I don't know squat about capacitors but that is pretty neat. One of them look like one of those new optima battery.

Interesting, I had to go look at these. From what I got from the data sheet is it will do as the video shows, but that's about $300 worth of caps on the assembly. That's not too bad but they have a life about the same as a normal battery. The big problem I see is they are only rated to about 150 degrees F, so under the hood in summer is not a good place for them. I'm sure they can improve on this. The good is they seem to work at lower temps than regular lead/acid.

thanks for the info!

i thought it was a interesting experiment. technology keeps moving forward faster than i can keep up. perhaps insulating a setup such as this or air cooling it could help prolong the lifespan and maybe i would be able to justify using such a setup instead of buying these heavy napa batteries or the optima. the whole reason i found this appealing was because of the obvious weight reduction. i'm too young to have back pain but i experience it daily and i know some of our other members have health issues or are in physical situations where lifting a heavy car battery is not a option. it would be great to perfect something like this to save our backs and to keep from bowing a shelf or something...

I would think that one more advantage with the capacitors is that they won't rust our battery trays and inner fenders. If these things actually catch on and go into production then the price will probably come down.
