Pentadyne Selected as ``Most Promising Company'' at Energy Venture Fair V

CHATSWORTH, Calif.--(BUSINESS WIRE)--Nov. 22, 2004--Pentadyne Power Corporation, a manufacturer of advanced flywheel power systems, was recently named the most promising company for the second year in a row by approximately 500 attendees of Energy Venture Fair V, the 5th annual capital funding and energy investor conference.

Energy Venture Fair V, held in San Jose on November 10th and 11th, brought together 75 handpicked energy technology product and service companies seeking capital funding with venture capitalists, corporate investors and strategic investors looking for investment opportunities, strategic alliances and access to emerging energy technologies.

"We are very pleased to be named as the 'Most Promising Company' again this year. Such an honor is recognition for the great strides Pentadyne has made over the past twelve months, including the successful completion of our Beta field trials and the addition of Emerson Network Power/Liebert as our marquee distributor for uninterruptible power supply (UPS) applications," said Paul Craig, CEO of Pentadyne.

Last month, at the Emerson Network Power Incredible Universe trade show, Emerson introduced the Liebert FS Advanced Flywheel Energy Storage System, a kinetic energy system based on the Pentadyne flywheel that augments or replaces lead-acid batteries in Liebert UPS products. The Liebert FS is designed to support larger Liebert UPS systems, including the Liebert Npower, Series 300 and Series 610 models. It provides backup power to ride through short interruptions and enables transition to a backup generator. A single flywheel can be sized to support UPS systems up to 150 kVA. Multiple flywheel systems can operate in parallel to support larger systems.
