Technologies that will dominate the world in 2100 (Part 2)

In 2100, we can 'travel the globe in a very short time compared to the present . The fact that people go to work in other countries on a rocket, connecting Americans with muscles. Global Assembly is completely feasible.

In the next 100 years, what kind of machines will change the world? How will they make our lives better, cleaner, safer, more productive and more enjoyable? Continue to learn about 2100 machinery technology from Popular Mechanics, the famous science magazine with over 100 years of American history.

Faster transport system, higher efficiency

Experts are optimistic that, by 2100, many infrastructure issues will be repaired with support from many large and small machines.

First , there will be very small machines, like thousands, of millions of tiny machines working together as a troop to repair bridges quickly, accurately, or build emergency infrastructure after floods. great. That is the future potential of nanotechnology.

Secondly , in 2010, outdated transport systems will now be replaced by completely new high-speed rail systems. There are systems in the first phase of construction, typically California high-speed rail (HSR) systems from Los Angeles to San Francisco expected to be completed in 2029.

At the end of the 21st century, throughout the United States will be high-speed railways and pipelines that overlap, running through the long-standing infrastructure of private investment. As expected, by 2100, you can travel from Washington DC to New York in less than 30 minutes (the actual time for the same route by train is about 4 hours, while the plane is 1 hour, Including the subway time to the train station, according to Travel Bank).

Followed by flying cars , the future air transport revolution. Currently, semi-automatic systems are available in commercial aviation. By the 22nd century, the unmanned mode would continue their natural evolution, when the aircraft were carried out remotely or completely automatically. 'Making auto planes is actually much easier than making automatic cars,' said Stephen Pope, editor of Flying magazine.

In 2100, we can 'travel the globe in a very short time compared to the present . The fact that people go to work in other countries on a rocket, connecting Americans with muscles. The global society is completely feasible. " This is the prediction of the current US female minister of transport, Elaine Chao.

In addition to the minister, SpaceX's Elon Musk also shared her dream of traveling through the city when she announced a plan to build a system to take you anywhere in the world in less than an hour.

New technology addresses the essential needs of people

In addition to the future technologies that help solve macro issues, fully exploiting the ocean resources is also the most widespread work. A major problem now is clean drinking water, because although the Earth's surface has 71% water, 90% of them cannot drink because it is salty or polluted. Professor Alvarez-Cohen from UC Berkeley (USA) said that in the next century, we will develop the most efficient water purifier, ending the global water crisis.

After an important need for water, another human need will be repaired, it is housing. According to most of the forecasts, the earth's house will have 11 billion people in 2100, making people almost no space to live.

But there is still a place where a lot of space is under our feet. "Goose" billionaire Elon Musk, CEO of giants Tesla and SpaceX, began using some machines to dig tunnels under big cities. Popular Mechanics devices called 'boring' will help build underground infrastructure relatively quickly and cost-effectively.

Underground construction will address the current infrastructure crisis and open up more space for people in the future, which is CEO of Zach Schafer - CEO Week. The reason is because it is reliable and protected from more factors. People can leave life on the ground, no noise and no separation by overpasses or highways. '

Space: The new home of humanity

By 2100, working and living in space is no longer limited to some privileged people but it is normal. Popular Mechanics introduced a number of machines for the need to "go" between Earth and space.

First of all, that space elevator. This idea of ​​daydreaming from the late 19th century is quite simple but conceptually difficult in reality.

It's a car tied into a very strong straight line made of magnets or powerful robots so that cars can climb thousands of kilometers into space. Elevators will make space travel easier, cheaper and more frequent.

Only projects that are starting to start up, the main difficulty of elevators is finding a chain material that ensures all three standards: strong, light, and cheap. Experts hope this problem will be solved by 2100 to create opportunities for more people to fly away from Earth.'Reduce the cost of accessing space, which will open the opportunity to establish an independent solar economy from space hotels, missions to the moon, Mars and distant more, ' said Kelvin Long, president of the IIS Star Research Institute.

Space elevators are not only used for space travel but also for long distance travel every day. By 2100, there will be villages self-sufficient on the moon, and more ambitious Mars. Although it may not be much, only a few hundred people, these people will need machines to exploit the available resources and fix them themselves. And to travel from one asteroid to the next, we will leap on fully built spacecraft in space.

In addition, advances in propulsion technology will help us explore deeper galaxies like never before. Strongly oriented nuclear and laser technology will contribute significantly to reducing travel time to the furthest points of the Milky Way. These advances will ' improve the performance of trips to Mars . reduce the risk of astronauts' health, reduce radiation exposure, consumables, and countless material needed for the journey'. , according to NASA's Transitional Authorization Act signed by President Donald Trump last year.

This will be the first turning point in 'America changing the space goal of successful discovery of human solar systems in 2010,' according to NASA's Propulsion Engineer, Ron Litchford. Ron explained that the combination of miniaturized nuclear power systems and huge laser arrays using high energy throughout the solar system will help us enter the universe many times faster.

He estimates that in the next century, maybe we will travel 10-20% faster than the speed of light, three times more than the Parker Solar Probe satellite launched last year. Further, new propulsion technologies can help us establish Jupiter's moon human colony.

The final idea is the unmanned aerial small space satellites, 22nd-century descendants of Voyager, New Horizons. They will travel further into the universe, extending far into Alpha Centauri (the most solar system near the sun, 4.37 billion light-years from the sun).

New-generation satellites may be smaller than current credit cards, run on nuclear batteries the size of a 25-cent US dollar (25 mm diameter and 2mm thick), use the camera only marginally better than a camera The iPhone is now available, but it can send high-resolution photos of 'a planetary alien planet , ' according to chief executive IIS, Andreas Hein.
