I worry about energy density. I think you might be better off eating a healthy, fiber rich diet then drying and burning your dung. |
|
| |
!! "..drying and burning your ... "!!! Oh, "d*u*ng". Okay, then. |

humans don't produce enough methane to do this. It would take the whole village just to warm up one can of beans. |
|
| |
They also sort of do this with cow's already save for the fact that they use it to generate electricity. the equipment to refine the gas costs over a million though, so it's only economical for large farms with grants. |

Farts are mainly carbon dioxide and nitrogen. I think it could be done by way of fractional distillation. Hydrogen sulphide, which is supposedly not present in all farts, has an unusually high boiling point and could be separated quite easily but is also quite toxic. It can't be that concentrated in farts even when it's present because of that toxicity. Methane would be a better bet because its toxicity is low. The mixture would then be nitrogen and methane. |

You'd be better off with poo. |

What is the ratio of the potential energy of the flammable gasses in a fart, to the kinetic energy of the fart as it rushes forth from arse to world? Would it not be better to install an anal turbine? |

That's rediculous. Do you have ANY idea how many farts it
would take to warm up a cow?? |
|

In India they're going the digester route. They don't
see the sense in pumping to poison our bio-
products. Very small scale units digest to methane,
to cook with. For the Mother of all Smelly Farts
make baked beans up as normal but add bacon in
uncooked instead of cooked. |

metarinka, the equipment needed to separate out
the methane from the gas produced by
biodigesting the poo of few thousand cows might
cost over a million dollars, but: |
|
| |
For cooking, heating, and on-site energy
production, the gas from a biodigester doesn't
need to be purified into methane -- it can be used
as is. It only needs to be purified if one wants to
sell it to the local utility company. |
|
| |
Furthermore, biogas digesters can be made small
scale. |
