Nice article. You covered a lot of ground. You compare energy density with respect to mass. Would not a better comparison be with equal volumes? It takes a lot of ultracap to mass the same as a battery. Also, you did not address the issue of temperature reliability. Here in AZ, ambient air can be 50C. If you leave the windows up the passenger compartment gets hot (ok, "hotter" for you coast-bound guys), and under the hood is worse. The Arrhenius curve for ultracaps is quite steep, and even 60C could be a serious degrader of life expectancy.

Thanks for sticking to the facts about ultracaps and leaving the hype in the battery recycle bin!

Of all the exhibits in the Pre-Apocalypse Era Museum, Breek was always in awe of the unearthed details and true-to-scale reproduction of a technological creation space that the long gone humans had once inhabited.
