I suggest that there Be a Files Section added so all the diagrams pictures etc . can be posted in one place Zipped up in the  name of the thread  so we can have all the information in one file and one place the files section ... Anyone Second the Motion  ?

I Agree, and here is my contribution.

I second the motion too.
I have nothing to contribute at this time though.

well that sites interesting, but i think he got his math confused either that or google is wrong. according to a quick search done by google it determined 1f was 1amp and of course batteries are rated in mah, but usually have 2.7 amps of rated charge, now granted a capacitors voltage drops with the energy stored at a relatively calculated rate so its 5v 5a then 4v 4a but lets face it with a nickel metal hydride battery being at the best ive seen 3.6a and bill finding a cap for 400f or 400 amp according to google. theres no competition,.

Amps measure the rate of current flow, which includes a time variable, so they cannot be used as units of charge as you are implying!  1 Farad equals 1 Coulomb, which in turn is the charge a capacitor will aquire with 1 amp flowing for 1 second for its potential difference to increase by 1 volt.  Whereas the battery capacities you quote are in amp-hours...
