It looks great, but who's going to pay for it? Two cents per shit for a family of 8, assuming once daily, is $58 for a year's supply. 20% of Kenyans - apparently the market this is aimed at - earn less than $438 p.a according to Unicef.
Do we expect them to give up 13% (or 7% if both adults work) of their gross income for shit-bags? What do they gain from this? Are they throwing this shit on their own allotments? I doubt it.
Could be very effective as an investment of foreign aid. In any case I think this should be targeted as much at the developed world, who have leisure and compost bins and gardens etc, as at the third. All of us need to start getting value from our waste, not just poor people.
