Chatsworth , Calif. - June 4, 2007 - Pentadyne Power Corporation ( www.pentadyne.com ), the world's leading commercial manufacturer of clean energy storage systems using advanced composite flywheel technology, today announced that Buildings magazine ( www.buildings.com ) has selected the company's VSS + DC system as a 2007 Editors' Choice Top Product Pick .

Buildings is a 100-year old publication read by more than 72,000 commercial building owners and professional facilities managers. Its readers are responsible for nearly 4.5 million commercial and institutional buildings nationwide.

Throughout the year, Buildings' editorial board maintains a database of innovative and efficient products to help its readers in their responsibilities for building development, construction, modernization, management and operations. The editors reviewed thousands of products and picked the top 100 they felt were worthy of recognition above all others.

Criteria for selection includes aesthetics, ease of use, durability/life-cycle, efficiency, universal appeal and sustainable/green aspects, among others.

"As the nation's leading publication for building management professionals, Buildings magazine particularly focuses on energy efficient and environmentally beneficial products," said Pentadyne CEO Mark McGough. "Our flywheel systems use only 1/10 th the power needed by competing products. Over the course of their 20-year design life, each Pentadyne system deployed instead of UPS lead-acid batteries prevents battery greenhouse gas emissions and the dumping of more than 15,000 pounds of lead and hundreds of gallons of sulfuric acid."

The list of products will be published in the magazine's June 2007 issue due out tomorrow.

"We are pleased to include the Pentadyne VSS + DC system as a Top Product Pick as a solution to improve the energy efficiency and reliability of continuous mission-critical IT and process operations at our readers' facilities," said Buildings Editorial Director Linda Monroe.

Exhibiting at upcoming trade shows
Pentadyne has a tabletop exhibit at the 7x24 Exchange Conference (www.7x24exchange.org/spring07 ) in Boca Raton , Florida , running today through Wednesday. At next week's Seattle AdaptiveXchange ( www.campbell-co.com/show ), a Pentadyne-made Liebert FS flywheel system will be on display June 11-13, and there will be presentations on the attributes of flywheel energy storage during the mornings of June 12 and 13.
