EXPO in Kazakhstan started on June 10 and will last until September 10. The theme of this year's exhibition is devoted to the effective use of the energy of the future. Researchers unanimously affirm that society must move to search for alternative energy. Scientists talk about the extraction of energy from underwater ocean currents, waves and ... cosmic dust. And all this with the help of modern technologies, which, for 1 minute, allow to generate from the same solar power station (with an area of 10 to 10 meters) the same amount of electricity as a modern nuclear power plant.
