Recent research has shown that human waste contains a high level of energy that is usually just flushed away. In Washington state and other areas, power plants are being built that use sewage as the input for fuel cells. http://on.msnbc.com/poo-power
Other scientists have working on similar projects – using bacteria to break down waste and release methane, which can be used in fuel cells.
There is also a patent for a process of converting sewage into batter power: http://on.msnbc.com/sewage_patent through a similar process of using bacteria.
This concept could be implemented in two ways:
- A collective sewage plant that coverts waste to fuel cells (downside: high initial cost of plumbing households).
- Individual family apparatuses that can be given, with associate costs paid for by selling the batteries.
Either way, profits from selling power or batteries would be used to subsidize health products, such as nutrient packs, condoms, formula, vaccines and other forms of preventative care.
