NEW Supercap...Useful?

Aerogel Supercap

I found this at the solarbotics site, I believe it's new-ish, I'm sure it's small and I know these caps are useful. Has anybody seen it before? Anybody THINK they can make a model from it?? Looks really nice, especially for 1 gm!

Specs:
1 Farad
2.5 Volts
.4 Ohm Internal
11mm L *8mm OD
1 gr


On a side note, I believe the Cap from the Aero-X from Toys-R-US is the .33F model also listen on this site. If .33F can fly like that, than 1 F can be awesome!

Its nice,
Have a look here http://electronics.howstuffworks.com/capacitor2.htm
Basically that will give you 125 seconds of 20mA at 2.5Volts at 1gr

The Kokam 20mA LiPo weights in at 0.7gm and gives you about 20mA at 3.6V for about a hour ( realistically maybe 40 minutes ) Thats about 20 times more capacity.

The capacitors are good because they can give higher discharge currents but their capacities are still lower than LiPos.

Cheers

Yeah....I'll have to look it up, but I read in an Electronics magasine that a company is wokrin on a better supercap, to have capacity rivaling LiPos buy like 2007 or something. That sounds good too :-) I like LiPos cause you can quick-charge them and abuse them alittle, and they dont blow up :-P (under most conditions)
