Did you ever short a high capacity cap in the dark?

It makes a spark, doesn’t it?

Did you ever short a high capacity cap in the dark?

I did once it blowed up really good (of course the voluminous amounts of toxic vapors were not really expected...)

Think of a neighborhood transformer exploding.

LOL!! Boy, the stories I can tell you about accidentally shorting and blowing up capacitors while working on amplifiers and other equipment. A decent sized capacitor sounds like a gun going off when it pops.

On a more serious note, Capacitors are not meant for storing electricity on a long term basis. Yes, they charge quickly at high voltages but you're not going to run a car on a "charged capacitor."

This isn't "back to the future" and there's no such thing as a flux capacitor. Yet another "breakthrough battery scam" IMO.

Have you ever dropped a lit match into a bucket filled with gasoline? Same risk of a fiery death exists with any form of energy storage. A fully charged ultracapacitor would probably be safer to operate than say piping your home with natural gas or propane. Risk aversion is killing technical innovation in this country.
