MTI REPORTS THIRD QUARTER 2008 RESULTS

- Business and technical advances support commercialization plans -

Albany, N.Y., November 14, 2008 -- Mechanical Technology, Incorporated (“MTI”) (NASDAQ: MKTY), a company primarily engaged in the development and commercialization of Mobion^® off-the-grid portable power solutions through its subsidiary MTI MicroFuel Cells Inc. (“MTI Micro”) and in the design, manufacture, and sale of test and measurement instruments and systems through its subsidiary MTI Instruments, Inc. (“MTI Instruments”), today announced its financial results for the quarter ended September 30, 2008.

“This quarter, MTI Micro continues to make progress toward Mobion manufacturing readiness, signed agreements with new customers, demonstrated significant advancements in our technology, and filed our 100^th patent application – these important developments move us closer to achieving commercialization plan in the later part of next year,” said Peng K. Lim, Chairman and CEO of MTI. “At MTI Instruments, despite the slow down of the worldwide economy, we continue working on new product innovations and focusing our marketing efforts to position the business for a sales rebound when economic conditions improve.”

Recent Developments

•

September 30, 2008 – MTI announced that Rodney A. Tillinghast, Corporate Controller and Director of Financial Reporting for MTI, was named Interim Chief Financial Officer and Secretary of the Board of Directors, effective September 26, 2008.

•

September 18, 2008 – MTI Micro announced that its third generation Mobion^® Chip improved power performance by approximately 25% as compared to the previous generation unveiled during June 2007. In laboratory testing, the Mobion^® Chip demonstrated power of over 62 mW/cm² while producing more than 1,800 Watt Hours per Kilogram (Wh/kg) of energy from the direct methanol fuel feed. In addition to the ongoing power performance improvements, the third generation Mobion^® Chip was approximately 25% smaller than the prior generation was in June 2007 and over 50% smaller than the initial generation was at the beginning of 2007.

•

August 26, 2008 – MTI announced that it had applied to transfer its common stock listing from the Nasdaq Global Market to the Nasdaq Capital Market. The

application for transfer into the Nasdaq Capital Market was accepted on September 3, 2008 and the transfer became effective September 5, 2008.

•

July 11, 2008 – MTI Micro announced that it achieved 2,700 hours of continuous operation with a Mobion^® laboratory cell — the building block of the Mobion^® Chip and systems. In addition to the 2,700 hours of continuous run-time, MTI Micro’s Mobion^® test successfully demonstrated a significant achievement by showing power degradation of less than 15%.

•

July 9, 2008 – MTI Micro and NeoSolar, a Korean manufacturer of portable digital devices and energy products, announced that they entered into an agreement for the development of Mobion^® fuel cell technology for use in future models of NeoSolar portable digital devices, including ultra mobile portable computers. Both MTI Micro and NeoSolar are working together to develop, test, and evaluate Mobion^® prototypes for their integration with a number of NeoSolar products, which could lead to the use of external Mobion^® power sources, like chargers, snap-on attachments, and embedded Mobion^® power sources, for integration into various digital products.

Third Quarter Financial Results

Revenue for the nine months ended September 30, 2008 decreased in comparison to the same period in 2007 by $1.1 million, or 17.4%, to $5.1 million. The revenue decrease was chiefly attributable to a $1.2 million decrease in general dimensional gauging sales, driven by significantly lower sales to a Japanese OEM. This decline was partially offset by an increase of $509,000 in semiconductor products due to sales expansion in international markets and the sale of a fully automated tool in the third quarter. Aviation sales declined by $396,000 between periods due to declining activity with the U.S. Air Force.

As a result of general global economic conditions, including weaker than expected demand in Japan for photolithography equipment, slower than expected dimensional gauging sales, reduced sales demand within the commercial aviation industry, and the deferral of certain orders under our existing U.S. Air Force contract, we estimate our test and measurement instrumentation business will experience an annual sales decrease of between 25% to 30% for 2008 compared to 2007.

Net loss for the nine months ended September 30, 2008 was $10.5 million, or $(2.20) per diluted share, compared with a net loss of $8.1 million, or $(0.84) per diluted share for the same period in 2007. Net loss for the third quarter of 2008 compared to 2007 includes decreases in gross margins on product sales, decreases in funded R&D revenue, cost savings in R&D spending, increases in selling, general and administrative expenses, a decrease in gain on derivatives, gains on the sale of securities available for sale, and a decrease in the income effects of minority interest stockholders.

Cash flows: For the nine months ended September 30, 2008, cash used in operations decreased by 20.6% to $8.5 million compared to $10.8 million in 2007, while cash used for capital expenditures decreased to $190,000 from $281,000 in 2007.

At present, MTI does not expect to advance future resources to fund MTI Micro, and MTI Micro will instead seek external financing to fund its research operations. Excluding any funding necessary to support MTI Micro's operations, MTI current expects that its current cash, marketable securities, and the future results of operations from MTI Instruments are expected to provide sufficient liquidity for MTI through at least December 2009. During September 2008, MTI Micro closed on $1.5 million of funding from external investors in the form of secured convertible notes.
