    THERMODYNETICS ESTIMATES SECOND QUARTER REVENUE INCREASE TO RECORD LEVELS
               WHILE OPERATING MARGINS RETRACT DUE TO METAL COSTS

            THERMODYNETICS EMBARKS ON SEARCH FOR SUITABLE ACQUISITION

WINDSOR, CT - Wednesday, November 1, 2006 - Thermodynetics, Inc. (TDYT: OTCBB)

      We will be releasing financial results on or about November 7th, the date
of our Annual Shareholders' Meeting. In the meantime, we estimate that net sales
of the Company's Turbotec subsidiary for the three and six months ended
September 30, 2006 increased significantly over the prior year period and will
represent a record in any three or six month period.

      The increase in sales is due largely to sales of condenser/evaporator
coils for the housing market augmented by increased sales of enhanced tubing
used in commercial boiler applications. Although there has been some weakening
in residential construction during the past few months, the overall demand has
remained at higher levels than in prior years. A good portion of the increased
sales figures also relate to the pass through of the increased metals costs.
Turbotec's special purpose enhanced surface tubing in titanium is unique to the
swimming pool heat pump system market and a large part of this market niche has
been captured. Turbotec is currently investigating other applications for its
surface enhanced titanium tubing.

      Cost of sales are expected to be higher by several percentage points in
the fiscal periods ended September 30, 2006 vs. 2007, thereby reducing profit
margins. The cost of metals (principally copper and nickel) has risen sharply
during the past two years to record levels, and more significantly, in the few
months since the London IPO; copper prices have moderated toward the end of the
current quarter, while nickel continues to rise unabatedly. The net impact has
been a significant reduction in gross margin and a higher inventory carrying
value. To combat the eroding margin, Turbotec's management is planning on
several initiatives related to sharing costs and increasing prices. Turbotec has
also begun a widespread training program for their employees to improve
efficiencies on the production floor.

      Operating costs also will be higher as personnel were added in customer
service, product engineering and other support functions to support the growth
in sales and new product development. Further staff additions in marketing and
engineering are planned as Turbotec continues to expand its product development
in heat reclamation and titanium based heat exchangers. Interest expense
decreased significantly in both current year periods compared to the prior year
as the May 2006 London public offering of Turbotec was used to retire debt.

      Income from continuing operations will be positive in both the 3 and 6
month periods. The operations of a former manufacturing subsidiary, Vulcan
Industries, ceased in September 2005 and Vulcan will be reflected as a
discontinued operation in the financial statements.

       At September 30, 2006 working capital will be reported in excess of $4
million compared to a negative $1.68 million at March 31, 2006, which was a
result of the May 2006 offering. Aggregate debt related to continuing operations
at September 30, 2006 was also reduced some $3.5 million since March 31, 2006.



      The Company has initiated a search for a suitable acquisition and has
begun to circulate its ideal acquisition criteria which include a) a business in
metals manufacturing, b) having a proprietary product or service, engineering
oriented, c) with net revenues of $6 - $60 million and positive cash flow, d)
continuing management and established sales force, and e) an OEM customer base
with growing market, international preferred. A summary description of a
suitable candidate should be forwarded to Robert A. Lerman, President and CEO.
