ALM Completes 4th Month of Successful Subsystems Testing of its Revolutionary Microturbine.

Business Editors

WASHINGTON--(BUSINESS WIRE)--Sept. 19, 2001

ALM Turbine, Inc. ("ALM") announced today the completion of four months of intensive testing of its prototype microturbine subsystems at the test facilities of Alturdyne, Inc. in San Diego, CA and East-West Technology Testing Corporation of West Palm Beach, Fl.

The tests confirm that ALM has made a number of significant technological breakthroughs in microturbine technology, expected to result in a considerably cleaner and more efficient microturbine than those currently on the market.

Revolutionary combustion system - Over 150 successful starts (where no pilot fuel was required) have been performed, including several fast starts from ambient temperature. In addition to very high flame stability, testing has yielded / verified the following results:

-- NOx emissions of between 5ppm and 10ppm in an open cycle mode without a
catalytic device. Testing the engine in semi-closed mode should reduce NOx
emissions to below 5ppm utilizing exhaust gas recirculation ("EGR").

-- Combustion design proven to completely eliminate numerous fuel injectors,
pilot injectors, and related circumferential hot spots at the combustor exit.
This achievement facilitates lower NOx and eliminates expensive components
found in conventional gas turbines.

-- Combustor premixing device design verification. ALM has demonstrated stable
combustion with a 1:1 flow ratio between compressed air and exhaust gases,
proving that EGR can be used in gas turbines as it has been used in
reciprocating engines.

ALM's novel combustor was optimized with the assistance of Combustion Science & Engineering of Columbia, MD.

Novel Blade Cooling Technology - ALM tests have validated that its blade cooling technology possesses fewer losses than conventional blade cooling technologies despite significantly higher cooling flows.

Tests have also demonstrated a considerable reduction of the blade leading edge temperature at fairly high combustor exit temperatures, potentially increasing overall engine efficiency and eliminating the need for exotic and expensive blade materials.

Innovative Heat Exchanger Technology - ALM has successfully built and tested a proprietary recuperator and intercooler with demonstrated effectiveness of between 91-93%.

Revolutionary nozzle-less turbine design - ALM has effectively integrated its combustor and first stage turbine, successfully eliminating the first stage nozzle between the combustor and first stage turbine. This achievement increases overall engine efficiency and eliminates an expensive hot section component.

ALM Turbine, Inc is a microturbine technology development and commercialization company. ALM is currently developing a low emission, 37.5% efficient 300kW microturbine for stationary power applications and a 50kW unit for automotive applications.

Stationary generation applications include peak shaving, grid support, resource recovery, remote power, standby/back-up, UPS, CHP and base load. ALM currently has 16 patents and patent applications.
