GreenMan Technologies Completes Asset Purchase Agreement With American Power Group, Inc.


CARLISLE, IA--(Marketwire - July 29, 2009) - GreenMan Technologies, Inc. (OTCBB: GMTI), today announced the acquisition of substantially all operating assets (excluding patents) and assumed substantially all financial obligations of American Power Group, Inc. ("APG"), an Iowa corporation. In June, GreenMan announced that it had signed a licensing agreement with APG for the worldwide commercialization of its patented dual fuel alternative energy technology.

Lyle Jensen, GreenMan's Chief Executive Officer, stated, "The acquisition of APG's operations positions us to aggressively pursue commercialization of the patented dual fuel alternative energy technology we licensed in June. APG is at the nexus of multiple compelling trends in the marketplace. Its proprietary 'shovel ready' solution significantly reduces a customer's operating cost by reducing reliance on fossil fuel and adding to the useful life of a diesel engine. Not only is this an attractive investment for customers around the world, but it is also environmentally friendly and in concert with the current clean air initiatives in Washington. In conjunction with the acquisition, we entered into long term employment and consulting agreements with APG's senior management team. The system will continue to be marketed under the American Power Group brand name."

APG's dual fuel alternative energy system is a unique external fuel delivery enhancement system that converts existing diesel engines into more efficient and environmentally friendly engines that have the flexibility to run on: 1) diesel fuel and compressed natural gas ("CNG"); 2) diesel fuel and bio-methane, or 3) 100% on diesel fuel depending on the circumstances. The proprietary technology seamlessly displaces up to 70% of the normal diesel fuel consumption with CNG or bio-methane and the energized fuel balance between the two fuels is maintained with a patented control system ensuring the engines operate to Original Equipment Manufacturers' ("OEM") specified temperatures and pressures with no loss of horsepower. Installation requires no engine modification unlike the more expensive high-pressure alternative fuel systems in the market. Additional dual fuel system combinations are under development and will also be covered by this License Agreement.

APG's fuel technology upgrade is ideally suited for the large domestic and international installed base of both stationary and vehicular diesel engines estimated to be in the millions in both the U.S. and internationally. The stationary market includes primary and backup diesel power generation for hospitals, critical care facilities, cold storage warehouses, data centers, financial centers and exchanges and government facilities, while vehicular applications include school buses, public transit, refuse haulers, commercial route fleets, government vehicles, and short-haul trains. Over 1,000 APG systems are already in operation in North and South America, Africa, India and Pakistan.
