Item 3.01        Notice of Delisting or Failure to Satisfy a Continuing Listing Rule or Standard; Transfer of Listing. 

On April 24, 2009, Mechanical Technology, Incorporated (the “Company”) announced it received a Staff Determination Letter dated April 16, 2009, from the Nasdaq Stock Market (“Nasdaq”) on April 23, 2009, stating that the Company’s shares of common stock were subject to delisting from the Nasdaq Capital Market pursuant to Listing Rule 5210(d) for failure to pay all applicable fees as described in the Listing Rule 5900 Series. Since the Company had previously determined to voluntarily delist its common stock from the Nasdaq Capital Market prior to receiving the letter and filed a Form 25 with the Securities and Exchange Commission and Nasdaq on April 16, 2009, which resulted in the delisting of its common stock at the close of trading today, the Company will not appeal the Staff’s Determination.

A copy of the press release that includes this announcement is attached hereto as Exhibit 99.1 and incorporated herein by reference.
