Here is a GEET mailing list. Freely disseminating results will ensure the quickest development. Put up some pictures of what you have done. For example, here is a GEET experimenter who has converted a Geo Metro. And here is another GEET experimenter.
Advanced testing is needed There are reports of very interesting modes of operation.
For instance, one experiementer in New Zealand has been able to operate his engine in a closed loop mode, which Paul Pantone has also reported. This is remakable, and access to university level equipment, such as a gas chromatagraph or a mass spectroscopy machine, would allow further characterization of the gas which is being made by the GEET device. Some surprises may be in store. Exotic materials may be of interest. Pipes of high nickel content stainless steel, or use of platings of platinum, might achieve higher efficiencies.
