Can Urine Rescue Hydrogen-Powered Cars?
thecarchik writes with this interesting excerpt: "It takes a lot of energy to split hydrogen out from the other atoms to which it binds, either in natural gas or water. Which means energy analysts are skeptical about the overall energy balance of cars fueled by hydrogen. Ohio University researcher Geraldine Botte has come up with a nickel-based electrode to oxidize (NH2)2CO, otherwise known as urea, the major component of animal urine. Because urea's four hydrogen atoms are less tightly bound to nitrogen than the hydrogen bound to oxygen in water molecules, it takes less energy to break them apart."
first piss!
Sperm and now urine? I'll take a guess and say the next article will be about crap.

Try pissing in my gas tank now!
The cars powered by this will smell like Bourbon Street.

Cool. We burn our pee in the car, collect pure water from the tailpipe, drink the water and pee again.
Perpetual urination FTW.
Don't worry. I'm sure you still can hang around the rest areas and make some money.
Peeing in my neighbors gas tank will no longer have the desired effect.
Urea is a common component in a lot of industrial applications, notably cosmetics, soap and animal feed. No need to really source it from the sewer, industrial vats make this stuff every day.
Telling women what exactly "Urea" is in the ingredients of their makeup case is great fun...

the fuel will be called urinine, because after a lot of beer, I'm way way past urin8
Some drink at the fountain of knowledge. Others just gargle.
What they didn't tell you is that it takes about 33 times longer. They're not sure why, though.
Not to mention that the cheesing community will be outraged.

I get the impression you don't get out much...;)
I'd have to piss somewhere in the neighborhood of 40 gallons a day to have enough fuel just to handle my daily commute.
So that just gives you an(other) excuse to get very drunk at work. :)
"City hall" in German is "Rathaus" Kinda explains a few things......
but in this case it's a good thing.

I'm not entirely certain you've succeeded in changing my opinion of hydrogen, but you've definitely made a change in my thinking.
Now if I could only find my car keys ...
Every time I see people complaining about hydrogen storage, I find myself wondering what's so hard about it. You can store hydrogen fairly densely and easily by just attaching it to carbon atoms in a roughly 2:1 ratio. What's more, we already have the infrastructure in place to transport and use hydrogen that's been stored in this manner. And, even better, no high pressures, low temperatures, or special materials are required!
If it works, it would be a very green... er... yellow solution.
Yeah, but that relys too much on using dangerously toxic carbon ....
.
I've heard that a few grams of carbon injected into a polar bear at 100m/s can kill it instantly.

Way to dangerous to use in cars and vehicles.

they are just taking the piss out of us.
After logging in slashdot still does not take you back to the page you were on. It's been that way for 20 years.
I like the idea. Anything that involves aiming a stream of urine towards our national leaders is fine by me.
Slow down, cowboy! It has been 4 hours since you last posted. You must wait another few hours.
Bartender, I need two gallons of beer for the road!

A few grams of lead can be injected into most animals with the same effect, it just depends on your aim.
Anything can be found funny, from a certain point of view.
...to pissing on a spark plug. It may now do good.
Let's face it, most of us are scoffers. But moments before zero hour, it does not pay to take chances.
Now if I could only find my car keys ...
Have you tried Google? They're doing some really amazing stuff with their engine lately.

I don't care how much less it is... There is simply not enough urea made in the entire country on a daily bases to produce enough H2 for fuel for even a small city.
I disagree. There is easily 40 gallons of urine produced daily for each person on the continent. You're only taking into account human produced urea... but any urea would do. There's a lot of horses and cows in this country, they make it too... and if we could tap into the urea produced by rats... but this is assuming cows, horses and rats don't need it for their own cars.
