The capacitor I was screwing with was about 1/3-1/4 the size of that one too. I pay attention to the warning labels now.... Quote Share this post Link to post Share on other sites
Dumpster 0 #31 April 15, 2005 What's the farad rating on that? 58 farad or .58 farad? Can't read it it's a little blurry- Easy Does It Quote Share this post Link to post Share on other sites

billvon 3,114 #34 April 15, 2005 >How does it work? What does it use to store power? It's a capacitor. In its simplest form, a capacitor is two insulated metal plates close to each other. Put a lot of electrons on one plate (i.e. give it a 'negative charge') and they will stay there until you take them out. Capacitors are all over - you probably have 200 of them in your computer alone - but until recently could only store small amounts of charge in them. Now they are a lot better.

SkydivingNurse 0 #35 April 15, 2005 what's the farad rating on that thing? I still remember the fun I had chasing the other EM's on my ship around with a charged picofarad capacitor. Quote Share this post Link to post Share on other sites
billvon 3,114 #36 April 15, 2005 >if it would take ten seconds to charge it, what sort of charger would >it need. A massive one. You'd need as much power as your average city block if you wanted to do it in ten seconds. It would be big enough that you'd want to permanently mount it on a pedestal at a gas station or something. >If I had a hybrid, and electric was supplied by this capacitor, would >it take three hours to charge it off the the power generated by the > car motor? If it was a hybrid, it would take (calculator time) about 5 minutes to fully charge the pack I described above, assuming a 25kW motor/generator and a pack made up of 300 modules. Of course, in your typical hybrid, the battery never gets fully charged or discharged; it just 'smooths out' the peaks and valleys of power demand from the engine.

Space shuttle fuel tanks was my other favorite... and we have to be able to work football fields into this somehow... Would these things suffer any signifigant life degredation if you charged them really quickly? say, by using another, higher capacity cap? Quote Share this post Link to post Share on other sites

Dumpster 0 #46 April 15, 2005 Gawd that seems huge - 10 Years ago a few of us ham-radio geeks were sitting in our club shack wonder how big a full 1-farad capacitor would have to be, let alone 58 farad. (We had been given a whole bunch if big-as-a-beer-can caps for building power supplies, etc.) Getting hit by that would kill a guy for sure. We've come along way, baby!

riggerrob 643 #48 April 16, 2005 How soon until we see capacitors powering short-range airplanes (crop dusters, sight-seeing, skydiving, etc.). Can you imagine a jump plane quietly pulling up to the loading dock, ground plugging in a cable, a leisurely 4 minute loading process, then taking off with only wind noise?
