Publication number: 20130049473Abstract: An Uninterruptible Power Supply (UPS) for providing power to a computer system. The UPS converts kinetic energy of cooling fluid already being pumped through the computer system to operate a reaction turbine. The turbine drives a flywheel, which in turn can drive a generator in the case of a power failure. A gravity feed may continue to supply cooling fluid to the system, at least for a time, after the power is lost. The turbine can continue to store this energy in the flywheel after power failure thereby extending the ride-through time available.Type: ApplicationFiled: August 23, 2011Publication date: February 28, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Brad L.
