In the project DISTAL II, three dish/Stirling-systems were built on the Spanish-German solar test centre Plataforma Solar de Almería. The concentrators were constructed using metal membrane technology and an innovative laser welding technique. The Stirling motor was refined and a completely new automatic drive and control system was employed. The units were used for demonstration and testing purposes and operated in co-operation with the DLR (German Aerospace Centre) for more than 10,000 accumulated hours up until
2003.
