Progress does not stand still, adapt or disappear - there is a single law for everything in the world and cars are no exception. What will 21st century cars look like in crowded metropolitan areas, global warming and oil shortages?
An example for the role of the fuel of the future is hydrogen. Hydrogen is formed during the electrolysis of water; during combustion, it emits only water vapor, which does not pollute the world. But hydrogen also has disadvantages: firstly, it is expensive to create, and secondly, it explodes very easily on contact with oxygen. Most likely, the cars of the future will have an autopilot, very energy-intensive batteries, or autonomous energy sources such as thorium reactors.
Flying cars
The desire to create a flying machine that combines a car and an airplane arose among people after World War I. Ases did not want to part with the sky even in peacetime. Although the developments were carried out in all developed countries, the prototypes turned out to be cumbersome and difficult to operate. But in the future, vertical takeoff and landing vehicles will appear. The greatest success in this area was achieved by the American company Moller Skycar, presenting working models of the sky roadster, sedan and saucer.
Underwater cars
No matter how ridiculous it may sound, the growing population will force part of the population to leave to live under water. Japan, which has a small area and huge scientific potential, announced plans to build the first city under water - "Ocean Spiral". A diving vehicle has already been created, it is called the "Rinspeed sQuba". Although this novelty submerges only 10 meters and does not swim very quickly, further improvement of the promising project is obvious.
