Ultracapacitor LED Flashlight Charges In 90 Seconds 131
Iddo Genuth writes "The California based company 5.11 Tactical has recently introduced a new innovative flashlight — 'Light For Life' UC3.400. Unlike regular flashlights requiring constant battery changing this new LED torch offers a rechargeable battery that can be recharged in as little as 90 seconds using ultracapacitor technology. Various military and rescue units might benefit from this new development, ensuring them a light source at all times."

ensuring them a light source at all times.
Except those 90 seconds.
In which you will be eaten by a grue.

Yeah and it'll be like every PC FPS with a flash light (HL2/F.E.A.R etc) where it lasts 30 seconds at a time.

These two technologies are not mutually exclusive.
Except perhaps if their respective patent holders refuse to cross-license to each other.

how quickly does it self-discharge?
TFA says that it provides light for up to 90 minutes. But it uses a capacitor to store charge, so I imagine it could discharge very rapidly under the wrong conditions.
I think you are shorting him on the shocking details of ultra capacitor discharge.

But you have to look at the big picture.
Lets say during an average 3-hour shopping experience, you may look at 15 items, and impulsively buy 2 items. Each impulsive buy brings you 10 mG* of fun.
2 * 10mG = 20mG / 3 hrs = 6.66 mG / hour of fun (roughly)
Guessing from your slashdot ID, you're fairly young, probably just past being teenage (again, very roughly.) Based on your age, looking at items that you might buy, but not actually buying them should give you about 5 mG of fun per hour.
6.66 mG + 5 mG = 11.66 mG per hour of fun.
B5 Geek shopping with you would admittedly remove much chance of you impulsively buying any items, but there's still the remote possibility of you buying one (say, for example, while he goes to the bathroom, or gets distracted counting ceiling tiles)
We'll say that there's roughly a 20% chance of impulsively buying an item with him around.
6.66 mG * 20% = 1.33mG of fun per hour from buying items
But the joy gained by admiring the disgusted looks from the many females you'd be passing in the mall, and the sighs of boredom from the retail clerks while B5 explains to them the features of the products they're selling combined would provide at LEAST 10 mG of fun per hour.
10mG + 1.33 mG = 11.33 mG per hour of fun.
So you see, while shopping with B5 Geek, you would really only be losing roughly 0.33 mG of fun per hour.
Combined with the fact that you could probably convince him to buy you lunch (He's probably lonely enough to pay just for your company) shopping with him might not be so bad after all.
*mG = milliGrin

That's actually a myth, the flashlight in Doom 3 is actually grue powered.

You know slashdot is not what it used to be, when the explanation for the joke is Score:5, Insightful, and the actual joke is Score:2
