Doubles TurboPHASE output for 30 minutes or more Each GSX package adds zero to 12 lb/sec (high speed regula?on) Makes the en?re TurboPHASE system look like a 50 MW baqery ( 25 MW from TurboPHASE and 25 MW from GSX) GSX charges in 20 hours, 5500 psi air tanks, and consumes 500kw/hr. GSX tanks sized for 30 minutes discharge at full flow rate, can be slower/longer.
