Humans are no stranger to taking on technological challenges. Hollywood movies have imagined a future of hoverboards(悬浮滑板) and flying cars. What's new and popular today? Let's take a look.
The Robotaxi
In a Robotaxi, no one drives, it drives by itself. You just tell where and it goes. It's like a magic ride, but a car! It watches the road with computers and cameras. They can reduce the number of cars on city streets by 60% and road accidents by 90%.
The Flying Cars
Flying cars include passenger drones(无人机) and helicopter hybrids(混动). Because the sky will never be as busy as the roads are. It may take you 30 minutes instead of 2 hours to go to a friend's house. Besides, it only costs around 60 dollars, and you get to fly. Isn't it cool?
The High-speed Trains
China is leading the world in high-speed trains. The latest type of trains can run at the top speed of 450 kilometers per hour. It has set a world record for the fastest train speed. The high-speed trains make the travel safer, greener and more comfortable. In recent years, these trains have been sold to 23 countries.
The Starship Rockets
SpaceX company's new rocket, Starship has completed its first flight. SpaceX engineers take this task as a great success. After a rocket finishes its job, it usually falls and breaks. But the Starship rockets don't break. By reusing the most expensive part of the rocket, it reduces the cost a lot.
