here is what I am settling on for the first prototype of the Shewbread Capacitor.

any idea's to add?

[onthecuttingedge2005]

just a reminder.

for the shewbread capacitor.

1. remove the bread crust off of the bread with a razor blade.

2. use a mold or a flat plate(not to heavy) and place it on top of the bread to keep the shrinking of the bread from deforming the bread while it is being converted to carbon. if the plate is to heavy you might lose some of your porousness in the carbon once toasted to a charcoal consistency.

3. use proper ventilation when over toasting your bread. lots of smoke!

4. when selecting your bread of choice, look for the amount of pores per square centimeter, the greater the pores the better the surface area.

5. ask yourself, why did he call it a shewbread capacitor? look up shewbread on wiki and you'll find out why I called it a shewbread capacitor.

6. try to get the burnt toast as close to 99% converted to porous carbon and to make an analogy of this, it is a burnt offering before the Lord. lol

7. just to make this more weird, I am a son of David and a Carpenter. for those are names not professions. I have been drinking a little but I have not told any untruth.

I always get spiritual when I am drinking, I guess it is the spirits in the drink! I do apologize for all those atheists. I do try to keep this on a professional level when I am sober though. but hey. it is Thanks Giving and so. I am giving.

8. remember, if you become rich off of my idealism then please contribute to my spaceship, I would greatly appreciate it. I have a spaceship to build.

after a kitchen full of smoke from toasting the shewbread to a pitch black peace of carbon the conductivity test is successful.

the peace of burnt toast measures 1/4 inch in thickness and measures 23M ohms in resistance from backside to front side. this is a good sign.

it will help if a flat weight is placed on the shewbread while toasting to prevent deformity of the bread so that the bread remains flat.

after the thanksgiving festival I will assemble the Ultra cap pile to test for capacitance.

happy thanksgiving to all.

Hi Jerry,
interesting idea with the burnt toast, but:
1. You should definately do that outside as inhaling the smoke is dangerous
2. 23 MOhms is much too unconductive !

Just use the method to fire up a few coal briquets and let them
glow hot red for a while and when they have a white ash surface
and will still glow inside, then the carbon from the coal has transformed
to a very good conductive graphite...

They then look as if they have almost completely burnt up,
but when you put them into a metal box, so it kills the oxygen air supply,
the burning will stop and inside the white ash they will still
have black powder, which is the graphite.

( Be careful, the metal box will get very hot
as they have stored a lot of heat energy, when they
still glow read hot !)

This graphite then will have about 10 to 100 ohms per cm distance,
which is very nicely conductive.
This good conductivity is needed for a good supercap.

Regards, Stefan.

Graphite powder can be easily bought online. It's about 10 euro/kg, e.g:

What a great thread! Here's a good forum on ultracaps that includes numerous threads on how to make homemade ultracaps,

http://www.ultracapacitors.org/

Here's one thread, titled, "Home made supercaps"
http://www.ultracapacitors.org/index.php?option=com_fireboard&Itemid=99&catid=8&func=view&id=339

If someone has a program to backup this thread, then that would be great in case something happens to it. This guy go into detail how to make a DIY supercap. Some of these DIY supercaps are at least 150F.
