Cyclone Power Technologies has announced that the U.S. Patent and Trademark Office has issued a Notice of Patent Allowance on the centrifugal condenser of the Company's heat regenerative external combustion engine.

The patented centrifugal condenser, comprised in part of 40 stacked aluminum plates with over 60 sq.ft. of total surface space, serves to quickly and efficiently cool the steam exhausted from the engine's cylinders back into water.

The process is capable of lowering temperatures hundreds of degrees (F), thus allowing the Cyclone Engine to reuse its working fluid (de-ionized water) in a closed-loop process.

Additionally, the cooling air which becomes heated in the condensing process is regenerated by the Cyclone Engine and used to pre-heat combustion air in the engine's patented combustion chamber, thereby increasing thermal efficiencies.

The current patent on the Cyclone Engine is its fifth in the United States. The Company now has patents on each of the three major component systems of the engine - one on its combustion chamber, two on its mechanical operations (comprised of pistons, valves, bearings and other sub-components), and now one on the condensing system.

The Company has an overall patent on the total Cyclone Engine system in the United States and several other nations throughout the world.

"This new patent provides greater protection for our high-efficiency, clean air engine system, and added proof of the uniqueness of what we have built," stated Harry Schoell, Cyclone's CEO and inventor of the engine. "We feel that we have advanced modern steam technology for motive and small-scale power applications further than anyone else in the field."
