Item 5.   Other Events.

     Plug Power, LLC ("Plug Power"), a joint venture between Mechanical 
Technology Incorporated and DTE Energy Company, recently finalized a series
of agreements with GE On-Site Power ("GEOSP"), a wholly-owned subsidiary of 
General Electric Company which is controlled by the GE Power Systems Division, 
to create a joint venture company, GE Fuel Cell Systems ("GEFCS"), to 
distribute Plug Power fuel cell systems worldwide.  The agreements provide that
GEFCS will market, sell, install and service Plug Power designed and 
manufactured fuel cells for residential and small commercial power applications
on a exclusive basis.  The size of the units will range up to 35kW and all units
sold will contain both the GE and Plug Power brand name.  The agreements require
Plug Power to meet certain defined quality, price, engineering, design and 
production standards.  GEOSP will own 75%, and Plug Power will own 25%, of 
GEFCS.  In addition, GEOSP now owns approximately 10% of Plug Power, with 
options to purchase approximately an additional 10%.  GEOSP's interest in Plug
Power will be reduced if GEFCS is terminated prior to the end of its initial 
5-year life or if GEFCS does not meet specified financial obligations.  As part
of the agreements, Plug Power will work closely with GE's Corporate Research &
Development Center.  Implementation of the transactions contemplated by the 
agreements requires adoption of a product development schedule and execution of
additional agreements with GE's Corporate Research & Development Center.
