. However, even though it looks like science fiction, Hyperloop will soon become a reality.

What is Hyperloop?

The idea of ​​Hyperloop came to the mind of the founder of SpaceX and Tesla, Elon Mask, in 2012. However, the entrepreneur set out his vision of an ultra-fast transport system that will move capsules with passengers through steel pipes many years ago. We don’t know if Futurama’s animated series has anything to do with this idea, but it’s very similar to that. Let us remind you, according to the plot, in 3000, people just went into a pipe, which carried them to their destination at great speed.

This is how the Hyperloop passenger compartment might look like

In simple words, the Hyperloop is a train in a pipe. The fact is that air can be pumped out of the pipe and its resistance reduced. The lower the resistance, the higher the speed can be developed. But the path from the idea to its implementation is not easy. So, with an estimated price of $ 6 billion, the Hyperloop concept will never be realized. But regardless of the cost and complexity of building an almost supersonic ground transportation system, according to the head of Tesla, Hyperloop is a cross between an airplane and a train.

It looks like the hyperloop capsule is built by Virgin Hyperloop One

Indeed, there is nothing fundamentally new in the idea of ​​a hyper loop, and all technologies have been tested for a long time, so all that is left is to simply assemble them together. It is noteworthy that the concept of futuristic hyper Loop will be open source. Let us remind you that open source code is a computer program code that is open to all users and allows you to learn during use.

Real Hyperloop Speed

According to the idea – depending on the landscape – Hyperloop speed should reach from 480 to 1220 km / h. The speed of the existing Hyperloop capsules – Virgin Hyperloop One – reaches 387 km per hour. But the record belongs to the German company TUM Hyperloop, which in 2018 managed to disperse the capsule to 457 kilometers per hour.

Who is working on creating the Hyperloop?

Earlier, Musk called on the world community and companies to develop the necessary technology of hyperloop, without the participation of the entrepreneur himself. This led to the formation of many startups and student teams that are working on the development of Hyperloop and translating it into reality. So, recently it became known about considering proposals for the construction of Hyperloop between Paris and Amsterdam, which could transport passengers from one point to another in less than 90 minutes.

But, startup Virgin Hyperloop One, founded by Richard Branson, already in 2017, built a full-size capsule on test tracks in Nevada. Reportedly, the capsule managed to accelerate to 387 km per hour. Recall that the company seeks to achieve a maximum speed of 1220 km / h. At the same time, Virgin Hyperloop deviates slightly from the original plan of Elon Mask, since it combines two main principles:

Firstly, magnetic levitation is a technology that is already used in monorails for lifting passenger capsules and moving them. For magnetic levitation, two sets of magnets are used – one pair lifts the capsules from the paths, and the second moves them at high speed with reduced friction.

Secondly, a vacuum sealed medium with low pressure removes most of the air from the pipes and has no contact with the ground. As a result, the capsules encounter little resistance when moving. It is noteworthy that the air pressure inside the pipe is equivalent to flying at an altitude of 61 km above sea level.

The construction of transport of the future is in full swing

Where will Hyperloop be built?

Virgin Hyperloop One launched the global task of finding the best routes for the new transport system. Out of more than 2,600 proposals for locating hyperloop stations from around the world, the list has been reduced to 35 potential locations. So, with 10 winners around the world, Hyperloop can work in partnership with the government of each of the locations.

Is Hyperloop Technology Safe?

Virgin hyperloop One explains that they have to build thick steel pipes that are extremely difficult to pierce or break. In addition, the pipes are designed to withstand changes in pressure and air leakage, while maintaining their structural integrity. It is also possible to cut off parts of the route and re-pressurize areas where emergency situations occur, and all capsules are expected to be equipped with emergency exits

At the same time, the trip cost in a hyper loop will be lower than a plane ticket, because there are no such large infrastructure costs as in the case of airports, and the operation of the route itself is also inexpensive. One way or another, we should all be preparing for the revolution in passenger and transportation in the next decade. The future is very near.

A picture from the Internet killed Samsung smartphones

The image from the network led to the breakdown of Samsung smartphones. The image was shared by an insider of Ice Universe on his Twitter.

“Never set this picture as wallpaper, especially on Samsung smartphones,” said the blogger, emphasizing that the image from the Internet can break the device. Despite the warning, Ice Universe made a link to the landscape with an image of a flooded island in the setting sun “for enthusiasts.”

Users of Samsung smartphones in the comments confirmed that the mysterious image can really “kill” the device. In particular, after setting the picture as wallpaper, the phone may reboot or turn off, which is fraught with data loss. The comments explained that the cause of the failure could be an incorrect color profile of the file that the system cannot process.

The author later clarified that Samsung was aware of the problem and had already released a special update. The blogger also published a landscape breaking smartphones on the Chinese Weibo service, noting that when loading the social network automatically changes the color profile of the picture.

Samsung device owners who set the image as wallpaper were advised to remove it through safe mode. If the device does not boot in the selected mode, then a clean installation of Android should be performed on the smartphone.

The first ever SpaceX rocket launch with crew will be shown online

May 27, 2020 may go down in the history of astronautics as the day when people first reached the orbit of the Earth on aircraft, fully developed by a private company and owned by it. Previously, without the participation of state organizations, people were only launched into suborbital flights.

The SpaceX-created by Elon Mask, a partially reusable heavy Falcon 9 booster rocket and the Crew Dragon passenger ship, should launch today from the launch site at Cape Canaveral in Florida. The task – to deliver to the International Space Station two NASA astronauts, Doug Hurley and Bob Benken.

Elon Musk tweeted a photograph of the launch site this early morning:

The live broadcast of the launch, which is tentatively scheduled for 16:33 by the east coast of the United States, can be viewed on the official NASA YouTube channel:

As confirmed by CBS News in the press service of the White House, President Donald Trump, despite the ongoing epidemic of COVID-19, decided to personally attend the historic launch and will arrive at Cape Canaveral. Last week, Trump said he was “thinking” about visiting the cosmodrome and added that he would gladly send journalists on a rocket into space to get rid of them for a while. 

True, the start may still be postponed due to bad weather. If the conditions prove to be unfavorable, it will be postponed to the 30th or 31st of May.

The first SpaceX passenger ship, the Crew Dragon, is an evolution of the Dragon transporter, which has recently made several deliveries to the ISS. In total, it can take on board up to 7 crew members, but this time only two will fly, and the rest of the space will be taken by cargo.

The interior of the ship reminds of sci-fi films, and touch screens are used for control, as in electric cars of another company Ilona Mask, Tesla.

The last time the United States National Aeronautics and Space Administration (NASA) launched its astronauts from the United States on an American spacecraft in July 2011. After the crash of the “space shuttle” Columbia in 2003, it was decided to gradually phase out the shuttle program and focus on developing a new ship that would also be suitable for traveling to the moon.

The first manned space flight, organized by a private company, took place back in 2004 – the SpaceShipOne rocket plane with pilot Brian Bonnie on board, reached a height of 100 km above the surface in a suborbital flight and successfully returned to Earth. For comparison, the altitude of the orbit of the ISS, where the Crew Dragon astronauts go, exceeds 400 km. 

SpaceShipOne was developed and launched by Mojave Aerospace Ventures, a joint venture between Microsoft co-founder Paul Allen and engineer Burt Rutan of Scaled Composites.

Scientists have created a robotic eye that is completely similar to human

The developers plan to make it completely autonomous due to power from sunlight.

Scientists have created an artificial eye, the device of which almost completely copies the structure of the human organ of vision. Its diameter is about two centimeters, it has a retina made of nanowires and a lens for focusing light instead of the lens. The article describing the development was published by the scientific journal Nature.

We can see due to the fact that the light that enters the eyes passes inside them through the lens system and enters the photoreceptors in the retina. They convert particles of light into signals that are transmitted to the brain. Scientists have long been trying to reconstruct this complex system to create robots or in order to try to restore lost vision to people.

Another and relatively successful attempt to achieve this was made by scientists led by Zhiyong Fang of Hong Kong University of Science and Technology. The artificial eye that they created looks like a ball about two centimeters in diameter, filled with a fluid that conducts electric current. The eye of an adult is about the same size, inside it is also filled with a jelly-like liquid.

The device can see thanks to an artificial retina made of photosensitive nanowires. They are made on the basis of perovskite – a hybrid material, which due to its unique structure is now widely used in solar panels. Nanowires react to light and transmit a signal about it further like the photoreceptors of the human eye.

To test whether this eye can see, scientists projected images of several letters onto it. The device successfully recognized the letters I, E, and Y. However, while it creates an image of rather poor quality – about 100 pixels, compared with 120-140 megapixels of the human eye.

For operation, the device needs an external power source. However, scientists plan to make the artificial eye self-contained so that the device works like a small solar cell.

Among other plans of scientists – to check whether it is possible to subculture these nanowires to the human optical nerve. In addition, the developers hope to increase the quality of the picture to the level of the human eye and even surpass it by an order of magnitude.
