Exhibit 31.1

                                 CERTIFICATIONS

I, Emanuel N. Logothetis, Principal Executive Officer of Joule, Inc. certify
that:

     1.   I have reviewed this annual report on Form 10-K of Joule Inc.;

     2.   Based on my knowledge, this annual report does not contain any untrue
          statement of a material fact or omit to state a material fact
          necessary to make the statements made, in light of the circumstances
          under which such statements were made, not misleading with respect to
          the period covered by this report;

     3.   Based on my knowledge, the financial statements, and other financial
          information included in this report, fairly present in all material
          respects the financial condition, results of operations and cash flows
          of the registrant as of, and for, the periods presented in this
          report;

     4.   The registrant's other certifying officers and I are responsible for
          establishing and maintaining disclosure controls and procedures (as
          defined in Exchange Act Rules 13a-15(e) and 15d-15(e) for the
          registrant and have:

               a)   designed such disclosure controls and procedures, or caused
                    such disclosure controls and procedures to be designed under
                    our supervision, to ensure that material information
                    relating to the registrant, including its consolidated
                    subsidiaries, is made known to us by others within those
                    entities, particularly during the period in which this
                    annual report is being prepared;

               b)   evaluated the effectiveness of the registrant's disclosure
                    controls and procedures and presented in this report our
                    conclusions about the effectiveness of the disclosure
                    controls and procedures as of the end of the period covered
                    by this report based on such evaluation; and

               c)   Disclosed in this report any change in the registrant's
                    internal control over financial reporting that occurred
                    during the registrant's most recent fiscal quarter (the
                    registrant's fourth quarter in the case of an annual report)
                    that has materially affected, or is reasonably likely to
                    materially affect, the registrant's internal control over
                    financial reporting; and

     5.   The registrant's other certifying officers and I have disclosed, based
          on our most recent evaluation of internal control over financial
          reporting, to the registrant's auditors and the audit committee of
          registrant's board of directors (or persons performing the equivalent
          functions):

               a)   all significant deficiencies in the design or operation of
                    internal control over financial reporting which are
                    reasonably likely to adversely affect the registrant's
                    ability to record, process, summarize and report financial
                    data and have identified for the registrant's auditors any
                    material weaknesses in internal controls; and

               b)   any fraud, whether or not material, that involves management
                    or other employees who have a significant role in the
                    registrant's internal control over financial reporting.
