Fecal Matters

Cow lampI shit you not- French environmentalists have concocted a way to produce electricity from fermented poop. Cow poop in particular is the environmentalists’ anticipated source of renewable energy, taking into consideration that there are currently 20 million cows in France. It is estimated that with the number of cows in France, the amount of electricity that can come from one cow and with the amount of electricity that the French use in a year, cow poop electricity (or le biogaz) could account for a staggering 1.6% of all French electricity. Of course, biogaz can also come from the poop of other animals. What really makes le biogaz a breakthrough is that it has the potential to eliminate the need for fossil fuels (in the distant future when the process is perfected) in the production of electricity. The poop method emits no carbon dioxide into the atmosphere. But how is this miracle of science possible and from what did these environmentalists get their inspiration? Well I’ll tell you!

poopImagine if you will, more than 3.5 billion years ago when the first organisms (prokaryotes) on Earth made their harrowing journey through the primordial ooze. The atmosphere at this point in history had no oxygen. The prokaryotes used carbonic gas and hydrogen, making oxygen and methane. When autotrophes hit the scene, they put a lot of oxygen into the atmosphere. For the descendants of our little friends the first prokaryotes, the air became unbreatheable. They fled to other spaces and eventually ended-up in the digestive systems of animals. Animals live in symbiosis with these little critters as they aid in the digestive process.

To make le biogaz, poop is fermented in an oxygen-free cistern to create methane gas. When burned, the methane can be converted into electricity. It’s as simple as that.

So the next time you take a dump, consider its creative potential and put it to good use. Global warming ends with you!

    The French have always been good at making uses out of shit.

    The French have always found uses for shit.

    Please delete above comment.

    Cyn1c, you got beat fair and square. Just let it go.

    This is really interesting, but why are they just using cow poop? Couldn’t they fry up all types of shit? Why aren’t they hooking up to the local sewer system?

    Rachael Brown

    Well, if they do start to use biogas to produce electicity (it’s only really in the proposal stages as an energy source), I imagine that they will use all kinds of excrement from all kinds of livestock. Hooking up the sewer system might prove to be a bit of a problem because of all the things people tend to flush (goldfish, condoms, tampons and any number of mistaken items). Or at least that’s my best guess. Using human feces was never really mentioned as an option. Cows would be a great source since there are so many of them and because cows produce so much poo. Cows alone would account for a large portion of the biogas production. However, if you imagine how much biogas could be made from cows after you account for fertilizer production and the like, you come out with about 1.6% of French electric consumption. I doubt that all the livestock in France will be able to poop enough to completely rid France of burning fossil fuels for electricity but they would be able to at least burn less.

    I just read that if the “digestat” (the fermented poo) is thought to have impurities of some kind, it can be incinerated or filtered and stored. So who knows whether or not they want to use human poo.

    Bryan Klausmeyer

    My question is this: does anything prevent France from not smelling like a shit box after they use biogas as an alternative fuel source? I suppose there’s an obvious joke in there somewhere, but I’m curious as to how they filter out the horrid stench of burning fecal matter.

    Rachael Brown

    I thought about that too. I imagine that the surrounding area of the biogas plant would smell like certain parts of Deleware but I suppose that we won’t know until they try it out.

    I think that “3 million year” should’ve been 3 BILLION years. ;-)

    Bryan Klausmeyer

    I think you both mean 3,000.

    Rachael Brown

    It actually should have been 3.5 billion, which is why I should read things before I post them :-p

    But if I change it to 10000, that’ll really screw people up.

    Rachael Brown

    BTW There was no mention of using human poo that I could find. In fact, there were specific places that said animal.
