Could we collect our own waste at home and use that as a source of power?


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 itís 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 itís treated, itís still used as a good old fertiliser!
