That each person of a planet could make by request to itself personal weather, not do without good transparent domes. The space mirror it is certainly good, but I will make it for other purposes. in 2005 trained with a dome 120х80 meters. Has tried in different variants. It was pleasant. From easy movements of a tiny dome 16х10 meters through an easy step 120х80 meters to warm-up 500х500 meters and to begin at last training from 1000х1000 meters to 10 000х10000 meters and further without reducing rate, with installation of domes on other planets.
