I saw that article but not sure if is related or not. They are located in the same county as WSGI. Im looking up more on their website now. (edit - check out the press release section of the site. very impressive)

From what I have read in academic papers it looks like the two competing factions are parallel vs. serial hybrid drive propulsion systems. I also read that it was generally a clutch issue that was slowing down direct drive hybrid propulsion but I could be wrong. Are there any engineers out there that can help explain and give their opinion considering the lack of extra thrust needed for takeoff (LTA vs. HTA) and altitude?
