GreenMan Subsidiary Signs Agreement With Industry Leader in Alternative Fuel Engine Design

CARLISLE, IA--(Marketwire - November 17, 2009) - GreenMan Technologies, Inc. (OTCBB: GMTI) today announced that its subsidiary, American Power Group, Inc. ("APG") has entered a technical consulting agreement with Robert Natkin, a world-renowned expert in alternative engine technology. Mr. Natkin's work with APG will focus on upgrading and expanding future capabilities of APG's dual fuel products for the diesel-powered vehicular market.

Mr. Natkin spent a progressive 32-year career with Ford Motor Company as a Technical Specialist and Design Technical Leader in the Advanced Engine Department, Advanced Powertrain Technology & Materials Department, and on the Hydrogen IC Engines Program in the Powertrain Research Department. In the past few years, Mr. Natkin has consulted on various Compressed Natural Gas ("CNG") designs and methodologies of achieving full CARB (California Air Resources Board) and EPA emission certification for various alternative fuel products.

Lyle Jensen, GreenMan's President and Chief Executive Officer, stated, "We are elated to have someone with Bob's industry experience endorse our APG dual fuel technology and provide his expertise as we expand our dual fuel capabilities with CNG, bio-methane, and other applicable dual fuel combinations. His vast knowledge of engine designs and emissions criteria will accelerate our in-house development of emission reduction upgrades necessary to meet the new EPA requirements being implemented over the next five years. The EPA recently reported that there are 13 million diesel powered vehicles and 7 million stationary diesel generators in operation in the United States. All of these diesel engines are candidates for APG's alternative dual fuel aftermarket upgrade system which provides the flexibility for an engine to operate on a combination of diesel and CNG or 100% diesel. While running on dual fuel, significant net fuel savings and lower emissions are achieved."

Jensen further stated, "Over the past 100 days, we have made significant progress in expanding our sales and technical support teams and are pleased with the level of interest being expressed by the installed base of diesel engine owners in our products and services. At the end of July, we anticipated that it would take two to three quarters to create meaningful recurring revenues and we believe we are right on track to meet that business objective."
