Thanks Ian for the link to the Panasonic product. That’s an advance in insulation tech I hadn’t known about. I agree. Aptera ought to be taking advantage of this for both battery pack insulation and passenger cabin insulation. The Panasonic VIPs appear to be delicate though, and can’t be bent into sharp curves. If the vacuum is lost in the panel, say, though an accident, then the panel loses 90% of the insulation value. R60 drops to R5. But sandwiched between the water formed aluminum battery cases, or the cabin roof composites, these VIPs could be great.
