Sustainable Technology and Energy for Vital Economic Needs

Two S.T.E.V.E.N. Foundation solar ovens being tested at Cornell University in May, 2004.
A team of students from the national organization Engineers for a Sustainable World undertook the
tests as part of a course in the College of Engineering at Cornell.  Their work has led to an updating of the
solar oven design manual, and also an interim report on the project which is available below under
"Position papers, proposals, and reports"

S.T.E.V.E.N. Foundation on hiatus:

The S.T.E.V.E.N. Foundation at its 2016 annual meeting took the decision to enter into a hiatus period.  For the foreseeable future, we will continue to maintain this web page as a service to the appropriate technology community.  However, we will not continue the publication of the annual newsletter, nor add new content to this page.  You may still contact us at the address below.  Best wishes from all of us -- it has been a remarkable ~25 years, and we are grateful for having had the opportunity to serve.

Description of the S.T.E.V.E.N. Foundation

The S.T.E.V.E.N. Foundation was incorporated in New York in 1986 by Prof. Jaroslav
Vanek of Cornell University, and has non-profit status under provision 501(c)(3) of United
tax law. The word "S.T.E.V.E.N." stands for Solar Technology and Energy for Vital
Economic Needs. In exploring the low-cost exploitation of solar energy, it is the desire of the
Foundation to make available to all people, but especially the poor and disadvantaged,
inexpensive alternate sources of energy for development and economic viability. Furthermore, it
is the intention that these technologies be used through cooperative entities, either family groups
or worker/community cooperatives which can both produce and operate them.
