Sigh.  Physics fail.
Kilowatts is not a unit of energy, it is a unit of power -- in other words, a rate of energy.

In order to tell me how much energy this 1kg of aluminum powder can make, you have to tell me how long this 220kW of power will last.  If I have a hypothetical device that requires 220kW of power to work, can I run it for a second?  A minute?  An hour?  The difference between 220 Kilowatt-microseconds and 220 Kilowatt-hours is a pretty farking enormous amount of energy.

Meaning when they tested it, they didn't have a premise. So rather it was "this thing makes hydrogen from liquids. I'm going to make it produce hydrogen from my pee! Heheheh"

I didn't say it's caught on universally. But it isn't uncommon when referring to a member of the US Army. Government docs, press releases, etc. typically capitalize it and a lot of publications follow along if for no other reason than to maintain consistent style. I was in the Army at the time the change was being implemented, so I always notice when I see the word whether it is capitalized or not.

Any ailment you have in the Army can be solved by either drinking water or taking Motrin. Sometimes both if you're really bad off, like with a compound fracture.

I remember in basic, you never really saw a doctor. sick call was staffed with a bunch of lower enlisted who diagnosed you with a flow chart. They (and this is how they actually did it) asked you a series of questions and followed the lines. Like "are you snotty?" If snotty, turn to page 3. "Is your snot yellow or green?" If green continue to page 6. But it really didn't matter what you picked because all the lines ended up on the last page which said "give Motrin."
I had a really bad cough for several days, so I went to sick call where an Army doctor told me "Sometimes people cough just because they want to cough. My advice to you is to stop coughing." And that was it. Didn't listen to my lungs, take my temp or farking anything. The next day I was in the hospital with pneumonia. Stayed for 3 days.

From your quoted text, the answer appears to be 3 minutes.


The phrasing "IN 3 minutes" instead of "FOR 3 minutes" implies that this is the speed of the chemical reaction, not the amount of time that power is provided for.  After all, the purpose of this aluminum powder is to liberate hydrogen for use in fuel cells, and reaction speed was the critical part of this discovery, after all.

But the thing is, the idea that a certain amount of hydrogen provides a certain level of power doesn't even make any sense anyway -- such a figure would be determined by the design of the fuel cells and how they're connected to each other.  It has nothing to do with the powder.  One COULD determine the total amount of energy a given amount of hydrogen would provide (for a given fuel cell efficiency), but they didn't give us that, because apparently they don't know what energy is or how it is measured.

Seems the military has always been infatuated with the power of pee?
From the Civil War - they collected urine to make gunpowder (Author(s) Unknown):

CONFERATE VIEW OF IT
John Haralson, John Haralson-you are a wretched creature;
You've added to this bloody war a new and useful feature.
You'd have us think, while every man is bound to be a fighter,
The Ladies, bless the pretty dears, should save their pee for nitre.
John Haralson, John Haralson, where did you get the notion,
To send the barrel 'round to gather up the lotion?
We thought the girls had work enough to making shirts and kissing,
But you have put the pretty dears to Patriotic Pissing.
John Haralson, John Haralson, pray do invent a neater,
And somewhat less immodest way of making your saltpetre.
For 'tis an awful idea, John, gunpowdery and cranky
That when a lady lifts her skirts, she's killing off and Yankee.
YANKEE VIEW OF IT
John Haralson, John Haralson, we've read in song and story,
How women's tears, through all the years, have moistened fields of glory.
But never was it told before, how 'mid such scene of slaughter
Your Southern beauties dried their tears and went to making water.
No wonder that your boys were brave; who couldn't be a fighter,
If every time he fired his gun, he used his sweetheart's nitre.
And vice versa, what could make a Yankee soldier sadder,
Than dodging bullets fired by a pretty woman's bladder?
They say there was a subtle smell which lingered in the powder
And as the smoke grew thicker and din of battle louder,
That there was found in this compound one serious objection-
No soldier boy could sniff it without having an erection!!

"We have calculated that one kilogram of aluminum powder can produce 220 kilowatts of energy in just three minutes," said Dr. Anit Giri, also an ARL researcher.

Holy sheit! That is 1,222 watts a second. That is A LOT of raw energy (potential). Is it just a catalyst? Is it exothermic? How much water (or urine) is "used". What other elements are released (pure O2 burns quite well)? What remains? What happens after 3 minutes?

This is quite a big deal if it can be properly harnessed, especially in a portable unit.

Holy sheit! That is 1,222 watts a second. That is A LOT of raw energy (potential).


No, that isn't what that means.
In fact the researcher's statement doesn't even make any sense from a physics perspective.  220kW isn't a measure of energy, it's a measure of power -- which is a RATE of energy production.

220kW/3 minutes doesn't mean 1.222kW/second. A rate is an instantaneous reading, like speed.
In fact, let's make some analogies here to illustrate. If Watts = speed in mph, then: energy = miles, and watts/second = acceleration.

What this researcher basically said is, "We made a new fuel, and 1kg of it can make a car go a distance of 120mph in 3 minutes!"

First of all, does that make any got-damn sense?  No. It does not. It doesn't make sense on any level. Even if they said it could make a car go 120mph FOR 3 minutes, that would make more sense, but still -- doesn't the actual speed depend more on the car itself?

Second of all, if you divide that 120mph by 3 minutes, does that tell you how many miles it would actually go?  No.
Does it even make any sense to do that calculation?  Very likely not. What it gives you is a rate of acceleration of 40mph per minute. That isn't nonsense, but in this case it likely doesn't correspond to anything. It certainly doesn't tell you how far the car will go.

So the calculation you're doing -- dividing 220kW by 3 minutes -- is giving you an "acceleration" for an increase in wattage that probably does not correspond to anything actual. It is certainly not telling you how much energy this reaction is producing.

Also, energy isn't potential.  Electrical potential is measured in volts, energy is measured in joules.  Voltage would depend on the design of the fuel cell itself.

My best guess is that the "3 minutes" part is talking about how long the reaction takes to separate the hydrogen in the water and that the "220kW" figure came from a researcher who misspoke, or who was misquoted. It can NOT be the case that the reaction itself actually produces that much power for that amount of time.

The reaction produces hydrogen for fuel cells, not electricity.  The hydrogen provides an energy pool to power those fuel cells, but the amount of power those fuel cells produce depends on how those fuel cells are designed. In order to give us energy, they'd either have to give us a number measured in Joules, or they'd have to tell us how long their fuel cell stack could sustain a 220kW output.
