Abstract: The solar power plant contains the radiation concentrator fitted with a drive, the system of Sun tracking with a control unit, and a fixedly attached radiation detector, and the drive is made with a possibility of ensuring a straight-line reciprocating movement of the concentrator, and the concentrator is mirror-based with a cylindrical surface having a guide whose current radius value features a deviation from the average value corresponding to the circumradius of the circular cylinder guide by no more than ±10%, and the radiation detector—photoelectric converter, is located in the focal plane.

Abstract: Thermal destruction of waste includes forming a bath of a melted slag, heating the waste and introducing the waste onto a surface of the bath, passing produced off-gasses through the melted slag, discharging the off-gasses, releasing produced metal and slag from the bath, forming in the closed volume a plasma hose over the surface of the bath by a coaxial electric arc plasma torch by two tubular electrodes located one inside the other, and introducing the waste through an interior of the inner electrode and then through the plasma hose.
