I was listening to a Security Now podcast today and mention of some serious super caps was made. Does anyone have an idea if this is technology that is likely to come to fruition soon?
Sounds a lot like "Pie in the sky", Wes. G> At first I thught it might be a variation on "switched" capacitors such as are used in filters.

Well, Super Capacitors exist and they have been proposed for a variety of uses. I don't know if the claims are "pie in the sky" or not.

last year. They use them in hybrid city buses for energy recapture, very short storage time, lots of cycles/day.

I have been watching and waiting for EEStor to actually release some type, any type, of product for quite some time. Nothing yet. Last big news was a deal with a large military contractor (Boeing? IIRC...which I probably don't) to supply all power storage products for a whole slew of military gear. The deal was done behind closed doors. No details released.
If they actually have some form of ground breaking technology, they sure are doing a great job of hiding it. Dave

Super caps have been around in one form or another for decades now, fractional farad caps have been used for years for retaining settings on electronic equipment during outages. You can get a 1F for fairly cheap change now. They're basically two aluminum plates with a paste of acid and carbon black between them, the internal resistance is fairly high and the working voltage is pretty low. The high capacitance is because of the extremely large surface area of the carbon black. So any practical traction use for them needs to have them in both series AND parallel and then you still have to overcome the exponential discharge curve inherent with capacitors. Would take some fancy electronics to do that, but it would be doable. The discharge curve is far inferior to just about any storage battery type, though. You'd probably end up cutting off discharge with about a third of the charge left just because the voltage would get too low to practically step up to working voltage.

You don't remember correctly. My employer, Lockheed Martin bought into EEStor, when this first happened we got lots of stuff in email and company news. I haven't heard anything in a long time.

That is interesting.... Hum - I have a data sheet somewhere that a like unit - a high tech version - was a timing circuit part and was used in covert operations for months in length during Viet Nam.
These and the others are second or third generation and likely lower cost.
