SUMMARY

Ultra capacitors are now available at Digikey, including a 110 Farad capacitor with a working voltage of 2.5V priced at $31.20. The discussion highlights the potential of ultra capacitors, particularly their low equivalent series resistance (ESR), which is as low as 0.18 milli ohms for a 5000 Farad version. The conversation also touches on the feasibility of using ultra capacitors in lightning projects, questioning the voltage ratings of lightning arresters compared to the millions of volts associated with natural lightning. For further details, Maxwell Technologies' ultracapacitor products can be explored.

PREREQUISITES
  • Understanding of ultra capacitors and their specifications
  • Familiarity with equivalent series resistance (ESR) concepts
  • Knowledge of voltage ratings and electrical safety standards
  • Basic principles of lightning and electrical discharge phenomena
NEXT STEPS

Ultra caps have come to Digikey ...YAY..
you can now buy a 110 Farad capacitor with a working voltage of 2.5V for $31.20 in quantities of one..
for more info google ' UltraCapacitor ' or the newest ' nanogate ultracapacitor.'
or check out what's happening at Maxwell technologies

lots of stuff to look foward to in the future..
 
Engineering news on Phys.org
the reason i posted that, was , ehem , *clears throat , hesitates*
in the hope that soon someone with a lot of cash , will fund a lightning project..
with ultra capacitors super low ESR ( equilivent series resistance ) on the order of a few tenths milli ohms, (0.18 milli ohms for the 5000 Farad version) it seems to me that ten thousand of them stacked upon each other would only equal 1.8 ohms.. i realize that 10k @ 2.5V only eqals 25,000V ..
Howcome lightning arresters are only rated @ 6 k V ?
there really isn't much new data out there on lightning , same old sites..
although i havnt checked the U of Florida site lately.
anyway yes lightning is on the order of millions of volts , but is it really ?
what i mean is it must loose some of its voltage traveling through the atmosphere..
with todays super fast electronics , you would think that we could detect an over-voltage situation and quickly switch out to ground when the bank is full..
