Table 9: Metal production rates by solar thermal, solar + E-beam thermal, and E-beam spectral, based on current assumptions, 5-m dish and 10-m Cassegrain dish.

Metal Production Rate

 

5-meter dish solar thermal (ST): 21 KW (M = 84 grams for every 69 seconds)

10-meter dish solar thermal (ST): 85 KW (M = 168 grams for every 34 seconds)
