                        THERMODYNETICS ANNOUNCES PLANS TO
            LIST SHARES OF A UK HOLDING COMPANY FOR TURBOTEC PRODUCTS
                    ON THE LONDON STOCK EXCHANGE'S AIM MARKET


WINDSOR, CT - Wednesday, March 15, 2006, OTCBB: TDYT

Thermodynetics,  Inc.  plans to  admit  the  shares  of a  United  Kingdom  (UK)
registered subsidiary to trading on the London Stock Exchange's AIM market.

Thermodynetics has engaged Dawnay, Day Corporate Finance Limited and Dawnay, Day
Townsley  to  act as its  Nominated  Advisor  and  Broker  to the UK  subsidiary
respectively,  and has  engaged  other  advisors  in  London,  to  advise on the
proposed  public  offering of its UK subsidiary  and the admission of its issued
share capital to trading on AIM. It is intended  that the UK subsidiary  will be
the holding company for Thermodynetics' operating subsidiary, Turbotec Products,
Inc.

Shares  in the new UK  company,  which  has been  formed,  will be  offered  for
subscription  and sale to non-US  investors  prior to the  admission  of the new
company's  issued  share  capital  to trading on AIM.  The  public  offering  is
expected to be  completed  in April 2006 and to raise  approximately  $7 million
after all expenses.  The net proceeds of the issue of new shares will be used to
reduce debt, for expansion and for working capital for Turbotec Products Inc.

There can, of course,  be no  assurance  that the offering  and  admission  will
proceed as the process is subject to finalization  and to market  conditions and
the offering will not be underwritten.
