I recently helped my son do his 6th grade science project. The premise of his project was that capacitors could and eventually would be able to replace traditional batteries and that there would be not only an economic, but an environmental benefit as well. OK, I might have influenced him a little bit on his thesis.
We used Arizona Capacitors, of course, as well as Tepro of Florida resistors on our PC board. We ended up with 6 capacitors and 19,000 uf. Two switches were installed so that he could cut off the main power and show that the LED light bulb was running exclusively from the charged capacitors. The experiment was a success and he was able to run the light bulb (visible to the naked eye) for 4 minutes and 59 seconds, in a dark environment.
I just wanted to say thanks to Richard our head of engineering for his generous help with this project. I guess it's just a matter of time before we see more instances of capacitors acting as batteries in everyday applications.
