They're pretty explicitly marketing it as a "range extender" for hybrid electric vehicles. In the mockups in the article it seems like they don't have a traditional gearbox, so it sure looks like they're intending to suggest running it as a straight-up electrical generator even when mounted in a car. Neat application of the concept. Diesel locomotives have worked this way for a long time.
