GSPI Completes Algae to Biodiesel Winter Demo Testing

SAN DIEGO, California, Jan. 31 - /EWire/ -- Green Star Products, Inc. (OTC: GSPI) today announced that it has successfully completed Phase III for winter environmental testing of its hybrid algae production facility in Montana.

The GSPI hybrid algae production system is designed to provide a controlled algae growing environment at an affordable capital and maintenance cost, which has eluded engineers for more than three decades.

The GSPI system endured severe Montana winter conditions, which included many nighttime temperatures below -18º Celsius (0º Fahrenheit) and snowfalls of up to 355 mm (14 inches).

The 40,000 liter demonstration facility is located outdoors and had successfully completed Phase I and II of the project in mid-2007 (see details in press releases dated May 11 and July 9, 2007 at GreenStarUSA.com).

The algae demonstration project was not initially scheduled to continue into the winter months; however, the success of the first two phases of the project provided an opportunity to subject the algae hybrid system to severe Montana winter conditions to gather data never before attempted by any other research organization.

The successful testing and results of the cold weather program provided invaluable data that has increased the efficiency of the environmental control system. For example, as winter approached, a small generator (under 1 kW demand) was added to the system to provide electric power for the water pumping system. The exhaust from the generator (CO2) was fed to the algae (algae eats CO2) and the heat from the exhaust was passed into the algae water, which provides some warmth for the algae.

The production of algae was lower during this test period due to reduced daylight hours and cooler water temperatures. However, the algae not only survived, it still managed to grow. The controlled environment of the Montana hybrid system has now given GSPI the pathway to significantly improved cold weather production engineering in the next generation system scheduled to start production in the spring of 2008.

Mr. Joseph LaStella, president of Green Star Products, stated, "It has required a lot of high-tech ingenuity to create a low-tech, inexpensive algae production system."

Mr. LaStella further stated, "The winter program has also added a host of other technical changes to our system. For example, reduction in heat loss (radiation and convection heat loss) during cold nighttime hours in winter months."

Steady progress continues on the much larger systems planned for production in 2008 (see press release dated November 13, 2007 titled "GSPI Signs Contract to Build Algae-to-Biodiesel Facility").
