In the automotive sector, the most global and interesting changes are taking place in the electric vehicle industry. The speed of development of this transport is simply impressive: until recently, from a useless, fashion toy, they are slowly becoming an integral part of our lives. Alas, this type of transport has many disadvantages that prevent its use everywhere. At this point in time, they are widely used in regions where there are favorable conditions for their operation. These conditions include not only natural factors, such as a warm climate, but also the development of the region. The development of an enabling environment will play a key role in their ubiquity. In such regions, with a large number of charging stations, benefits and services, the electric car is already imposing worthy competition on classic modes of transport. Therefore, scientists from all over the world are struggling to solve issues related to the performance and recycling of waste when disposing batteries. With the solution of such problems, the purchase of such a car will not only be environmentally sound, but also economically justified, to the point that this type of transport will be able, in the near future, to replace the cars with internal combustion engines that are familiar to us.

One of the methods implemented in alternative energy is the transition from gravitational energy to thermal energy and then to electricity. This transformation is carried out in a gravitational power plant. The physics of the process in one of these converters is considered. It is shown that the work of gravity stations resembles the processes of the water cycle in nature. To date, many options for implementing this idea have been proposed. Moreover, author's certificates on the subject of “gravity dam” appeared in the USSR back in the 1970s. Currently, there are patent solutions, both for entire power plants, and for individual units and even engines.
