Urine-powered generator produces six hours of electricity per bathroom break -- Engadget
Also has the potential to be a biological hydrogen bomb.
Someone's taking the piss here.
Not unless you're drinking Red Bull with tritium. This thing probably less explosive potential than a jerrycan of gas.
The Second Law of Thermodynamics agrees with you, since this is a variation on the water-electrolysis theme. Splitting water into hydrogen and oxygen, then recombining the hydrogen to produce the same amount of water again, can never produce a net energy output.
this thread is not funny
As gross as it is, I can see the practical applications here.
I'm all for new sources of energy, but piss isn't necessarily a "clean" energy fuel.
Then again, poop is used as a fuel source for some things around the world, so...
This isn't anything revolutionary, and it really doesn't even create energy. It takes more energy to separate the hydrogen atoms than this can produce from using them as fuel.
You have to power it to make it generate power.
Hey, at least its an easily renewable energy source. It it's yellow let it power a generator.
You're a party pooper.
what no Bear Grylls joke?
True, but combining it with a solar cell could convert a waste product into a storable, transportable energy source. Until battery/supercapacity technology becomes more advanced and ubiquitous, this could be something that actually be useful in that part of the world, even if it's something of a really circumlocuitous route around the problem.
I pray for the day we have piss power cars. Imagine it, instead of gas station, piss stations.
Wow,this really pisses me off.
But seriously, that's actually kinda cool. Even if it's piss poor. Sorry.
That's true, you can use solar power to electrolyze water, but, unfortunately, that doesn't seem to be what the article is promoting this as.
A lot of people get confused, thinking (probably): you can put a given amount of energy into extracting fuel from oil or coal, then burn the fuel for a much larger amount of usable energy. What they forget is that you don't end up with the original petroleum feedstock. When burning hydrogen and oxygen, the product is water.
Anyway, you'd be better off using the electrical output of the solar cell directly, instead of losing 50% of it electrolyzing water, and then losing more than 70% of what's left in the generator. If a person can't afford a bank of 1910-tech Edison batteries, then that person probably can't afford a solar panel, either.
If this technology was widespread today, that lady who was fined $2,500 could of just used the excuse that her kid was fueling the house generator.
Splash station. (or 'slash station' if you're a UKer)
Imagine the new energy 'gold rush'...
Also something about a 'power (golden) shower'.
Okay, I'm empty dry now...
