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
