Figure Legend:
Left: ganged normal vectors: ends of parallel orange vectors to the sun move on spherical shapes. The blue normal vectors of the mirror planes are fixed to the green vectors to the receiver and to the ends of the orange sun vectors and can be connected by a horizontal rod (blue) to realize ganged normal vectors (compare Ref. [29]); right: ganged heliostats according to Ref. [30] (not tested yet).
