Achieving optical efficiencies substantially higher than that requires departing from the traditional mono-tower design. Although multi-tower systems were identified long time ago as candidates to achieve high annual optical efficiencies, so far no multi-tower concept has emerged as a clear alternative to the mono-tower system. In this article, we introduce a variant of the multi-tower concept that combines the modularity and high land coverage of linear focusing technologies with the low thermal losses and high operating temperatures of solar tower technology, and overall represents a disruptive departure from the traditional mono-tower design.This research was performed as part of the Australian Solar Thermal Research Initiative (ASTRI), a project supported by the Australian Government, through the Australian Renewable Energy Agency (ARENA).application/pdfen-AU© 2018 authors201810.1063/1.50671652022-10-02
