GreenMan Technologies Retains O'Neill and Associates

LYNNFIELD, MA--(Marketwire - August 3, 2009) - GreenMan Technologies, Inc. (OTCBB: GMTI), today announced that it has retained the services of O'Neill and Associates, a leading full-service government affairs and public relations consulting firm. O'Neill and Associates will assist GreenMan's management team in working with government entities including the Environmental Protection Agency (EPA), the Department of Transportation, and the Department of Energy. O'Neill and Associates will concentrate heavily on programs and federal funding associated with the Recovery and Reinvestment Act.

Lyle Jensen, GreenMan's Chief Executive Officer stated, "Through our recently announced acquisition of American Power Group, GreenMan has realigned its business focus to encompass a patented dual fuel alternative energy technology which reduces emissions, provides an alternative fuel for diesel fuel, and extends the useful life of a diesel engine. We believe the benefits of our dual fuel technology make the company eligible for many of the stimulus programs identified in the American Recovery and Reinvestment Act. With their public policy expertise, we believe O'Neill and Associates is explicitly qualified to assist us in matching our new capabilities with environmental and alternative energy initiatives that improve our air quality and reduce our dependence on foreign oil."

"We are excited to be part of such a transformational technology which has nothing but positive implications for our economy and environment," said Thomas P. O'Neill III, Chief Executive Officer, O'Neill and Associates.

Mr. Jensen further stated: "There is no question that GreenMan's dual fuel technology aligns perfectly with many of the energy efficiency and energy independence goals sought by several of the stimulus programs. The retrofitting of stationery generators and vehicular diesel engines to run substantially on compressed natural gas or bio-methane is a proven solution with over 1,000 installations around the world. GreenMan's technology is fully developed and installations are already being proposed under the stimulus programs. The technology is 'shovel ready' and its benefits are immediate. Job creation has already commenced."

GreenMan will work with O'Neill and Associates not only in Washington, but at the state level as well. Opportunities in both power generation for buildings and alternative fuel truck/ bus fleets are currently being investigated in several states where both entities have strong networks.
