Cap Building Site

I can charge one of my .22F super caps from my earth battery and light an led with it (after disconnecting from the charging source) for over two hours.

interesting, is there a formula that one could use to see how many mAh a CAP can deliver? like a ratio between F and Ah ? In your example you have an LED and a .22F cap (how many volts?) , have you measured how much current does the LED consume?

Or, a way for regular caps that perform like a battery?  thanks.

I was also thinking about this lately. Probably arrays of caps would do the job, or...?

@ Prometei:

The volts on this cap are 5.5.  I don't really know what the mA's are for the led.  The Radio shack packaging that came with this one says 1.5 vdc and 20 mA but I have been lighting it with a lot less than that. (as far as amps go)  These things work more like batteries than capacitors in my experience with them. I don't know about a formula, I am in over my head on many aspects of this.

hey folks, I've bumped into this video on youtube http://www.youtube.com/watch?v=PFcylXFGTgk

Batacitor, interesting concept, too bad they don't explain how it works

Interesting video and I share your disappointment in no explanation or drawings on how it works.  This looks a lot like a device I ran across that is supposed to cut down your home electric bills by 50%.  If I can find the link..I will post it below...might be related technology.

from their FAQ

11. How does the Powersaver 8 work?
All electrical supply is subject to surges from time to time, which result in spikes or parasitic peaks that cannot be used by your appliances as working power. These spikes simply waste your electricity. Worse still, they result in overheating, which shortens the life of your appliances and wiring. In the most extreme cases this can cause burns, blow outs and power cuts. Our Powersaver 8 uses a capacitor system to stabilize the flow of electricity. It reduces the spikes in the supply, protecting against surges. The system improves the power factor of your electricity and reduces your electricity bill by on average 20 - 40%.

So they are using caps, hmm, I wonder when they will post the schematics , ehehe
