Most of us these days find battery life an annoying issue, as our increasingly puissant personal gadgetry uses juice faster and faster. Few, however, find batteries as troublesome as modern-day soldiers do - burdened as they are with lasers, optics, radios, monocle displays and other electronic paraphernalia. Adding insult to …
"capacitive and faradaic energy storage functions"
Aren't these different names for the same thing?
Or isn't a Farad a measure of capacitance?
Capacitors to boost alkalines?
I invented this years ago :-). Put a low-leakage electrolytic across the cell of an analog quartz clock, and you get much more life out of the cell. The mechanism draws power in pulses once a second, and the cap provides the pulse instead of the cell.
Wireless power, something that appeared to be possible back in Tesla's day.
They just need to have a word with my kids. Their Wii controllers NEVER run out of batteries, according to them. I just need to figure out where all the batteries I buy actually are going.....
More effort on DARPA descriptions please
I remember when DARPA descriptions were sure-fire keyboard-ruiners. Like how about this gem :
"The Pentagon's famous bad-boy scientists, DARPA* - who slap the pendulous jowls of established wisdom with the gauntlet of disregard ?"
Or this one :
"the famous Pentagon research bureau which, when scrumping apples from the tree of knowledge, ignores the low-hanging fruit in favour of the harder-to-reach pomaceous treat which often turns out to be beyond its reach."
"DARPA* - who are to ordinary insane scientists in their dungeon laboratories as platinum-selling popsters are to teenage-saddo garage bands"
Nowadays you hardly even seem to be trying Lewis. "renowned Pentagon brainiac-breeding bureau" - not bad, but not brilliant.

Where do they buy their batteries?
I bet the bunny is laughing all the way to the bank!
Faradaic means electrochemical - capacitance is the result of ion separation rather than electron separation as in a conventional (physical) capacitor.
Whatever happened to..
The miniature turbine and direct drive generator manufactured (iirc) by photoetching and miniature machining. I think it was right in the 10-20W range so battery replacement was definitely part of their game plan.
Give us some credit.
