The issue with the PowerPoint is two-fold: first, I'm trying to figure out exactly what SolarEVolution.com is  is it an advocacy site?  It seems to be a collection of links, but I can't quite determine what the purpose of the organization is, so it's tough to know what we're looking at.  The PowerPoint seems to be straight from UniModal, complete with invisible-to-the-audience notes about how to make a strong case for SkyTran  but it doesn't say who made it, and even if we knew it was from UniModal, it's not an independent, third-party source.  It does strongly hint that such content may exist somewhere, though.  Thanks for being patient with me and the fact-finding process.  It's really frustrating, I know, to personally know a thing is likely true, but not be able to find supporting evidence for it for an article.  But reliable sources will turn up, and then the article will be both reliable and thorough in its coverage. ''''''     JDiscourse
