MTI REPORTS SECOND QUARTER 2008 RESULTS

- Business and technical advances -

Albany, N.Y., August 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 June 30, 2008.

In connection with second quarter results, Peng Lim, Chairman and CEO of MTI commented, “At MTI Micro, we signed agreements with two consumer electronics OEMs – NeoSolar and a global Japanese consumer electronics company – an achievement that, based on public announcements, has not been matched by any other company in the micro fuel cell industry. In preparation for the anticipated commercialization of Mobion^? in the second half of 2009, we continued to expand our global operations by setting up a representative office in China to develop relationships with manufacturers and low-cost component suppliers, and we received further funding from the Department of Energy for the development of manufacturing techniques for our Mobion^? platform. MTI Micro also achieved important life testing metrics, and unveiled a GPS prototype capable of providing three times as much energy as GPS devices powered by four disposable AA batteries. At MTI Instruments, as a result of soft global economic conditions, we are now projecting a sales decrease of between 10 to 15% for the year; however, with a clear focus on the future, we continue to work on new product introductions and marketing efforts to position MTI Instruments for increased sales when general economic conditions improve. In the second quarter, we unveiled the PV1000, a thickness measurement system for the rapidly growing solar industry. The PV1000 can be incorporated into solar cell production lines to help manufacturers quickly determine quality control issues, saving them time and money.”

Recent Developments

•

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%.

Second Quarter Financial Results

Revenue for the three months ended June 30, 2008 decreased 22.8% to $2.0 million compared to revenue of $2.6 million for the same period in 2007. Second quarter revenue included $1.7 million in product revenue from MTI Instruments and $309,000 in funded Research and Development (“R&D”) revenue from MTI Micro. During the second quarter of 2008, product revenue decreased $555,000, or 24.4%, reflecting sales decreases in MTI Instruments’ general gauging and aviation product lines – partially offset by smaller sales increases in semiconductor products. Funded R&D revenue decreased $44,000, or 12.5%, reflecting a revenue increase from MTI Micro’s contract with the DOE of $166,000 which was more than offset by revenue decreases of $210,000 attributable to the conclusion of a strategic alliance agreement and a contract in 2007.

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 contracts, our test and measurement instrumentation business is no longer expected to generate double-digit sales growth in 2008. Based upon current global market conditions, we estimate that the

test and measurement instrumentation business will experience a sales decrease of around 10 to 15% for fiscal year 2008 compared to 2007.

Net loss for the three months ended June 30, 2008 was $3.3 million, or $(0.69) per diluted share, compared with a net loss of $2.5 million, or $(0.52) per diluted share for the same period in 2007. Net loss for the second 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, decreases 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.

We are currently implementing a series of strategic cost reduction efforts throughout the organization with a goal to reduce our monthly consolidated cash burn by the beginning of our fourth quarter 2008. These cost reductions will be accomplished through numerous initiatives, including the elimination of certain non-core functions, outsourcing certain activities, and the deferral of non-critical capital expenditures.

Cash flows: For the three months ended June 30, 2008, cash used in operations increased by 13.8% to $3.6 million compared to $3.1 million in 2007, while cash used for capital expenditures decreased to $83,000 from $190,000 in 2007.
