Sorry, I forgot to mention, my local village, Mullagh, has decided for their project, to install a slurry digester, the methane gas thereby produced will be used to generate electricity. Not only slurry (which is becoming a huge issue in Ireland as run-off is causing what should be potable water to be un-drinkable without very expensive treatment {see the Cryptosporidium thread}), but any compostable material can be mixed in.

All being well, the village will be self-sustainable with it's electricity supply!
