I'm not sure about the collecting it at home exactly how you'd produce power from it in that way. 
We do in some parts of the UK use human waste - once it’s had tertiary treatment, it can be dried out, produce a cake and that is actually used at the likes of some cement kilns and some power stations.  So, that does actually happen.  A lot of it still has good nutrient in it and most places, once it’s treated, it’s still used as a good old fertiliser!
