On March 15, 2007, Mechanical Technology Incorporated (the "Company") issued a press release announcing its financial results for the quarter and year ended December 31, 2006. The full text of Company's press release is furnished as Exhibit 99.1 hereto. This Item 2.02 of this Current Report on Form 8-K and Exhibit 99.1 hereto are furnished pursuant to Item 2.02 of Form 8-K and are not intended to be incorporated by reference into future filings under the Securities Exchange Act of 1934 or the Securities Act of 1933 unless expressly incorporated by reference in such filings.

On March 9, 2007, the Board of Directors of the Company committed the Company to a plan (the "Plan") to suspend the high power development program of MTI MicroFuel Cells Inc. ("MTI Micro") in which the Company will reduce its workforce by approximately twenty percent (20%) of its positions with the intention of significantly reducing spending, currently estimated to be $4.3 million for the remainder of 2007 and $5.8 million on an annual basis reflecting employee and development cost reductions, while maintaining the research, development and commercialization capabilities needed to advance the Company's consumer market programs. The Plan was approved in response to decreased funding and sales opportunities in the military market and commenced on March 14, 2007. The majority of actions required under the Plan will be completed within approximately four weeks, and the Company expects the severance obligations under the Plan to be substantially settled by the end of April 2007. The Company expects to incur one-time charges of approximately $332,000 in the first quarter of 2007, primarily associated with severance benefits.

The Plan constitute an exit or disposal plan activity under FASB Statement of Financial Accounting Standards No. 146, Accounting for Costs Associated with Exit or Disposal Activities, which will result in material charges under accounting principles generally accepted in the U.S. Substantially all of these charges are expected to be cash expenditures.

The Plan is also described in the Company's press release, dated March 15, 2007, referred to Item 2.02 above and attached to this Current Report on Form 8-K as Exhibit 99.1.
