Though a few notable projects have tested gas turbines on small solar towers with mirror fields, there have only been two truly Dish-Brayton demonstrations. The first, in 1984, was led by Sanders Associates, using a microturbine designed by Allied Signal (Torrance, CA), a Lajet 460 dish, and a Sanders receiver. On August 30, 2011, Brayton and SST successfully tested the world’s second dish-Brayton. This system employed the SST 320 Sq. meter dish, with a purpose-built gas turbine and receiver designed and built by Brayton Energy. The Dish-Brayton is believed by many engineers to offer substantially better reliability and a long (60,000 hour) maintenance-free life as compared to the Dish-Stirling.
