Re: Big Capacitor?

["Steve Cook" <Steve-at-g8cyerichmond.freeserve.co.uk> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

Caps of up to 5F (the largest I have seen) are available at very low
voltages for memory back-up purposes. Physically they are less than 1" in
diameter and only about 1/2" high (at least the ones I have seen are like
this, there are probably varous other forms used). They use very specialised
construction and are very easily destroyed by over voltage.
