Reveo's Subsidiary eVionyx wins 3 SBIR contracts from Department of Defense.

HAWTHORNE, NY (June 30, 2004) - Reveo's subsidiary, eVionyx, has been awarded 3 separate SBIR contracts from the Department of Defense for work on various energy related projects. eVionyx has long been recognized as an innovator in developing new energy solutions, and these contracts re-affirm its technological capabilities in a wide variety of energy related subjects.

The first contract, entitled "Hybridized Magnesium Air Fuel Cell With Ni-Zn Battery or Electrochemical Capacitor as the Ideal Energy Source for USV Sensor Payloads" builds upon the successes of eVionyx in developing its metal-air fuel cell systems. Relying on proprietary components developed by eVionyx, the magnesium-air fuel cell can provide extraordinary amounts of energy. eVionyx also has deep experience in hybridized systems, as demonstrated in its Guiness World Record MeVictory event, in which the world's first all-electric hybridized powertrain powered a Honda Insight to a record breaking 525 km.

The second contract, entitled "Portable, Lightweight, Amalgamated Thin-film Photovoltaic/Lithium-ion Battery Combination" relies on a thin film depostion technique used extensively at Reveo laboratories to fashion an ultra compact, thin film system. This technique allows for the creation of nanostructures, which have been shown to improve various electrochemical properties. Once again, this contract calls for a hybridized system, an expertise in which eVionyx is uniquely qualified for.

The third contract, entitled "Novel Oxygen Pump for High Altitude Air Breathing Engines" is a brand new technology that is an outgrowth of eVionyx and Reveo's long held efforts in developing an oxyen compressor. eVionyx and Reveo scientitsts have worked hard on the creation of new materials and membranes that will enable this technology to become a reality. eVionyx Chief Technology Officer, Dr. Lin-Feng Li, is the inventor and is excited about what this could one day mean for all combustion based energy sources.

These three contracts, albeit in three very different directions, are all crucial to the future success of eVionyx and its efforts at developing new energy solutions to benefit humanity. They are the culmination of years of research at both eVionyx and Reveo. Reveo continues to be an important contributor to eVionyx, transferring its latest developments and know-how, so that eVionyx can continue to push the technological envelope. Reveo looks forward to the many successes that eVionyx is sure to bring forward over the next few years as a result of these contracts.
