Wow, I had no idea the technology had come so far in such a short span of time. I remember just 10-15 years ago you'd only find a 10F cap in a laboratory setting.

350F in a D size battery is amazing. Not to mention, extremely dangerous. If someone promptly discharged just one of those I can't imagine the amount of damage it would do.

It would be really easy to turn a bunch of these into a portable HERF weapon for electronic warfare, you'd just need a vacuum tube or magnetron that would be able to withstand that kind of power dump.

If the capacity of super-capacitors has gotten so high, why aren't they used in more applications? (or is this leading into the area of conspiracy theories involving "Big Battery"...)
