Most of the various examples of machines and equipment with Coefficients of Performance greater than unity are covered on this site together with links to other sites - well worth the visit.

Peter Ryalls is asking whether there are other members who would be interested in forming a Group within RPEC to build and test one of these items. In particular somebody who has a workshop or tools that are required would be very welcome. Peter has a garage that could be made available for the project

Members interested should contact Peter directly - he is in the membership lists recently released.
