They are not shooting a scene for a fantastic movie here. The magnificent construction you see is a solar surface located in Uzbekistan.
There are only two such furnaces in the world till now. One of them is situated in France.
A solar furnace is a complex optical and mechanical construction supplied with automatically controlled systems.
The furnace makes use of a large parabolic reflector concentrating the sun into an area the size of the common cooking pot. The reflector is discrete; 63 individual flat mirrors track the sun in unison and redirect the solar thermal energy towards the crucible.
'By will of the Communist party and by wish of people the complex SUN will be erected here', May, 1981. Academician S.A. Asimov made a large contribution into development of the complex, the highest point of which is located 1100 m above the sea level.
