Have you ever had a cap blow on you?! I have, it's not fun, reverse polarity... the end vent opened right up, filled a large portion of my room with steam from the electrolyte. Very stinky :020: :036:

Ya, the new Super-Ubar-Ultra Caps from that group from MIT uses Nano carbon tubes like hair that drastically increase capacity and current. They claim 60Wh/kg gravimetric density. EStor, another company claim i think ~120-150 Wh/kg, IMPRESSIVE. For a capacitor.
