I, Todd B. Crosland, certify that:

1. I have reviewed this  quarterly  report on form 10-QSB of Scientific  Energy,
Inc.,

2. Based on my knowledge, this 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 small business
issuer as of, and for, the periods presented in this report.

4. The small business  issuer'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 small business issuer 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 small
         business issuer, including its consolidated subsidiaries, is made known
         to us by others within those entities,  particularly  during the period
         in which this report is being prepared;

         b)  evaluated  the   effectiveness  of  the  small  business   issuer'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 on such
         evaluation; and

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

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

         a) all significant  deficiencies and material  weaknesses in the design
         or operation of internal  control over  financial  reporting  which are
         reasonably  likely to  adversely  affect  the small  business  issuer's
         ability to record, process, summarize and report financial information;
         and

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

6. The  registrant's  other  certifying  officers  and I have  indicated in this
quarterly  report  whether or not there  were  significant  changes in  internal
controls or in other factors that could  significantly  affect internal controls
subsequent to the date of my most recent  evaluation,  including any  corrective
actions with regard to significant deficiencies and material weaknesses.
