ok, I know some of you are engineering types. I am starting to look at the idea of home building a fuel cell here that can power my machines "off the grid" if need be. I am not worried about the fuel source itself (hydrogen can be easily got with some solar cells, graphic electrodes and starage media). What I am worried about is this: 1. Building one cheaply 2. available materials (preferably from lowe's or home depot) with the exception of the electrolytic material and possibly the catalyst materials) 3. a method of containment (A good quality housing that will keep the 2 parts of the fuel seperate until introduced into the catalyzing chamber) any other suggestions that would help. In a way, this would be a different sort of open source project. I am not looking to make this proprietary and would love to have a means of backup power for extended periods (especially considering how expensive electricity and natural gas are going to get in the not too distant future). any good ideas will help. I'd like to be able to engineer and assemble a small test unit in my garage with only a minimal of technical know-how (I can learn if I have to). - Eric --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
