WALTHAM, Mass., Dec. 22, 2011 /PRNewswire/ -- Tecogen Inc., a next-generation manufacturer of natural-gas-fueled, engine-driven, combined heat and power (CHP) products that are designed to reduce energy costs, reduce greenhouse gas emissions, and alleviate congestion on the national power grid, today announced that it has filed a Form S-1 Registration Statement (Form S-1) with the U.S. Securities and Exchange Commission (SEC).

The Company is registering for resale shares of common stock under the Form S-1, held by existing stockholders, including affiliated persons that hold restricted stock. The Company will not receive any proceeds from the sale of shares by the selling stockholders. The Company intends to take steps to quote its common stock on the OTC Bulletin Board or list its shares on a national or international securities exchange, upon becoming a reporting entity under the Securities Exchange Act of 1934 and when market conditions allow.

Tecogen was formed in the early 1960's as the Research and Development New Business Center of Thermo Electron Corporation (which is now Thermo Fisher Scientific Inc.), and in 2000 Tecogen was sold to private investors including Thermo Electron's original founders, Dr. George N. Hatsopoulos and John N. Hatsopoulos.

The Form S-1 has been filed with the SEC but has not yet become effective. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective.  This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to their registration or qualification under the securities laws of any such state or jurisdiction. This offering will be made only by means of a prospectus. A copy of the prospectus may be obtained from the offices of the Company at 45 First Avenue, Waltham, MA 02451, attention John Hatsopoulos and is also available at the SEC's website at: www.sec.gov.
