We’ve had some interesting discussions here recently about the ‘H-Cat’, an open source experimental effort to generate excess heat by combining HHO gas with catalysts found in automobile catalytic converters. There seems to be a growing interest in this effort, and a number of people are attempting to replicate the effect and improve upon it.
Justin Church and Neal Ward, who have been commenting here on ECW about the topic, have launched a new forum, called the H-Cat Forum, as a resource for people who want to get involved in this effort.
The H-Cat forum can be accessed at this address: http://app.hydrofuel.ca/ At the moment, in order to read the posts there you have to be a registered member — anyone can sign up for free.
