On Wednesday, August 09, Seattle-based American Flywheel Systems Inc. (AFS) announced that it has acquired 58 percent of Livermore-based Trinity Flywheel Power for an undisclosed price and has introduced new capital and management into the company. The company also reported that Trinity is now taking orders for up to 225 kVA (191 kW) super-fast recharge UPS and ride-through systems, with deliveries commencing in 2001. The company believes these are the first flywheel systems that can handle not only initial power anomalies from the utility grid, but systems also capable of protecting the digital economy from rapid successions of both minor and major sags and spikes. Trinity said that this capability is a result of its bore-loaded, composite flywheel rotor and ironless motor generator, which, unlike heavier and slower flywheel systems, can discharge and recharge completely in 10 to 20 seconds. AFS and Trinity President and Chief Operating Officer Joel Levinthal explained: “Our strategy is to occupy the middle ground between sub-low-speed steel flywheels — now around 8,000 rpm — and experimental super-high-speed carbon fiber flywheels — targeted for 90,000- to 100,000-rpm operation. “We operate our composite flywheel at 40,000 rpm, which means we don’t have to push the envelope. Our rotor has also undergone extensive independent safety tests conducted by Test Devices Inc. for the U.S. government that show it operates within a generous and reliable safety margin.”
