     Plug Power, LLC ("Plug Power"), a joint venture between Mechanical 
Technology Incorporated and DTE Energy Company, recently received 
preliminary approval from its Board of Managers concerning its 
understanding with GE Power Systems, to brand, market and distribute Plug 
Power's residential fuel cells through a joint venture marketing subsidiary 
("GE Joint Venture").  Negotiations concerning the GE Joint Venture are 
progressing, however, certain key business terms remain unresolved.  There 
is no assurance these business terms will be resolved or that the 
transactions contemplated by the GE Joint Venture will be successfully 
completed.  Below is a press release issued by Plug Power and GE Power 
Systems on September 10, 1998, announcing their intention to enter into the 
GE Joint Venture.

Press Release

                     GE POWER SYSTEMS, PLUG POWER FORMING

            "GE FUEL CELL SYSTEMS" TO MARKET FUEL CELLS WORLDWIDE

SCHENECTADY, NY (Date) - GE Power Systems and Plug Power have signed a 
memorandum of understanding to form "GE Fuel Cell Systems," a joint venture 
that will sell, install and service Plug Power-designed and manufactured 
fuel cell systems. Today's announcement follows Plug Power's recent 
demonstration of a prototype residential fuel cell system that produces 
more than enough power to meet the energy requirements of an average-sized 
home.

Under the terms of this understanding, GE Fuel Cell Systems will distribute 
Plug Power fuel cells for residential and small commercial power 
applications. GE will be Plug Power's exclusive distributor for fuel cell 
systems worldwide, except for Michigan, Indiana, Ohio and Illinois.  As 
part of its fuel cell commercialization approach, GE plans to partner with 
a select number of gas distribution companies, electric utilities, electric 
service companies and power marketers. All fuel cell products sold by GE 
will carry both the GE and Plug Power brands.

"Commercializing innovative new technologies is part of our strategy to 
build the GE brand across a wider range of product and service solutions 
for the entire energy industry," said Robert L. Nardelli, president and 
chief executive officer of GE Power Systems.

Fuel cells offer a clean, quiet and cost-effective alternative for 
customers looking to eliminate the cost and inconvenience associated with 
unexpected power outages. In many areas, fuel cells also will provide an 
attractive alternative to grid-supplied power, with 3 to 5 year paybacks 
possible.

Fuel cells operate by converting fuels such as natural gas or propane to 
electricity through an electrochemical process, rather than combustion. The 
benefits of fuel cells include high electrical efficiency and reliability, 
low operating and maintenance costs, and near zero emissions of particulate 
matter and other pollutants. Fuel cell systems can be sized to match

consumers' specific energy requirements.

"Plug Power's mission has always been to bring to market the highest 
quality line of fuel cell power systems, and provide world-class customer 
support," said Gary Mittleman, Plug Power president and CEO. "Partnering 
with GE  gives us access to the technical expertise, market presence, 
service infrastructure and brand recognition of the world's leading energy 
technology and services company."

In June, Plug Power demonstrated its proprietary Plug Power 7000, a 7-
kilowatt (kW)  residential power system. The demonstration marked the first 
time a fuel cell has been used to meet a home's complete electricity 
requirements. The sale of test units is expected to begin early next year, 
followed by commercial units in the year 2000.

Plug Power said that its initial units will operate on natural gas, propane 
or methanol and can achieve 40% electrical efficiency in simple-cycle 
operation. When excess heat generated by the fuel cell is captured and re-
used, overall efficiency can reach 70% - 85%. To date, fuel cells have not 
been a desirable option for on-site power generation due to their 
relatively high cost. Prices are expected to fall dramatically, however, as 
production volumes increase and manufacturing efficiencies are achieved. In 
mass production, a residential fuel cell system is expected to retail for 
$3,000-5,000. At these prices, fuel cells can generate electricity at 7-10 
cents per kilowatt hour, depending on the fuel costs in a given market.

About Plug Power
     Based in Latham, NY, Plug Power is a joint venture between DTE Energy 
Company (NYSE:DTE), parent company of Michigan's largest utility, and 
Mechanical Technology Inc. (OTC BB: MKTY), an early developer of fuel cell 
technologies. Plug Power was formed to develop and manufacture fuel cells 
for electric power generation in residential and automotive applications. 
Formed in June 1997, Plug Power has grown from 22 to more than 135 
employees, and expects to expand to 300 when it begins mass manufacturing 
of commercial units. The National Energy Resources Organization awarded 
Plug Power the 1998 Research and Development Award for its fuel cell 
breakthroughs.

About GE Power Systems
     GE Power Systems is one of General Electric's major businesses and is 
the world's leading supplier of power generation technology, energy 
services and energy management systems. GE Power Systems serves customers 
globally through a network of local offices and service centers.

The MOU with Plug Power is the latest in a series of actions by GE to 
broaden its participation in the small power generation market. In 1994, GE 
acquired Nuovo Pignone, an Italian-based manufacturer of small gas 
turbines, pumps and compressors. In early 1998, GE completed the 
acquisition of Stewart & Stevenson's Gas Turbine Division, which has 
significant experience in packaging and servicing small power generation 
equipment. That business now is known as S&S Energy Products. In May 1998, 
GE entered into a distribution agreement with Elliott Energy Systems, which 
provides GE global rights to sell and service Elliott's line of Turbo 
Alternatorsr. With the Plug Power relationship, GE's portfolio of power 
generation products will extend from 7 kW  up to 450 megawatts (450,000 
kW).
