Via guido I found this wonderful invention, and a call for more efficient spending of DfID funds on such ideas.
I have a considerably simpler idea on how to achieve this goal: abolish the DfID outright, and use the money as a drop in tax from which we can donate to charity ourselves.
It appears over the last decade they have had enough spare cash to indoctrinate our children and engage in pure politically motivated activities; taking that back alone would give us enough money to buy over 800000 units per year which as they can filter 6000L of water and an average human male requires ~2L a day would last 3000 days or a little over 8 years by which point replacements would become commercially viable for a healthier African population.
Does anyone know how to create a transferable web badge? I want to start a campaign to abolish the DfID and include a pledge to use the money saved in lower taxes to donate to worthy charities of our choice; charity not only begins at home but also flows from there; government cannot be "generous" or "charitable" because by definition it does not have any of it's own money- I would not be considered a charitable giver by the judiciary if all the money I gave was stolen/mugged from other people- why is government different?
