anyone here read the NEW SCIENTIST magazine? awesome stuff. anyway, this relates to an article in a recent issue- a scientist hypothesized that pandas must have some serious bacteria in its stomach and digestive tract that allows it to digest bamboo being the tough stuff that it is. so he got a order of panda poo from some zoo, separated 5 strains of bacteria from the sample, then placed the strains into 100kg of vegetable waste. within two weeks the waste was reduced to 3kg of material, all the while through the whole process producing hydrogen which the scientist then used to power a fuel cell. excellent. what logic. i love that magazine.
